Geoff Gannon writes this blog post in response to Barron’s “Sell Buffett” cover story. The post looks at a fair value for Berkshire (BRK.A) shares and finds that there is currently no real “Buffett premium” baked into the stock price. In fact, if Buffett gives Berkshire another 9 years, Berkshire may end up being a bit undervalued at the latest price of $143,000 per “A” share.
