MARKET SNAPSHOT: Stock Market Storms To Session High, Pares Weekly Loss

Deere, Applied Materials, Ross Stores shares on the move

U.S. stocks advanced for a second straight session on Friday, cutting into sharp losses for the week, after a drama surrounding the White House abated.

The S&P 500 index added 20 points, or 0.9%, to 2,385, with all of its 11 main sectors trading higher. The financials, energy and industrials sectors led the gains, all up more than 1%.

The Dow Jones Industrial Average gained 170 points, or 0.8%, to 20,833. Caterpillar Inc. (CAT) and General Electric Co.(GE) were leading the gains, up nearly 2%.

The Nasdaq Composite Index surged 44 points, or 0.7%, to 6,100, powered by more than 2% gains in U.S. shares of Baidu Inc.(BIDU), Nvidia Corp.(NVDA), and Starbucks Corp.(SBUX)

For the week, however, all three indexes are looking at losses of 0.2% to 0.3% following Wednesday's sharp downdraft. Friday's jump helped to cut into what would have been at least 1% losses for the equity benchmarks.

"Over the past two days the news cycle went from the intense inferno-type fire to just regular fire, allowing markets to calm down," said Tom Siomades, head of the Investment Consulting Group of Hartford Funds.

Markets were rattled earlier this week, with investors caught off guard Wednesday following a report that President Donald Trump in February asked then-Federal Bureau of Investigation Director James Comey to stop an investigation into Russian interference into the U.S. election, causing some investors to question whether Trump will even finish his term. Stocks started to bounce back on Thursday after Deputy Attorney General Rod Rosenstein appointed former FBI Director Robert Mueller as special counsel ( to oversee the bureau's investigation.

That appointment did a lot to placate skittish investors, and allow the focus to go back to economic growth more rooted in current business conditions than those more favorable conditions that could get derailed with the drama out of Washington, said Diane Jaffee, senior portfolio manager at TCW

"Clearly, appointing Mueller was brilliant," Jaffee said. "Regardless of who is in office you want the rule of law. You want that the government will prevail in maintaining checks and balances."

Even with weak GDP growth in the first quarter, which even the Federal Reserve called "transitory" (, what many people overlook is that business investment surged 9.4% in the quarter, and not because of election promises, Jaffee said.

As earnings are finally beginning to grow at a healthy pace and fewer companies are cutting costs to pad their results, we're beginning to see business investment, which Jaffee said has "been a long time coming."

Still, investors have increasingly questioned whether President Trump can deliver on his economic stimulus promises amid investigations.

"This week political risk has caught up on the market but it's still unclear whether it has any legs," wrote Deutsche Bank strategist Jim Reid and research analyst Craig Nicol in a note to clients Friday.

"Whether this latest Trump bout of volatility lasts depends on what Mr. Comey really has on the president, but there wasn't much new news to report on the story yesterday which helped U.S. equities to recover," said the Deutsche Bank team.

Observers said investors will be closely watching potential developments on the controversy next week. Lawmakers have asked the FBI to turn over the notes Comey said he made from his meetings with Trump by next week, and a congressional hearing on the matter is due to take place, at which the former FBI head has been asked to testify.

Economic data and Fed speakers: Once again, there are no data points to distract investors from the political roller coaster.

St. Louis Fed President James Bullard questioned the need for a June rate increase (, citing a slowdown in the U.S. economy during the first half of the year. Bullard isn't a voting member of the Fed policy committee this year.
