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

1. Earnings explosion: Earnings season is in full swing and many big-name companies are reporting results.

Boeing (BA), Coca-Cola (CCE), and McDonald's (MCD) are reporting ahead of the open.

Facebook (FB), eBay (EBAY), and AT&T (T) will release their quarterly results after the close.

2. Stock market movers -- Chipotle, Tesco, Rolls-Royce: Shares in Chipotle (CMG) fell by about 6% in extended trading after the company's earnings missed Wall Street expectations.

Shares in Tesco (TSCDY) were edging up by about 2% in London after the U.K. grocery chain reported a record-setting annual loss of £6.4 billion ($9.6 billion). The company has been struggling for a long time, but investors are betting that management can turn things around.

Rolls-Royce Holdings (RYCEY) shares are rising by 3% in London after the engineering group said it was bringing in a new CEO, Warren East, who previously headed up ARM Holdings (ARMH).

3. Stock market overview: U.S. stock futures suffered an early fall after France said it had foiled a new terrorist plot to attack "one or two churches."

"The sell-off took place on the back of the terrorist news ... and this caused a little bit of panic in the market," explained Naeem Aslam, chief market analyst at AvaTrade.

European markets are also dipping into the red in early trading. Asian markets ended with mixed results.

In Japan, the Nikkei closed above the 20,000 level for the first time in 15 years. The index has surged by just over 15% since the start of the year.

4. Economics: Existing home sales numbers from March will come out at 10 a.m. ET.

Then at 10:30, data on U.S. crude oil inventories will be released.

Crude futures are declining in advance of the report, down by over 1% to trade around $56 per barrel.

5. Tuesday market recap: Trading was bumpy on Tuesday.
The Dow Jones industrial average lost 85 points, while the S&P 500 fell 0.2%. But the Nasdaq rose 0.4%.
