Other notable relative contributors included an overweight in Qualcomm (+70%) and a non-benchmark stake in Broadcom (+87%). This period we decreased our positions in Qualcomm and Broadcom. &lt;span&gt;&#160;&lt;/span&gt;&lt;/span&gt;&lt;/li&gt;&lt;li style="margin:5px 0px 2px 24px;padding:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;In contrast, the largest detractor from performance versus the benchmark was stock picking in health care. Security selection in real estate, primarily within the equity real estate investment trusts (REITs) industry, also hampered the fund's result. &#160; &lt;/span&gt;&lt;/li&gt;&lt;li style="margin:5px 0px 2px 24px;padding:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;The biggest individual relative detractor was our non-benchmark stake in Teradata (-36%). The second-largest detractor was an overweight in Zimmer Biomet (-25%). This period we decreased our positions in Teradata and Zimmer Biomet. A stake in Hawaiian Electric Industries returned -66% and also notably hurt. Hawaiian Electric was not held at period end.&lt;/span&gt;&lt;/li&gt;&lt;li style="margin:5px 0px 2px 24px;padding:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;Notable changes in positioning include decreased exposure to consumer discretionary and health care. &#160; &lt;/span&gt;&lt;/li&gt;&lt;/ul&gt;

This move, approved by the Board of Trustees in June 2023, was deemed in the best interest of shareholders. The new ETF and its former corresponding fund have identical investment objectives and fundamental investment policies and have substantially similar investment strategies. Returns prior to the conversion are those of the former corresponding fund. Fidelity believes that the conversion will provide multiple benefits for investors of the fund, including lower net expenses, additional trading flexibility, increased portfolio holdings transparency and the potential for enhanced tax efficiency. Effective March 1, 2024, the fund's fiscal year end changed from August 31 to June 30.&lt;/span&gt;&lt;/div&gt;

Amid this favorable backdrop for higher-risk assets, stocks continued their late-2023 momentum, powered by signs of continued U.S. economic strength. &lt;/span&gt;&lt;/li&gt;&lt;li style="margin:5px 0px 2px 24px;padding:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;Against this backdrop, security selection was the primary contributor to the fund's performance versus the benchmark, led by industrials. Stock selection in consumer discretionary, consumer staples and materials also boosted the fund's relative performance. &lt;/span&gt;&lt;/li&gt;&lt;li style="margin:5px 0px 2px 24px;padding:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;The top individual relative contributor was an overweight in Super Micro Computer (+240%), which was our top stock holding. Overweight holdings in Abercrombie &amp;amp; Fitch (+376%) and Carvana (+160%) also notably helped. Abercrombie &amp;amp; Fitch and Carvana were among the fund's largest holdings at period end. The stake in Carvana was established this period. &lt;span&gt;&#160;&lt;/span&gt;&lt;/span&gt;&lt;/li&gt;&lt;li style="margin:5px 0px 2px 24px;padding:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;In contrast, the biggest detractor from performance versus the benchmark was stock picking in real estate, primarily within the equity real estate investment trusts (REITs) industry. Security selection in health care also hampered the fund's result, as did an overweight in communication services. &lt;span&gt;&#160;&lt;/span&gt;&lt;/span&gt;&lt;/li&gt;&lt;li style="margin:5px 0px 2px 24px;padding:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;The biggest individual relative detractor was an underweight in MicroStrategy (+302%), which ended the 12-month period as a top-10 fund holding. This was an investment we established this period. A second notable relative detractor was an overweight in CommScope (-78%). A stake in Omnicell returned -60% and also notably hurt. Omnicell was not held at period end. &lt;span&gt;&#160;&lt;/span&gt;&lt;/span&gt;&lt;/li&gt;&lt;li style="margin:5px 0px 2px 24px;padding:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;Notable changes in positioning include decreased exposure to real estate and consumer discretionary. &lt;/span&gt;&lt;/li&gt;&lt;/ul&gt;

This move, approved by the Board of Trustees in June 2023, was deemed in the best interest of shareholders. The new ETF and its former corresponding fund have identical investment objectives and fundamental investment policies and have substantially similar investment strategies. Returns prior to the conversion are those of the former corresponding fund. Fidelity believes that the conversion will provide multiple benefits for investors of the fund, including lower net expenses, additional trading flexibility, increased portfolio holdings transparency and the potential for enhanced tax efficiency. Effective March 1, 2024, the fund's fiscal year end changed from February 28 to June 30.&lt;/span&gt;&lt;/div&gt;

