SUPPLEMENT TO THE CURRENTLY EFFECTIVE SUMMARY PROSPECTUS

DWS Global Macro Fund

Class R6

Effective on or about October 1, 2019, the prospectus is supplemented as follows:

The following replaces the first paragraph contained under “Main investments” in the “PRINCIPAL INVESTMENT STRATEGY” section of the fund’s summary prospectus:

Main investments. The fund invests in equities (common and preferred), bonds, structured notes, money market instruments, exchange-traded funds (ETFs), and cash. There are generally no limits on asset class exposures, provided that risk parameters are met. The fund may also invest in alternative asset classes (such as real estate, REITs, infrastructure, convertibles, commodities and currencies). The fund may achieve exposure to commodities by investing in commodities-linked derivatives. In addition, the fund may invest in ETFs, other registered investment companies or exchange-traded notes (ETNs) to gain exposure to certain asset classes, including commodities. The fund’s allocation to different global markets and to different investment instruments will vary depending on the overall economic cycle and assessment by portfolio management. The fund may also invest in asset backed securities, short-term securities and cash equivalents.

The following disclosure is added under the “MAIN RISKS” section of the fund’s summary prospectus:

ETN risk. Because ETNs are senior, unsecured, unsubordinated debt securities of an issuer (typically a bank or bank holding company), ETNs are subject to the credit risk of the issuer and may lose value due to a downgrade in the issuer’s credit rating. The returns of an ETN are linked to the performance of an underlying instrument (typically an index), minus applicable fees. ETNs typically do not make periodic interest payments and principal typically is not protected. The value of an ETN may fluctuate based on factors such as time to maturity, level of supply and demand for the ETN, volatility and lack of liquidity in the underlying assets, changes in the applicable interest rates, and economic, legal, political or geographic events that affect the underlying assets. The fund bears its proportionate share of any fees and expenses borne by the ETN. Because ETNs trade on a securities exchange, their shares may trade at a premium or discount to their net asset value.

Effective on or about December 9, 2019, the prospectus is supplemented as follows:
