David Einhorn: Long on Apple

NEW YORK (TheStreet) -- Famous short-seller David Einhorn of Greenlight Capital bought Apple and increased holdings in Microsoft during the second quarter, according to latest portfolio disclosures with the Securities and Exchange Commission.

The fund -- which has financials, technology and healthcare among its top holdings -- took a fresh exposure to Apple(AAPL), while stepping up exposure to Microsoft(MSFT) and Xerox(XRX).

New additions to the portfolio included financial technology services company NCR(NCR), Lockheed Martin(LMT) and UK-based oil major Ensco(ESV). Einhorn also took tiny stakes in Furiex Pharmaceuticals(FURX), Symmetricom(SYMM) and Oritani Financial(ORIT).

The long-short fund exited completely from nine stocks including URS(URS), Teradata(TDC) and Automatic Data Processing(ADP), which each accounted for about 2% of the March portfolio.

Investors managing over $100 million assets are required to report their holdings every quarter within 45 days from the end of the quarter. The managers do not need to disclose short positions or investments in non-U.S. listed securities.

Einhorn is most famous for his short sale on Lehman Brothers. Markets follow the moves and portfolio disclosures of big investors to get cues on sectors and stocks worth looking at. However, information in these portfolios are often dated and the portfolio manager may have changed his or her tack since the end of the previous quarter. LINK BOX:
