ResMed Insider Transactions Over The Last Year

The Chief Product Officer, Justin Leong, made the biggest insider sale in the last 12 months. That single transaction was for US$10m worth of shares at a price of US$217 each. That means that an insider was selling shares at slightly below the current price (US$254). 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 72% of Justin Leong's holding. Justin Leong was the only individual insider to sell shares in the last twelve months.

Justin Leong divested 54.16k shares over the last 12 months at an average price of US$220.

I like to see this level of insider ownership, because it increases the chances that management are thinking about the best interests of shareholders.