Amid this favorable backdrop for higher-risk assets, stocks continued their late-2023 momentum, powered by signs of continued U.S. economic strength. &lt;/span&gt;&lt;/li&gt;&lt;li style="margin:5px 0px 2px 24px;padding:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;Against this backdrop, security selection was the primary contributor to the fund's performance versus the benchmark, led by industrials. Stock picking in information technology and consumer discretionary, and positioning in consumer staples and communication services, also boosted relative performance. &lt;span&gt;&#160;&lt;/span&gt;&lt;/span&gt;&lt;/li&gt;&lt;li style="margin:5px 0px 2px 24px;padding:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;The top individual relative contributor was an overweight in Vistra (+233%). Overweight holdings in AppLovin (+217%) and Robinhood Markets (+126%) also helped. &lt;span&gt;&#160;&lt;/span&gt;&lt;/span&gt;&lt;/li&gt;&lt;li style="margin:5px 0px 2px 24px;padding:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;In contrast, the biggest detractors from performance versus the benchmark were stock selection and an overweight in health care. An underweight in energy also hampered the fund's result, as did stock picking and an underweight in financials. &lt;span&gt;&#160;&lt;/span&gt;&lt;/span&gt;&lt;/li&gt;&lt;li style="margin:5px 0px 2px 24px;padding:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;The largest individual relative detractor was an underweight in CrowdStrike Holdings (+161%). We established a position in the stock during the period. Other notable relative detractors included an overweight in 10x Genomics (-66%) and an underweight in Constellation Energy (+121%). The latter was an investment we established this period. &lt;span&gt;&#160;&lt;/span&gt;&lt;span&gt;&#160;&lt;/span&gt;&lt;/span&gt;&lt;/li&gt;&lt;li style="margin:5px 0px 2px 24px;padding:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;Notable changes in positioning include lower allocations to health care and real estate. &lt;/span&gt;&lt;/li&gt;&lt;/ul&gt;

This move, approved by the Board of Trustees in June 2023, was deemed in the best interest of shareholders. The new ETF and its former corresponding fund have identical investment objectives and fundamental investment policies and have substantially similar investment strategies. Returns prior to the conversion are those of the former corresponding fund. Fidelity believes that the conversion will provide multiple benefits for investors of the fund, including lower net expenses, additional trading flexibility, increased portfolio holdings transparency and the potential for enhanced tax efficiency. Effective March 1, 2024, the fund's fiscal year end changed from August 31 to June 30.&lt;/span&gt;&lt;/div&gt;

Performance was largely driven by a narrow set of technology-focused firms riding high-growth megatrends, fanned by enthusiasm for artificial intelligence. &lt;span&gt;&#160;&lt;/span&gt;&lt;/span&gt;&lt;/li&gt;&lt;li style="margin:5px 0px 2px 24px;padding:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;Against this backdrop, stock picks in the U.K. and stock picking and an underweight in Europe ex the U.K. contributed to the fund's performance versus the benchmark. By sector, security selection was the primary contributor, especially within industrials, where our picks in capital goods helped most. Stock selection in information technology, and picks and an underweight in consumer staples, also boosted relative performance, as did stock selection in health care, primarily within the pharmaceuticals, biotechnology &amp;amp; life sciences industry. &lt;span&gt;&#160;&lt;/span&gt;&lt;/span&gt;&lt;/li&gt;&lt;li style="margin:5px 0px 2px 24px;padding:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;The top individual relative contributor was an overweight in Rolls-Royce Holdings (+193%). This period we decreased our position. Other notable relative contributors included overweight holdings in Disco (+141%) and Wix.com (+98%). We decreased our investment in Wix.com during the period. &lt;span&gt;&#160;&lt;/span&gt;&lt;/span&gt;&lt;/li&gt;&lt;li style="margin:5px 0px 2px 24px;padding:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;In contrast, from a regional standpoint, an overweight in Asia Pacific ex Japan, primarily in Hong Kong, and security selection in emerging markets detracted from the fund's relative result. By sector, the biggest detractor from performance versus the benchmark was stock selection in communication services. Also hurting our result were stock picks and an underweight in financials, primarily within the banks industry, and selection and an overweight in consumer discretionary, primarily within the automobiles &amp;amp; components industry. &#160; &lt;/span&gt;&lt;/li&gt;&lt;li style="margin:5px 0px 2px 24px;padding:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;The largest individual relative detractor was an overweight in Genmab (-34%). Overweight stakes in Panasonic Holdings (-33%) and RWE (-23%) also hurt. RWE was not held at period end. &lt;span&gt;&#160;&lt;/span&gt;&lt;span&gt;&#160;&lt;/span&gt;&lt;/span&gt;&lt;/li&gt;&lt;li style="margin:5px 0px 2px 24px;padding:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;Notable changes in positioning include increased exposure to the Netherlands and a lower allocation to Sweden.

