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 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 (including one year of capped expenses in each period) remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example - DWS Small Cap Core Fund - USD ($)	Class A	Class T	Class C	Class R6	INST Class	Class S
1 Year	$ 680	$ 358	$ 287	$ 81	$ 86	$ 91
3 Years	932	609	610	272	294	312
5 Years	1,203	879	1,059	479	519	551
10 Years	$ 1,976	$ 1,648	$ 2,305	$ 1,076	$ 1,167	$ 1,236

You would pay the following expenses if you did not redeem your shares:

Expense Example, No Redemption - DWS Small Cap Core Fund - USD ($)	Class A	Class T	Class C	Class R6	INST Class	Class S
1 Year	$ 680	$ 358	$ 187	$ 81	$ 86	$ 91
3 Years	932	609	610	272	294	312
5 Years	1,203	879	1,059	479	519	551
10 Years	$ 1,976	$ 1,648	$ 2,305	$ 1,076	$ 1,167	$ 1,236

<p>PORTFOLIO TURNOVER </p>

The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs and may mean higher taxes if you are investing in a taxable account. These costs are not reflected in annual fund operating expenses or in the expense example, and can affect the fund's performance. During the most recent fiscal year, the fund's portfolio turnover rate was 44% of the average value of its portfolio.

<p>Principal Investment Strategy</p>

Main investments. Under normal circumstances, the fund invests at least 80% of net assets, plus the amount of any borrowings for investment purposes, in common stocks of small US companies with potential for above-average long-term total return. These companies are similar in size to the companies in the Russell 2000® Index (generally the 2,000 smallest companies out of the 3,000 largest companies in the US). While the market capitalization range of the Russell 2000® Index changes throughout the year, as of December 31, 2018, the market capitalization range of the Russell 2000® Index was between $7.9 million and $6.2 billion. The Russell 2000® Index is reconstituted annually every June. 

The fund intends to invest in companies whose market capitalizations fall within the normal range of the Russell 2000® Index. While the fund invests primarily in common stocks, it may invest up to 20% of its total assets in US government securities. While the fund invests mainly in US stocks, it may invest up to 20% of net assets in foreign securities.

Management process. Portfolio management uses an active process that combines financial analysis with an assessment of corporate strategy and management quality. Portfolio management focuses on stocks that they believe are undervalued relative to their intrinsic worth. Portfolio management considers various fundamental factors including, but not limited to, free cash flow yield and return on invested capital in seeking to identify undervalued securities.

Portfolio management generally seeks companies that it believes have high returns on invested capital, strong corporate governance practices and conservative accounting. Portfolio management prefers companies that demonstrate sustainable and growing cash flows. The fund's portfolio is assembled on a stock-by-stock basis and sector weights are not predetermined by a benchmark.

Portfolio management will normally sell a stock when its price reaches portfolio management's expectations or portfolio management believes there has been a deterioration in the company's fundamental value. A stock may also be sold when portfolio management believes that other investments offer better opportunities.

Securities lending. The fund may lend securities (up to one-third of total assets) to approved institutions, such as registered broker-dealers, banks and pooled investment vehicles.

<p>Main Risks</p>

There are several risk factors that could hurt the fund's performance, cause you to lose money or cause the fund's performance to trail that of other investments. The fund may not achieve its investment objective, and is not intended to be a complete investment program. An investment in the fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency.

Stock market risk. When stock prices fall, you should expect the value of your investment to fall as well. Stock prices can be hurt by poor management on the part of the stock's issuer, shrinking product demand and other business risks. These may affect single companies as well as groups of companies. The market as a whole may not favor the types of investments the fund makes, which could adversely affect a stock's price, regardless of how well the company performs, or the fund's ability to sell a stock at an attractive price. There is a chance that stock prices overall will decline because stock markets tend to move in cycles, with periods of rising and falling prices. Events in the US and global financial markets, including actions taken by the US Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility which could negatively affect performance. Further, geopolitical and other events, including war, terrorism, economic uncertainty, trade disputes and related geopolitical events have led, and in the future may lead, to increased short-term market volatility, which may disrupt securities markets and have adverse long-term effects on US and world economies and markets. To the extent the fund invests in a particular capitalization or sector, the fund's performance may be affected by the general performance of that particular capitalization or sector.

