Big tech stocks such as Amazon (AMZN - Get Report) and Facebook (FB - Get Report) have been routed this month on fears of regulation and trade wars descending on the red-hot space. 

Following a better than expected quarter on Wednesday, BlackBerry (BB - Get Report) CEO John Chen weighed in on the tech selloff. 

"Given the fact the market has been in a bull market for so long, and the high-fliers have seen a really big return, I think what we are seeing is a quick knee-jerk reaction to many things going on," Chen told TheStreet. He added that the action in the stocks reflected more profit-taking than gloom on the future of tech.
