⁽¹⁾Touchstone Advisors, Inc. (the "Advisor" or "Touchstone Advisors") and Touchstone Strategic Trust (the “Trust”) have entered into a contractual expense limitation agreement whereby Touchstone Advisors will waive a portion of its fees or reimburse certain Fund expenses (excluding dividend and interest expenses relating to short sales; interest; taxes; brokerage commissions and other transaction costs; portfolio transactions and investment related expenses; other expenditures which are capitalized in accordance with U.S. generally accepted accounting principles; the cost of “Acquired Fund Fees and Expenses,” if any; and other extraordinary expenses not incurred in the ordinary course of business) in order to limit annual Fund operating expenses to 1.08%, 1.83%, 0.83%, and 0.68% of average daily net assets for Classes A, C, Y, and Institutional Class shares, respectively. This contractual expense limitation is effective through October 29, 2017, but can be terminated by a vote of the Board of Trustees of the Trust (the “Board”) if it deems the termination to be beneficial to the Fund’s shareholders. The terms of the contractual expense limitation agreement provide that Touchstone Advisors is entitled to recoup, subject to approval by the Board, such amounts waived or reimbursed for a period of up to three years from the year in which Touchstone Advisors reduced its compensation or assumed

Example. This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then, except as indicated, redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same and that all fee waivers or expense limits for the Fund will expire after one year. Although your actual costs may be higher or lower, based on these assumptions your costs would be:



	Assuming Redemption at End of Period								Assuming No Redemption
	Class A		Class C		Class Y		Institutional Class		Class C
1 Year	$	679	$	286	$	85	$	69	$	186
3 Years	$	939	$	644	$	299	$	259	$	644
5 Years	$	1,219	$	1,129	$	532	$	464	$	1,129
10 Years	$	2,015	$	2,467	$	1,198	$	1,055	$	2,467

Portfolio Turnover. The Fund pays transaction costs, such as brokerage commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the portfolio turnover rate was 19% of the average value of its portfolio.

The Fund normally invests in equity securities of large- and mid-cap companies (generally, companies with market capitalizations of approximately $2.5 billion or higher) that the Fund’s sub-advisor, Barrow, Hanley, Mewhinney & Strauss, LLC (“Barrow Hanley”) believes are undervalued. As part of this strategy, the Fund may invest up to 15% of its assets in foreign equity securities. Equity securities include common and preferred stocks and depositary receipts. Barrow Hanley uses traditional methods of stock selection — research and analysis — to identify securities it believes are undervalued and searches for companies that have price to earnings and price to book ratios below the market and that have above average dividend yields.

Although the Fund may also focus its investments within certain sectors, Barrow Hanley uses risk management tools to prevent over-exposure to particular market segments. Barrow Hanley is a “bottom-up” value manager meaning it analyzes the fundamentals of companies one at a time rather than focusing on broader market themes.

Barrow Hanley generally considers selling a security when it reaches fair value estimate, when earnings forecasts do not appear to justify the current price, when there has been or there is an expectation of an adverse change in the company’s fundamentals, or when other investment opportunities appear more attractive.

Equity Securities Risk: The Fund is subject to the risk that stock prices will fall over short or extended periods of time. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by these companies may decline in response to such developments, which could result in a decline in the value of the Fund’s shares.

Foreign Securities Risk: Investing in foreign securities poses additional risks since political and economic events unique in a country or region will affect those markets and their issuers, while such events may not necessarily affect the U.S. economy or issuers located in the United States. In addition, investments in foreign securities are generally denominated in foreign currency. As a result, changes in the value of those currencies compared to the U.S. dollar may affect (positively or negatively) the value of the Fund's investments. Foreign markets may be less liquid and more volatile than U.S. markets and offer less protection to investors.

Management Risk: In managing the Fund’s portfolio, the Advisor engages one or more sub-advisors to make investment decisions for a portion of or the entire portfolio. There is a risk that the Advisor may be unable to identify and retain sub-advisors who achieve superior investment returns relative to other similar sub-advisors.

