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) - Get Report and Microsoft (MSFT) - Get Report report earnings, continues as Chinese tech giant Alibaba (BABA) - Get Report reports Thursday morning before the open and kicks into high gear with reports from Apple (AAPL) - Get Report , Alphabet (GOOGL) - Get Report and Amazon (AMZN) - Get Report 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.
