Over the past year, many M&T Bank Corporation (NYSE:MTB) insiders sold a significant stake in the company which may have piqued investors' interest. Knowing whether insiders are buying is usually more helpful when evaluating insider transactions, as insider selling can have various explanations. However, when multiple insiders sell stock over a specific duration, shareholders should take notice as that could possibly be a red flag.

Although we don't think shareholders should simply follow insider transactions, we do think it is perfectly logical to keep tabs on what insiders are doing.

M&T Bank Insider Transactions Over The Last Year

The Chairman & CEO, Rene Jones, made the biggest insider sale in the last 12 months. That single transaction was for US$4.5m worth of shares at a price of US$194 each. That means that an insider was selling shares at below the current price (US$197). We generally consider it a negative if insiders have been selling, especially if they did so below the current price, because it implies that they considered a lower price to be reasonable. However, while insider selling is sometimes discouraging, it's only a weak signal. This single sale was just 22% of Rene Jones's stake.
