“Back in December 2006, I wrote about the ‘MacWorld Expo Apple Stock Price Indicator’ which I have been following for years. This is the stock trend of the rising price of Apple Computer stock as the San Francisco MacWorld Expo convention approaches. My previous articles described how in the previous five out of the last six years, Apple Computer stock (AAPL) has increased by at least 8% and as much as 37%, measured from November 15 to the last day of the Expo in January,” Stockerblog writes for SeekingAlpha.

“At the beginning of this year, the stock repeated its performance, rising about 13% from November 15 to the last day of the Expo on January 12. The overall average for the last six years during this two-month time frame was an increase of 14%. What causes this to happen? Probably strong year-end sales of Apple products from holiday shopping, anticipation and release of new products to be released at the Expo, and the heavy promotion of the MacWorld Expo which is indirect stock promotion. As I mentioned in my last article, ‘the product buzz created the stock buzz,’” Stockerblog writes.

“The stock is already up about 19 points from where it was on November 15,” Stockerblog reports.
