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 35% behind S&P 500. Earnings across its companies fell 1% on average over the last four reported quarters. It has been ahead of S&P 500 on a rolling three-month view for 20 weeks running.

Price down, no fundamental support. 7 of the 14 companies with a long enough price record ahead of S&P 500 by 5% or more over three months. 1 is 20% or more behind over a year while earnings grew 20% or more.

Ahead of S&P 500 on the three-month view for 20 weeks running; 13 of the 14 companies in the industry index above their 200-day average (5 more than four weeks earlier); 7 of those 14 ahead of S&P 500 by 5% or more over three months (2 more than four weeks earlier); earnings rising at 6 of the 14 that report earnings.

Ahead of S&P 500 for 20 weeks running and +10.8% over a year, with 5 → 7 of 14 stocks participating. Earnings mixed, 6 of 14 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 14 of its 15 companies (the 1 with too short a price record are ranked in the scorecard but cannot sit in this line). 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.

Insurance Brokers has done worse than the S&P 500 by 3.1% over the last 52 weeks. Over 13 weeks the gap is a lead of 6.2%. CorVel Corporation is the strongest against the sector itself at +14.5%.

Insurance Brokers has done worse than the S&P 500 by 3.1% over 52 weeks, but is 6.2% ahead over the last 13 weeks. 8 of 15 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 5 of the 13 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.

TWFG, Inc. has the strongest current balance of earnings trajectory, business quality, valuation and price confirmation, with 76% evidence confidence.

Ranked last: too little evidence (3 companies)

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

Accelerant Holdings has the strongest one-year price move in Insurance Brokers at +57.0%. CorVel Corporation leads on relative strength against the S&P 500, at +27.0%. 8 of 15 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 Insurance Brokers 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.

Marsh & McLennan Companies, Inc. has the highest Income among the 15 Insurance Brokers companies compared here, at $28,459 million. Aon plc is next at $17,577 million. Ethos Technologies Inc. has the highest Income growth at 82.9%, so level and change sit with different companies. 15 of 15 companies report a comparable reading, the latest through Sep 2026.

What the numbers say: Marsh & McLennan Companies, Inc. is the largest at $28,459 million, 61.9% ahead of Aon plc. Ethos Technologies Inc.'s growth is 82.9% from a $587 million base, with 10 reported quarters out of the last 20. Fast growth from a smaller base is not yet the same as proven size.

What this means: Marsh & McLennan Companies, Inc. is the size to compare against; Ethos Technologies 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: Marsh & McLennan Companies, Inc.'s growth falls below Ethos Technologies Inc.'s for two consecutive comparable reports while operating margin also compresses.

For lenders, reported income is used instead of industrial-company sales. Growth is compared year-on-year.

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.

Marsh & McLennan Companies, Inc. has the highest Net profit among the 15 Insurance Brokers companies compared here, at $4,123 million. Aon plc is next at $3,978 million. Willis Towers Watson Public Limited Company has the highest Profit growth at the 100% top of the scoring scale, so level and change sit with different companies.

What the numbers say: Marsh & McLennan Companies, Inc. earns the most, $4,123 million of profit over the last 12 months, 3.6% above Aon plc. Willis Towers Watson Public Limited Company shows at least 100% on the scoring scale (972.1% in full) growth from a profit base of $1,576 million. A fast rate from a small base matters less than a large profit that keeps coming.

What this means: Marsh & McLennan Companies, 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 profit growth signal.

Net profit is ranked only where the comparison base is economically meaningful. Loss-to-profit flips are shown but do not win the growth table.

No company in this Insurance Brokers comparison reports a funding base figure this section can compare, so the Deposits rank is empty. On Borrowings, Marsh & McLennan Companies, Inc. is highest at $22,332 million, across 15 of 15 companies with a usable reading.

What the numbers say: There is not enough comparable evidence to name a reliable deposits leader.

What this means: The current leader 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 borrowings signal.

