Billionaire David Einhorn’s High Upside Potential Stocks Include Apple Inc. (AAPL)

Delphi Automotive PLC (NYSE:DLPH) was another of Einhorn’s top picks with the filing disclosing ownership of almost 8 million shares. As with GM, skepticism about the auto industry (Delphi manufactures auto parts including electrical, electronic, and powertrain components) is holding the stock at value levels but the sell-side expects weak performance to flip to considerable earnings growth. A number of other hedge funds like Delphi: billionaire John Paulson’s Paulson & Co., for example, had 13.5 million shares in its portfolio at the end of December (check out Paulson’s favorite stocks).

The fund added shares of NCR Corporation (NYSE:NCR), a $4.5 billion market cap provider of cash register machines, self-service kiosks, and related products. While earnings have been low at NCR recently, analyst consensus implies a forward P/E of 9 and a five-year PEG ratio of 0.7. Given that recent growth numbers have not been particularly good- revenue rose only 3% last quarter compared to the fourth quarter of 2011- we would need more convincing to recommend buying. Eric Bannasch’s Cadian Capital cut its stake slightly but still owned 6.5 million shares at the end of the fourth quarter.

Greenlight kept its position in ENSCO PLC (NYSE:ESV) constant between the beginning and end of Q$ at 3.8 million shares. ENSCO is a contract offshore driller with a market capitalization of $13 billion. It carries trailing and forward P/Es of 12 and 7, respectively, demonstrating that Wall Street analysts expect strong growth considering the current valuation in the market. The stock also pays a dividend yield of above 3% going by current prices and recent dividend payments. Arrowstreet Capital was moving heavily into the stock last quarter (see more stocks Arrowstreet was buying).
