Netflix just at the beginning of its potential, shareholder says

Corporate insiders buying Netflix shares, should you?

With shares of Netflix down more than 15 percent this year, investors have a prime opportunity to buy the stock, shareholder Ross Gerber said Thursday.

The move lower comes after the streaming service had a huge run last year.

"When you have a 150 percent year, of course you are going to take some time to consolidate here before you move to a new level," the CEO and president of Gerber Kawasaki said in an interview with CNBC's "Closing Bell."

Company insiders are certainly optimistic shares will run higher. According to Argus Research, they've been buying up the stock.

"There's billions of potential customers. I really think they're at the beginning. The world is a huge place," Gerber said. "Netflix is just scratching at an enormous market."

Barton Crockett, senior analyst at FBR Capital Markets, isn't convinced the stock will move higher, despite the fact that it has a "brilliant" management team.

He has a "market perform" rating and $90 price target on the stock.

That's because the numbers indicate the company has hit a saturation issue in the United States, with over half of all broadband customers subscribing to Netflix, Crockett told "Closing Bell." He believes there are also "saturation question markets" internationally as well.

"You kind of see a company with decelerating subscriber growth. You have a company where they drink the Kool-Aid internally and that drives them to spend a lot more on content," he said.

"In that environment, I think there's risk that they get overly ambitious. They spend more based on anticipation of growth that they're not able to get because the market is getting saturated," he said.

He'd rather sit back and let the company consolidate and mature and not chase it right here.
