Stockpickr: Trade Like the Berkshire Board

Keough is also the chairman of boutique investment banking firm Allen & Company, which has been a large shareholder of Coca-Cola and owns 22% of Convera.

Convera, with a $190 million market cap and only $16 million in revenue (and $47 million net cash in the bank), is not cheap by value standards. But if the idea of search in the enterprise universe takes off, the company could easily be an acquisition candidate for a larger entity such as Oracle(ORCL Quote) or Microsoft.

Looking at Yahoo! and Intel(INTC Quote) next, both companies -- as well as Berkshire Hathaway -- are connected through Sue Decker. As I noted earlier, Decker is the CFO of Yahoo!, and she also sits on the board of Intel and is a brand new member of the board of Berkshire Hathaway. Decker has often been thought of as a possible successor to Yahoo! Chairman and CEO Terry Semel.

Yahoo! is another company that isn't cheap by value standards, but one that could get cheaper. Over the past 12 months, it has had EBITDA (earnings before interest, taxes, depreciation and amortization) of $2 billion on revenue of $6.53 billion.
