With 89% ownership in Halma plc (LON:HLMA), institutional investors have a lot riding on the business

Institutional Ownership and Stock Vulnerability: Halma plc has a significant institutional ownership of 89%, making its stock price susceptible to the trading decisions of these investors, particularly given recent insider sales and the concentration of shares among the top shareholders.

Insider and Public Stake: Insiders own less than 1% of Halma, while the general public holds a 10% stake, indicating limited accountability for board decisions; however, the influence of individual investors can still impact company operations.