For banks, debt is operating funding rather than industrial leverage. Deposits and borrowings are therefore shown as funding-base levels; asset quality, funding cost and liquidity determine whether that funding is attractive.

Deposits is left out: no company here reports it on a comparable basis.

Deposit scale can lower funding risk, while rising wholesale borrowings can change cost and liquidity. Asset quality and margins decide whether the funding base creates value.

Neptune Insurance Holdings Inc. has the highest ROA among the 15 Insurance Brokers companies compared here, at 70.8%. CorVel Corporation is next at 15.4%. Goosehead Insurance, Inc. has the highest ROA change at +5.2 percentage points, so level and change sit with different companies. 15 of 15 companies report a comparable reading, the latest through Sep 2026.

What the numbers say: Neptune Insurance Holdings Inc. leads roa at 70.8%; Goosehead Insurance, Inc. leads roa change at +5.2 percentage points.

What this means: Neptune Insurance Holdings 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 roa change signal.

ROA is the cleanest first comparison for lenders because the balance sheet is the operating asset.

Goosehead Insurance, Inc. has the highest ROE among the 15 Insurance Brokers companies compared here, at 461.2%. Aon plc is next at 50.8%. The same company also has the highest ROE change, at +268.7 percentage points. 14 of 15 companies report a comparable reading, the latest through Jun 2026. Its ROE series carries 4 reported observations across the 20-quarter window.

What the numbers say: Goosehead Insurance, Inc. leads both roe at 461.2% and roe change at +268.7 percentage points.

What this means: Goosehead Insurance, 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 roe change signal.

ROE shows the return to shareholders, but should be read with asset quality and leverage.

No company in this Insurance Brokers comparison reports gross NPA on a comparable basis, so there is nothing to rank here, 0 of 15 companies have a usable current reading. The section is shown rather than removed so an unavailable metric is not mistaken for one that was quietly left out. Filings were read through Sep 2026.

Lower gross NPA is better. Improvement means the ratio is falling, so ranks are intentionally inverted.

SelectQuote, Inc. has the lowest P/BV ÷ ROE among the 15 Insurance Brokers companies compared here, at 0.01×. TWFG, Inc. is next at 0.07×. Neptune Insurance Holdings Inc. has the lowest P/BV at −17.7×, so level and change sit with different companies. 10 of 15 companies report a comparable reading, the latest through Jun 2026.

What the numbers say: SelectQuote, Inc. has the lowest comparable P/BV ÷ ROE at 0.01×, 85.7% below TWFG, Inc. 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/bv signal.

Banks are compared on P/BV and P/BV÷ROE, not PEG. A lower figure is better only if loan quality and returns stay strong; a low price against book value while bad loans are rising is not a good sign by itself.

This Insurance Brokers comparison names 6 specific ways its own evidence can mislead, all listed below. All 15 companies here report on comparable dates, so no rank carries a stale marker. 2 of the 7 ranked sections have fewer than three usable current readings. A high growth rate can still come from a very small starting figure.

Keep these limits visible

• A high growth rate can come from a very small starting figure. The page keeps level and change separate for that reason.
• A high ROE can come from heavy borrowing. It is best read beside ROA and loan quality.
• The 4-Factor Sector Score ranks published data only. Management quality, upcoming events and risks are not part of it.
• An “all companies” line chart preserves completeness, but rank changes should be checked against reporting dates before drawing a conclusion.
• Banks and lenders are not forced through operating-margin or ROCE comparisons; missing lender-specific fields remain visibly missing.
• Thin comparisons: Funding base, Asset quality have fewer than three usable current readings.

This comparison is built from the reported filings of 15 Insurance Brokers 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 4 November 2026.

These 21 answers restate the Insurance Brokers comparison above in question form. Every one is computed from the same 15 companies and the same reported filings as the rankings and charts, current through Sep 2026. Price and relative-strength answers run through 4 November 2026. Nothing here is estimated, and none of it is a recommendation.
