Yesterday, the closing bid on the Jan 2001 50 calls was 50.25. Today it was 56.75, so they are up 6.50. About the only way to know this is to print off the option price sheets every day.

They didn't go up 8 because the delta is less than one. Delta is the amount the call goes up given a one point rise in the stock price. The more "in the money" your calls, the higher the delta, eg, your 50 calls have a higher delta than my 70 calls (which went up 5.625 today). There are many option calculators around (one at CBOE) so you can calculate the delta for your particular calls. Then you know how much of a gain to expect for every point rise in the stock.

Whatever your calls, it was a heck of a day!
