Why do put option prices go higher when the underlying stock tanks (drops)?
Options pricing is based on the gap between strike and the current market, and volatility. That's why the VIX, a commonly accepted volatility index, is actually just a weighted blend of S&P 500 future options prices.  A general rise in the price of options indicates people don't know whether it will go up or down next, and are therefore less willing to take that risk.  But your question is why everything underwater in the puts chain went higher, and that's simple: now that Apple's down, the probability of falling a few more points is higher. Especially since Apple has gone through some recent rough times, and stocks in general are seen as risky these days.
