TransDigm Group Is Down 21% in 234 Days. What History Says.

As of May 20, 2026, TransDigm Group Incorporated (TDG) has moved out of the red zone and into the yellow zone as its Drawdown Severity Score™ improved to 4.7. The stock remains in a drawdown of 21.0% from its all-time high, having spent 234 days in this current decline.

Transition from Red to Yellow Severity

The shift from the red zone to the yellow zone indicates a stabilization in the Drawdown Severity Score™ for TransDigm Group Incorporated (TDG). This move suggests that while the stock remains in a significant drawdown, the intensity of the price contraction has moderated compared to previous weeks. As of May 20, 2026, the Drawdown Severity Score™ of 4.7 places the asset in a category where risk remains elevated but is no longer at peak historical intensity for this specific ticker.

Our data shows the stock is trading at $1198.09, which is a 21.0% decline from the all-time high of $1516.55. This 234-day duration is substantially longer than the average drawdown for this asset. Historically, across 241 total drawdown events, the average drawdown duration for this stock is only 27 days. The current cycle has exceeded that average by more than 200 days, marking this as a persistent period of price depression.

Historical Context of 20% Pullbacks

When evaluating the current 21.0% drawdown, we must look at how TransDigm Group Incorporated (TDG) behaves during major corrections. The average maximum drawdown across the stock's entire history is just -3.8%. The current level of -21.0% represents a significant deviation from the standard price behavior of this asset.

Our data indicates that the stock has dropped by 25% or more only 3 times in its history. While the current 21.0% drawdown has not yet reached that 25% threshold, it is approaching a level that has historically triggered long-term recovery cycles. For the 3 times the stock reached a 25% decline, the average duration of those comparable drops was 536 days.

We must note that this is a small sample size of only 3 events. This limited historical data means that while the average duration of 536 days provides a benchmark, it may not predict the specific timeline for the current 234-day event.

Severity Thresholds and Data Limits

The transition to a Drawdown Severity Score™ of 4.7 is a quantitative observation based on price action and volatility relative to the stock's lifetime performance. This analysis relies exclusively on price, drawdown depth, duration, and historical frequency. We do not incorporate external market factors, corporate developments, or macroeconomic indicators into this score.

The "yellow zone" status as of May 20, 2026, reflects that the stock is no longer at its most extreme drawdown velocity, yet it remains far from a full recovery. In previous cycles, a move from red to yellow has often preceded a period of consolidation. However, the current duration of 234 days highlights that this specific event is more protracted than the majority of the 241 historical drawdowns we have tracked for this ticker.

Monitoring the Recovery Path

For investors monitoring TransDigm Group Incorporated (TDG), the path back to the all-time high of $1516.55 requires a significant reversal in price action. A move back into the red zone would occur if the Drawdown Severity Score™ increases, which typically happens if the drawdown deepens toward the 25% threshold or if price volatility accelerates at these lower levels.

Conversely, a move into the green zone would require a continued reduction in the drawdown percentage and a stabilization of price. Given that the average drawdown for this stock is only -3.8%, the current 21.0% level remains an outlier in the stock's historical profile. We will continue to monitor the Drawdown Severity Score™ to determine if this move to the yellow zone is a temporary pause or a shift toward a recovery trend.
