A nitpick: Berkshire Hathaway don't publicise any stock purchases or sales and they don't comment on them. Specifically because they don't want to give out information that will drive up the price quickly. I imagine that's grown harder and harder as time goes on, given the ability of HFT algorithms to spot big purchases in progress. But Buffett has always preferred outright purchases or special one-off deals (eg. the Bank of America deal or individually-negotiated insurance contracts).
