❓ FAQ

What is a Rule 10b5-1 trading plan?

It is a regulatory mechanism that allows corporate insiders to set up a pre-determined schedule for selling stock, helping to decouple trades from the possession of material non-public information.

Why is the Chairman's sale considered a potential risk?

While the sale may be for personal diversification, a $51.3 million divestment by a founder-level executive can signal a lack of confidence in the stock's future upside, especially when the company is trading at high valuation ratios.
