Zscaler shorts edge up as options turn cautious before November print

Zscaler fell 6.2% over the past week to $214.51, a move almost exactly in line with its closest cybersecurity peers. CrowdStrike dropped 13% over the same stretch, Fortinet lost 10.4%, and SentinelOne fell 8.4%, so the week's selloff looks more like a sector rotation than a company-specific story. The stock has recovered 8.7% over the past month, which means most of the damage is recent.

Options positioning has tilted more defensive than usual into the November 25 earnings date. The put/call ratio moved to 0.84, more than two standard deviations above its 20-day average of 0.80. That is the most protective options setup seen on this name in recent weeks, though it is still well below the 52-week high of 1.07. The shift is modest but consistent: the PCR has drifted upward every session since October 12, suggesting the caution is building gradually rather than representing a sudden hedge.

Short interest tells a more relaxed story. Bears hold roughly 3.7% of the free float, a position that has actually shrunk about 9% over the past month even as it ticked up 1.9% this week. Borrowing costs are low, around 0.29%, and availability is extremely loose with over 100 million shares available to lend. There is no meaningful squeeze pressure and no sign that the incremental short-selling this week reflects a new conviction thesis rather than tactical hedging.

The Street remains broadly constructive but has just hit the brakes in a small way. A clutch of analysts lifted targets in early October following the fiscal-year results, with UBS, Citigroup, Jefferies and Macquarie all raising to the $250 range. Then on October 21, DA Davidson started coverage at Neutral with a $215 target, exactly where the stock is trading now. That initiation is worth noting: the new entry point implies the positive revisions that followed the FY26 print have already been absorbed by the price. The consensus mean target of $233 still represents roughly 9% upside from current levels, and Citigroup raised its target again this week to $260, maintaining Buy. EPS revisions are strong, ranking in the 93rd percentile on a 12-month forward basis, but the EPS surprise score is low at the 19th percentile, a reminder that Zscaler has not consistently beaten the elevated bar its valuation demands.

The fundamental picture the bulls are defending is substantial. FY26 ARR reached $2.8 billion on an 18% three-year growth rate, with revenue up 25% and free cash flow margins at 23%. Management guided FY27 ARR to $4.4 billion and revenue to $3.9 billion, and the bear case is less about the core business deteriorating than about the pace of enterprise migration away from hardware appliances and the risk that hyperscalers price more aggressively into the cloud security market. At a PE of 39 and an EV/EBITDA of 25, the stock prices in continued execution without much room for a miss.

On the ownership register, the most notable development is older but still relevant: Vanguard filed a 13G/A in March indicating it had exited its 7.2% stake entirely. BlackRock filed in July disclosing a 5.1% position. The top two holders remain co-founder Jagtar Chaudhry at 16.5% and Ajay Mangal at 17.8%. Insider activity this week consisted entirely of equity awards to the CFO, CLO and CPO, standard compensation grants with no open-market significance. Earlier sales by the Chief Product Officer in October were all executed under a pre-arranged 10b5-1 plan.

The next scheduled earnings date is November 25. The two most recent post-earnings moves were plus 5.8% one day after the October 2026 print and minus 1.7% after September 2026, so the stock's reaction has not been consistent. What the November print is likely to be judged on is whether early AI monetisation, cited by management as generating roughly $70 million in ARR, is accelerating and whether the $15-billion-plus of expansion potential inside existing customers is translating into measurable net revenue retention improvement.