Sector Focus Risk: The Fund may invest a high percentage of its assets in specific sectors of the market in order to achieve a potentially greater investment return. As a result, the Fund may be more susceptible to economic, political, and regulatory developments in a particular sector of the market, positive or negative than a fund that does not invest a high percentage of its assets in specific sectors.

Value Investing Risk: Value investing presents the risk that the Fund’s security holdings may never reach their full market value because the market fails to recognize what the portfolio managers consider the true business value or because the portfolio managers have misjudged those values.

The bar chart and performance table below illustrate the risks and volatility of an investment in the Fund by showing changes in the Fund’s performance from calendar year to calendar year and by showing how the Fund’s average annual total returns for one year, five years, and ten years compare with the Russell 1000^® Value Index. The bar chart does not reflect any sales charges, which would reduce your return. Past performance (before and after taxes) does not necessarily indicate how the Fund will perform in the future.

⁽¹⁾Before the Fund commenced operations, all of the assets and liabilities of the Old Mutual Barrow Hanley Value Fund (the “Predecessor Fund”) were transferred to the Fund in a tax-free reorganization (the “Reorganization”). The Reorganization occurred on April 16, 2012. As a result of the Reorganization, the Fund assumed the performance and accounting history of the Predecessor Fund prior to the date of the Reorganization. For more information on the prior history of the Fund, please see the section entitled “The Trust” in the Fund’s SAI.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Your after-tax returns may differ from those shown and depend on your tax situation. The after-tax returns do not apply to shares held in an IRA, 401(k), or other tax-advantaged account. After-tax returns are only shown for Class A shares and after-tax returns for other classes will vary.

The inception dates of Class A shares, Class C shares, Class Y shares, and Institutional Class shares were: July 31, 2003, April 12, 2012, September 10, 1998, and December 20, 2006, respectively. Class C and Institutional Class shares’ performance was calculated using the historical performance of Class Y shares for the periods prior to April 12, 2012 and December 20, 2006, respectively. Performance for these periods has been restated to reflect the impact of the fees and expenses applicable to Class C and Institutional Class shares.

(“Touchstone Securities”) or through your financial intermediary. Class Y shares are available only through financial intermediaries who have appropriate selling agreements in place with Touchstone Securities. Institutional Class shares are available through Touchstone Securities or your financial intermediary. Shares may be purchased or sold by writing to Touchstone Securities at P.O. Box 9878, Providence, Rhode Island 02940, calling 1.800.543.0407, or visiting the Touchstone Funds’ website: TouchstoneInvestments.com.

If your shares are held by a processing organization or financial intermediary you will need to follow its purchase and redemption procedures.

If you purchase shares in the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund and its related companies may pay the intermediary for the sale of Fund shares and related services.

Ask your salesperson or visit your financial intermediary’s website for more information.


•	Large-Cap Risk: Large-cap companies may be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes, and also may not be able to attain the high growth rate of successful smaller companies, especially during extended periods of economic expansion.


•	Mid-Cap Risk: Stocks of mid-sized companies may be subject to more abrupt or erratic market movements than stocks of larger, more established companies. Mid-sized companies may have limited product lines, or financial resources, and may be dependent upon a particular niche of the market.


•	Preferred Stock Risk: In the event an issuer is liquidated or declares bankruptcy, the claims of owners of bonds take precedence over the claims of those who own preferred and common stock. If interest rates rise, the fixed dividend on preferred stocks may be less attractive, causing the price of preferred stocks to decline.


•	Depositary Receipts Risk: Foreign receipts, which include American Depositary Receipts, Global Depositary Receipts, and European Depositary Receipts, are securities that evidence ownership interests in a security or a pool of securities issued by a foreign issuer. The risks of depositary receipts include many risks associated with investing directly in foreign securities.
