Get ready for another full day of earnings and oil price gyrations.

Here are the four things you need to know before the opening bell rings in New York:

1. Crude creeping up: Oil prices continue to push higher Wednesday. Crude futures are currently rising by about 2% to trade around $61.80 per barrel.

The price of a barrel topped $60 on Tuesday, hitting its highest level so far this year.

We could also see brisk trading later this morning when crude inventory data from the U.S. is released at 10:30 a.m ET.

2. Earnings: Anheuser-Busch InBev (AHBIF), SodaStream (SODA) and Wendy's (WEN) are reporting ahead of the open.

After the close, markets will hear from 21st Century Fox (FOX), Tesla (TSLA), Whole Foods (WFM), Transocean (RIG) and Keurig Green Mountain (GMCR).

Shares in BMW (BAMXY) are steady in Europe after the automaker reported its latest quarterly results.

Shares in British grocery chain J Sainsbury (JSAIY) are declining by about 1.5% after the firm reported worse-than-expected results and cut its dividend by 24%. The company, along with rival Tesco (TSCDY), has been suffering from a fierce price war and the cost of writing down its real estate portfolio.
