Wednesday and Thursday represent one of the most concentrated two days of tech earnings in recent memory as six giant firms representing a combined $4.1 trillion in market capitalization all present their December quarter results.

The party starts today after the close when Facebook (FB) and Microsoft (MSFT) report earnings, continues as Chinese tech giant Alibaba (BABA) reports Thursday morning before the open and kicks into high gear with reports from Apple (AAPL) , Alphabet (GOOGL) and Amazon (AMZN) after the close on Thursday. Whether the tech giants live up to their lofty expectations should go a long way towards determining the direction of the stock market overall this week.

We'll be covering all the reports and live blogging Facebook's earnings today and Apple's earnings tomorrow; please check our home page for more details.

Facebook, Microsoft, Apple and Alphabet are holdings in Jim Cramer's Action Alerts PLUS Charitable Trust Portfolio. Want to be alerted before Cramer buys or sells FB, MSFT, AAPL or GOOGL? Learn more now.
