Diagnostics & Research Stocks
Diagnostics & Research: Thermo Fisher Scientific Inc. owns the largest revenue base; BillionToOne, Inc. has the fastest current growth.
01 · the industry itself · before any single company
How has Diagnostics & Research moved against S&P 500?
The line below covers up to 5.2 years and opens on the 5Y view; the buttons cut it shorter. Over the most recent two of them this industry is 52% ahead of S&P 500. Earnings across its companies grew 8% on average over the last four reported quarters — close to flat. It has been ahead of S&P 500 on a rolling three-month view for 16 weeks running.

Both lines start at 200 in the same week, so the distance between them is the whole story: the industry line is an equal-weighted index of its 33 companies. The bars underneath are trailing 12-month earnings per share, one bar per reported quarter, each member rebased to 100 at the start and the industry taking the median — so a price line pulling away from flat bars is a re-rating, not earnings. A bar turns red when that figure is lower than the quarter before. Rules are fixed and applied identically everywhere on this site: ahead by 5% or more over three months, or behind by 20% or more over a year while earnings grew 20% or more. Hover any point to read both values and the gap. This is a description of what the numbers did, not advice.
02 · sector relative strength, before individual stocks
Is Diagnostics & Research outperforming S&P 500?
Diagnostics & Research has outperformed S&P 500 by 44.3% over the last 52 weeks. Over 13 weeks the gap is a lead of 33.8%. 22 of 29 covered companies currently beat the S&P 500 on Mansfield relative strength, so leadership inside the sector is selective. Twist Bioscience Corporation is the strongest against the sector itself at +79.4%.

The central tension: the companies with the most scale are not necessarily the companies creating the most change.
Start with scale. Then earnings trajectory. Then business quality. Only after those three agree should price leadership carry much weight.
Bottom line
Diagnostics & Research has outperformed S&P 500 by 44.3% over 52 weeks and 33.8% over 13 weeks. 22 of 29 covered companies beat the S&P 500 on Mansfield relative strength, while 10 of 29 beat the sector itself. Thermo Fisher Scientific Inc. leads with revenue of $46,336 million, based on 19 of 30 comparable companies through Jun 2026.

4-Factor Sector Score
An additive sector-relative research score. The four displayed point contributions always equal the total: Growth & earnings (35), Capital efficiency (25), Valuation (20), and Relative strength (20). Missing or stale evidence is absorbed inside the affected factor, never applied as a hidden adjustment.
Growth & earnings · 35%Capital efficiency · 25%Valuation · 20%Relative strength · 20%
Labcorp Holdings Inc. has the strongest current balance of earnings trajectory, business quality, valuation and price confirmation, with 81.1% evidence confidence.
Charles River Laboratories International, Inc. has stronger price confirmation than earnings confirmation; that is a research prompt, not permission to chase.
How this score is built, and what the marks mean
Missing observations are not scored as bad. Their missing weight lowers confidence and pulls the final score toward neutral. PEG is not shown when the ratio cannot mean anything: the company must be making a profit, its price-to-earnings must be positive, and its three-year earnings growth must fall between 5% and 60%. Dividing a price multiple by a loss, or by growth measured off a tiny base, produces a number that looks precise and tells you nothing. Under relative strength, one mark per week shows the last 12 weeks: a mark is filled where the company led S&P 500 by 5% or more over the 13 weeks ending that week, which is the same test used everywhere on this site. Price stage places the company on the same six-step curve the sector itself is placed on — basing, turning, breaking out, leader, fading, asleep — read from how many weeks running it has led S&P 500 and whether that lead is widening or shrinking. It describes where the PRICE stands, not the earnings trajectory and not a recommendation, and it is left blank for a company whose weekly history is too short or too stale to read.

Market action
Twist Bioscience Corporation has the strongest one-year price move in Diagnostics & Research at +413%. It also leads on Mansfield relative strength against the S&P 500 at +121.5%. 22 of 29 covered companies are above zero on that measure. Every line covers 314 weekly closes through 2026-09-16.
Price and relative strength
Every company, the sector's own index and S&P 500 all start level on the left edge of the window, so only the distance between the lines counts — the highest line has risen the most since then, and the chart at the top of this page is drawn the same way. It opens on one year; the buttons beside it stretch that to three or five.
How far ahead of or behind S&P 500 each company has been running, measured against its own recent average of that comparison, so the flat line at zero IS S&P 500: above it the company is beating the market, below it the market is beating the company. It opens on one year.
The same measure taken against Diagnostics & Research itself instead of the whole market, so the flat line at zero is the sector: above it the company is beating its own peers, which is the sharper test of the two. It opens on one year.

