The S&P 500 index fell 2%, the Nasdaq fell about 4% and the Dow Jones fell more than 500 points following disappointing financial results from technology companies. Intel shares fell more than 30% after publishing forecasts that turned out to be weaker than expected.

During the week, the S&P 500 fell 1%, the Nasdaq lost 3% and the Dow Jones lost 500 points. During the month, the S&P 500 fell 1%, the Nasdaq fell 7%, and the Dow Jones gained 2%.
