Buffett Sells BofA Stock Again, and Soon He May Trade in Secret

Warren Buffett’s Berkshire Hathaway Inc. won’t have to swiftly disclose its rapid-fire sales of Bank of America Corp. stock too much longer. That is, if he keeps whittling the investment.

A fresh round of disposals disclosed late Friday trimmed the conglomerate’s stake in the bank down to 11.4%. So long as Berkshire holds more than 10%, US rules require it to reveal transactions within a few days. But if the company holds less, it may wait weeks to update the public — typically giving snapshots after every quarter.
