Teledyne's 10% Pullback: What History Says About This 53-Day Slide

Teledyne Technologies Incorporated (TDY) has reached a drawdown of 10.5% as of May 16, 2026, marking a shift from the green zone into the yellow zone. This movement is defined by a Drawdown Severity Score™ of 2.0, which we categorize as Moderately Elevated. The stock has been in this current drawdown period for 53 days, moving away from its all-time high of $688.59.

Understanding the Drawdown Severity Score™

The current Drawdown Severity Score™ of 2.0 indicates that the current price action has exceeded typical volatility for this asset. While Teledyne Technologies Incorporated (TDY) frequently experiences minor pullbacks, a double-digit decline represents a departure from its standard trading range. Our data shows that the average max drawdown for this stock across 170 historical events is only -5.3%.

By reaching a 10.5% drawdown, the stock is now experiencing a decline nearly twice as deep as its historical average. The duration of 53 days is also approaching the historical average drawdown duration of 54 days. When a stock exceeds both its average depth and its average duration, the Drawdown Severity Score™ adjusts to reflect the increased risk profile.

Historical Context and Comparable Events

Our data provides a specific lens through which to view the current 10.5% decline by looking at extreme historical outliers. In the history of Teledyne Technologies Incorporated (TDY), the stock has dropped by 50% or more exactly 3 times. These severe events are rare but provide a necessary ceiling for understanding risk.

The average duration for those comparable drops of 50% or more is 1026 days. It is important to note the small sample size of only 3 events when considering these historical averages. While the current 10.5% drop is far from those historic lows, the transition into the yellow zone suggests that the stock is entering a phase of price discovery that lasts longer than its typical 54-day recovery cycle.

Data-Only Analysis and Limits

This report is a data-only analysis based on the proprietary metrics of DrawdownAlerts. No recent information regarding corporate developments or external market factors is available for Teledyne Technologies Incorporated (TDY) as of May 16, 2026. Consequently, we are not attributing this 10.5% decline to any specific event or market narrative.

Our focus remains exclusively on the price action relative to the all-time high and how the current Drawdown Severity Score™ compares to the 170 historical drawdown events we have tracked for this ticker. We present these figures to provide a statistical baseline for the current sell-off without speculating on the underlying reasons for the price movement.

Technical Thresholds to Monitor

As Teledyne Technologies Incorporated (TDY) sits at a current price of $616.58, investors may look to specific data markers to gauge the next phase of this drawdown. The first marker is the 54-day duration threshold. If the stock remains below its all-time high past May 17, 2026, it will officially be in a longer-than-average drawdown cycle.

The second marker is the Drawdown Severity Score™ itself. A move from the current 2.0 score toward a 3.0 or higher would indicate that the sell-off is accelerating beyond the "Moderately Elevated" yellow zone. Conversely, a reduction in the drawdown percentage below the 10.5% mark would be the first statistical requirement for a return to the green zone.

We will continue to track the exact numbers as they fluctuate. Monitoring whether the stock can reclaim its average recovery timeline or if it continues to drift toward the deeper historical drawdown levels remains the primary focus of our data tracking for this ticker.
