The Investor Day and Guidance

At its October 6, 2026 investor day Zscaler (NASDAQ:ZS) reaffirmed guidance and set out a long-term path toward USD 8 billion of annual recurring revenue, with a higher case tied to artificial intelligence adoption. TD Cowen raised its target to USD 230 from USD 200 afterward, and other firms also lifted targets. Fiscal 2026, which ended July 31, brought revenue of USD 3.35 billion, about 20% growth excluding the Red Canary acquisition, and an operating loss that narrowed to 0.4% of revenue in the fourth quarter. Guided growth slows to under 18%, so the market is paying for durability. Zscaler sells security delivered through its cloud, so growth depends on large customers adding seats and products such as data protection.

Software Rebound and Valuation

The stock also rode a broad software recovery. The software ETF rose 2.81% on October 9, 2026 with Zscaler among the day's leaders at about 7.8%, and a J.P. Morgan note dated October 8 said the group had gained about 21% since June on estimate upgrades. On October 21 the shares rose 7.8% again as DA Davidson started coverage at Neutral with a USD 215 target. Published data put the stock at 11.2 times trailing sales that day, against 6.8 times at the end of June, so much of the gain is a higher multiple. A higher multiple means investors accept lower near-term returns for faster growth, which makes the shares more sensitive to changes in interest rates and to any slowdown in bookings.

Risks and What to Watch

At USD 262.38 the price is about 22% above DA Davidson's USD 215 target, simple arithmetic, which shows how far sentiment has run ahead of some analysts. Net losses on a GAAP basis, high memory costs that keep capital spending elevated, competition from larger platforms and a possible software pullback are the main risks. The next quarterly report is expected in November 2026, and revenue against the guided range is the key test. This is not advice. Management also warned that memory costs are keeping capital spending high in fiscal 2027, which can weigh on free cash flow growth. The stock fell sharply earlier in 2026 on fears about artificial intelligence labs entering applications, and a return of that worry could reverse the rebound quickly.

Where Things Stand

The answer is that the October 6, 2026 investor day, steady guidance and a wide software rebound explain the month, and a higher valuation multiple supplied much of the gain. Zscaler (NASDAQ:ZS) is up 38.90% in a month and 22.32% in a week, now above DA Davidson's USD 215 target. The November report will show whether growth near 17% justifies the multiple. Analyst targets will likely be revisited after the report.
