Tower Semiconductor Is Down 47%. What History Says Now

Tower Semiconductor Has Dropped 47%. Here Is What History Says

As of June 22, 2026, Tower Semiconductor Ltd. (TSEM) remains in the red zone with a Drawdown Severity Score™ of 7.1, representing a -47.0% drawdown from its all-time high. This current price of $316.85 sits far below the historical peak of $598.13, marking a prolonged period of underperformance. Our data indicates that this asset has spent thousands of days attempting to recover its peak value, positioning the stock in a historically severe drawdown state.

The Anatomy of TSEM's 47.0% Drawdown

The current price of $316.85 represents a substantial retracement from the all-time high of $598.13. This -47.0% gap highlights the intense selling pressure the asset has faced over an extended period. The Drawdown Severity Score™ of 7.1 classifies this event as Very Strong, placing it firmly within the red zone.

Our data shows that the previous zone for this asset was also the red zone. This indicates that the stock has not experienced a meaningful recovery phase recently, instead consolidating or continuing its decline within this highly depressed territory. The prolonged stay in this zone suggests that the downward momentum has established a deep, long-term trend.

The scale of this decline is far outside the normal operating range for this stock. While minor pullbacks are common in equity markets, a near-halving of market value represents a major structural shift. Investors tracking this asset must consider the historical duration required to resolve such deep drawdowns.

Understanding the 9,525-Day Drawdown Duration

Perhaps the most striking metric in our data is the drawdown duration of 9,525 days. This duration reflects the number of days that have elapsed since the stock last traded at its all-time high of $598.13. This duration translates to more than 26 years of cumulative time spent below the peak, pointing to an all-time high established during a much earlier market era.

A drawdown of this length indicates that the peak price of $598.13 is a highly anomalous historical anchor. For over two decades, the asset has fluctuated, recovered partially, and declined again, without ever reclaiming that ultimate high. This long-term structural drag means that the current -47.0% drawdown is not a short-term correction, but part of a multi-decade market cycle.

When an asset spends 9,525 days in a drawdown, the historical context shifts. The average investor's time horizon is typically much shorter than this duration. Consequently, the vast majority of historical price action has occurred entirely within the boundaries of this single, massive drawdown event.

Comparing Current Metrics to Historical Averages

To understand how unusual the current situation is, we must compare it to the asset's broader historical record. Across the entire history of the stock, we have recorded a total of 19 historical drawdown events. These events represent periods where the stock fell from a local peak and subsequently recovered.

The average max drawdown across all 19 historical events is -12.6%. The current drawdown of -47.0% is nearly four times deeper than this historical average. This massive deviation shows that the current decline is an extreme outlier compared to the typical pullbacks this asset experiences.

Furthermore, the average drawdown duration for all historical events is just 101 days. The current duration of 9,525 days dwarfs this average by orders of magnitude. This comparison underscores the reality that once this stock breaks its typical patterns, the recovery timeline can expand from months to decades.

Analysis of Severe Drops and Historical Recoveries

To find more relevant comparisons, we look specifically at times when the stock dropped by 30% or more. In the history of this asset, we have observed this level of severity only 2 times. This extremely small sample size is an important caveat that investors must keep in mind when analyzing historical averages.

For these severe historical drops of 30% or more, the average duration of comparable drops was 870 days. While 870 days is a substantial period, it is still a fraction of the current 9,525-day drawdown. This suggests that the current event is vastly more persistent than even the worst historical precedents.

The table below contrasts the current drawdown metrics against the asset's historical averages to provide clear structural context.

The contrast between the 101-day average and the 9,525-day current state highlights a stock that has broken out of its typical cyclical behavior. The 2 historical severe drops that averaged 870 days show that recovery from deep territory is historically slow, but the current event has far exceeded those timelines.

Valuation Context and Historical Percentiles

In contrast to the price drawdown, our valuation snapshot as of 2026-06-21 shows that the asset's valuation multiples sit near the top of their own historical ranges. The Price-to-Sales (P/S) ratio stands at 20.2, which is in the 100th percentile of its own daily P/S record since 2006-06-19, compared to a historical median of 1.3. Similarly, the EV-to-EBITDA ratio is 56.2, placing it in the 97th percentile of its own daily record since 2006-07-26, versus a historical median of 6.8. This demonstrates that despite the stock trading 47.0% below its historical peak price, the current valuation multiples are historically elevated relative to the asset's own past record.

Methodology and Data Limits

This drawdown analysis relies strictly on verified historical price, drawdown depth, duration, and severity data. We do not incorporate qualitative assumptions, market narratives, or external fundamental drivers into this evaluation. By focusing entirely on the mathematical reality of the price history, we provide an objective framework for assessing risk.

Our data does not predict future performance, nor does it account for changes in the company's business model, industry conditions, or global macroeconomic factors. The historical patterns of the 19 completed drawdown events provide context, but they do not guarantee how the current 9,525-day event will ultimately resolve.

Investors should view these statistics as a map of past behavior. The extreme variance between the current -47.0% drawdown and the historical -12.6% average shows that past performance is not a rigid template for current cycles.

Technical Thresholds to Watch

To monitor the potential resolution or worsening of this drawdown, we can calculate specific price thresholds. These calculations show what price levels the asset must reclaim to alter its current drawdown status.

To reduce the drawdown from the current -47.0% to a more moderate -30.0%, the stock price would need to rise to $418.69. This would require an increase of approximately 32.1% from the current price of $316.85. Reaching this level would represent a significant shift toward historical recovery norms.

To further reduce the drawdown to -20.0%, the price would need to reach $478.50. This represents a 51.0% increase from current levels. Finally, to completely erase the drawdown and establish a new all-time high, the price must surpass $598.13, which requires a rally of 88.8% from the current price.

These calculated levels provide concrete, data-derived milestones for tracking the stock's progress. Monitoring these levels allows investors to assess whether the asset is beginning to build structural recovery momentum or remaining locked in its long-term red zone status.
