Seagate Is Down 28%. What History Says About STX

Seagate Is Down 28% in 65 Days. What History Suggests

Seagate Technology Holdings plc (STX) is now down 28% from its all-time high as of September 16, 2026, having just exited the red zone after 65 days in drawdown. The Drawdown Severity Score™ has improved to 4.9, placing the stock in the Significant (yellow) zone. Historically, STX has dropped 25% or more only 10 times in its history, with those comparable drawdowns lasting an average of 655 days before full recovery.

The Shift From the Red Zone to the Yellow Zone

Our data shows that as of September 16, 2026, STX has transitioned from the red zone into the yellow zone, indicating a transition from severe drawdown conditions to a significant but stabilizing correction phase. This movement is defined by the asset's Drawdown Severity Score™ improving to 4.9. The change reflects a modest recovery in price from the lowest points of the current correction, though a substantial gap remains relative to the peak.

We define the red zone as a phase of extreme drawdown distress where the asset experiences rapid downward velocity and deep price disconnection. The transition to the yellow zone indicates that the immediate downward momentum has paused or partially reversed. However, the severity score of 4.9 still indicates that the asset remains in a historically deep correction.

Our database tracks these zone shifts to help investors understand when an asset is stabilizing. The transition from red to yellow is a major milestone in the life cycle of a drawdown, but it does not mean the correction is over. The asset must continue to reclaim key price levels to move into the green zone.

Deconstructing the Current 65-Day Drawdown

To understand the scale of the current movement, we must look at the exact pricing boundaries. The all-time high for STX stands at $1094.04. As of September 16, 2026, the current price is $783.18, representing an exact drawdown of -28.4% from that peak.

This means the stock has lost $310.86 per share from its highest historical valuation point. The duration of this drawdown has reached 65 days. When we compare this to the historical baseline of the asset, we see a clear divergence.

The current 65-day drawdown has already exceeded the historical average duration of 61 days for all drawdowns in our database. The Drawdown Severity Score™ of 4.9 reflects this extended duration combined with a depth that is far more severe than normal pullbacks. A normal drawdown of -7.7% from the peak of $1094.04 would represent a drop of only $84.24, which is far less severe than the current $310.86 drop.

The velocity of this decline is also a key factor in the severity score calculation. Dropping -28.4% in just 65 days represents a rapid destruction of peak value. This high velocity is a primary reason why the severity score was pushed deep into the red zone during the early weeks of the decline. Now that the price has stabilized near $783.18, the velocity has slowed, allowing the severity score to improve to 4.9.

Valuation Context and Historical Multiples

Contrasting this price decline, a valuation snapshot as of 2026-09-13 shows that the stock's valuation multiples remain elevated relative to its own historical range. The Price-to-Sales ratio (P/S) was 14.4, which sits in the 98th percentile of its own daily P/S record since 2006-09-11, compared to a historical median of 1.2. Similarly, the EV-to-EBITDA ratio (EV/EBITDA) was 40.7, placing it in the 94th percentile of its daily record since 2006-09-11, compared to its historical median of 8.4.

Historical Drawdown Events and Comparable Drops

Evaluating the current correction requires comparing it to the complete historical record of STX. Our data shows that the average maximum drawdown across all 137 historical drawdown events is -7.7%. The current drawdown of -28.4% is more than three times as deep as the historical average.

To provide a clearer picture of how this drawdown ranks, we can compare the current metrics to the historical averages in a structured format. This comparison highlights the unique scale of the current market cycle for STX.

This table shows that while the duration is only slightly above the historical average, the depth is highly anomalous. The severity score of 4.9 accounts for this imbalance by weighting both the velocity and the absolute depth of the decline.

Analysis of 25% Plus Drawdown Cycles

While minor pullbacks are common, deep drawdowns of 25% or more are relatively rare for STX. Our historical data shows that STX has dropped 25% or more from an all-time high only 10 times in its history. These 10 events represent the most severe corrections the company's historical record has experienced.

The average duration of these 10 comparable drops is 655 days. This duration measures the total time from the initial peak to the complete recovery of the previous all-time high. Comparing the current 65-day duration to this 655-day historical average reveals that the current cycle is still in its very early stages.

If the current correction follows the historical pattern of these 10 prior deep drops, the recovery process could be highly extended. The Drawdown Severity Score™ will continue to track whether STX can break from this historical pattern or if it will require a multi-year period to reclaim its peak of $1094.04.

Out of 137 total drawdown events, only 10, or 7.3%, have reached a depth of 25% or more. This highlights how unusual the current -28.4% drawdown is. The average duration of 655 days for these 10 events means that once STX crosses the 25% threshold, the path back to the previous peak has historically been a long, multi-month or multi-year process. As of September 16, 2026, STX is at just 9.9% of the average duration of those historical 25% plus drawdown cycles.

Data Methodology and Analytical Limits

Our analysis relies strictly on historical price and drawdown data recorded in our database. We do not incorporate external market narratives, corporate earnings reports, or broader macroeconomic indicators into this evaluation. This content is designed to provide purely quantitative context based on past price behavior.

Historical performance does not guarantee future results, and prior drawdown patterns may not predict how the current cycle resolves. By focusing exclusively on mathematical relationships between price, peak, and duration, we aim to offer an objective framework for assessing risk.

Our database tracks 137 historical drawdown events for STX, providing a robust statistical baseline. However, every market cycle contains unique variables that price data alone cannot capture. This analysis is limited to the mathematical historical record and does not constitute financial advice.

Key Thresholds and Metrics to Watch

To monitor the progress of STX as it navigates the yellow zone, several key quantitative milestones should be watched. A further price recovery that reduces the drawdown to less than 20% would signal a transition toward the next severity zone. Conversely, a drop back below the current price of $783.18 would increase the severity score and potentially push the stock back into the red zone.

Specifically, a decline that exceeds the current -28.4% mark would mark a new low for this cycle and increase the severity score toward the extreme risk category. We will continue to monitor these metrics daily as the drawdown progresses.

To reduce the drawdown to -20%, the price would need to rise to $875.23, which represents an 11.8% increase from the current price of $783.18. To reduce the drawdown to -10%, the price would need to rise to $984.64. To reach a new all-time high, the price must rise above $1094.04, requiring a gain of 39.7% from the current price of $783.18.

If the price drops back to $711.13, that would represent a -35% drawdown, likely pushing the asset back into the red zone and worsening the Drawdown Severity Score™. Monitoring these exact price levels helps investors track the asset's progress relative to historical boundaries.
