TMO Recovers: How This Drawdown Compares to Its Past

As of June 26, 2026, Thermo Fisher Scientific Inc. (TMO) moved from the red zone to the yellow zone. The verified drawdown is 22.3% from its all-time high, with the stock at $513.03 versus a high-water mark of $660.35. Its Drawdown Severity Score™ is 4.6, which places it in the Significant range.

What changed in the data

This article uses only DrawdownAlerts price, drawdown, duration, severity, and historical-drawdown records. The zone transition matters after the severity score crossed a defined threshold in the DrawdownAlerts framework. A move into a yellow zone means the current drawdown profile now sits in a less severe part of the ticker's own historical range.

The current drawdown has lasted 1,564 days. That duration is important alongside the drawdown depth. A short, deep decline and a long, grinding decline can both reach the same zone, but they tell different risk-context stories. Here, the current reading combines a 22.3% drawdown with 1,564 days below the high-water mark.

Current drawdown context

The all-time high used in this analysis is $660.35. The latest verified price is $513.03. Those two numbers anchor the current drawdown calculation and keep the article focused on measurable data rather than outside narrative.

The average maximum drawdown in the stored TMO history is 4.6%, and the average drawdown duration is 48 days. The current drawdown is therefore compared against the ticker's own record, not against a broad market average. That is the point of the Drawdown Severity Score™: it normalizes the current decline against what this ticker has actually done before.

Historical comparison

DrawdownAlerts has 8 comparable historical TMO drawdown records at or beyond the 20% threshold. The average duration in that comparison set is 855 days. The comparison set is shown as historical context, not as a forecast.

There are 265 total drawdown records in the stored TMO history used by this system. The comparable set above is narrower. It looks only at drawdowns that reached the selected threshold, which makes it more relevant to the current setup than a simple average across every past pullback.

The threshold is intentionally tied to the depth of this event. A comparison that is too shallow can make a normal pullback look more dramatic than it is, while a threshold that is too deep can leave too little history to evaluate. DrawdownAlerts uses the nearest available comparison level with enough historical records when possible, then shows the count so readers can judge the sample size.

This is why the article separates the event reading from the full drawdown history. The event reading says what changed as of June 26, 2026. The historical table shows how often similar drawdowns have appeared in the stored record. Those are related, but they are not the same claim.

For readers using this as a monitoring signal, the useful question is not whether history will repeat. It is whether the current score, depth, and duration keep moving into a more unusual range or start moving back toward ordinary territory for this ticker.

Valuation context

Valuation context, as of 2026-06-26: for Thermo Fisher Scientific Inc., its P/S ratio of 4.2 sits in the 63rd percentile of its own daily record since 2006-06-26, within its own typical range (historical median 3.5), and its EV/EBITDA ratio of 20.5 sits in the 73rd percentile of its own daily record since 2006-06-26, above its own typical range (historical median 18.3). These percentiles compare this asset only with its own past record. A low percentile means the multiple is low relative to its own history; it is historical context, not a forecast or a recommendation.

Data boundary

This is a data-only transition brief. It does not assign an outside explanation for the move. The article is intentionally limited to price history, drawdown depth, time in drawdown, severity score, and comparable DrawdownAlerts records.

That boundary is important. A zone change is a measurement event. It says the ticker crossed a severity threshold. It does not, by itself, explain why the price moved. The practical value is that it gives investors a consistent way to notice when a ticker's current drawdown has become more or less unusual versus its own past.

Because this article is anchored to June 26, 2026, later market moves can make the live ticker page look different from the article snapshot. That is expected. The article records why the transition was notable when it happened, while the ticker page remains the place to inspect the latest price, score, and zone.

What to monitor next

The next useful readings are the Drawdown Severity Score™, the current drawdown percentage, and the number of days the ticker remains below its all-time high. If the score moves farther into the yellow zone, the current drawdown is becoming more unusual in DrawdownAlerts data. If the score moves back toward the prior zone, the measured stress is easing relative to the ticker's own historical range.

For TMO, the present transition is already enough to merit a fresh article after it crossed a green, yellow, or red boundary. That is the coverage rule for DrawdownAlerts market-event content: true zone transitions receive coverage, while same-zone velocity moves remain optional.
