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 months.

The Dow Jones Industrial Average traded 800 points lower as Intel and Microsoft fell more than 3 percent each. The Nasdaq Compositeplummeted 4 percent.

The S&P 500 dropped 3.2 percent, with the tech sector underperforming. The broad index was also headed for a five-day losing streak — which would be its longest since late 2016 — and fell below its 50-day moving average, a widely followed technical level.

The Dow was on pace for its worst day since February.

Stocks have fallen sharply this month. For October, the S&P 500 and the Dow are down more than 3.6 percent and 2.5 percent, respectively. The Nasdaq, meanwhile, has lost more than 6.5 percent.

Rising rate fears and a pivot out of technology stocks have made it a rough last few days. The Dow has dropped four of the last five sessions, losing nearly 900 points over that span.

Shares of Amazon declined nearly 4 percent on Wednesday, while Netflix slid 6.3 percent. Facebook and Apple also fell more than 2 percent each. These stocks are top performers for the year and for most of the bull market.
