Stocks fight for gains as oil tumbles; Disney earnings after hours

After initially dropping with global markets, stocks fight for gains despite a big tumble for oil. Yahoo Finance’s Nicole Sinclair broke down the wild action in the market today.

Winners and losers

Stocks slipping into the red today include Time Warner shares under pressure, Sears after earnings, and Viacom - as the power struggle for the media conglomerate unfolds in the boardroom, Viacom's shares are sliding as weak ad sales hit revenue.

Stocks pulling higher today include Wyndham Worldwide on earnings, Netflix on a bounce back, and Salesforce.com, the world's largest provider of CRM software, popping after Jefferies upgraded it to hold, claiming the recent drop in shares was overdone and improved traction in sales.

More volatility ahead?

Will the market's winter of volatility continue into the spring? Russ Koesterich, chief investment strategist for BlackRock and iShares, joined the Final Round to tell us why he expects a bumpy road ahead.

Looking ahead

• Fed Chair Janet Yellen heads to the Hill, presenting the Fed's semi-annual monetary report to the House Financial Services Committee in Washington.

• Oil traders are bracing for more data in the pipeline, with the EIA's weekly status report on U.S. crude oil inventories. Another build in inventories could send already depressed prices lower.

• Finally, we'll have some big earnings reports from Twitter, Cisco, and Tesla after the bell—we'll have all of those reports for you in tomorrow's Final Round.
