NYSE trader Kenny Polcari said tech earnings will "blow the roof off the house."

The tech parade begins Monday with Alphabet (GOOGL) and continues on Wednesday with Facebook (FB) and Amazon (AMZN) on Thursday.

However, when you remove tech's performance from the market's this year, there isn't much gain, which is concerning to Polcari. Tech continues to encompass an overwhelming portion of the broader market, given the near-trillion dollar market caps for many of the top tech names. 

All three stocks are holdings of Jim Cramer's charitable trust Action Alerts PLUS.