This move, approved by the Board of Trustees in June 2023, was deemed in the best interest of shareholders. The new ETF and its former corresponding fund have identical investment objectives and fundamental investment policies and have substantially similar investment strategies. Returns prior to the conversion are those of the former corresponding fund. Fidelity believes that the conversion will provide multiple benefits for investors of the fund, including lower net expenses, additional trading flexibility, increased portfolio holdings transparency and the potential for enhanced tax efficiency. Effective March 1, 2024, the fund's fiscal year end changed from August 31 to June 30.&lt;/span&gt;&lt;/div&gt;

Amid this favorable backdrop for higher-risk assets, stocks continued their late-2023 momentum, powered by signs of continued U.S. economic strength. &lt;/span&gt;&lt;/li&gt;&lt;li style="margin:5px 0px 2px 24px;padding:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;Against this backdrop, security selection was the primary contributor to the fund's performance versus the benchmark, especially within industrials. Stock picks and an underweight in consumer discretionary, and picks in information technology, also boosted relative performance, as did an underweight in consumer staples, primarily within the food, beverage &amp;amp; tobacco industry. &lt;span&gt;&#160;&lt;/span&gt;&lt;/span&gt;&lt;/li&gt;&lt;li style="margin:5px 0px 2px 24px;padding:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;The top individual relative contributor was an overweight in Nvidia (+190%), which was one of our biggest holdings. Other notable relative contributors included a non-benchmark stake in Abercrombie &amp;amp; Fitch (+120%), an investment we established this period, and an underweight in Starbucks (-19%). Starbucks was not held at period end. &lt;span&gt;&#160;&lt;/span&gt;&lt;/span&gt;&lt;/li&gt;&lt;li style="margin:5px 0px 2px 24px;padding:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;In contrast, the biggest detractor from performance versus the benchmark was security selection in health care, primarily within the health care equipment &amp;amp; services industry. Stock picking and an overweight in energy also hampered the fund's result. &#160; &lt;/span&gt;&lt;/li&gt;&lt;li style="margin:5px 0px 2px 24px;padding:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;The largest individual relative detractor was an overweight in Teradata (-33%). This period we increased our stake in the stock. The second-largest relative detractor was our non-benchmark stake in Bristol-Myers Squibb (-23%). An overweight in Lattice Semiconductor (-40%) also hurt. Lattice Semiconductor was not held at period end. &lt;span&gt;&#160;&lt;/span&gt;&lt;span&gt;&#160;&lt;/span&gt;&lt;/span&gt;&lt;/li&gt;&lt;li style="margin:5px 0px 2px 24px;padding:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;Notable changes in positioning include higher allocations to communication services and financials.&lt;/span&gt;&lt;/li&gt;&lt;/ul&gt;

This move, approved by the Board of Trustees in June 2023, was deemed in the best interest of shareholders. The new ETF and its former corresponding fund have identical investment objectives and fundamental investment policies and have substantially similar investment strategies. Returns prior to the conversion are those of the former corresponding fund. Fidelity believes that the conversion will provide multiple benefits for investors of the fund, including lower net expenses, additional trading flexibility, increased portfolio holdings transparency and the potential for enhanced tax efficiency. Effective March 1, 2024, the fund's fiscal year end changed from August 31 to June 30.&lt;/span&gt;&lt;/div&gt;

