Seldom used to try and value BRK but always interesting to look at. Based on the numbers just released annual revenue would be at least $96 billion but that does not include the recent acquisitions of Iscar and Russell so the number should easily be close $100 billion. Thus the P/S is approximately 1.4. General Electic is around 2.1 or so. The value kicker is that BRK is an operating company with a huge investment portfolio.
Will be interesting to see what the next acquisition is.
