(NYSE:GRMN) shareholders if they were a little worried about the fact that Matthew Munn, a company insider, recently netted about US$1.0m selling shares at an average price of US$225.

The Last 12 Months Of Insider Transactions At Garmin

The insider, Cheng Wei Wang, made the biggest insider sale in the last 12 months. That single transaction was for US$1.8m worth of shares at a price of US$177 each. That means that even when the share price was below the current price of US$225, an insider wanted to cash in some shares. 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. This single sale was just 23% of Cheng Wei Wang's stake.
