equity markets noting that the decline was the steepest opening day loss since 1983.

Hopes for a strong start to the new year barely lasted a half-hour Wednesday as stocks ran smack into the exact same fears that caused so much trouble in 2007.

All three major stock market indexes started sliding following a morning report showing manufacturing activity slowed in December, and the selling accelerated after oil prices briefly spiked above $100 a barrel. The news fanned concerns that the economy could be teetering on the edge of recession — and triggered Wall Street's worst January-opening performance in 15 years.

Maybe my math is wrong, but that looks more like it should be 25 years, not 15 years.

Floyd Norris at the New York Times reported on the relative damage to the S&P500 via numbers provided by Howard Silverblatt. In this tally, yesterday's 1.4 percent plunge ranks as the 6th worst start to the new year.

Every one of the previous five came when the economy was in a recession, or not far from one.

Here’s the list:

1. 1932, down 3.7% on the first day. Thus began the last year of the worst part of the Great Depression. The National Bureau of Economic Research thinks the recession that began in August 1929 lasted until March 1933.
2. 2001, down 2.8%. A recession began in March.
3. 1980, down 2.0%. A recession began that month.
4. 1949, down 1.6%. A recession had begun in November 1948.
5. 1983, down 1.6%. A recession had ended in November 1982.

Now even if you make the leap that this somehow forecasts the economy, it doesn’t do much for the stock market investor. The stock market had great years in 1980 and 1983, and a good year in 1949. On the other hand, getting out at the beginning of 1932 or 2001 turned out to be a wise decision.

Today should be better.Though it wasn't known until almost a year later, a recession was already officially underway at the time and, as it turns out, the next day was indeed better. After the 1.4 percent drop on Wednesday, the S&P500 finished Thursday exactly where it began at 1447.16.

On Friday, however, the index plunged a whopping 2.4 percent (no, it doesn't seem like a lot now, but it did back then) before going on to lose five percent for the month of January in the beginning of what would turn out to be the worst year for stocks since the Great Depression.
