The volatility in FANG stocks shouldn't spook investors. 

That's the assessment from Alex Kenjeev, president of O'Leary Ventures. Kenjeev works closely with Shark Tank star Kevin O'Leary.

According to Kenjeev, FANG stocks are at the center of exciting trends from streaming video to artificial intelligence to self-driving cars. 

Meanwhile, Kenjeev said Facebook's lack of debt makes it largely immune from the Federal Reserve's looming rate increases. 

FANG is an acronym for Facebook (FB) , Amazon (AMZN) , Netflix (NFLX) and Alphabet's (GOOGL) Google coined by TheStreet's Jim Cramer.
