Twitter sees biggest 1-day drop since October as user growth disappoints

U.S. stocks retreated from all-time highs Thursday, with the Nasdaq and S&P 500 falling into negative territory as tech stocks gave up early gains inspired by another round of largely upbeat corporate earnings.

The Dow Jones Industrial Average was up 14 points, or 0.1%, at 21,725, as Verizon Communications Inc.(VZ) shares soared 7% and Merck & Co.(MRK) shares rallied 4.2%. Apple Inc. (AAPL) shares weighed on the index with a 2.2% decline. Earlier, the blue-chip average set an intraday record of 21,790.13.

The S&P 500 fell 12 points, or 0.5%, to 2,466, as industrials fell 0.8% and tech stocks dropped 1.6%, after the index touched an intraday record of 2,484.04. Earlier in the session, the tech sector was up as much as 0.6%.

The Nasdaq Composite Index fell 76 points, or 1.2% to 6,346, after touching an intraday record of 6,460.84.

Stocks pulled back in midday trading as gains in tech stocks swung to sharp losses.

"We're still up for the week but these are the points where people take profits," said Mark Kepner, managing director of sales and trading at Themis Trading. Plus, with the pressure coming midsession a toning down of volume can amplify moves, Kepner said.

After being up more than 5% earlier, Facebook Inc.(FB) shares were up 2.9% a day after the social media giant posted results that beat quarterly earnings expectations (http://blogs.marketwatch.com/thetell/2017/07/26/facebook-earnings-put-instagram-in-focus-amid-shift-in-newsfeed-ads-live-blog/). The company could be nearing a $500 billion market cap (http://www.marketwatch.com/story/facebook-heads-toward-500-billion-market-cap-after-earnings-2017-07-26) if shares maintain their strength throughout the session. The stock has already jumped nearly 50% thus far this year.

Facebook is one of the so-called FAANG stocks, a reference to the quintet of technology and internet names (Facebook, Apple, Amazon (AMZN), Netflix (NFLX), and Google parent Alphabet (GOOGL)(GOOGL) that have driven market returns thus far this year. However, those sharp gains have also raised questions over valuations.

"Tech stocks are having to live up to lofty expectations, given the gains they've experienced this year--particularly in the bigger names--and the levels of growth we're seeing are doing just that," said Craig Erlam, senior market analyst at Oanda, in emailed comments.
