Quote from StockHustler:
Any ideas on why the Nov calls over 200 are the only calls that have actually gone up when the stock has dropped and all other calls have dropped? This is very perplexing to me.
I believe this is because of the volatility. The out of the money calls have bigger proportion of their time premium allocated to volatility (for 210 Nov calls Delta = Vega, look at the other greeks to see the whole picture).
