One year ago you purchased a straddle on SPY with a strike price of $50 and one year to maturity when SPY was trading at $49.52. A straddle is an options strategy that consists of buying a call and buying a put with the same strike price and the same expiration date. You paid $3.52 for the call and $2.51 for the put. Today the options are expiring and SPY current price is $58.31. What was the holding period return on this straddle?
