SumZero contest's top investment pick

And the best international investment idea is … Samsung.

That was the winning idea submitted by 24-year old research analyst Michael Wood of Evans Investment Counsel as part of FactSet's Top Idea Tournament.

The contest is open to SumZero's 10,000-plus financial professionals. SumZero is partnering with FactSet on the year-long competition.

"We're really trying to highlight up-and-coming investment managers that many people have never heard of," SumZero CEO Divya Narendra said Friday on CNBC's "Halftime Report."

Wood's Samsung pitch beat out hundreds of ideas submitted by SumZero's members.

"It was a phenomenal piece of analysis, one of the most rigorous pitches I've ever seen on SumZero. It was a very impressive piece of work," said Narendra.

Wood defended his pick despite the fact that Samsung pre-announced a challenging quarter.

"I think it's an excellent risk-return here. The one area that is getting mispriced is their memory business. They've been No. 1 in memory for the last 20 years."
