What the price assumes
Your guesses, our math
Move the sliders to your own view of RBBN. Starting points are the company's recent numbers (it isn't profitable yet, so the margin starts at a 10% guess).
Sales in 5 years$526M
Profit in 5 years$53M
Price these guesses point to$3.92+192% vs $1.34 todayAbout +24% a year, before dividends
What today's price needs: with a 10% margin and a 17x P/E, sales could shrink about 26% a year for 5 years and still 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.
Forum talk counts mentions of RBBN in popular online stock forums, a slice of the internet rather than all of it. Company lookups show interest in the company itself, which can come from news that isn't about the stock. Attention isn't quality.
