The investment vehicle of legendary investor Warren Buffett increased its stake in transport outfit Union Pacific Corp. by almost double in the second quarter.

Berkshire Hathaway also added stakes in Bank of America Corp. (BAC), Lowe’s Cos. (LOW), and NRG Energy Inc. (NRG), according to filings released this morning.

Berkshire Hathaway (BRK.A) grew its Union Pacific (UNP ) stake from 4.453 million shares at the end of the first quarter to 8.906 million at the end of the second quarter. Union Pacific stock is up 23.6% this year…

Berkshire addition of NRG Energy Inc (NRG ) totaled 3.24 million shares in the second quarter, worth $139 million. While NRG’s stock is down 18.7% this year, the energy sector is considered a good investment by money managers right now.

The two sell-offs in Berkshire’s portfolio in the recent quarter were both related to acquisition deals. Trane Inc. was sold off in an acquisition by Ingersoll-Rand Company Ltd (IR). Similarly, Berkshire eased its stake in Anheuser Busch Cos. from more than 35 million shares to less than 14 million shares in the wake of Anheuser’s merger with InBev which had yet to be consummated as of the second quarter.

MarketWatch’s Greg Morcroft also reported this morning:

Shares of Lehman Bros. Holdings Inc. rose more than 6% at one point Friday as news that famed investor George Soros’ hedge fund boosted its stake in the company brought out buyers.

An analyst report from David Trone at Fox-Pitt Kelton also lent support to the shares. He said that Lehman’s upcoming losses should be smaller than the second quarter’s as hedges in place at the firm appear to be working.

Soros Fund Management has raised its stake in Lehman Brothers (LEH) to 9.47 million common shares at the end of June 30, up from 10,000 shares at the end of March 31.

The fair market value of the stake is estimated at $187.7 million, according to a regulatory filing by the fund Thursday.

Reuters’ Karen Wutkowski noted yesterday:

Billionaire investor Eddie Lampert cut his stake in Home Depot Inc (HD.N) by 13 percent to 19.7 million shares as of June 30, according to a disclosure document for his fund RBS Partners.

The fund also increased its stake in AutoZone Inc (AZO.N) to 22.9 million shares from 22 million shares the prior quarter, according to a filing with the U.S. Securities and Exchange Commission. It cut its stake in KB Home (KBH.N) to 358,000 shares from 605,000 shares.

Looks like billionaire hedge fund manager Eddie Lampert thinks the U.S. housing bust is almost over. According to the Wall Street Journal this morning, Lampert has been acquiring shares in beaten-up home builders, mortgage lenders, and a home-improvement retailer. The Journal’s Gary McWilliams wrote:

Recently, the Greenwich, Conn., hedge fund, which controls investments it valued at about $11.6 billion in its most recent government financial report, began picking up shares in hard-hit housing-related stocks. ESL acquired small stakes in U.S. home builders Centex Corp. and KB Home, according to its latest Securities and Exchange Commission filings. At recent prices, the stakes in the two home builders are valued at $10.4 million and $10.8 million, respectively.

ESL also is tip-toeing into mortgage origination and servicing, acquiring about four million shares of CIT Group Inc., a struggling subprime home and commercial lender, as well as 1.4 million shares of PHH Corp., a mortgage originator and mortgage-service company. The shares are valued currently at about $35.5 million and $25.2 million, respectively. ESL spokesman Steve Lipin declined to comment on the investments.

McWilliams also noted that Lampert, who is also the chairman of Sears Holding Corp., added to his holdings of home-improvement retailer Home Depot. His hedge fund now owns about 22.7 million shares (valued at $590 million), up from 16.7 million shares in 2007.
