Warren Buffett, the Chairman & CEO of Berkshire Hathaway (BRKA), is probably the most well known investor in the world. Many investors like to piggyback off of his investments, in order to match his great returns.

On February 14, Berkshire Hathaway reported its holdings on Form 13F to the Securities & Exchange Commission. The most interesting part of the filing are the stocks that Buffett has added to the Berkshire portfolio.

First, one of his new positions is Southwest Airlines (LUV), acquiring 43,195,053 shares. Buffett also added to his positions in other airlines, such as Delta Air Lines (DAL), increasing the position almost ten fold  from 6,333,923 to 60,025,995.

Another airline he likes is United Continental (UAL) where holdings have gone up by 24,418,340 shares, from 4,533,013 to 28,951,353.

In the tech area, Buffett likes Apple (AAPL). The Berkshire holdings went up from 15,227,702 shares to 57,359,652 shares. Holdings also rose in American Express (AXP) and Bank of New York (BK).

You have to admit that Warren Buffett has an outstanding track record. Following in his footsteps may be a strategy worth considering.