Amid this favorable backdrop for higher-risk assets, stocks continued their late-2023 momentum, powered by signs of continued U.S. economic strength.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-indent:-24px;margin-bottom:2px;margin-left:45px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;Against this backdrop, the United States gained 27% and contributed most from a security selection standpoint, followed by the U.K. (+8%). By sector, picks among information technology (+26%) stocks helped most. Exposure to the real estate (+16%) category proved advantageous as well.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-indent:-24px;margin-bottom:2px;margin-left:45px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;Conversely, emerging markets returned -44% and detracted most, followed by Canada (-6%). As it relates to sectors, industrials generated an approximately -28% result and hurt most.&#160;&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-indent:-24px;margin-bottom:2px;margin-left:45px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;Turning to individual stocks, the biggest contributor was technology hardware &amp;amp; equipment company Super Micro Computer (+243%). A stake in Western Digital (+100%) - another technology hardware &amp;amp; equipment stock - was a plus as well. MicroStrategy (+340%), Microsoft (+36%) and ServiceNow (+40%), within the software &amp;amp; services industry, further lifted the fund's performance.&#160;&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-indent:-24px;margin-bottom:2px;margin-left:45px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;Conversely, the biggest individual detractor was software &amp;amp; services firm MongoDB (-39%). Other software &amp;amp; services holdings, including Five9 (-46%), Snowflake (-23%), Fastly (-53%) and Teradata (-35%), proved detrimental as well.&lt;/span&gt;&lt;/div&gt;

Amid this favorable backdrop for higher-risk assets, stocks continued their late-2023 momentum, powered by signs of continued U.S. economic strength.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-indent:-24px;margin-bottom:2px;margin-left:45px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;Against this backdrop, the United States returned -24% and detracted most from a security selection standpoint, followed by emerging markets (-41%). By sector, consumer discretionary stocks generated a -31% result and hurt most. Specifically, this group was hampered by the automobiles &amp;amp; components industry (-34%). Elsewhere, industrials (-37%) firms also were challenged, particularly the capital goods industry (-46%). Other notable detractors were the materials (-63%) and information technology (-14%) sectors.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-indent:-24px;margin-bottom:2px;margin-left:45px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;Turning to individual stocks, the biggest detractor was materials stock Albemarle (-57%). In capital goods, stakes in Plug Power (-78%) and ChargePoint Holdings (-83%) hurt as well. Samsung SDI (-49%), a technology hardware &amp;amp; equipment company, further detracted. Lastly, NIO (-57%), within the automobiles &amp;amp; components group, also proved detrimental to performance.&#160;&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-indent:-24px;margin-bottom:2px;margin-left:45px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;Conversely, the top individual contributor was semiconductors &amp;amp; semiconductor equipment stock Analog Devices (+31%). Elsewhere in the industry, NXP Semiconductors (+34%) was another plus. In the consumer durables &amp;amp; apparel category, Garmin advanced roughly 37% and aided performance. Capital goods company Blue Bird rose 139% and helped as well. Lastly, Lyft (+46%), from the transportation category, was another plus.&lt;/span&gt;&lt;/div&gt;

Amid this favorable backdrop for higher-risk assets, stocks continued their late-2023 momentum, powered by signs of continued U.S. economic strength.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-indent:-24px;margin-bottom:2px;margin-left:45px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;Against this backdrop, the United States returned -43% and was the foremost detractor this period from a security selection standpoint, followed by emerging markets (-30%). By sector, information technology generated a roughly -49% result and hurt performance most. This group was hampered by the semiconductors &amp;amp; semiconductor equipment industry (-53%) in particular. Industrials (-35%) stocks also were challenged, hindered by the capital goods industry (-36%). Other notable detractors were the utilities (-13%) and the energy (-88%) sectors.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-indent:-24px;margin-bottom:2px;margin-left:45px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;Turning to individual stocks, the biggest detractor was SolarEdge Technologies (-82%), within the semiconductors &amp;amp; semiconductor equipment category. Enphase Energy (-41%) - another semiconductors &amp;amp; semiconductor equipment firm - also proved detrimental in terms of the portfolio's result. Plug Power (-77%) and Shoals Technologies (-76%), within the capital goods industry, hindered the fund's return as well. Additionally, utilities stock &#xd8;rsted (-44%) further pressured performance.&#160;&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-indent:-24px;margin-bottom:2px;margin-left:45px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;In contrast, the biggest individual contributor was First Solar (+18%), within the semiconductors &amp;amp; semiconductor equipment industry. Among utilities holdings, Neoen (+29%) and Meridian Energy (+15%) aided performance. Cadeler (+42%), a stock in the capital goods group, was another plus. Lastly, in technology hardware &amp;amp; equipment, Itron gained 14% and lifted the fund as well.&lt;/span&gt;&lt;/div&gt;

