So far this season, companies have proven they may be faring better than anticipated. That's due in part to the fact that analysts' earnings estimates have come down in recent months as companies faced foreign exchange headwinds and other growth concerns.
This could set up stocks for rallies on potentially better-than-feared outcomes.
Alphabet and Microsoft are among the companies set to report earnings after the bell as a week with tech as the centerfold continues. Chipotle Mexican Grill is also on deck.
Those reports will come after a smattering of results before the bell.

Coca-Cola also reported stronger-than-forecast earnings, sending the stock up 1%.
