NEW YORK (TheStreet) -- Warren Buffett is among the major Wall Street players whose first-quarter holdings were revealed in the recently-released 13F regulatory filings.
The 13F regulatory filings from some of Wall Street's major players were released on Thursday and traders are taking notice.Warren Buffett bought an 11 million-share stake in Verizon Wireless (VZ - Get Report) valued at $524 million -- joined by Third Point Capital's Dan Loeb, who also disclosed he owned 3.5 million shares worth about $166 million at the end of the first quarter. Hedge fund manager David Tepper sold his Verizon stake, however. Big managers cut their stakes in General Motors (GM - Get Report) as the automaker recalled a record number of vehicles. The Oracle of Omaha reduced his position in GM by 10 million shares, while David Einhorn's Greenlight Capital unloaded all of its 17 million shares in the automaker. Einhorn decreased his ownership in Apple (AAPL) by 13%, but held onto 2.1 million shares, while stepping up his investment in solar energy company SunEdison (SUNE) by more than 800% or 10.5 million shares. He now holds more than a 4% of the company's shares. Einhorn also bought into Nokia (NOK), however, with a 3.5 million-share position prior to the closing of the company's sale of its phone unit to Microsoft (MSFT). Dan Loeb maintained a 4.5 million-share position in Nokia in the first quarter. The filings pertain to the investors' holdings as of the end of the first quarter. They don't reveal what the managers have done since the end of March. In New York, I'm Brittany Umar for TheStreet. -- Written by Brittany Umar in New York.
