NEW YORK (CNNMoney.com) — Stocks slumped Tuesday, with the Dow industrials ending at a 3-month low, as the government’s bank rescue plan failed to reassure investors burned by the 14-month old recession.

Treasury prices rallied, lowering the corresponding yields, and the dollar slipped versus other major currencies.

The Dow Jones industrial average (INDU) lost 382 points, or 4.6%, closing at its lowest point since Nov. 20, the date considered by many experts to have been the low of the bear market. The Dow had lost as much as 422 points in the afternoon.

The Standard & Poor’s 500 (SPX) index lost 43 points, or 4.9%. The Nasdaq composite (COMP) lost 66 points, or 4.2%.

The TARP announcement “was a huge disappointment,” said Stephen Stanley, chief economist at RBS Greenwich Capital. “There’s been an incredible buildup for weeks and then they release a plan that has little in the way of details.”
