TCW Transform Supply Chain ETF (SUPP) is an actively managed exchange-traded fund that seeks long-term capital growth by investing primarily in U.S.-listed equities driving and benefiting from supply chain transformation, including relocalization of manufacturing, automation and innovation, and transportation and logistics enhancements; the portfolio holds approximately 23 securities across various economic sectors, with top holdings such as NVIDIA Corporation (NVDA), Waste Connections, Inc. (WCN), and TransDigm Group Incorporated (TDG); it also invests in ADRs and non-U.S. developed or emerging market-listed securities as opportunities arise, employing currency-related transactions or derivatives for risk management. SUPP operates globally through its equity exposures, targeting investors seeking thematic exposure to supply chain resiliency and onshoring trends accelerated by geopolitical shifts and post-COVID disruptions. Launched on February 14, 2023, by Engine No. 1 as part of its Transform ETF platform, SUPP was acquired by TCW Group, Inc. in October 2023 through TCW's purchase of Engine No. 1's entire ETF business, which included SUPP alongside the Transform Climate ETF (NETZ) and Transform 500 ETF (VOTE); this acquisition integrated Engine No. 1's portfolio managers into TCW and expanded TCW's active ETF offerings focused on thematic U.S. equity strategies. TCW, headquartered in Los Angeles, California, with over $204 billion in assets under management as of March 2024, lists SUPP on the Nasdaq exchange following a 2024 change from its prior venue; the ETF maintains an expense ratio of 0.75% and has delivered a total return of 6.93% over the past year as of recent data.