Small company risk. Small company stocks tend to be more volatile than medium-sized or large company stocks. Because stock analysts are less likely to follow small companies, less information about them is available to investors. Industry-wide reversals may have a greater impact on small companies, since they may lack the financial resources of larger companies. Small company stocks are typically less liquid than large company stocks.

Security selection risk. The securities in the fund's portfolio may decline in value. Portfolio management could be wrong in its analysis of industries, companies, economic trends, the relative attractiveness of different securities or other matters.

Focus risk. To the extent that the fund focuses its investments in particular industries, asset classes or sectors of the economy, any market price movements, regulatory or technological changes, or economic conditions affecting companies in those industries, asset classes or sectors may have a significant impact on the fund's performance.

Foreign investment risk. The fund faces the risks inherent in foreign investing. Adverse political, economic or social developments could undermine the value of the fund's investments or prevent the fund from realizing the full value of its investments. In June 2016, citizens of the United Kingdom approved a referendum to leave the European Union (EU) and in March 2017, the United Kingdom initiated its withdrawal from the EU, which is expected to take place by March 2019. Significant uncertainty exists regarding the United Kingdom's anticipated withdrawal from the EU and any adverse economic and political effects such withdrawal may have on the United Kingdom, other EU countries and the global economy.

Financial reporting standards for companies based in foreign markets differ from those in the US. Additionally, foreign securities markets generally are smaller and less liquid than US markets. To the extent that the fund invests in non-US dollar denominated foreign securities, changes in currency exchange rates may affect the US dollar value of foreign securities or the income or gain received on these securities.

Securities lending risk. Any decline in the value of a portfolio security that occurs while the security is out on loan is borne by the fund and will adversely affect performance. Also, there may be delays in recovery of securities loaned or even a loss of rights in the collateral should the borrower of the securities fail financially while holding the security.

Counterparty risk. A financial institution or other counterparty with whom the fund does business, or that underwrites, distributes or guarantees any investments or contracts that the fund owns or is otherwise exposed to, may decline in financial health and become unable to honor its commitments. This could cause losses for the fund or could delay the return or delivery of collateral or other assets to the fund.

Liquidity risk. In certain situations, it may be difficult or impossible to sell an investment and/or the fund may sell certain investments at a price or time that is not advantageous in order to meet redemption requests or other cash needs. Unusual market conditions, such as an unusually high volume of redemptions or other similar conditions could increase liquidity risk for the fund.

Pricing risk. If market conditions make it difficult to value some investments, the fund may value these investments using more subjective methods, such as fair value pricing. In such cases, the value determined for an investment could be different from the value realized upon such investment's sale. As a result, you could pay more than the market value when buying fund shares or receive less than the market value when selling fund shares.

Operational and technology risk. Cyber-attacks, disruptions, or failures that affect the fund's service providers or counterparties, issuers of securities held by the fund, or other market participants may adversely affect the fund and its shareholders, including by causing losses for the fund or impairing fund operations.

<p>Past Performance</p>

How a fund's returns vary from year to year can give an idea of its risk; so can comparing fund performance to overall market performance (as measured by an appropriate market index). Past performance may not indicate future results. All performance figures below assume that dividends and distributions were reinvested. For more recent performance figures, go to dws.com (the Web site does not form a part of this prospectus) or call the phone number included in this prospectus.

The performance figures for Class T shares prior to class inception are based on the historical performance of the fund's Class S shares adjusted to reflect the higher expenses and applicable sales charges of Class T.

Prior to May 31, 2013, the fund had a sub-advisor and a different investment management team that operated with a different investment strategy. Performance would have been different if the fund's current investment strategy had been in effect.
