you could also hedge by buying a put and then selling a put of the same strike and maturity in the same underlying. it's probably the lowest cost you can do.
Perhaps you could post an actual example with number of SPY shares, option strikes/expiry and the respective bid/ask. Once you go through that I'm sure it won't look so good. When it comes to hedging it's best to SELL if you own and BUY if you want it.
Buy a put and sell a put of the same strike and maturity? Unless I am missing something you are just opening and closing a put position...
Yup. Making a point that if you are going to buy protection to hedge, don't sell the similar protection.
Doesn't make any sense to me of buying/selling same option, make more sense of buying one month option and selling 4 month option of same strike? Then becomes more of a credit spread.
