There are dozens of major earnings during Tuesday morning hours, with BP, Procter & Gamble, 3M and Eli Lilly among them. But Apple stands tall after the closing bell, following a series of high-profile tech misses and expectations for Apple's profits and revenues to decline. Twitter and AT&T also report after the close.
Apple is expected to report earnings fell to $1.99 from $2.33 per share, on revenues of $52 billion, down from $58 billion, according to Thomson Reuters. That would be the first quarter in 51 in which Apple's revenues would have actually shrunk.
Apple has lost some of its shine as a tech darling, but it still has big impact and is part of the Dow, S&P 500 and Nasdaq. In the past eight quarters, Apple rose 63 percent of the time on the day after earnings, for a gain of 1.25 percent, according to analytics firm Kensho. Its worst performance in those eight quarters was last quarter when Apple missed and iPhone sales disappointed. Its stock fell more than 6.5 percent.
