Google Betas and Stock Price
Mark Evans compares Google's stock price with its launch of new Betas and official products, and Om Malik notes it.
Now, I suspect that Mark was half kidding, but his "analysis" also "inspired" me to look a little deeper.
Of the ten days that Mark notes new product or Beta introductions, Google went up 6 and down 4. On the six up days it gained $17.57; on the four down days, it lost $15.24.
So in other words, on the 10 days Google introduced new products or betas, it had a net gain of $2.33, or $0.23/day. On the 307 days Google didn't introduce new products or betas, it had a net gain of $300.21, or $0.97/day.
Which just goes to show that given five minutes with a spreadsheet and daily stock prices, you can prove just about anything you want.
