Zscaler has now moved 17% higher in a month and short sellers have mostly stepped aside — but options traders are quietly loading up on downside protection as the September earnings date comes into view.
The options signal is the week's most interesting wrinkle. The put/call ratio climbed to 0.78 on Tuesday, nearly two standard deviations above its 20-day average of 0.71 — the most defensive reading in options positioning in several weeks. That move stands out precisely because it cuts against the broader bullish tape: the stock jumped 7.2% on Monday alone and the lending market remains almost frictionless, with availability at 4,033%, meaning roughly forty shares sit available for every one currently borrowed. Shorts that covered through early July did so cheaply and easily — cost to borrow barely registers at 0.44%, up only modestly from a month ago. The short score has also reset sharply lower, dropping from 48 in late June to 40.7 now, confirming that the pressure on shorts has materially eased rather than simply paused.
What puts that options defensiveness in context is the earnings calendar. The next print is scheduled for September 1. Zscaler's last two reports produced wildly asymmetric outcomes: a 19.7% gap higher in May 2026 on strong Q3 billings, followed immediately by a 30.7% single-day collapse on what appears to have been a subsequent revision event in late May. That kind of volatility — nearly 31 points down then 20 points up inside a month — gives options traders genuine reason to hedge early. The put/call z-score close to 2.0 suggests that hedging is exactly what's happening.
The Street remains broadly constructive, though with some fine-tuning at the margin. 30 analysts carry buy-equivalent ratings, with consensus targets clustering in the $172–$225 range. Keybanc trimmed its target to $176 from $190 in late June, a modest negative revision, while Wedbush and Cantor Fitzgerald are anchored at $220–$225, well above the current price of $152. The gap between consensus at $192 and the current price implies roughly 27% upside, which helps explain why the analyst community held its ratings even after May's sharp move lower. The bull case rests on zero-trust platform momentum, AI-driven cybersecurity spend, and improving operating leverage. The bear case centres on customer retention friction, governance concerns around AI tools, and near-term revenue growth deceleration.
Among close peers, the session Monday was broad-based but ZS was not the standout. CRWD jumped 12.1% and NTSK surged 11.5% on the day, with S adding 7.4% — essentially matching ZS's move. The week-to-date picture tells a similar story: NTSK led the group at +18.4% while ZS's 1.7% weekly gain was more modest, suggesting the Monday pop recouped earlier-week softness rather than representing an isolated breakout.
What to watch from here is whether the PCR remains elevated as the stock consolidates above $150, and whether any analyst recalibrates targets in response to the July price move — the next meaningful data point being the September 1 earnings release, where the stock's recent history suggests the market will be positioned for a wide range of outcomes.
