Trading Vegas: Plays on 2 casino stocks

What happens in Vegas: 2 casino stocks go head to head

Investors thinking of buying MGM Resorts stock because of Saturday's enormously lucrative boxing match should be wary, CNBC "Fast Money" trader Brian Kelly said Friday.

The welterweight bout between Floyd Mayweather Jr. and Manny Pacquiao—which is expected to break boxing revenue records—will be held at the resort and casino company's MGM Grand in Las Vegas. But Kelly noted that MGM shares have moved only slightly higher ahead of the event, limiting their upside.

"I would just stay away completely from the casino space right now," he said.

MGM shares closed more than 1 percent higher on Friday. Still, the move took the stock barely positive for the year.

Trader Tim Seymour saw great risk-reward in MGM, as it closed just above $21 per share on Friday. It makes a strong investment, not just trade, he said.

MGM looks more appealing than competitor Wynn Resorts, trader Steve Grasso said.

"If you want to play Vegas, you play with MGM," he said.
