SentinelOne (S) and Zscaler (ZS) both compete in next-generation cybersecurity, yet their 2026 trajectories could hardly have been more different. A $10,000 position in SentinelOne opened on January 2 grew to $13,695 — a 37% return — while the same bet on Zscaler shrank to $7,003, a loss of 30%. The gap between those two outcomes widened to $6,692 inside a single year.
The chart tells a tale of two paths. SentinelOne spent much of the first half underwater before surging through mid-year, briefly touching the $13,000 range before closing near its peak. Zscaler moved in the opposite direction, sliding sharply from the opening weeks and spending extended stretches below the $6,000 mark on a $10,000 basis before a partial recovery left it still deeply negative at year-end.

For investors who treat cybersecurity as a single, monolithic theme, the contrast is a reminder that sector-level conviction and stock-level outcome can diverge sharply. SentinelOne's multiple of 1.37 times the starting investment against Zscaler's 0.7 times illustrates how much stock selection mattered relative to simply owning the space.
