Over the last 36 years whose first five days resulted in a stock market increase, 31 of those years experienced an overall good year for stocks. While that’s a good track record, it’s not an infallible indicator. There are three trading days left in 2008, a lost cause for the stock market.
This method has an 86% success ratio. Will you make any investing decisions based on the market’s performance during the first five trading days of January?

You calculated a success ratio based on years where the first five days showed growth. Did you also calculate the correlation/ratio for years where the first five days showed a (strong) decrease?
Jasper: That’s a good question, I’ll see if I can put the numbers together.
Most definitely not! Relying on this kind of thing is baaaad news. Same as all the junk sports announcers always use: “Teams never come back when they’re down 0-3 in a best of seven series.”
Until it actually happens (see Red Sox). I would urge readers to try to ignore they even heard this.
@ Flexo
I hope you’re right on this because today was definitely a good start. Nice way to start off the year.

No one is talking about this. Everyone is IGNORING THE FACTS.
