Fellas, I am an options noob so I am charting AAPL options to learn how price moves. At end of day on Jan 21st AAPL was at 82.83. Feb 80 Calls were at 7.45 Mar 80 Calls were at 9.35 Next day AAPL goes to 88.36 or 6.68% increase. Feb 80 Calls were at 10.50 Mar 80 Calls were at 13.10 The stock went up 6.68% and the calls went up ~40%. Why the huge difference? Then Friday the stock doesn't move and both calls lose 4% and 9% respectively(does the Feb call now lose less because it is ITM and earlier to expire?) Today Stock moves up 1.4% and calls move up 8.1% and 8.8%. I kinda understand this move, but not totally why it is so much more than 1.4%. Thanks for any help.
