Here comes Apple, Twitter, and Chipotle

Stocks are on edge as huge after-hours earnings are coming our way - with all eyes on Apple, Twitter, and Chipotle. Catch The Final Round at 4 p.m. ET with Jen Rogers and markets correspondent Nicole Sinclair.

The business of horse racing

When people think of horse racing, they think Churchill Downs. With the new season starting this weekend, we spoke to CEO William Carstanjen earlier today about the business of horse racing and how Churchill Downs is racing to stay on top.

Winners and losers

Stocks slipping today include appliance maker Whirlpool on an earnings and revenue miss, Nabors Industries on quarterly revenue that came in well below estimates, and Sarepta - the drug maker tumbling after an FDA panel gave its Duchenne muscular dystrophy drug a negative recommendation, claiming it wasn't effective.

Stocks on the move higher today include Ethan Allen on an earnings and revenue beat, chipmaker NXP Semiconductor on strong guidance, and The Container Store as revenue topped expectations. The storage company also said it would cut jobs and freeze wages in order to restore profit growth.

Looking ahead

• We'll get market-moving data for oil with the EIA's crude inventory report. Last week we saw a build of 2.1 million barrels of oil.

• We'll get big earnings reports from the likes of Comcast, Boeing, United Technologies, and of course, Facebook.

• And the FOMC's April policy meeting ends tomorrow at 2 p.m. ET. Rates are expected to stay unchanged, but the language in the policy statement will of course be closely scrutinized.