Revenue Scale & Growth Durability
Thermo Fisher Scientific Inc. has the highest Revenue among the 30 Diagnostics & Research companies compared here, at $46,336 million. Danaher Corporation is next at $25,107 million. BillionToOne, Inc. has the highest Revenue growth at 99.4%, so level and change sit with different companies. 19 of 30 companies report a comparable reading, the latest through Jun 2026.
What the numbers say: Thermo Fisher Scientific Inc. is the scale leader at $46,336 million, 84.6% ahead of Danaher Corporation. BillionToOne, Inc.'s growth is 99.4% from a $355 million base, with 9 reported observations in the 20-quarter window. Treat the growth leader as an acceleration candidate, not as equally proven scale.
LeaderThermo Fisher Scientific Inc. · $46,336 million
Gap84.6% versus #2 · Danaher Corporation
Persistence7/8 recent comparable periods
Coverage19/30 companies · 530 observations
Investor read: Thermo Fisher Scientific Inc. is the scale benchmark; BillionToOne, Inc. is the acceleration watch. Promote the challenger only if growth persists and converts into margin and returns.
This conclusion weakens if: Thermo Fisher Scientific Inc.'s growth falls below BillionToOne, Inc.'s for two consecutive comparable reports while operating margin also compresses.
Revenue is compared on a common reported-currency basis. Growth is year-on-year, so seasonality does not masquerade as progress.

Coverage30/30 companies · 527 observations
Investor read: IDEXX Laboratories, Inc. sets the level benchmark; use the change leader as an inflection watch only after another comparable report confirms it.
This conclusion weakens if: The next two comparable reports reverse the current margin change signal.
Operating margin compares operating profit with revenue. Improvement is measured in percentage points, not percentage growth.

Investor read: Thermo Fisher Scientific Inc. sets the level benchmark; use the change leader as an inflection watch only after another comparable report confirms it.
This conclusion weakens if: The next two comparable reports reverse the current profit growth signal.
Net profit is the residual after operating costs, interest and tax. Growth off a loss or near-zero base is excluded from the fastest-grower rank.

Valuation Against Growth & Quality
Labcorp Holdings Inc. has the lowest PEG among the 30 Diagnostics & Research companies compared here, at 0.69×. Agilent Technologies, Inc. is next at 1.01×. CareDx, Inc. has the lowest P/E at 13.8×, so level and change sit with different companies. 8 of 30 companies report a comparable reading, the latest through Jun 2026.
What the numbers say: Labcorp Holdings Inc. has the lowest comparable PEG at 0.69×, 31.7% below Agilent Technologies, Inc.. Only 8 of 30 companies have earnings and growth steady enough for the ratio to mean anything, so no broad “cheapest stock” conclusion is defensible unless the current multiple, own-history position and growth durability agree.

Persistence0/8 recent comparable periods
Coverage8/30 companies · 74 observations
Investor read: Treat valuation as permission to investigate, never as a standalone reason to buy.
This conclusion weakens if: The next two comparable reports reverse the current p/e signal.
PEG is shown only when earnings are positive and three-year EPS growth is between 5% and 60%. It is recomputed consistently as the trailing P/E divided by that growth rate — reported earnings, never an expected-earnings multiple. On Indian companies it is shown only where the two data feeds agreed. Where any of that fails the ratio is left out rather than printed: a P/E divided by a loss, or by growth measured off a tiny base, is a number that looks precise and means nothing.

