Technology companies led a slide in US stocks Friday, adding to the market’s losses from another tech-driven sell-off a day earlier.
Twitter plunged more than 20 percent, its second-biggest loss since going public in 2013, after the social media network said its monthly users declined in the second quarter.
While technology stocks made up much of the market’s drop, smaller-company stocks fell more than the rest of the market. The losses outweighed gains in banks and phone companies.
Even so, the S&P 500, the market’s benchmark index, had its fourth weekly gain in a row.
The week ended largely as it began, with investors focused on a cavalcade of company earnings reports, most of which have topped Wall Street’s forecasts.
‘‘There were clearly high expectations coming into second-quarter earnings and we’ve seen where companies have performed well relative to those expectations, they’ve typically been rewarded, and where they have fallen short of those expectations, either in current quarter or future guidance, is where you’re seeing [selling] occur,’’ said Bill Northey, senior vice president at US Bank Wealth Management.
The S&P 500 index fell 18.62 points, or 0.7 percent, to 2,818.82.
The Dow Jones Industrial Average slid 76.01 points, or 0.3 percent, to 25,451.06.
The Nasdaq composite index, which is heavily weighted with technology companies, lost 114.77 points, or 1.5 percent, to 7,737.42.
The Russell 2000 index of smaller-company stocks gave up 32.02 points, or 1.9 percent, to 1,663.34.
