The full-chain put/call ratio on Zscaler (NASDAQ:ZS) sits at 0.64, a call-heavy skew that fits with today’s 3.91% pre-earnings rally to $179.48. Front-week contracts expiring September 4 show a ratio of 0.66, suggesting traders are leaning long into the event.
The October 23 expiration prints a ratio of 8.31, and February 2027 spikes to 28.15, pointing to sizable protective put positioning or hedged institutional bets.
History urges caution: the last three reports produced day-of drops of -31.52%, -12.17%, and -13.03% despite beats. One-week reactions were kinder, with Q2 FY26 rebounding 11.61% and Q3 FY26 recovering 6.3%.
Bottom line: options lean bullish, but overnight gap risk is real.
