What’s David Einhorn Up To?

Greenlight Capital’s David Einhorn made a splash this week by seeking a seat on the board of troubled solar company SunEdison (SUNE). SunEdison’s stock is down nearly 90% since July, though Greenlight has been adding to its position since the beginning of this year and now owns about 6% of the company.

While SunEdison is getting the headlines right now, I’m more interested in some of Einhorn’s other investments. Einhorn, like a lot of aggressive hedge fund managers, runs a concentrated long portfolio. So the movement of a single stock or two can have an outsized impact on his portfolio. And Einhorn — like a lot of value managers, myself included — has taken his lumps  over the past year.

At any rate, let’s take a look at what Mr. Einhorn has in his portfolio:

Symbol Company Value ($1,000) % of Portfolio % of Company AAPL Apple Inc 1,238,368 20.53 0.20 GM General Motors Co 489,290 8.11 1.05 KORS Michael Kors Holdings Ltd 297,526 4.93 3.83 CBI Chicago Bridge & Iron Co 296,714 4.92 7.13 CNX Consol Energy Inc 290,173 4.81 12.93 AER AerCap Holdings NV 280,854 4.66 3.72 TWX Time Warner Inc 262,261 4.35 0.48 GRBK Green Brick Partners Inc 261,204 4.33 49.41 MU Micron Technology Inc 185,332 3.07 1.19 ACM Aecom 177,974 2.95 4.27 ON ON Semiconductor Corp 162,673 2.70 4.19 BK Bank of New York Mellon Corp 156,600 2.60 0.37 VOYA Voya Financial Inc 141,487 2.35 1.69 SUNE SunEdison Inc 133,586 2.21 5.87

With the exception of SUNE, which reflects recent buying, the rest of these holdings are as of September 30. We should get updated numbers for the fourth quarter in a little over two weeks. (I should also mention that these are his long positions only; Einhorn also runs a short book, though those positions are not disclosed.)
