Unfortunately you can't imitate him with high accuracy the way you could with an ETF since they have a number of wholly-owned subsidiaries. That's also what allows their stock to get out of alignment with market value of their holdings.

You can get a good idea of whether Buffett thinks Berkshire is undervalued or overvalued by whether he uses cash or stock for acquisitions, though. When the stock is overvalued, he'll trade overvalued Berkshire stock for undervalued other stocks. When the stock is undervalued or fairly-valued, he'll use cash for the purchase.

Everything recent has been done with cash, AFAIK.

Yeah, that's true. I just wish you could imitate him like an EFT.
