Weak earnings, data continue to weigh on shares

The Dow Jones Industrial Average was off 100 points Friday as shares struggled to hold on to their monthly gains with sour earnings reports and weak economic data weighing on sentiment.

The Dow Jones Industrial Average was down 103 points, or 0.6%, to 17,781. Intel Corp. and UnitedHealth Group Inc.(UNH) were the worst performers.

Meanwhile, the S&P 500 dropped 10 points, or 0.5%, to 2,065, led by declines in health care and information technology shares. The Nasdaq shed 30 points, or 0.6%, to 4,775.

A rough week of trading erased most of what were once strong monthly gains for the main indexes. The Dow and S&P 500 were up just 0.3%. The Nasdaq, continued to lag behind, on track for a 2% monthly drop.

While the earnings flow was light in the early morning, stocks were still reeling from a sharp selloff in the second half of Thursday's session that was driven by a number of factors--including a weak reading on U.S. first-quarter gross domestic product, a surprise decision by the Bank of Japan to leave monetary policy on hold, and Apple Inc.'s first drop in quarterly revenue in 13 years.

The Dow industrials stumbled more than 200 points (http://www.marketwatch.com/story/dow-faces-near-100-point-loss-as-boj-surprises-market-with-no-change-2016-04-28) on Thursday for their worst drop in two months.

"When you get that kind of late day price action when the market is higher most of the session then just pukes into the close, that means the tone has shifted under the surface," said Mike Antonelli, equity sales trader at R.W Baird & Co. "You've kind of run out of steam at 2,100."

Official data showed consumer spending barely rose in March as consumers opted to save, stoking concerns that second quarter growth might also disappoint after a report on first quarter growth released Thursday was weaker than expected.

The PCE price index, the Federal Reserve's preferred measure of inflation, showed price pressures abated in March, seeming to confirm fears voiced by Fed Chairwoman Janet Yellen that the rise in inflation seen at the beginning of the year might not endure.

"Consumers are two-thirds of the economy and they're not spending much. It's going to be hard to get the data to look much better without them," said Paul Nolte, portfolio manager at Kingsview Asset Management.

Data: Personal income and outlays data showed consumer spending rose a meager 0.1% in March, missing Wall Street expectations. (http://www.marketwatch.com/story/consumer-spending-rises-scant-01-in-march-2016-04-29)

The PCE price index, the Federal Reserve's preferred measure of inflation, showed that price pressures seen earlier in the year have abated somewhat, with the index rising just 0.8% in the 12 months ending in March.

More data lies ahead. The Chicago purchasing managers survey for April is coming at 9:45 a.m., followed by consumer sentiment for April at 10 a.m.
