“That’s why how stocks fare in the first five trading days of January is key. The last 36 times stocks rose at the start of the month, they were higher at year’s end 31 times, the [Stock Trader’s] Almanac says.”
There had never been an NFL team go 0-16 before this year, or 16-0 before last year either. I’m guessing the odds on those events were a lot longer than the odds the first five trading days of 2009 being indicative (7.2 to 1).
