... for a 29.95/contract debit.
Comments: Erecting a short delta hedge specifically against my IWM longs here, tailored to my specific delta needs, so I've gone with selling the front month 50 and buying the back month 90 for -40 or so delta per contract. (The math just worked out better with multiples of -40 versus multiples of -60; call me delta anal). I've already done a little bit of portfolio-wide SPY beta-weighted delta hedging here using SPY, but wanted to flatten out net delta a smidge further, particularly in my IWM position.
170.05 break even, paying 29.95 on a 35 wide with a max profit potential of 5.05 ($505)/contract.
Generally speaking, you want to address delta imbalances on an instrument by instrument basis first and then look at your portfolio-wide net delta to see if anything additional needs to be done (usually via a broad market, SPY beta-weighted short delta hedge). To a certain extent, this is why you always want to keep some dry powder around -- to adjust your delta on either a per-position or a portfolio-wide basis, some of which may or may not be buying power free.
