Defiance ETFs is seeking U.S. Securities and Exchange Commission approval for 16 leveraged exchange-traded funds designed to deliver twice the return of selected stocks or ETFs over one-hour periods. The proposed products would use the same basic structure as existing 2x single-stock funds but reset exposure at the end of each hour instead of once after the regular U.S. trading session. Targets would include widely traded names such as Nvidia and Microsoft, as well as the Roundhill Memory ETF. Defiance said the funds could begin trading in November if regulators do not object. Repeated hourly compounding could produce larger gains when markets move consistently in an investor’s favor, but reversals and choppy trading could turn a positive daily move into a loss. The filing comes as regulators review increasingly leveraged ETFs; the SEC has blocked proposed products targeting three or five times an underlying stock’s daily return. Defiance said the hourly funds are intended only for knowledgeable investors able to monitor their portfolios throughout the day.
