With most investors cowering in the face of a volatile market, now is a good time for investors to jump into deeply discounted stocks across all sectors, Ken Fisher, CEO of Fisher Investments, told "Squawk Box Europe" Thursday.
"People have had their pants scared off of them. Therefore they are running around basically naked," Fisher said.
"And when people are running around basically naked, they're not very rational, so you don't have to be very rational in the purchase process either, you can be broad spectrum and do it like a shotgun," he added.
