In plain words: Insiders are the people who run or own a big part of the company. Buying with their own money can signal confidence; selling often has personal reasons, like taxes or diversifying.

At 31x, earnings only need to grow 2.0% a year for the share to be worth todayβs price in 5 years. Faster, you gain; slower, you lose.
These are examples, not forecasts: nobody knows which will happen. Price in 5 years = earnings per share then Γ the P/E then. Dividends are not included.
