Amkor Is Down 13%. What History Says About AMKR Now

Amkor Is Down 13% in 30 Days. What Our Data Shows

As of June 8, 2026, Amkor Technology, Inc. (AMKR) has transitioned from the yellow zone to the green zone as its drawdown measures -12.6% from its all-time high of $78.10. This transition is marked by a Drawdown Severity Score™ of 1.8, reflecting a shift from a higher risk state to a slightly elevated level. The stock has spent 30 days in this drawdown period, trading at a price of $68.29 as of June 8, 2026.

Understanding the Zone Transition

The transition from the yellow zone to the green zone indicates a statistical cooling of risk according to our proprietary metrics. As of June 8, 2026, the Drawdown Severity Score™ of 1.8 places the stock in the "Slightly Elevated" category. This movement represents a decline in the velocity and depth of the stock's retreat relative to its historical patterns.

The stock reached its all-time high of $78.10 before entering the active drawdown 30 days ago. The recovery to a price of $68.29 has narrowed the total drawdown to -12.6%. Our data shows that this shift represents a stabilization compared to the deeper risk territory the stock occupied while in the yellow zone.

A Drawdown Severity Score™ of 1.8 indicates that the asset is experiencing a standard pullback rather than a severe structural decline. The green zone classification suggests that the selling pressure has moderated, bringing the asset back within normal historical parameters. Our historical data shows that remaining in the green zone typically correlates with lower short-term volatility compared to periods spent in the yellow or red zones.

Historical Drawdown Context for Amkor Technology

To evaluate the significance of a -12.6% drawdown lasting 30 days, we examine the historical performance of the stock. Over the lifetime of our tracking data, we have recorded a total of 17 historical drawdown events for this asset. These events provide a baseline for measuring the severity and duration of the asset's price contractions.

The historical average maximum drawdown for the stock is -18.4%. The average duration of all recorded drawdowns is 38 days. Comparing the active drawdown of -12.6% to these historical averages reveals that the active 30-day drawdown is shallower than the historical average depth, though it is approaching the average duration of 38 days.

Our data shows that a drawdown of this depth is a frequent occurrence for this asset. The historical baseline suggests that the stock often experiences corrections of this scale during normal market cycles. The Drawdown Severity Score™ of 1.8 reflects this alignment with historical norms, indicating that the current contraction does not represent an extreme outlier.

Deep Dive: The 15% Severity Threshold

While the active drawdown stands at -12.6% as of June 8, 2026, our historical database tracks deeper thresholds to evaluate tail risk. Specifically, we look at instances where the stock has dropped by 15% or more from its peak. This threshold serves as a critical separator between minor pullbacks and prolonged corrections.

Our database shows that the stock has dropped 15% or more a total of 4 times. When the stock crosses this 15% threshold, the recovery timeline extends significantly. The average duration of these comparable drops of 15% or more is 135 days.

It is important to note the small sample size for these deeper events, as only 4 events meet this criterion. This small sample size means that historical averages for deeper drops may be subject to high variance and should be interpreted with caution. However, the contrast between the general average duration of 38 days and the 15% threshold average of 135 days highlights how risk dynamics change when a drawdown deepens past the 15% level.

The historical data indicates that once the stock breaches the 15% threshold, the time required to recover its peak increases by more than three times. This historical pattern underscores the importance of the current stabilization at -12.6%. The transition to the green zone suggests that the stock is resisting a move into this deeper, more prolonged drawdown territory.

Comparing Drawdown Metrics

To provide a clear view of how the active drawdown compares to historical benchmarks, we have structured the key metrics in the table below. This table contrasts the active drawdown state as of June 8, 2026, against the historical averages for all drawdowns and the subset of deeper drawdowns.

| Metric | Active Drawdown (As of June 8, 2026) | Historical Average (All Events) | Deep Drawdown Average (15%+ Drops) | | :--- | :--- | :--- | :--- | | Drawdown Depth | -12.6% | -18.4% | -15.0% or greater | | Duration in Days | 30 days | 38 days | 135 days | | Total Events | 1 (Active) | 17 events | 4 events | | Drawdown Severity Score™ | 1.8 (Slightly Elevated) | N/A | N/A |

This comparison shows that the active drawdown is shorter and shallower than the average historical drawdown. The active 30-day duration is close to the historical average of 38 days, while the current depth of -12.6% remains 5.8 percentage points above the average historical bottom of -18.4%.

The table also highlights the substantial gap between a standard drawdown and a deep drawdown. While the typical pullback resolves in 38 days, a drop exceeding 15% has historically required 135 days to resolve. The current position of the stock sits between these two historical regimes.

Methodology and Data Limits

This drawdown analysis relies strictly on historical price data, peak-to-trough calculations, and the proprietary Drawdown Severity Score™ model. We do not incorporate external market narratives, company earnings reports, macroeconomic indicators, or qualitative analyst ratings into this evaluation.

Our model operates on the principle that price movement history and drawdown duration provide an objective framework for risk assessment. By focusing purely on quantitative metrics, we eliminate subjective bias from the analysis. This approach allows investors to assess risk based on actual historical behaviors rather than speculative forecasts.

Investors should note that past performance and historical drawdown patterns do not guarantee future price action. The historical averages presented, particularly the 4 instances of 15% or deeper drawdowns, represent a limited historical record. This analysis does not make predictions about whether the stock will return to its all-time high or experience further downward pressure.

Key Levels and Severity Thresholds to Monitor

As of June 8, 2026, several key price levels and drawdown thresholds will dictate the future risk classification of the stock. Monitoring these levels allows for an objective assessment of whether the risk profile is stabilizing or deteriorating.

First, the 15% drawdown threshold sits at a price of $66.39. A drop to or below this price would mark a transition into the deeper historical drawdown category. Historically, crossing this threshold has extended the average recovery time to 135 days, based on the 4 comparable events in our database.

Second, the historical average maximum drawdown of -18.4% corresponds to a price of $63.73. If the active drawdown deepens to this level, it would align the current cycle with the average historical correction depth for this asset.

Third, a return to the all-time high of $78.10 would represent a full recovery and reset the drawdown days to zero. The Drawdown Severity Score™ of 1.8 indicates that the asset is in a lower-risk green zone as of June 8, 2026, but any downward price movement toward the $66.39 level would likely trigger a transition back into the yellow zone or a higher severity category.
