But momentum faded in late February, as conflict in the Middle East took center stage.&lt;/span&gt;&lt;/div&gt;

Also hurting our result were stock picks in industrials and communication services, primarily within the media &amp;amp; entertainment industry.&lt;/span&gt;&lt;/div&gt;

A second notable relative detractor was our stake in Arthur J Gallagher (-41%). The stock was not held at period end. A non-benchmark stake in Constellation Software returned about -34% and notably hurt. The stock was not held at period end.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right: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;In contrast, the biggest contributor to performance versus the benchmark was an underweight in health care. Stock picks and an overweight in information technology, primarily within the semiconductors &amp;amp; semiconductor equipment industry, also boosted the fund's relative performance. Also contributing to our result was an underweight in consumer staples, primarily within the household &amp;amp; personal products industry.&lt;/span&gt;&lt;/div&gt;

This period we decreased our stake in the stock. A second notable relative contributor was an overweight in Amphenol (+94%). This period we decreased our stake in the company, though it was one of the fund's biggest holdings this period. Another notable relative contributor was our non-benchmark stake in Taiwan Semiconductor Manufacturing (+99%), one of our biggest holdings at period end.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right: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;Notable changes in positioning include decreased exposure to the communication services and materials sectors.&lt;/span&gt;&lt;/div&gt;

But momentum faded in late February, as conflict in the Middle East took center stage.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right: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;Against this backdrop, security selection was the primary detractor from the fund's performance versus the S&amp;amp;P 500&#xae; index for the fiscal year, especially within financials. Also hurting our result was stock picking in industrials and communication services, primarily within the media &amp;amp; entertainment industry.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right: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;The largest individual relative detractor was an underweight in Alphabet (+86%), which was not in the portfolio on March 31. A second notable relative detractor was our stake in Arthur J Gallagher (-41%). The stock was not held at period end. A non-benchmark stake in Constellation Software returned -34% and notably hurt. The stock was not held at period end.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right: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;In contrast, the biggest contributor to performance versus the benchmark was an underweight in health care. Security selection and an overweight in information technology, primarily within the semiconductors &amp;amp; semiconductor equipment industry, also boosted relative performance. Also helping our relative result was an underweight in consumer staples, primarily within the household &amp;amp; personal products industry.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right: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;The top individual relative contributor was an overweight in Quanta Services (+117%), where we decreased our investment this period. The second-largest relative contributor was an overweight in Amphenol (+94%). This period we reduced our investment in the company, though it was among the fund's biggest holdings this period. Another notable relative contributor was our non-benchmark stake in Taiwan Semiconductor Manufacturing (+99%), one of our largest holdings at period end.&lt;/span&gt;&lt;/div&gt;

But momentum faded in late February, as conflict in the Middle East took center stage.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right: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;Against this backdrop, security selection was the primary detractor from the fund's performance versus the S&amp;amp;P 500&#xae; index for the fiscal year, especially within financials. Also hurting our result was stock picking in industrials and communication services, primarily within the media &amp;amp; entertainment industry.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right: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;The largest individual relative detractor was an underweight in Alphabet (+86%), which was not in the portfolio on March 31. A second notable relative detractor was our stake in Arthur J Gallagher (-41%). The stock was not held at period end. A non-benchmark stake in Constellation Software returned -34% and notably hurt. The stock was not held at period end.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right: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;In contrast, the biggest contributor to performance versus the benchmark was an underweight in health care. Security selection and an overweight in information technology, primarily within the semiconductors &amp;amp; semiconductor equipment industry, also boosted relative performance. Also helping our relative result was an underweight in consumer staples, primarily within the household &amp;amp; personal products industry.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right: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;The top individual relative contributor was an overweight in Quanta Services (+117%), where we decreased our investment this period. The second-largest relative contributor was an overweight in Amphenol (+94%). This period we reduced our investment in the company, though it was among the fund's biggest holdings this period. Another notable relative contributor was our non-benchmark stake in Taiwan Semiconductor Manufacturing (+99%), one of our largest holdings at period end.&lt;/span&gt;&lt;/div&gt;

But momentum faded in late February, as conflict in the Middle East took center stage.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right: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;Against this backdrop, security selection was the primary detractor from the fund's performance versus the S&amp;amp;P 500&#xae; index for the fiscal year, especially within financials. Also hurting our result was stock picking in industrials and communication services, primarily within the media &amp;amp; entertainment industry.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right: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;The largest individual relative detractor was an underweight in Alphabet (+86%), which was not in the portfolio on March 31. A second notable relative detractor was our stake in Arthur J Gallagher (-41%). The stock was not held at period end. A non-benchmark stake in Constellation Software returned -34% and notably hurt. The stock was not held at period end.&lt;/span&gt;&lt;/div&gt;

Security selection and an overweight in information technology, primarily within the semiconductors &amp;amp; semiconductor equipment industry, also boosted relative performance. Also helping our relative result was an underweight in consumer staples, primarily within the household &amp;amp; personal products industry.&lt;/span&gt;&lt;/div&gt;

The second-largest relative contributor was an overweight in Amphenol (+94%). This period we reduced our investment in the company, though it was among the fund's biggest holdings this period. Another notable relative contributor was our non-benchmark stake in Taiwan Semiconductor Manufacturing (+99%), one of our largest holdings at period end.&lt;/span&gt;&lt;/div&gt;

