FormFactor Is Down 30%. What History Suggests.

FormFactor Is Down 30% in 58 Days. What History Suggests.

FormFactor, Inc. (FORM) is now down 30% from its all-time high as of September 17, 2026, having just exited the red zone after 58 days in drawdown. Our proprietary Drawdown Severity Score™ has improved to 4.5, placing the stock in the yellow zone. In 4 comparable prior drops of this depth, the stock took an average of 1828 days to recover, though this represents a very small sample size of historical occurrences.

Exiting the Red Zone: FormFactor's Severity Improvement

Our data shows that FormFactor, Inc. (FORM) has experienced a shift in its drawdown risk profile as of September 17, 2026. The stock closed at $111.53, which is exactly 30.3% below its all-time high of $159.93. This price action marks an exit from the high-risk red zone and a transition into the yellow zone, which represents a "Significant" severity level.

The shift is reflected in the Drawdown Severity Score™, which has adjusted to 4.5. This improvement suggests that while the stock remains in a deep drawdown, the downward momentum has stabilized enough to trigger a zone upgrade. We monitor these zone transitions closely because they often signal a change in the underlying price regime.

The Anatomy of the Current Drawdown

The current drawdown began 58 days prior to September 17, 2026, when the stock peaked at its all-time high of $159.93. Since reaching that peak, the stock has experienced a steady decline to its current price of $111.53. This represents a total peak-to-trough drop of $48.40 per share.

A drawdown of 30.3% over a 58-day period is a rapid contraction compared to typical market movements. The speed and depth of this decline initially pushed the stock into the red zone, indicating extreme near-term weakness. The transition to the yellow zone indicates that the rate of decline has moderated, even though the total drawdown remains substantial.

The Mathematics of Drawdown Recovery

Understanding the mechanics of drawdowns requires looking at the mathematical asymmetry of recoveries. To recover from a 30.3% decline, an asset must achieve a 43.5% gain from its trough price just to return to its previous peak. This compounding effect explains why deep drawdowns require significantly more upward effort to resolve than mild pullbacks.

When a stock enters a 30.3% drawdown, the path back to even is mathematically steeper than the path down. For example, a minor 10% drop only requires an 11.1% gain to recover. Once a drawdown crosses the 30% threshold, the required recovery performance escalates rapidly, which is why these events often persist for extended periods.

Historical Comparison: How Prior 30% Drops Played Out

To understand what this zone exit means, we must analyze the historical record of FormFactor, Inc. (FORM). Our database has tracked a total of 48 historical drawdown events for this asset. Across all 48 of these events, the average maximum drawdown was only -13.4%, and the average drawdown duration was 174 days.

The current drawdown of -30.3% is more than double the historical average depth. This indicates that the current sell-off is an outlier when compared to the typical pullbacks the stock has experienced over its trading history.

When we look specifically at severe drawdowns where the stock dropped by 30% or more, we find that this has occurred only 4 times in the company's history. The average duration of these comparable drops is 1828 days. This is a crucial metric because it shows that deep drawdowns for this stock have historically taken years, not months, to fully resolve.

However, we must emphasize a critical caveat: the sample size for these 30%+ drawdowns is extremely small. With only 4 comparable historical events, the statistical average of 1828 days may not reliably predict future recovery timelines. Investors should treat this average as historical context rather than a definitive forecast.

The table highlights the stark contrast between a typical pullback and a major correction for this stock. While a normal drawdown resolves in less than six months, a drop exceeding 30% has historically entered a multi-year recovery cycle.

Historical Drawdown Distribution for FORM

Analyzing the distribution of the 48 historical drawdown events provides deeper insight into how unusual the current drop is. The vast majority of these 48 events were minor pullbacks that never exceeded a 15% decline. These frequent, shallow dips are characteristic of normal trading behavior for this asset.

In contrast, the 4 events that crossed the 30% threshold represent the extreme tail end of the stock's historical volatility distribution. This means that approximately 8.3% of all drawdowns for this stock reach the severity of the current decline. The rarity of these events suggests that a 30.3% drop represents a significant shift in the asset's historical price pattern.

Valuation Context vs. Historical Drawdowns

For historical context, we can contrast the current price drawdown with the asset's valuation multiples as of 2026-09-13. The Price-to-Sales (P/S) ratio stands at 8.8, placing it in the 97th percentile of its own daily P/S record since 2006-09-11, compared to its historical median of 2.6. Meanwhile, the EV-to-EBITDA (EV/EBITDA) ratio is 40.6, which is in the 83rd percentile of its own daily EV/EBITDA record since 2006-09-11, versus a historical median of 20.6. These figures show that despite the -30.3% price decline, the stock's valuation multiples remain high within its own historical range.

Data Limits and Analysis Methodology

Our analysis relies strictly on historical price, drawdown, and valuation data. We do not incorporate external qualitative factors, macroeconomic indicators, industry trends, or company-specific news. This approach ensures that our findings remain completely objective and data-driven.

Because we limit our scope to quantitative metrics, we do not make causal claims about why the stock fell or why it transitioned between severity zones. The historical patterns we identify show what has happened in the past under similar technical conditions, but they cannot account for unique future developments.

Key Levels and Severity Thresholds to Watch

As FormFactor, Inc. (FORM) navigates the yellow zone, several key technical thresholds will determine its next severity classification. Understanding these levels helps track whether the stock is stabilizing or preparing for another leg down.

To maintain its current yellow zone status or improve further, the stock must avoid breaking below its recent low points. A deeper slide that pushes the drawdown past the -35% mark would likely trigger a return to the red zone, indicating a renewal of high-severity risk.

Conversely, a sustained move upward would reduce the drawdown percentage. If the drawdown shrinks toward the -20% level, the Drawdown Severity Score™ would adjust downward, potentially moving the stock into the green or blue zones, which represent lower risk categories. We will continue to track these metrics as new price data becomes available.
