MARKET SNAPSHOT: Dow, S&P 500 End Higher Amid -2-

Twitter shares log best daily gain since September 2016

U.S. stocks ended mostly higher on Thursday as a fusillade of better-than-expected corporate quarterly results helped to reinvigorate Wall Street buying appetite, a day after the S&P 500 and the Dow posted their biggest drops in more than seven weeks.

The House of Representatives also passed a budget blueprint (http://www.marketwatch.com/story/house-narrowly-passes-budget-in-critical-step-for-republicans-tax-plan-2017-10-26), paving the way for the Senate to eventually pass a tax-reform package by a simple majority. Some analysts view passage of a tax-cut package as critical to extending the stock-market rally.

What are stock indexes doing?

The Dow Jones Industrial Average rose 71.40 points, or 0.3%, to 23,400.86. The S&P 500 gained 3.25 points, or 0.1%, at 2,560.40, while the Nasdaq Composite Index edged down 7.12 points, or 0.1%, at 6,556.77.

Nasdaq was buffeted by weakness in the biotechnology sector (http://www.marketwatch.com/story/biotech-etfs-tumble-with-celgenes-stock-headlining-weakness-2017-10-26), which also weighed on the overall health-care group. The iShares Nasdaq Biotechnology ETF (IBB) slid 2.3% while the health-care sector lost 1%, marking the S&P 500's worst performing sector on the day.

What's driving the market?

The House of Representatives narrowly passed (http://www.marketwatch.com/story/house-narrowly-passes-budget-in-critical-step-for-republicans-tax-plan-2017-10-26) a budget bill on Thursday, which paves the way for the Senate to later pass a tax-reform package with a simple majority, instead of 60 votes.

Earlier in the session, the European Central Bank announced plans to extend the length of its quantitative-easing measures but reduce its monthly asset purchases. The move had been expected, but it represented a very gradual tapering of crisis-era measures by the central bank. The ECB, as expected, left interest rates unchanged and reiterated that it anticipated them to remain at present levels for an "extended period" and beyond the eventual end of its asset buying program.

The markets are also closely monitoring President Donald Trump's coming pick to head the Federal Reserve after Chairwoman Janet Yellen's term ends in February. Yellen is out of the race for the top spot, according to two reports on Thursday (http://www.marketwatch.com/story/yellen-looks-to-be-out-of-the-race-for-fed-chief-2017-10-26), leaving Fed Gov. Jerome Powell and Stanford University economist John Taylor as front-runners.

(http://www.marketwatch.com/story/microsoft-earnings-cloud-may-maintain-600-billion-market-cap-2017-10-25)What are analysts saying?

On the Fed leadership watch, Kevin Giddis, head of fixed income capital markets at Raymond James, said it is likely a three-way race between Jay Powell, John Taylor, and Yellen.

"If it is John Taylor (hawk), look for the 10--year to take out 2.50% without a problem," he said in a note.

What data are in focus?

Weekly jobless claims (http://www.marketwatch.com/story/us-jobless-claims-climb-10000-to-233000-a-week-after-hitting-44-year-low-2017-10-26) rose by 10,000 to 233,000 in the latest week, holding at a historically low level.

Pending home sales (http://www.marketwatch.com/story/pending-home-sales-wobble-to-a-2-12-year-low-2017-10-26) showed a decline to a 2 1/2 year low in September, missing consensus estimates for a rise of 0.4%, as the housing market is buffeted by lean supply and strong demand. Meanwhile, the advanced U.S. trade deficit widened by 1.3% in September.
