What today's price needs: with a 5% margin and a 40x P/E, sales would have to grow about 44% a year for 5 years just to match today's price.

Simple math on your guesses, not a forecast or a price target. Real results depend on many things these sliders leave out.

44Mixed

Pre-planned sales of $3.5M (weaker signal)

50 is neutral. Buying by more insiders, top executives and bigger stakes raises it. Selling lowers it; pre-planned sales count less.
