I ended up with a naked DEC 470 put after unwinding some other positions today. Of course before that it was pushing 500 and afterwards it tanked to 491-something. I thought 30 points was a comfortable cushion, but this is GOOG after all and it could drop 30 points if Bernanke or someone farts the wrong way. Any advice? Just buy to close? Turn it into a spread? Anything else? TIA.
