Many Berkshire Hathaway Inc. (NYSE:BRK.A) insiders ditched their stock over the past year, which may be of interest to the company's shareholders. Knowing whether insiders are buying is usually more helpful when evaluating insider transactions, as insider selling can have various explanations. However, if numerous insiders are selling, shareholders should investigate more.

While insider transactions are not the most important thing when it comes to long-term investing, we would consider it foolish to ignore insider transactions altogether.

Berkshire Hathaway Insider Transactions Over The Last Year

In the last twelve months, the biggest single sale by an insider was when the Vice Chairman of Insurance Operations & Director, Ajit Jain, sold US$139m worth of shares at a price of US$695,418 per share. That means that an insider was selling shares at slightly below the current price (US$726,220). As a general rule we consider it to be discouraging when insiders are selling below the current price, because it suggests they were happy with a lower valuation. While insider selling is not a positive sign, we can't be sure if it does mean insiders think the shares are fully valued, so it's only a weak sign. It is worth noting that this sale was 63% of Ajit Jain's holding.
