Snowflake (NYSE: SNOW) shares surged approximately 98% over three months, rising from $142.56 to $282.90, while the S&P 500 returned just 2.5% over the same period.
Major cloud peers moved in the opposite direction during that window, with Microsoft falling 8.8%, Amazon dropping 12.7%, and Alphabet slipping 3.7%.
The rally was anchored in a single fiscal quarter report that fundamentally changed how investors understood the company’s growth trajectory.
At the fiscal Q1 2027 report in late May, product revenue came in at $1.334 billion, with year-over-year growth accelerating to 34%, up from 30% in fiscal Q4 2026 and 26% a year earlier.
Net revenue retention rose to 126%, and non-GAAP operating margin expanded more than 300 basis points year over year to reach 12%.
Management lifted the fiscal 2027 product revenue guidance to $5.84 billion, representing 31% growth, compared to the prior forecast of 27%, while raising the full-year non-GAAP operating margin guide from 12.5% to 13.5%.
By the company’s own explanation, the largest single driver of that guidance raise was Cortex Code, its AI-powered coding agent.
The critical detail is that three months earlier, at the fiscal Q4 2026 report in late February, management explicitly acknowledged that Cortex Code could not be included in their forecast at all.
The guidance methodology is built from observed consumption behavior, and Cortex Code had only reached general availability weeks before that February report, leaving no usable consumption data to model.
At the time, Cortex Code already had more than 4,400 customers, yet management stated that significant upside was sitting outside the number it had just published.
The broader AI adoption trend at Snowflake was not hidden in the quarters leading up to the surge, and had been disclosed incrementally each reporting period.
At the fiscal Q3 2026 report, Snowflake’s AI business crossed a $100 million revenue run rate a full quarter earlier than the company had anticipated, and AI influenced 50% of bookings signed in that quarter.
By fiscal Q4 2026, accounts using Snowflake Intelligence had grown to more than 2,500, nearly doubling quarter over quarter from earlier in the year.
Remaining performance obligations were growing 42% year over year as of fiscal Q4 2026, accelerating for a second straight quarter and outpacing the 30% product revenue growth reported in the same period.
Snowflake Intelligence and Cortex Code appeared together in a company announcement just one week before the stock’s run began, offering a visible pre-surge signal to attentive observers.
Options markets in the weeks before the rally showed implied volatility sitting at the 88th percentile of its trailing one-year range in mid-March, rising to the 95th percentile by mid-April at a reading of 61.2.
Elevated implied volatility indicated that options were priced for a large move in either direction, but gave no directional guidance on its own.
Heading into the run, trailing twelve-month revenue stood at $4.68 billion, up 29%, while the trailing twelve-month reported operating margin of -31% reflected a materially narrower loss than the three-year average of -38%.
The acceleration in the business was showing up in bookings and product adoption metrics before it appeared in total revenue, making it legible but not simple to act on with conviction.
Identifying the signal was arguably the straightforward part, while sizing a position in a company still reporting significant operating losses presented a much harder judgment call.
The stock now trades at $282.90, the top of its trailing 52-week range, representing a fundamentally different risk-reward setup than existed at the $142.56 entry point three months ago.
