Zscaler, Inc. (ZS): fair value, margin of safety and Wheel Score
Technology · Software - Infrastructure · United States · Speculative / Distressed
Is ZS undervalued?
Zscaler, Inc. (ZS) closed at 220.79 on 16 Oct 2026, 110% above the GLS average fair value of 105.30. 2 of the 2 models that produced a number value the shares below the current price. A gap this wide usually means the market is paying for growth or a story the trailing numbers do not show yet; the models work from filed results, not forecasts, so they are conservative by design.
The average is built from just 2 models (DCF, 10 Cap) - the rest returned nothing because an input they need (dividends, free cash flow, book value) is zero or negative - so treat it with more caution than usual.
The nightly engine files ZS under Speculative / Distressed - negative earnings or a Piotroski score of 3 or less - which caps its Wheel Score at 45 and keeps it out of the Sunday Scan.
Nine valuation models for ZS
Each model turns the latest filed numbers into a value per share; the GLS fair value is the simple average of the ones that produce a positive number. The last two rows are shown for reference and never enter the average. The Quote page lets you switch any model off and add your own margin of safety.

Quality and financial health
Zscaler, Inc. scores only 4 of 9 on the Piotroski F-score, which fails the Sunday Scan's "6 or more" rule. A reading this low means several of the basic tests - positive earnings, positive operating cash flow, falling debt, no new share issuance - are not met. On durability ZS scores 6.0/10 on the GLS Moat - a middle reading; the Scorecard on the Quote page's Financials tab shows which ten-year lines are steady and which are not.
Returns on capital are thin or negative - ROIC -1.4%, ROE -2.4%, ROA -0.8% - with debt at 0.71 times equity and a free-cash-flow yield of 2.4%.
Zscaler, Inc. pays no dividend, so the DDM model does not apply and a covered-call holder earns only the premium and any price gain. Revenue comes mainly from Reportable 100% (quarter Q4 FY2026).
Institutional ownership scores 6/10, insider activity 2/10 and Congressional trading 5/10 on the GLS smart-money scales; the last recorded insider buy was on 15 Sep 2026.
| Piotroski F-score | 4 / 9 | ROIC | -1.4% |
|---|---|---|---|
| GLS Moat | 6.0 / 10 | ROE | -2.4% |
| Debt / equity | 0.71 | ROA | -0.8% |
| Free-cash-flow yield | 2.4% | Payout ratio | 0% |
| Institutions | 6 / 10 | Insiders · Congress | 2 · 5 / 10 |
Wheel Score 45: Weak
With a Wheel Score of 45 Zscaler, Inc. sits in the Weak band, capped at 45 because the engine files it as Speculative / Distressed. The parts - Value 0/25, Health 9/20, Moat 9/15, Premium 19/20, Stability 20/20 - show where: Value (0/25) scores lowest.
Implied volatility is 66% on the near-the-money contracts 20-60 days out - above the 60% ceiling of the sweet spot. Premiums are large, but the Wheel Score tapers the Premium points (19 of 20) because volatility this high usually comes with a reason. The option chain is deep: 173,371 contracts of open interest across all expiries, which means tight fills at most strikes.
Volume runs at 2.9M shares a day on a market cap of $35.7B, with a beta of 0.94; the Stability part of the Wheel Score gives that 20 of 20.
| Part | Points | From | |
|---|---|---|---|
| Value | 0 / 25 | -110% margin of safety | |
| Health | 9 / 20 | Piotroski 4/9 | |
| Moat | 9 / 15 | moat 6.0/10 | |
| Premium | 19 / 20 | implied volatility 66% | |
| Stability | 20 / 20 | 2.9M shares/day, $35.7B cap, beta 0.94 |
