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.

Share in 5 years

If you put in $1,000 today: $1,116
At 31x, earnings only need to grow 1.7% 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.

Adds net cash of β$3.9B and divides by 67.7M diluted shares. Ten years of cash flows plus a terminal value, discounted to today.

β
Reference multiples: today 31.3x Β· peers 53.8x Β· sector 33.5x.
In plain words: In the long run a share tends to follow two things: how much the company earns per share, and how many times those earnings the market is willing to pay (the P/E). Move those two levers and you see what the share could be worth. Different guesses give very different answers.
