Context

• This was a sale (not a purchase); insider sales are common and can reflect many reasons (diversification, liquidity needs, scheduled selling) but do not by themselves prove a change in the director’s view of the company.
• For retail investors, purchases generally signal stronger affirmative conviction than routine open-market sales; treat this single sale as a factual data point rather than a directional signal.