But momentum faded in late February, as conflict in the Middle East took center stage.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right: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;Against this backdrop, security selection was the primary detractor from the fund's performance versus the S&amp;amp;P 500&#xae; index for the fiscal year, especially within financials. Also hurting our result was stock picking in industrials and communication services, primarily within the media &amp;amp; entertainment industry.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right: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;The largest individual relative detractor was an underweight in Alphabet (+86%), which was not in the portfolio on March 31. A second notable relative detractor was our stake in Arthur J Gallagher (-41%). The stock was not held at period end. A non-benchmark stake in Constellation Software returned -34% and notably hurt. The stock was not held at period end.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right: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;In contrast, the biggest contributor to performance versus the benchmark was an underweight in health care. Security selection and an overweight in information technology, primarily within the semiconductors &amp;amp; semiconductor equipment industry, also boosted relative performance. Also helping our relative result was an underweight in consumer staples, primarily within the household &amp;amp; personal products industry.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right: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;The top individual relative contributor was an overweight in Quanta Services (+117%), where we decreased our investment this period. The second-largest relative contributor was an overweight in Amphenol (+94%). This period we reduced our investment in the company, though it was among the fund's biggest holdings this period. Another notable relative contributor was our non-benchmark stake in Taiwan Semiconductor Manufacturing (+99%), one of our largest holdings at period end.&lt;/span&gt;&lt;/div&gt;

But momentum faded in late February, as conflict in the Middle East took center stage.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right: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;Against this backdrop, security selection was the primary detractor from the fund's performance versus the S&amp;amp;P 500&#xae; index for the fiscal year, especially within financials. Also hurting our result was stock picking in industrials and communication services, primarily within the media &amp;amp; entertainment industry.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right: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;The largest individual relative detractor was an underweight in Alphabet (+86%), which was not in the portfolio on March 31. A second notable relative detractor was our stake in Arthur J Gallagher (-41%). The stock was not held at period end. A non-benchmark stake in Constellation Software returned -34% and notably hurt. The stock was not held at period end.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right: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;In contrast, the biggest contributor to performance versus the benchmark was an underweight in health care. Security selection and an overweight in information technology, primarily within the semiconductors &amp;amp; semiconductor equipment industry, also boosted relative performance. Also helping our relative result was an underweight in consumer staples, primarily within the household &amp;amp; personal products industry.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right: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;The top individual relative contributor was an overweight in Quanta Services (+117%), where we decreased our investment this period. The second-largest relative contributor was an overweight in Amphenol (+94%). This period we reduced our investment in the company, though it was among the fund's biggest holdings this period. Another notable relative contributor was our non-benchmark stake in Taiwan Semiconductor Manufacturing (+99%), one of our largest holdings at period end.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right: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;Notable changes in positioning include lower allocations to the communication services and materials sectors.&lt;/span&gt;&lt;/div&gt;

But momentum faded in late February, as conflict in the Middle East took center stage.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right: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;Against this backdrop, security selection was the primary detractor from the fund's performance versus the S&amp;amp;P 500&#xae; index for the fiscal year, especially within financials. Also hurting our result was stock picking in industrials and communication services, primarily within the media &amp;amp; entertainment industry.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right: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;The largest individual relative detractor was an underweight in Alphabet (+86%), which was not in the portfolio on March 31. A second notable relative detractor was our stake in Arthur J Gallagher (-41%). The stock was not held at period end. A non-benchmark stake in Constellation Software returned -34% and notably hurt. The stock was not held at period end.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right: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;In contrast, the biggest contributor to performance versus the benchmark was an underweight in health care. Security selection and an overweight in information technology, primarily within the semiconductors &amp;amp; semiconductor equipment industry, also boosted relative performance. Also helping our relative result was an underweight in consumer staples, primarily within the household &amp;amp; personal products industry.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right: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;The top individual relative contributor was an overweight in Quanta Services (+117%), where we decreased our investment this period. The second-largest relative contributor was an overweight in Amphenol (+94%). This period we reduced our investment in the company, though it was among the fund's biggest holdings this period. Another notable relative contributor was our non-benchmark stake in Taiwan Semiconductor Manufacturing (+99%), one of our largest holdings at period end.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right: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;Notable changes in positioning include lower allocations to the communication services and materials sectors.&lt;/span&gt;&lt;/div&gt;

But momentum faded in late February, as conflict in the Middle East took center stage.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right: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;Against this backdrop, security selection was the primary detractor from the fund's performance versus the S&amp;amp;P 500&#xae; index for the fiscal year, especially within financials. Also hurting our result was stock picking in industrials and communication services, primarily within the media &amp;amp; entertainment industry.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right: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;The largest individual relative detractor was an underweight in Alphabet (+86%), which was not in the portfolio on March 31. A second notable relative detractor was our stake in Arthur J Gallagher (-41%). The stock was not held at period end. A non-benchmark stake in Constellation Software returned -34% and notably hurt. The stock was not held at period end.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right: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;In contrast, the biggest contributor to performance versus the benchmark was an underweight in health care. Security selection and an overweight in information technology, primarily within the semiconductors &amp;amp; semiconductor equipment industry, also boosted relative performance. Also helping our relative result was an underweight in consumer staples, primarily within the household &amp;amp; personal products industry.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right: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;The top individual relative contributor was an overweight in Quanta Services (+117%), where we decreased our investment this period. The second-largest relative contributor was an overweight in Amphenol (+94%). This period we reduced our investment in the company, though it was among the fund's biggest holdings this period. Another notable relative contributor was our non-benchmark stake in Taiwan Semiconductor Manufacturing (+99%), one of our largest holdings at period end.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right: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;Notable changes in positioning include lower allocations to the communication services and materials sectors.&lt;/span&gt;&lt;/div&gt;
