Across Box (BOX), SentinelOne (S), ACI Worldwide (ACIW), Box (BOX) attracts more attention as the best risk/reward idea right now, with Worldwide (ACIW) second and SentinelOne as the speculative growth play. (All fundamentals below are from the Stocks2Buy Fundamentals analysis app, plus recent company reports.)
Key findings:
SentinelOne
Fastest top-line, but weakest fundamentals. Revenue is growing >20% with ARR around $1B and ~75–79% gross margins. However, it still has negative ROA/ROE (≈-18% / -27%), a tiny 0.4% FCF yield and EV/FCF above 200x, meaning the market already prices in a lot of future success while cash generation is only just turning positive. It’s a high-upside cyber/AI name, but clearly high risk.
