Pinterest soars by double digits on debut

U.S. stocks gained Thursday, with the Dow up more than 100 points, as investors continued to analyze the flow of corporate earnings and a series of conflicting economic reports, but sentiment was brightened by strong market debuts from Pinterest Inc. and Zoom Video Communications Inc.

What are indexes doing?

The Dow Jones Industrial Average rose 142 points, or 0.5%, to 26,592 and the S&P 500 index added 7 points, or 0.3%, to 2,907. The Nasdaq Composite Index , meanwhile, reversed its earlier drop to advance 5 points to 8,001.

Stocks are poised to finish the week on a positive note, with markets scheduled to be closed for the Good Friday holiday (http://www.marketwatch.com/story/which-markets-are-closed-on-good-friday-2019-04-15). The S&P 500 was on track for a flat week but the Dow was set to rise 0.7% and the Nasdaq was on pace to finish 0.2% higher.

What's driving the market?

Investors were deluged with a series of new earnings reports and data that sent inconsistent messages about the health of the U.S. and global economies.

The first-quarter earnings outlook has improved somewhat, according to CFRA, which said consensus estimates now call for a 2.3% fall in first-quarter operating earnings a share. That is up from the call for a 3% drop ahead of the kickoff of earnings season, but down from the 4.5% increase projected at the end of last year. Meanwhile, second-quarter earnings are now forecast to eke out a 0.3% advance, CFRA said, which would avert an earnings recession -- commonly defined as consecutive quarters of falling profit.

Retail sales data showed a rise of 1.6% in March, (http://www.marketwatch.com/story/retail-sales-post-biggest-gain-in-1-12-years-point-to-rebounding-economy-2019-04-18) beating consensus estimates. The increase was driven by a 3.5% rise in auto sales, but even with autos and gas stripped out, sales rose by 0.9%, after February's 0.4% decline.

IHS Markit said its U.S. composite PMI -- a survey-based measure of activity in the manufacturing and services sectors -- fell to 52.9 in April from 55.3 in March (http://www.marketwatch.com/story/ihs-markit-pmi-shows-somewhat-slower-us-economic-growth-in-april-2019-04-18), a 31-month low.

Analysts noted that market participants have largely ignored headlines surrounding the Russia investigation and other political turmoil, but some see scope for a negative reaction if the report ultimately appears to be less exculpatory of President Donald Trump and his campaign than characterized by Barr.

New applications for unemployment benefits fell for the fifth week in a row (http://www.marketwatch.com/story/jobless-claims-dive-even-lower-to-192000-sit-at-nearly-50-year-low-2019-04-18) to a near 50-year low of 192,000, below economists expectations of 204,000, per a MarketWatch poll.

The Philadelphia Fed's regional manufacturing index, meanwhile, fell to a three-year low of 8.5, below economists expectations of 11.

U.S. business inventories rose 0.3% in February, according to the Commerce Department (http://www.marketwatch.com/story/us-business-inventories-rise-03-in-february-2019-04-18). The ratio of inventories to sales remained unchanged at 1.39, indicating the number of months it would take to sell inventory on hand.

The Conference Board's Index of Leading Economic Indicators rose 0.4% in March (http://www.marketwatch.com/story/economy-speeds-up-in-march-but-not-at-a-very-fast-pace-leading-indicators-show-2019-04-18), indicating a slight uptick in U.S. economic activity from a weak start to 2019.

The market took the release of Special Counsel Robert Mueller's report on his investigation into Russian election interference in stride. The Justice Department provided the Mueller report to Congress and the public Thursday morning. Portions of the report are be blacked out.

What are analysts saying?

"A lot of good news has already been priced in to the market, and investors are still in search of the next catalyst to drive stocks higher," said Michael Arone, chief investment strategist at State Street Global Advisors. "Investors are still fearful of a global economic slowdown," and want to see a rebound in Europe and more confirmation that China's economy has bottomed, before markets can take the next leg higher, he added.

"There's been a lot of turbulence in retail recently so it's good to see [retail sales data] blow it out of water, and we can likely thank the tight labor market boosting consumer spending," said Mike Loewengart, v.p. of investment strategy at E-Trade Financial Corp., in an email. "The recent uptick in wages and the possibility that we're in a sweet spot with inflation could also continue to drive momentum," he added.
