$NVIDIA(NVDA.US) was grinding options as usual on Friday. The out-of-the-money calls and puts near 144 were completely crushed. Even if you bought them overnight yesterday, you wouldn't make money today. Many naive investors don't understand what it means to get slaughtered on both long and short positions—this is exactly that. The back-and-forth choppy market quickly crushes the IV of options, especially weekly expirations. The performance shows the stock price moving from the high to low of a range and back again, but the options in hand can no longer return to the prices corresponding to the previous highs and lows. So, naive investors, don't listen to those idiots in the discussion area who use single-leg options to bet on direction—choppy markets with IV crush will grind you to dust.
