# ZS (Zscaler) Research Report — May 18, 2026
**Verdict: BULLISH (6/10 conviction)**
—
## 1. What Happened
Google Trends spike (+33%) is driven by three converging catalysts: (a) a sector-wide cybersecurity rally ignited by Fortinet’s blowout earnings, lifting PANW +5.4%, CRWD +7%, and ZS ~17% over 7 days; (b) pre-earnings positioning ahead of ZS Q3 FY2026 results on **May 26** (after close); (c) a fresh wave of high-profile breaches (Itron, Medtronic/ShinyHunters, SharePoint zero-day CVE-2026-32201) reinforcing the cybersecurity spending narrative. No ZS-specific breach, deal, or product launch is responsible — this is sector momentum plus earnings anticipation.
## 2. Recent News & Sentiment (Last 7 Days)
– **+17% in 7 days**, +10% in a single session (May 14). Stock at ~$154, still down 54% from Nov 2025 high of $336.
– **Raised FY2026 ARR guidance** to $3.73–3.745B (24% growth), up from prior 23% forecast.
– **Google Cloud Partner of the Year** for Security (Application category), announced April 21 at Google Cloud Next.
– Analyst consensus: **Buy**, average PT $223–261 (44–69% upside from current).
– Fortinet’s earnings sparked the sector rotation; traders now front-running ZS’s May 26 print.
## 3. Key Financial Metrics
| Metric | Value |
|—|—|
| Price | ~$154.40 |
| Market Cap | $22.3B |
| 52-Week High / Low | $336 / ~$125 |
| FY2025 Revenue | $2.67B (+23% YoY) |
| ARR Guidance (FY2026) | $3.73–3.745B (+24%) |
| Net Loss (FY2025) | -$41.5M (improving, -28% vs FY2024) |
| Forward P/S | ~6x (compressed from 15x+ at peak) |
## 4. Competitive Landscape
– **Fortinet**: Cheapest quality name (30x forward, 80% gross margins, 28.6% net margins). Set the tone for the sector rally.
– **CrowdStrike**: $5.25B ARR, 24% growth, GAAP profitable, guiding FY27 revenue to $5.9B. Premium valuation justified.
– **Palo Alto**: Soaring alongside CRWD; platformization strategy gaining traction.
– **ZS positioning**: Most valuation-compressed of the group (down 54% from peak despite 24% ARR growth). If Q3 beats, mean-reversion trade has significant upside. Zero trust / SASE is a structural tailwind.
## 5. Risk Factors
1. **Earnings binary event in 8 days (May 26)**. Any miss or weak guidance will reverse the rally violently given the run-up.
2. **Still GAAP unprofitable**. Losses narrowing but not yet crossed to positive.
3. **Revenue growth decelerating** (23% in FY2025 vs 34% in FY2024). Market watching for re-acceleration signals.
4. **Sector crowding risk**. CIBR saw $30M in 5-day inflows; if the trade unwinds post-earnings, selling pressure will be amplified.
5. **Macro headwinds**. Stock down 30% YTD; broader IT budget pressure persists despite cyber resilience.
## 6. Cybersecurity ETF Flows
– **CIBR**: +$30.3M 5-day inflows, +$7.8M 1-month. Positive but not euphoric.
– **HACK**: +$4.2M 5-day, but -$18.8M 1-month, -$134M 6-month outflows. HACK losing assets to CIBR structurally.
– **Read**: Sector rotation is real but measured — not a flood. Supports a sustained move rather than a blow-off top.
## 7. Conclusion
**BULLISH (6/10 conviction).** The setup is attractive: massive valuation compression (6x forward P/S vs 15x+ historical), accelerating ARR (24%), sector tailwinds from Fortinet’s beat, and fresh breach catalysts. The Google Trends spike reflects legitimate pre-earnings positioning, not noise.
The cap on conviction: earnings in 8 days is a binary event, and the stock has already run 17% into it. A miss would be painful. For a swing trade, the risk/reward favors entry with a tight stop below $140. For a longer-term position, waiting for a post-earnings dip (if guidance disappoints) offers better entry. Analyst targets of $223–261 imply 44–69% upside if the growth story holds.
**Key date: May 26 after close — Q3 FY2026 earnings.**
