Labcorp Is Down 12% in 180 Days. What History Says.

As of June 18, 2026, Labcorp Holdings Inc. (LH) has crossed into the yellow zone as its drawdown reached -11.8%, marking a 179-day decline from its all-time high of $290.15. This shift triggers a Drawdown Severity Score™ of 2.3, which indicates a moderately elevated risk level for the stock. This transition from the green zone highlights a prolonged period of selling pressure that exceeds the stock's typical historical pullback depth.

The Significance of Labcorp's Yellow Zone Transition

Our data shows that Labcorp transitioned from the green zone to the yellow zone as of June 18, 2026. This movement reflects a Drawdown Severity Score™ of 2.3, which signals that the stock has moved past routine market noise into a moderately elevated drawdown phase.

Historically, the asset spends the majority of its time in the green zone, where pullbacks remain minor and short-lived. Crossing the threshold into the yellow zone indicates that the current -11.8% decline has surpassed the historical baseline for typical fluctuations.

With the price sitting at $255.82 as of June 18, 2026, LH is experiencing a drawdown that is more than double its historical average. Investors tracking the asset must now evaluate how prior transitions of this magnitude have behaved over extended periods.

The Drawdown Severity Score™ is designed to normalize risk by comparing the current decline's depth and duration against the asset's entire historical record. When the score rises to 2.3, it indicates that the current selling pressure is starting to mirror historical periods of prolonged corrections rather than temporary dips.

Current Drawdown Metrics and Historical Benchmarks

To understand the depth of the current decline, we must compare the June 18, 2026 data against the long-term historical performance of LH. Across 136 total historical drawdown events recorded in our database, the average maximum drawdown for this stock is -5.5%. The current decline of -11.8% represents a significant departure from this average.

The duration of the current decline also stands out. While the historical average drawdown duration for LH is 94 days, the current drawdown has lasted 179 days as of June 18, 2026. This extended timeframe indicates a persistent downward trend rather than a rapid, sharp correction.

To put these numbers into perspective, we can look at the recovery hurdle required to return to previous peaks. From the price of $255.82 as of June 18, 2026, LH must gain approximately 13.4% to reach its all-time high of $290.15. By contrast, a typical historical drawdown of -5.5% requires a recovery gain of only 5.8% to break even.

This table highlights how the current drawdown has extended both in depth and duration relative to typical historical pullbacks. The historical averages include all 136 recorded drawdown events, many of which resolved quickly within the green zone.

How LH Behaves After Crossing the 10% Threshold

A drop of 10% or more is a relatively infrequent event for LH. Our data shows that since the inception of our tracking, LH has dropped by 10% or more exactly 19 times. When the stock crosses this threshold, the historical recovery timeline lengthens considerably.

The average duration of these comparable 19 drops is 587 days. This average duration includes the total time spent falling from the peak to the trough, as well as the time required to recover back to the previous all-time high of $290.15.

The difference between a minor pullback and a major drawdown becomes clear when analyzing these larger events. The following table contrasts the general historical averages against the subset of drawdowns that exceeded the 10% threshold.

The data indicates that once LH enters a drawdown of this depth, the resolution process has historically required a multi-month commitment. The 179-day duration as of June 18, 2026, when compared to the 587-day average for comparable drops, shows that the asset has historically spent a considerable amount of additional time in recovery during similar cycles.

In historical terms, a 587-day average duration means that a full recovery cycle can span more than a year and a half. Since LH has spent 179 days in this drawdown as of June 18, 2026, it has traversed only a fraction of the average timeline associated with past double-digit declines.

The Anatomy of LH's Historical Drawdown Distribution

Analyzing the distribution of LH's 136 historical drawdown events provides critical context for understanding the rarity of the current market state. Of the 136 total drawdowns, only 19 have reached or exceeded a depth of -10%. This means that approximately 14% of all historical pullbacks have developed into double-digit declines.

The remaining 86% of historical drawdowns resolved before reaching the -10% threshold, typically finding a bottom and recovering within the average 94-day window. This skewed distribution demonstrates that LH historically exhibits strong price stability, with the vast majority of pullbacks remaining shallow and brief.

By crossing the -10% mark and reaching -11.8% as of June 18, 2026, the current drawdown has officially entered the tail end of the historical distribution. This placement explains why the Drawdown Severity Score™ has moved to 2.3, signaling that the price behavior is statistically distinct from the stock's standard historical performance.

This distribution highlights why the transition to the yellow zone is a notable event for LH. The stock has moved out of its high-probability recovery zone (under 10% depth) and into a historical regime where recoveries have historically taken much longer to materialize.

Valuation Context Within LH's Historical Range

As of 2026-06-17, the Price-to-Sales ratio (P/S) for LH stands at 1.6, which ranks in the 79th percentile of its own daily history since 2006-06-16, sitting above its historical median of 1.4. Similarly, the EV-to-EBITDA ratio (EV/EBITDA) is 13.7, placing it in the 85th percentile of its daily historical record since 2006-06-16, which is also above its historical median of 9.6. This contrasts with the -11.8% price drawdown, showing that despite the decline in share price, the company's valuation multiples remain high relative to its own historical range.

Methodology and Data Parameters

This analysis relies exclusively on verified price, drawdown, severity, and historical valuation data. We do not incorporate external market narratives, macroeconomic factors, or corporate announcements into this evaluation. By focusing solely on quantitative price history and drawdown behavior, we aim to provide an objective framework for assessing risk.

Our calculations use the daily price history of LH to map out drawdown cycles from peak to trough. This systematic approach allows us to compare the current 179-day decline against the 136 historical drawdown events without subjective bias.

The Drawdown Severity Score™ is a proprietary metric that evaluates the depth and duration of an active drawdown against all historical occurrences of the same asset. This methodology ensures that the risk rating is tailored specifically to LH's unique historical volatility profile, rather than applying a generic market-wide standard.

Technical Thresholds and Risk Markers to Watch

As LH continues its trajectory within the yellow zone, several key metrics will dictate whether the risk profile intensifies or begins to stabilize. The primary indicator to monitor is the Drawdown Severity Score™, which sits at 2.3 as of June 18, 2026. A further slide in price that pushes the drawdown past the June 18, 2026 level of -11.8% could cause the severity score to rise, potentially moving the stock closer to the orange zone.

Conversely, a sustained upward price movement would begin the recovery phase, though history suggests this process can be lengthy. If the drawdown duration of 179 days begins to approach the historical 587-day average for 10% drops, it would align with the longer-term recovery patterns observed in prior cycles. Monitoring these specific boundaries provides a data-driven method for tracking LH's risk environment.

Specifically, investors can monitor the $290.15 level, which represents the previous peak. Reclaiming this level would officially mark the end of the current drawdown cycle, while failing to make progress over the coming months would continue to push the duration closer to historical averages for severe declines.
