Halma Insider Transactions Over The Last Year

In the last twelve months, the biggest single purchase by an insider was when Senior Independent Director William Rice bought UK£59k worth of shares at a price of UK£19.22 per share. That implies that an insider found the current price of UK£20.61 per share to be enticing. That means they have been optimistic about the company in the past, though they may have changed their mind. While we always like to see insider buying, it's less meaningful if the purchases were made at much lower prices, as the opportunity they saw may have passed. Happily, the Halma insider decided to buy shares at close to current prices. The only individual insider to buy over the last year was William Rice.
