Steve Jobs gives a legendary keynote at Macworld SF every January, launching products and giving a state of the union view of things at Apple. I wondered what effect the Jobs keynote had on Apple's (AAPL) stock price in the short term. What if you invested $10,000 the day before the keynote, then sold at the end of the keynote day? What if you waited until the day after? What if you did this every year for the past ten years that Jobs has been doing them? Is it possible to make money off the Apple keynote talks given by Steve Jobs?
