How has Security & Protection Services moved against S&P 500?
The line below covers 5.2 years. Over the most recent two of them this industry is 19% ahead of S&P 500. Earnings across its companies grew 13% on average over the last four reported quarters. It has been ahead of S&P 500 on a rolling three-month view for 5 weeks running.

Participation is spreading downward — the mid and small companies added more this month than the large ones did.
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 12 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.
Sector relative strength · before individual stocks
Is Security & Protection Services outperforming S&P 500?

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.
The GEO Group, Inc. has the strongest current balance of earnings trajectory, business quality, valuation and price confirmation, with 82% evidence confidence.
ADT Inc. looks inexpensive relative to peers or its own history, but its earnings trajectory has not yet earned the valuation signal.
Brady Corporation has stronger price confirmation than earnings confirmation; that is a research prompt, not permission to chase.
Missing observations are not scored as bad. Their missing weight lowers confidence and pulls the final score toward neutral. PEG is guarded: positive earnings, positive 5–60% three-year EPS growth, and a positive P/E are required.
Decision use: Fill the missing evidence before acting; the ranking is deliberately pulled toward neutral.

Revenue Scale & Growth Durability
ADT Inc. has the highest Revenue among the 14 Security & Protection Services companies compared here, at $10,279 million. The Brink's Company is next at $5,390 million. Evolv Technologies Holdings, Inc. has the highest Revenue growth at 42.5%, so level and change sit with different companies. 12 of 14 companies report a comparable reading, the latest through Mar 2026.
What the numbers say: ADT Inc. is the scale leader at $10,279 million, 90.7% ahead of The Brink's Company. Evolv Technologies Holdings, Inc.'s growth is 42.5% from a $161 million base, with 19 reported observations in the 20-quarter window.

This conclusion weakens if: ADT Inc.'s growth falls below Evolv Technologies Holdings, 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.

This conclusion weakens if: CAPEX rises without higher utilization, operating cash flow or incremental returns.
CAPEX is cash spent on property, plant, equipment and other reported capital assets. CAPEX intensity divides that spend by revenue; high intensity is a reinvestment signal, not proof that the reinvestment will earn attractive returns.

This conclusion weakens if: Net debt rises faster than revenue and profit for two consecutive reported periods.
Gross debt shows contractual borrowings. Net debt subtracts reported cash; a negative value means net cash. Lower debt can create capacity, but should be read against the scale and capital intensity of the business.

PEG is shown only when earnings are positive and three-year EPS growth is between 5% and 60%.

What can make this comparison misleading?
This Security & Protection Services comparison names 5 specific ways its own evidence can mislead, all listed below. 1 of the 14 companies reports on an older date than the sector's freshest reporters, so its rank is 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.
1 company has an older fundamental reporting date than the sector’s freshest reporters; its rank carries a stale marker.

All 14 companies in the canonical Security & Protection Services membership are listed below, largest market value first — nothing is silently dropped, even where a company reports too little to rank. The charts above default to a selective view; this register is the complete set, with each company's own latest reporting date beside it.
AHEAD means the company is beating the index by 5% or more over three months. LAGGING, FUNDAMENTALS UP means it is 20% or more behind over a year while its trailing twelve-month earnings grew 20% or more. Both rules are fixed and applied the same way in every sector.
This comparison is built from the reported filings of 14 Security & Protection Services companies, normalized to a common $ scale and a shared quarter axis of up to 20 quarters each. Fundamentals run through Jun 2026 and market data through 2026-07-28. A second data feed fills gaps only after identity and scale reconciliation, and missing observations are never interpolated.

Every one is computed from the same 14 companies and the same reported filings as the rankings and charts, current through Jun 2026. Price and relative-strength answers run through 2026-07-28. Nothing here is estimated, and none of it is a recommendation.
Which Security & Protection Services company is the biggest?
ADT Inc. is the largest, with trailing-twelve-month revenue of $10,279 million, ahead of The Brink's Company at $5,390 million. That covers 12 of 14 companies with comparable reporting through Mar 2026.
Which Security & Protection Services company is growing fastest?
Evolv Technologies Holdings, Inc. has the fastest revenue growth at 42.5% year on year, across 12 of 14 comparable companies. Fast growth off a small base is not the same as proven scale — check whether the rate holds across several quarters on the chart above before treating it as a trend.
Which Security & Protection Services company has the best profit margins?
Bridger Aerospace Group Holdings, Inc. has the highest operating margin at 96.3%, from 13 of 14 comparable companies. Bridger Aerospace Group Holdings, Inc. shows the biggest recent improvement, at +51.4 percentage points. A high margin matters most when it is holding or rising, not when it is peaking.
Which Security & Protection Services company makes the most profit?
ADT Inc. earns the most, at $627 million of trailing-twelve-month net profit, from 12 of 14 comparable companies. The GEO Group, Inc. has the fastest profit growth at 100%, though growth off a small or recovering profit base overstates how much has actually changed.
Which Security & Protection Services company earns the highest return on capital?
Allegion plc leads on return on capital employed at 5.8%, across 14 of 14 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 Security & Protection Services stock is the cheapest?
On guarded PEG — where a LOWER number is cheaper — The GEO Group, Inc. screens cheapest at 0.4×. Only 9 of 14 companies pass the comparability guard, 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.
Which Security & Protection Services company has the strongest balance sheet?
CompX International Inc. carries the lowest comparable gross debt at $1 million, from 13 of 14 companies. Absolute rupee debt alone does not settle it, because company scale differs — net debt and debt-to-equity in the chart above carry more information, and a very low-debt balance sheet can also mean under-investment.
Which Security & Protection Services company is investing most in new capacity?
ADT Inc. reports the largest capital spending at $140 million, across 14 of 14 companies. Spending consumes cash before it earns anything, so treat the ranking as a diligence queue: check commissioning, utilisation and the return earned on the completed assets before reading spend as value creation.

Which Security & Protection Services stock has the strongest price momentum?
The GEO Group, Inc. has the strongest relative strength against S&P 500. Relative strength answers last, after growth, quality and valuation: price can move well before the fundamentals confirm it, and sometimes without them confirming at all.
Which Security & Protection Services company scores highest for research priority?
The GEO Group, Inc. scores 73.1 out of 100 with 82% evidence confidence, from 25.9 points on growth and earnings, 11 on capital efficiency, 16.2 on valuation and 20 on relative strength. This ranks what deserves work next. It is not a buy recommendation, and management quality, catalysts and risk still need separate research.
