Advanced Energy Industries, Inc. (AEIS) has declined 16.9% from its all-time high of $389.05, reaching a current price of $323.46 as of May 16, 2026. This move has pushed the stock out of its previous green zone and into the yellow zone, signaling a shift in the risk profile for this asset. This specific drawdown has materialized over a 10-day period, representing a rapid departure from its peak valuation.

Understanding the Current Drawdown Severity Score™

Our data shows that the Drawdown Severity Score™ for Advanced Energy Industries, Inc. (AEIS) is currently 2.6. This score is classified as Moderately Elevated, which is why the stock has transitioned into the yellow zone. A score of 2.6 indicates that while the current 16.9% decline is significant, it is viewed within the context of the stock's total historical volatility and previous price behavior.

The transition from the green zone to the yellow zone is a data-driven marker that the current sell-off is exceeding standard "noise" levels. In the history of this stock, we have tracked a total of 63 historical drawdown events. The current 16.9% decline has already surpassed the average maximum drawdown of -11.4% recorded across those 63 events. Because the stock is now falling further than its historical average, the Drawdown Severity Score™ has adjusted to reflect increased risk.

Historical Context and Comparable Declines

When analyzing the history of Advanced Energy Industries, Inc. (AEIS), we look for patterns in how the stock behaves once it reaches specific levels of distress. Our data indicates that AEIS has experienced 4 instances where the drawdown reached or exceeded the 60% threshold. While the current 16.9% drop is far from those extreme levels, these historical markers provide a ceiling for what the stock is capable of experiencing during major market cycles.

In those 4 specific instances where the stock dropped by 60% or more, the average duration to reach a full recovery was 2135 days. It is important to note that this represents a very small sample size of only 4 events, which can skew historical averages. However, these data points serve as a reminder that deep drawdowns for this ticker have historically required years, not months, to resolve.

The current drawdown duration of 10 days is exceptionally short compared to the average drawdown duration for this stock, which stands at 174 days. Historically, AEIS pullbacks tend to be prolonged processes. The fact that the stock has reached a 16.9% decline in just 10 days suggests a higher velocity of selling than what is typically seen in its average 174-day drawdown cycle.

Data Limits and Analysis Framework

This analysis of Advanced Energy Industries, Inc. (AEIS) is based strictly on price and drawdown history. We rely on the relationship between the current price of $323.46 and the all-time high of $389.05 to determine the current state of risk. Our Drawdown Severity Score™ does not take into account external factors, corporate earnings, or broader economic narratives.

By focusing solely on the proprietary Drawdown Severity Score™ and historical duration data, we provide a quantitative view of how the current price action compares to the last 63 drawdown events. This allows investors to see the current 16.9% drop through the lens of historical probability rather than sentiment. We do not make claims about why the stock is moving, only where it stands relative to its own historical volatility.

What to Watch in the AEIS Drawdown

As Advanced Energy Industries, Inc. (AEIS) continues its time in the yellow zone, there are several data-driven markers we are monitoring. The first is the duration of the current move. At 10 days, the stock is still in the very early stages of a drawdown compared to its historical average of 174 days. If the drawdown persists without a recovery, the Drawdown Severity Score™ will continue to update to reflect the increasing duration risk.

The second factor is the depth of the drawdown. Having already passed the average max drawdown of -11.4%, the next major historical markers are the rare 60% declines. While the stock is currently at -16.9%, any further movement toward the 20% or 30% range would likely result in a higher severity score. We will continue to track whether the current price of $323.46 holds or if the stock moves deeper into the yellow zone.

Monitoring the Drawdown Severity Score™ allows for a disciplined approach to risk. If the score begins to trend back toward the green zone, it would indicate that the price is stabilizing or recovering relative to its peak. Conversely, an increase in the score would suggest that the current 10-day sell-off is becoming an outlier compared to the 63 previous events we have recorded for this ticker.