What can make this comparison misleading?
This Diagnostics & Research comparison names 5 specific ways its own evidence can mislead, all listed below. 9 of the 30 companies report on an older date than the sector's freshest reporters, so their ranks are marked stale. A high growth rate can still be a low-base artefact.
Keep these limits visible
- A high growth rate can be a low-base artefact. The page keeps level and change separate for that reason.
- A high ROCE can be temporary or flattered by a small capital base. Read it beside margin, cash conversion and reinvestment.
- The 4-Factor Sector Score ranks research priority, not portfolio action. Management quality, catalysts and risks need equally fresh evidence before capital is deployed.
- An “all companies” line chart preserves completeness, but rank changes should be checked against reporting dates before drawing a conclusion.
- 9 companies have older fundamental reporting dates than the sector’s freshest reporters; their ranks carry a stale marker.

How was this comparison built?
This comparison is built from the reported filings of 30 Diagnostics & Research companies, normalized to a common $ scale and a shared quarter axis of up to 20 quarters each. Fundamentals run through Sep 2026 and market data through 2026-09-16. A second data feed fills gaps only after identity and scale reconciliation, and missing observations are never interpolated.

Diagnostics & Research company comparison FAQs
These 22 answers restate the Diagnostics & Research comparison above in question form. Every one is computed from the same 30 companies and the same reported filings as the rankings and charts, current through Sep 2026. Price and relative-strength answers run through 2026-09-16. Nothing here is estimated, and none of it is a recommendation.
Is the Diagnostics & Research sector outperforming S&P 500?
Diagnostics & Research has outperformed S&P 500 by 44.3% over 52 weeks and 33.8% over 13 weeks. 22 of 29 covered companies beat the S&P 500 on Mansfield relative strength, while 10 of 29 beat the sector itself.
Which Diagnostics & Research company is largest by revenue?
Thermo Fisher Scientific Inc. leads with revenue of $46,336 million, based on 19 of 30 comparable companies through Jun 2026.
Which Diagnostics & Research company is growing fastest?
BillionToOne, Inc. has the fastest current revenue growth at 99.4%, across 19 of 30 comparable companies.
Which Diagnostics & Research company has the strongest 4-Factor Sector Score?
Labcorp Holdings Inc. ranks first at 62.1/100 with 81.1% evidence confidence. The score prioritizes research; it is not a buy recommendation.
Which Diagnostics & Research company has the lowest comparable PEG?
Labcorp Holdings Inc. has the lowest comparable PEG at 0.69, among 8 of 30 companies whose earnings and growth are steady enough for the ratio to mean anything.
How much history does this Diagnostics & Research comparison include?
The page compares up to 20 reported quarters per company for fundamentals, returns and valuation, ending Sep 2026. Missing observations remain blank rather than being estimated.
How is the 4-Factor Sector Score calculated?
The four visible contributions add directly: growth and earnings up to 35 points, capital efficiency up to 25, valuation up to 20, and relative strength up to 20. Missing or stale evidence moves only the affected contribution toward neutral.
Which Diagnostics & Research company is the biggest?
Thermo Fisher Scientific Inc. is the largest, with trailing-twelve-month revenue of $46,336 million, ahead of Danaher Corporation at $25,107 million. That covers 19 of 30 companies with comparable reporting through Jun 2026.
Which Diagnostics & Research company has the best profit margins?
IDEXX Laboratories, Inc. has the highest operating margin at 35%, from 30 of 30 comparable companies. GRAIL, Inc. shows the biggest improvement (+149.6 percentage points — see the chart above for the starting level). A high margin matters most when it is holding or rising, not when it is peaking.
Which Diagnostics & Research company makes the most profit?
Thermo Fisher Scientific Inc. earns the most, at $6,988 million of trailing-twelve-month net profit, from 19 of 30 comparable companies. Qiagen N.V. has the fastest profit growth at the ≥100% scoring cap, though growth off a small or recovering profit base overstates how much has actually changed.
Which Diagnostics & Research company earns the highest return on capital?
Medpace Holdings, Inc. leads on return on capital employed at 30.2%, across 30 of 30 companies. Read it beside the length of its reported history: a high return that repeats for years is evidence of a durable business, while a single high reading can be a small capital base or one good year.
Which Diagnostics & Research stock is the cheapest?
On PEG — where a LOWER number is cheaper — Labcorp Holdings Inc. screens cheapest at 0.69×. Only 8 of 30 companies have earnings and growth steady enough for the ratio to mean anything, so this is not a sector-wide "cheapest stock" verdict. Cheap on a multiple is a reason to investigate, never a reason to buy on its own.

Is this investment advice?
