The New York Stock Exchange has released it’s calendar for 2008 and 2009. Get excited because in 2008 there will be two extra trading days! It’s a leap year, giving us an extra day in February. And there is one less holiday on the schedule—this year we honored the death of Gerald “stagflation” Ford by refusing to work. Unless a former president dies this year, we should have one more day of trading.
Leap years tend to outperform other years, with particularly strong Augusts. Of course, leap years are also presidential election years, which may have more to do with market performance than that extra day in February.
