Our study was conducted in the 6 sector ETFs mentioned above using data from 2005 to the present. We chose the option cycle closest to 45 . We sold at-the-money (ATM) short and , if possible, or held to expiration if we could not. A results table on the sector ETF short Straddles was displayed. The table included the win rate, average P/L, average win and average loss. The table showed that all the ETfs had similar win rates but different P/Ls due the the variation in underlying prices.
