The numbers speak for themselves. The market for short-term options has proliferated during the past year and is now hitting daily notional volumes of US$1 trillion, according to a recent report from J.P. Morgan Global Markets on February 15th. And it isn’t just institutional traders using zero day to expiry (0DTE) call and put strategies. In fact, a growing number of retail investors is also trading them, lured by the opportunity to gain big returns in a small window of time.