Amid this favorable backdrop for higher-risk assets, stocks continued their late-2023 momentum, powered by signs of continued U.S. economic strength.&lt;/span&gt;&lt;/div&gt;

By sector, health care stocks produced a -6% result and were most detrimental to performance. Specifically, this group was hampered by the health care equipment &amp;amp; services industry (-6%). Elsewhere, exposure to consumer staples (-18%) and communication services (0%) companies further detracted.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-indent:-24px;margin-bottom:2px;margin-left:45px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;In contrast, Asia Pacific ex Japan gained 56% and contributed most, followed by Europe ex the U.K. (+24%), especially Sweden (+13%). In terms of sectors, information technology returned -1% and contributed most, driven by the software &amp;amp; services industry (+7%). Stakes in industrials stocks also helped (+3%).&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-indent:-24px;margin-bottom:2px;margin-left:45px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;On an individual basis, the biggest detractor was health care equipment &amp;amp; services firm Inspire Medical Systems (-59%). Teladoc Health (-61%), Nevro (-67%) and Accolade (-71%) - all health care equipment &amp;amp; services holdings as well - further challenged performance. Among consumer staples distribution &amp;amp; retail stocks, JD Health International returned about -53% and further weighed on performance.&#160;&lt;/span&gt;&lt;/div&gt;

Elsewhere in the health care equipment &amp;amp; services industry, stakes in Hims &amp;amp; Hers Health (+107%), Cochlear (+48%), Intuitive Surgical (+30%) and Tandem Diabetes Care (+66%) also helped.&lt;/span&gt;&lt;/div&gt;

Amid this favorable backdrop for higher-risk assets, stocks continued their late-2023 momentum, powered by signs of continued U.S. economic strength. &lt;/span&gt;&lt;/li&gt;&lt;li style="margin:5px 0px 2px 24px;padding:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;Against this backdrop, security selection was the primary contributor to the fund's performance versus the benchmark, especially within information technology. Stock selection in consumer discretionary, stock picks and an underweight in consumer staples, and picks and an overweight in communication services also boosted the fund's relative performance. &lt;span&gt;&#160;&lt;/span&gt;&lt;/span&gt;&lt;/li&gt;&lt;li style="margin:5px 0px 2px 24px;padding:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;The top individual relative contributor was an overweight in Nvidia (+190%), which was the fund's largest holding at period end. An underweight in Tesla (-24%) and an overweight in Broadcom (+87%) also contributed. Broadcom was among the fund's biggest holdings. &lt;span&gt;&#160;&lt;/span&gt;&lt;/span&gt;&lt;/li&gt;&lt;li style="margin:5px 0px 2px 24px;padding:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;In contrast, the biggest detractor from performance versus the benchmark was stock picking in health care, primarily within the pharmaceuticals, biotechnology &amp;amp; life sciences industry. Also hurting our result were security selection and an overweight in industrials, primarily within the capital goods industry, and stock picks and an underweight in energy. &lt;span&gt;&#160;&lt;/span&gt;&lt;/span&gt;&lt;/li&gt;&lt;li style="margin:5px 0px 2px 24px;padding:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;The biggest individual relative detractor was our non-benchmark stake in Teradata (-36%). This period we increased our investment in the stock. Other notable relative detractors included an underweight in Eli Lilly (+94%) and a non-benchmark stake in Hawaiian Electric Industries (-54%). Hawaiian Electric was not held at period end. &lt;span&gt;&#160;&lt;/span&gt;&lt;/span&gt;&lt;/li&gt;&lt;li style="margin:5px 0px 2px 24px;padding:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;Notable changes in positioning include increased exposure to communication services and a lower allocation to consumer discretionary. &lt;/span&gt;&lt;/li&gt;&lt;/ul&gt;

