What the price assumes

Your guesses, our math

Move the sliders to your own view of RYTM. Starting points are the company's recent numbers (it isn't profitable yet, so the margin starts at a 10% guess).

Price these guesses point to$13.21-85% vs $89.61 todayAbout -32% a year, before dividends

What today's price needs: with a 10% margin and a 15x P/E, sales would have to grow about 91% 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.
