Amkor Technology Is Down 15%. What History Says Now

Amkor Technology, Inc. (AMKR) has entered a new phase of price risk as of May 18, 2026, with its current drawdown reaching 15.4% over a 16-day period. Our data indicates that the stock has officially transitioned from the green zone into the yellow zone, signaling a meaningful shift in its short-term price stability. This move represents a departure from the relatively shallow volatility the asset experienced in the preceding weeks.

Understanding the Drawdown Severity Score™

The Drawdown Severity Score™ for Amkor Technology (AMKR) currently stands at 2.2. This specific score is categorized as Moderately Elevated, placing the stock firmly in our yellow zone. While the stock remains well above its historical average maximum drawdown of -18.4%, the speed of this 16-day decline has triggered a change in the internal risk profile we track.

Our data shows that a Drawdown Severity Score™ of 2.2 reflects a period where the current price of $66.04 is significantly detached from its all-time high of $78.10. In the context of the 17 total historical drawdown events we have recorded for this asset, a move into the yellow zone indicates that the current sell-off is no longer a minor fluctuation. It has reached a threshold where the historical probability of a quick "V-shaped" recovery begins to diverge from past performance patterns.

Historical Context of 15% Declines

To understand the current -15.4% drawdown, we must look at how Amkor Technology (AMKR) has behaved during similar contractions. According to our data, the stock has dropped 15% or more from a peak only 4 times in its recorded history. This is a relatively small sample size, which suggests that drawdowns of this specific magnitude are not frequent occurrences for this ticker.

When Amkor Technology (AMKR) hits this 15% drawdown threshold, the recovery process tends to extend significantly beyond the asset's general averages. While the average drawdown duration for all events is 38 days, the average duration of these 4 comparable drops is 135 days. This data point suggests that once the stock breaches the 15% mark, it historically spends nearly four times longer in a drawdown state before reclaiming its previous highs.

Data-Driven Risk Analysis

Our analysis of Amkor Technology (AMKR) relies exclusively on price action, drawdown depth, and duration metrics as of May 18, 2026. We do not incorporate external market narratives, sector trends, or fundamental shifts into this specific assessment. The focus remains entirely on the Drawdown Severity Score™ and how the current 16-day decline compares to the 17 historical drawdown events on record.

The current price of $66.04 represents a specific technical state where the asset is testing its historical norms. Because our data shows only 4 instances of a 15% decline, the statistical weight of these comparisons is limited. However, the exact numbers provided by our proprietary data highlight a clear trend: deeper drawdowns for this stock have historically required a much longer period of time to resolve than the more common, shallower pullbacks.

Monitoring the Recovery Path

As Amkor Technology (AMKR) navigates the yellow zone, there are specific data markers that will determine if the risk profile intensifies or stabilizes. The most immediate figure is the average max drawdown of -18.4%. If the current -15.4% drawdown continues to expand toward that -18.4% level, we would expect to see the Drawdown Severity Score™ increase accordingly, potentially signaling a move toward the red zone.

Conversely, the 16-day duration is currently well below the 38-day average for all drawdowns and significantly below the 135-day average for comparable 15% drops. We will continue to monitor whether the stock can break its historical trend of extended recoveries for this level of severity. Any movement in the current price of $66.04 will be reflected in real-time updates to the Drawdown Severity Score™, providing an objective measure of whether the risk is compounding or dissipating.