This move, approved by the Board of Trustees in June 2023, was deemed in the best interest of shareholders. The new ETF and its former corresponding fund have identical investment objectives and fundamental investment policies and have substantially similar investment strategies. Returns prior to the conversion are those of the former corresponding fund. Fidelity believes that the conversion will provide multiple benefits for investors of the fund, including lower net expenses, additional trading flexibility, increased portfolio holdings transparency and the potential for enhanced tax efficiency. Effective March 1, 2024, the fund's fiscal year end changed from August 31 to June 30.&lt;/span&gt;&lt;/div&gt;

Amid this favorable backdrop for higher-risk assets, stocks continued their late-2023 momentum, powered by signs of continued U.S. economic strength.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-indent:-24px;margin-bottom:2px;margin-left:45px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;Against this backdrop, the United States gained roughly 78% and contributed most from a security selection standpoint, followed by Asia Pacific ex Japan (+91%), especially Singapore (+29%). By sector, information technology stocks rose about 52% and helped most, driven by the software &amp;amp; services industry (+60%). Exposure to financials stocks (+52%) proved advantageous as well.&#160;&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-indent:-24px;margin-bottom:2px;margin-left:45px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;Conversely, Europe ex the U.K. returned -43% and detracted most, followed by emerging markets (-22%), especially Brazil (+6%). As it relates to sectors, communication services firms returned about -27% and were the biggest challenge.&#160;&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-indent:-24px;margin-bottom:2px;margin-left:45px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;In terms of individual holdings, the biggest contributor was financial services stock Coinbase Global (+208%). Elsewhere, CleanSpark (+265%), TeraWulf (+154%), Core Scientific (+171%) and Iris Energy (+145%), within the software &amp;amp; services industry, also stood out to the upside.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-indent:-24px;margin-bottom:2px;margin-left:45px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;In contrast, the biggest individual detractor was Riot Platforms (-23%), a software &amp;amp; services company. Exposure to another software &amp;amp; services stock, Hive Digital Technologies (-33%), hurt as well. Among technology hardware &amp;amp; equipment firms, Canaan returned approximately -47% and further detracted, as did financial services positions Worldline (-71%) and Flywire (-47%).&lt;/span&gt;&lt;/div&gt;

Amid this favorable backdrop for higher-risk assets, stocks continued their late-2023 momentum, powered by signs of continued U.S. economic strength.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-indent:-24px;margin-bottom:2px;margin-left:45px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;Against this backdrop, the United States gained approximately 34% and was a notable contributor in terms of security selection. By sector, information technology stocks rose about 22% and added the most value. Exposure to communication services (+18%) firms also helped. Elsewhere, the real estate sector was up about 17%, boosted by real estate investment trusts (+24%) in particular.&#160;&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-indent:-24px;margin-bottom:2px;margin-left:45px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;Conversely, equity markets in Europe ex the U.K., especially Switzerland (-68%), returned -27% and detracted most, followed by the U.K. (-44%). From a sector standpoint, consumer discretionary firms returned -20% and were the biggest performance challenge.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-indent:-24px;margin-bottom:2px;margin-left:45px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;Turning to individual stocks, the top contributor was semiconductors &amp;amp; semiconductor equipment company Nvidia (+199%). A stake in Qualcomm (+81%), another position within the semiconductors &amp;amp; semiconductor equipment industry, helped as well. Among technology hardware &amp;amp; equipment firms, Super Micro Computer gained roughly 244% and further boosted the fund's performance. Stakes in Meta Platforms (+74%) and Alphabet (+52%), within the media &amp;amp; entertainment category, proved advantageous as well.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-indent:-24px;margin-bottom:2px;margin-left:45px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;In contrast, the biggest individual detractor was semiconductors &amp;amp; semiconductor equipment stock Intel (-32%). ams ORSAM (-68%) and Advanced Micro Devices (-15%), also in the semiconductors &amp;amp; semiconductor equipment industry, further pressured the portfolio's return. Exposure to software &amp;amp; services company Unity Software (-61%) hurt as well. Lastly, another notable detractor was NCSoft (-41%), a media &amp;amp; entertainment holding.&lt;/span&gt;&lt;/div&gt;
