That is a reasonable strategy assuming you are really pretty decent at forecasting the bear move- BUT that IV spike you are hoping for will be dampened by the shift in the skew bec the OTM strike is now the ATM strike so keep that in mind.
Lets say I have a short bias on a stock over the next couple weeks. No price target, nothing more than a bearish directional bias. I'm thinking of the pros and cons of trading an initially delta neutral strategy of long slightly OTM puts with long stock. My reasoning is that if I am correct, I should see profit through an increase in IV, and if the price tends to be more directional vs rangebound I can make money via gamma as price moves towards my strike. If I rebalance daily (or intraday if I think I can read charts) via stock then essentially I limit my loss to theta minus gamma profits, with the potential for a windfall profit if IV spikes. I'm not too experienced with options, mostly have studied them vs traded them. Does this sound reasonable or worth the effort and transaction cost vs a straight short?
take the advise from Kim. Wth Vol so cheap, otm put calendars are prob the best way to harness a bearish foreast.. 2nd place is a put vertical with the long leg being the ATM put.(you get some skew benefit as well.
