Over the past year, many Berkshire Hathaway Inc. (NYSE:BRK.A) insiders sold a significant stake in the company which may have piqued investors' interest. When evaluating insider transactions, knowing whether insiders are buying is usually more beneficial than knowing whether they are selling, as the latter can be open to many interpretations. However, if numerous insiders are selling, shareholders should investigate more.

Although we don't think shareholders should simply follow insider transactions, we would consider it foolish to ignore insider transactions altogether.

The Last 12 Months Of Insider Transactions At Berkshire Hathaway

Over the last year, we can see that the biggest insider sale was by the Vice Chairman of Insurance Operations & Director, Ajit Jain, for US$139m worth of shares, at about US$695,418 per share. So it's clear an insider wanted to take some cash off the table, even below the current price of US$784,000. When an insider sells below the current price, it suggests that they considered that lower price to be fair. That makes us wonder what they think of the (higher) recent valuation. However, while insider selling is sometimes discouraging, it's only a weak signal. We note that the biggest single sale was 63% of Ajit Jain's holding.
