What is the Drawdown Severity Score™?

Current Drawdown Duration and Depth

The current price of $182.37 reflects a substantial departure from historical price peaks for the cybersecurity firm. Our data shows that Zscaler, Inc. (ZS) has spent 1,581 days in this specific drawdown cycle as of May 22, 2026. This duration is exceptionally long when compared to the average drawdown duration of 26 days for this ticker across its entire trading history.

The depth of the current decline, at 50.5%, also stands in stark contrast to the historical average max drawdown of 7.6% across all 48 historical drawdown events recorded by our platform.

Historical Context for Large Declines

In the history of Zscaler, Inc. (ZS), declines of 30% or more are relatively rare. Our data shows that this has occurred only 2 times prior to the current environment. Because this is a small sample size, investors should weigh these historical averages with caution.

The average duration of these comparable drops, where the stock fell by at least 30%, is 232 days. The current cycle of 1,581 days has already exceeded that historical average by more than sixfold. This suggests that the current price action is an outlier in the stock's historical behavior. Our data shows that the last time a drawdown reached this level of severity, the recovery timeline was significantly shorter than what we are observing in the current market as of May 22, 2026.

Understanding the Severity Score™ Red Zone

The red zone designation for Zscaler, Inc. (ZS) is driven by the combination of the total percentage lost from the peak and the time elapsed without reclaiming those highs. A Drawdown Severity Score™ of 8.7 indicates that the stock is experiencing one of the most severe periods of price depression in its history.

We categorize assets in the red zone when the risk of further stagnation or continued volatility is statistically higher based on historical price patterns. For Zscaler, Inc. (ZS), the severity score has remained in this zone despite the stock trading at $182.37. To move out of the red zone, the stock would need to significantly narrow the 50.5% gap between its current price and the all-time high of $368.78.

Data Limits and Analysis Framework

Our analysis of Zscaler, Inc. (ZS) is based strictly on price action, drawdown depth, and historical duration metrics. We do not incorporate fundamental earnings data, industry trends, or broader macroeconomic events into this specific assessment. The Drawdown Severity Score™ is a proprietary calculation that measures the intensity of a sell-off relative to an asset's own historical volatility and recovery patterns.

By focusing exclusively on the drawdown data, we provide a clear view of the stock's current risk state without the influence of market sentiment or external narratives. This data-only approach allows investors to see exactly where the stock sits in its historical lifecycle as of May 22, 2026.

What to Watch in the Data

For the data profile of Zscaler, Inc. (ZS) to change, we would look for a reduction in the severity score. A move from a score of 8.7 toward a lower threshold would indicate that the stock is beginning to reclaim lost ground or that the volatility of the drawdown is stabilizing.

The most critical level to monitor is the 50.5% drawdown mark. If the stock continues to trade below $182.37, the duration of 1,581 days will continue to climb, further increasing the Drawdown Severity Score™. Conversely, a sustained move toward the all-time high would begin the process of a zone transition, though the stock remains deep within the red zone for the time being.
