Dow plunges more than 800 points in worst drop since February

Stocks sank on Wednesday as a steep decline in tech shares and worries of rapidly rising rates sent Wall Street on pace for its worst day in eight months.

The Dow Jones Industrial Average closed 831.83 points lower at 25,598.74 as Intel and Microsoft fell more than 3.5 percent each. The Nasdaq Composite plummeted 4 percent to 7,422.05.

The Dow also closed near its lows of the day.
