Hey Jim, it's my opinion that the Q's option info is pretty much useless for the most part because so many use them and their options to hedge their positions or diversify their portfolios. You really never know what the motivation is behind all that action.
On a stock for example though, for someone to plunk down major money on one side or the other, there's a reason. The Q's are so heavily followed and diverse, there really is no way to predict anything with the options I tend to think.
But as that chart shows, there's major action in those $41 puts which just by it's own nature should act as pretty damn good support. If many are using those to hedge a long portfolio, I would tend to think that many won't let the things fall below that level much.
