For the last three years, every January I take a large position in Apple prior to Jobs keynote at Macworld and every year, I have made a healthy few percent (10% two years ago).
Somehow I feel more jittery about this strategy this year. The keynote leaked last night and hence the news might already be priced in. After a healthy 3.5% yesterday, AAPL is down almost 2% with 15 minutes to go before reality distortion field sets in. Will it work this time? This is a big bet for small-fry me. UPDATE: OUCH!
Here are the sites to watch: Macrumours Live for coverage of Steve, Google Finance APPL for 15 min delayed quotes, and Google Finance AAPL discussion forums for a good laugh:
