Shia LaBeouf of Wall Street 2: rags-to-riches star picks winning stocks

CANNES -- If you want to play the stock market like Shia LaBeouf, then prepare to zig when the others zag.

"I made most of my money by contrarian investing," the actor said when queried by WalletPop at the Cannes Film Festival this week. "Nobody was putting money into financials, then financials exploded."

He had help. As LaBeouf was preparing to film Wall Street: Money Never Sleeps, which premiered here, he worked with traders and studied for the broker exam. "I was surrounded by a lot of smart people who made picks for me, and they were incentivized to do so because I was the conduit to their hero."
