The line below covers up to 5.2 years and opens on the 5Y view; the buttons cut it shorter. Over the last two years (104 weeks) this industry is 0% ahead of S&P 500. Earnings across its companies grew 3% on average over the last four reported quarters, close to flat.

13 of 31 companies ahead of S&P 500 by 5% or more over three months. 3 are 20% or more behind over a year while earnings grew 20% or more.

Ahead of S&P 500 on the three-month view for 3 weeks running; 16 of the 31 companies in the industry index above their 200-day average (1 more than four weeks earlier); 13 of those 31 ahead of S&P 500 by 5% or more over three months (2 more than four weeks earlier); earnings rising at 18 of the 30 that report earnings.

Ahead of S&P 500 for 3 weeks after being behind, with 11 → 13 of 31 participating. Earnings mixed, 18 of 30 members have higher trailing twelve-month earnings than a year ago.

Both lines start at 200 in the same week, so the gap between them tells the story: the industry line is an equal-weighted index of its 31 companies. The bars underneath are trailing 12-month earnings per share, one bar per reported quarter, each member set to 100 at the start and the industry taking the middle value, so a price line pulling away from flat bars means the market is paying more for the same earnings. A bar turns grey when that figure is lower than the quarter before. The rules are fixed and the same 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 or tap any point to read both values and the gap.

Specialty Business Services has done better than the S&P 500 by 15.4% over the last 52 weeks. Over 13 weeks the gap is a lead of 3.2%. BUUU Group Limited is the strongest against the sector itself at +164.8%.

Specialty Business Services has done better than the S&P 500 by 15.4% over 52 weeks and by 3.2% over 13 weeks. 12 of 30 companies we track are beating the S&P 500 on relative strength (how a share price has done against the index over recent months) (2 have no relative-strength reading yet), and 7 of the 28 with a long enough price history are ahead of the industry itself.

A score that ranks each company against the others in its industry. The four parts shown always add up to the total: Growth & earnings (35), Capital efficiency (25), Valuation (20), and Relative strength (20). Missing or old evidence affects only its own part, never as a hidden adjustment.

Cintas Corporation has the strongest current balance of earnings trajectory, business quality, valuation and price confirmation, with 85.3% evidence confidence.

Ranked last: too little evidence (2 companies)

Under 60% of the evidence behind these scores is available, so they rank after every company above, whatever the score.

BUUU Group Limited has the strongest one-year price move in Specialty Business Services at +670.7%. It also leads on relative strength against the S&P 500, at +182.0%. 12 of 30 companies we track are ahead of the index on that measure (2 have no relative-strength reading yet). Every line covers 314 weekly closes through 4 November 2026.

Price and relative strength

Price · same starting point: 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.

RS vs S&P 500: 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.

RS vs sector: The same measure taken against Specialty Business Services 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.

Aramark has the highest Revenue among the 30 Specialty Business Services companies compared here, at $19,845 million. Amentum Holdings, Inc. is next at $14,130 million. Resolute Holdings Management, Inc. has the highest Revenue growth at the 100% top of the scoring scale, so level and change sit with different companies.

What the numbers say: Aramark is the largest at $19,845 million, 40.4% ahead of Amentum Holdings, Inc. Resolute Holdings Management, Inc.'s growth is capped at 100% on the scoring scale; the full change over the last 12 months is 159.3% from a $1,120 million base, with 9 reported quarters out of the last 20. Fast growth from a smaller base is not yet the same as proven size.

What this means: Aramark is the size to compare against; Resolute Holdings Management, Inc. is the one growing fastest. The faster grower has to keep that growth and turn it into margin and returns before it counts as more than a fast start.

This conclusion weakens if: Aramark's growth falls below Resolute Holdings Management, 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.

All-company data · latest reported quarter

In every all-company table on this page, each figure is the company’s latest single reported quarter. The rankings above them use trailing-twelve-month or current-market values, so a company can legitimately show a different number in each.

Revenue shows both size and speed. A large company can absorb shocks and pay for wide distribution; faster growth can mean market-share gains, new capacity or stronger demand. The best sign is usually growth that lasts without hurting margins and returns.

Copart, Inc. has the highest OPM among the 30 Specialty Business Services companies compared here, at 32%. BlackSky Technology Inc. has the highest Margin change at +37.7 percentage points, so level and change sit with different companies. 30 of 30 companies report a comparable reading, the latest through Sep 2026.

What the numbers say: Copart, Inc. leads opm at 32%; BlackSky Technology Inc. leads margin change at +37.7 percentage points.

What this means: Copart, Inc. sets the level to compare against; the company improving fastest needs another report to confirm the change.

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.

Cintas Corporation has the highest Net profit among the 30 Specialty Business Services companies compared here, at $2,054 million. Thomson Reuters Corporation is next at $1,662 million. UL Solutions Inc. has the highest Profit growth at 54.4%, so level and change sit with different companies. 27 of 30 companies report a comparable reading, the latest through Sep 2026.

What the numbers say: Cintas Corporation earns the most, $2,054 million of profit over the last 12 months, 23.6% above Thomson Reuters Corporation. UL Solutions Inc. shows 54.4% growth from a profit base of $505 million. A fast rate from a small base matters less than a large profit that keeps coming.

What this means: Cintas Corporation sets the level to compare against; the company improving fastest needs another report to confirm the change.

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.

RELX PLC has the highest ROCE among the 30 Specialty Business Services companies compared here, at 36.1%. Cintas Corporation is next at 34.3%. LegalZoom.com, Inc. has the highest ROCE change at +9.9 percentage points, so level and change sit with different companies. 30 of 30 companies report a comparable reading, the latest through Jun 2026.

What the numbers say: RELX PLC leads ROCE at 36.1%, 1.8 percentage points above Cintas Corporation. A high return reported once may be one good year; a high return reported year after year shows a lasting business.

What this means: RELX PLC sets the level to compare against; the company improving fastest needs another report to confirm the change.

This conclusion weakens if: The next two comparable reports reverse the current roce change signal.

ROCE asks how much operating return the business earns on the capital employed. Direction matters, but a single exceptional year should not be mistaken for durability.

Maximus, Inc. has the lowest PEG among the 30 Specialty Business Services companies compared here, at 0.31×. ABM Industries Incorporated is next at 0.33×. Global Payments Inc. has the lowest P/E at −21.2×, so level and change sit with different companies. 15 of 30 companies report a comparable reading, the latest through Jun 2026.

What the numbers say: Maximus, Inc. has the lowest comparable PEG at 0.31×, 6.1% below ABM Industries Incorporated. That would need today's multiple, the company's own history and steady growth to agree.

What this means: A low valuation is a reason to look closer at the business, not a conclusion on its own.

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 worked out the same way every time, as the P/E on the last 12 months of reported earnings divided by that growth rate, never on expected earnings. 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.
