Hedge fund luminaries such as David Einhorn, Jeff Gundlach, and John Paulson listed some of their investment choices at a recent conference in New York.

Einhorn of Greenlight Capital cited reasons to short Martin Marietta Materials, The Wall Street Journal reports.

The stock has "a lot of problems," he says. In particular, CEO Howard Nye has put his desire to purchase rival Vulcan Materials above shareholders’ interests, Einhorn says.

Einhorn and DoubleLine Capital’s Gundlach took opposite bites into Apple. Gundlach says he has shorted the market darling.

"I just wonder how many people will queue up around the block for an iPad 87," he says. But Einhorn defended the company.

As for Paulson & Co.’s Paulson, he likes Caesars Entertainment, AngloGold Ashanti, and CVR Energy.

At Caesars, "earnings are again starting to grow as their sector recovers," Paulson says. He sees strong growth opportunities.

Gold miner AngloGold Ashanti has seen its stock drop in recent years, even as the price of gold has risen. "For me, that represents an opportunity," Paulson says.

At CVR Energy, corporate raider Carl Icahn has made a takeover. That “gift” led to Paulson’s investment, he says.

Remember to do your own research before copying any of these moves.

Even if you determine the investment is a good one, the hedge fund may have entered at a much more attractive price than you would. And the heavyweights’ comments alone may already have made the investment more expensive.
