Current Drawdown Severity and Zone Transition

The transition from the red zone to the yellow zone indicates a stabilization in the Drawdown Severity Score™ for Talen Energy Corporation (TLN). Our data shows the current severity score is 5.0, which we classify as Significant. This score is anchored by the fact that the stock remains 22.7% below its all-time high of $445.84.

The 164-day duration of this sell-off is substantially longer than the historical norms for this asset. Our records indicate that across 61 total historical drawdown events, the average drawdown duration for this stock is only 11 days. The current cycle has now persisted for nearly 15 times the historical average duration.

Contextualizing the 23% Decline

When looking at the depth of the price contraction, the current 22.7% drawdown stands in stark contrast to the historical average max drawdown of -4.1%. As of May 20, 2026, the stock is experiencing a volatility event that far exceeds the typical retracements seen in its trading history.

The move out of the red zone suggests that while the drawdown remains deep, the velocity or depth of the decline has moderated enough to shift the Drawdown Severity Score™. This yellow zone status reflects a state of elevated risk that is no longer at the extreme levels characterized by the red zone.

Historical Comparison of Major Drawdowns

To understand the current positioning of Talen Energy Corporation (TLN), we examined how many times the stock has dropped by 15% or more from a peak. Our data shows this has happened 4 times in the asset's history.

In these comparable instances where the drawdown exceeded 15%, the average duration of the drop was 48 days. The current 164-day duration as of May 20, 2026, indicates this is an outlier event in terms of time. It is important to note the small sample size for these 15% or greater declines: with only 4 events on record, historical averages may be less predictive than in stocks with more frequent deep pullbacks.

Data-Driven Analysis Limits

Our analysis of Talen Energy Corporation (TLN) relies exclusively on verified price, drawdown, and severity data as of May 20, 2026. We do not incorporate external market narratives, earnings reports, or macroeconomic factors into this assessment. The Drawdown Severity Score™ is a proprietary metric calculated based on the stock's own price history and drawdown behavior. This focus allows for a pure technical assessment of risk levels relative to historical performance without the influence of subjective market sentiment.

Severity Thresholds to Monitor

Investors monitoring the risk profile of Talen Energy Corporation (TLN) should look to specific data points that would trigger a change in the Drawdown Severity Score™. A move back into the red zone would typically be preceded by a widening of the drawdown beyond the current 22.7% or an acceleration in downward price velocity.

Conversely, a move toward the green zone would require a significant reduction in the distance from the all-time high of $445.84. Given the current price of $344.46, the stock requires a substantial percentage gain to close the remaining gap. We will continue to track the Drawdown Severity Score™ as it reacts to new price data.
