No. 1 Google vs. No. 4 Apple

SkyBridge Capital's Anthony Scaramucci said that Google was rising in ownership among hedge funds, while Apple was losing its shine.

"I think Google is the next Apple, where Apple was the next Microsoft," he added. "And if you followed that, you'll stay long Google."

Josh Brown of Fusion Analytics noted that just based on "game theory," Apple had the greater potential because Google was trading near its all-time high.

OptionMonster's Pete Najarian said it's a second-half-of-2013 story for Apple.

"I think what you're going to see is, I think, Google at this $800 level at some point is going to stumble," he said. "It's going to fall. When it pulls back, everybody's going to be whining, 'Where's my dividend?'"

StockMonster's Guy Adami was a backer of Google, tying up the contest.

The "Fast Money" Twitter followers, with the tie-breaker, tipped the scales with top-seeded Google.

No. 6 Microsoft vs. No. 2 IBM

Adami backed Microsoft.

"This goes to the Anthony Scaramucci way of thinking," he said. "I think IBM might have a little bit of a pullback. Mister Softee may be sideways, so I like Mister Softee for the reasons that don't make sense – Microsoft."

Najarian said that he owns Microsoft, but sided with IBM. "I think IBM takes them out earlier," he said.

Brown picked Microsoft, while Scaramucci backed IBM.

"I just think this is the best management team out there for what it does, and you'll see this thing trade up by the end of the year," he said.

The "Fast Money" Twitter crowd broke the tie by siding with IBM.
