Context
These were open-market sales by a company director. Sales are often routine (liquidity or portfolio management) and do not by themselves indicate the company’s future prospects; purchases tend to be more informative of insider confidence. There was no option exercise or immediate cashless sale reported — these were straightforward dispositions.
