Dow plunges 500 then gains some back

The U.S. joined a global market plunge sparked by growing concerns that the U.S. and Chinese economies are cooling and that equities prices have become overinflated.

Investors' dwindling confidence was knocked down further by data showing that the economy may be decelerating more than anticipated. A Commerce Department report that orders for durable goods in January dropped by the largest amount in three months exacerbated jitters about the direction of the U.S. economy, just a day after former Federal Reserve Chairman Alan Greenspan said the United States may be headed for a recession.

The housing market, which the Street had been hoping had bottomed out, also looked far from recovery after a Standard & Poor's index indicated that single-family home prices across the nation were flat in December. A later report from the National Association of Realtors said existing home sales climbed in January by the largest amount in two years, but the data didn't erase housing-related concerns, as median home prices fell for a sixth straight month.

Let me guess, they're gonna fix this with tax cuts.
