Start of the Bull Run for Cyber Security stocks?

In the early Dec 2020, FireEye, a top cyber security firm, said it was hack. About a week later, Solarwinds SWI, an IT firm that provides software for companies like the Fortune 500 and the US government was also reported being hacked. The series of the hacking events stir up huge interest back to the cyber security stocks.

Is the rally for cyber security stocks sustainable? Or is it just for swing trading by tapping into the hacking news as catalyst? How about position trading (aka investing) for this sector? To answer these questions, let's take a closer look by analyzing the top 4 ETFs such as HACK, IHAK, BUG, CIBR and some of the outperforming stocks like NET, ZS, CRWD, OKTA, TENB, VRNS, CALX, ALRM, SAIL, RPD, NASDAQ:FEYE and NYSE:PANW.
