MRSH vs WTW: Which Is the Better Buy in 2026?
Last updated August 2026
Short answer
MRSH is the larger of the two ($90.52B market cap): the incumbent the market prices for continued execution (16.63x forward earnings, beta 0.60). WTW is the smaller challenger ($31.20B), priced similarly on forward earnings (14.82x): more room to run, but more to prove. The real question is which set of drivers you believe, and whether owning one (or both) leaves you over-concentrated.
MRSH vs WTW: the tie-breaker metrics
Same yardstick, side by side (as of August 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.
| Metric | MRSH | WTW | What it tells you |
|---|---|---|---|
| Market cap | $90.52B | $31.20B | Size. The larger name is the incumbent; the smaller has more room to grow and more to prove. |
| Forward P/E | 16.63 | 14.82 | Valuation on next year's expected earnings, the same yardstick for both. Lower is cheaper for that growth; higher means the market is paying up. |
| Trailing P/E | 23.16 | 20.79 | Valuation on the last 12 months. A big drop from trailing to forward means the market expects earnings to jump, so more growth is already in the price. |
| Beta | 0.60 | 0.44 | Volatility vs the market. Above 1 swings harder than the index; below 1 is steadier. Higher beta means bigger drawdowns to hold through. |
| Price vs 52-week range | 58% of range | 85% of range | Where today's price sits between the 52-week low and high. Near the high is momentum with less margin of safety; near the low is out of favor or a discount, depending on why. |
| Price / book | 5.97 | 4.06 | How much you pay over book value. Very high can signal an asset-light, high-return business or a rich price. |
Before you buy: how MRSH and WTW affect your concentration
The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. MRSH and WTW share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.
This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined MRSH and WTW exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker. Walnut is not an investment adviser.
What does Marsh (MRSH) do?
Marsh (ticker MRSH, formerly Marsh & McLennan Companies under MMC) is a global professional services firm built around two segments. Risk and Insurance Services houses Marsh, the world's largest insurance brokerage, and Guy Carpenter, a leading reinsurance broker. The Consulting segment houses Mercer, a large health, wealth, and career consultancy, and Oliver Wyman, a management consulting brand. Together these businesses employ roughly 90,000 people and generate the bulk of revenue from recurring commissions and advisory fees tied to commercial insurance placement, reinsurance, retirement, and workforce advisory work.
What does Willis Towers Watson (WTW) do?
Willis Towers Watson (Nasdaq: WTW) is a global professional services firm built around two core lines: Risk and Broking (insurance brokerage, risk advisory, and reinsurance-adjacent services) and Health, Wealth and Career (employee benefits, retirement and pension consulting, compensation, and investment advice). The Health, Wealth and Career segment is the larger contributor at roughly 60% of revenue, while Risk and Broking has been the faster-growing engine. The company earns recurring fees and commissions from corporate clients ranging from small businesses to multinationals, which gives revenue a relatively stable, subscription-like character.
MRSH vs WTW: how do they differ?
Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.
- MRSH drivers: Insurance brokerage scale and pricing cycle; Diversified consulting through Mercer and Oliver Wyman.
- WTW drivers: Risk and Broking momentum; Margin expansion.
Which fits which kind of investor
A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: As an insurance broker, revenue is tied to the commercial insurance pricing cycle, and a prolonged soft market with falling premium rates would slow commission growth. For WTW, wTW is a mature business with mid-single-digit organic growth, so any deceleration in Risk and Broking or benefits demand can pressure a valuation that already assumes steady execution.
MRSH or WTW: which should you pick?
Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick MRSH if you believe its drivers more; WTW if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the MRSH and WTW guides.
MRSH vs WTW: the full fundamentals
MRSH. Marsh generated roughly $27 billion in trailing revenue with high-single-digit organic growth and expanding adjusted margins. It trades around a low-20s price to earnings multiple, a premium that reflects its recurring fee revenue and steady compounding rather than rapid growth. The next quarterly report is expected in late July 2026.
WTW. As of July 2026 WTW traded around $289 per share with a market cap near $27 billion and a forward P/E under 15, a moderate multiple for a stable advisory and broking franchise. Full-year 2025 revenue was about $9.7 billion with net income around $1.6 billion, and Q1 2026 revenue grew roughly 8% to $2.41 billion with adjusted EPS up 19%. The stock is valued more like a steady cash compounder than a high-growth name.

FAQ
What is the difference between MRSH and WTW?
+
Marsh (ticker MRSH, formerly Marsh & McLennan Companies under MMC) is a global professional services firm built around two segments. Willis Towers Watson (Nasdaq: WTW) is a global professional services firm built around two core lines: Risk and Broking (insurance brokerage, risk advisory, and reinsurance-adjacent services) and Health, Wealth and Career (employee benefits, retirement and pension consulting, compensation, and investment advice). They show up together because they share investment themes, but they are different businesses, so the better fit depends on which thesis you are expressing.
Is MRSH or WTW the better stock?
+
Neither is universally better. MRSH is the larger incumbent; WTW is the smaller challenger and looks cheaper on forward earnings. Walnut is informational, not investment advice. Compare what each does, the tie-breaker metrics above, and the risks, then decide which fits your thesis and what you already own.
Which is cheaper, MRSH or WTW?
+
On forward P/E (as of August 2026), MRSH trades at 16.63x and WTW at 14.82x, so WTW is the cheaper of the two on next year's expected earnings. A lower multiple is not automatically the better buy: a richer valuation can be justified by faster growth, and a lower one can reflect real risk. Weigh the multiple against how fast each business is compounding.
Should you own both MRSH and WTW?
+
Because they share themes, owning both concentrates you in that theme. That can be intentional (a focused bet) or accidental (less diversification than it looks). Walnut can show your combined exposure across both, and whether adding either over-concentrates you, before you buy.
What are the risks of MRSH vs WTW?
+
MRSH: As an insurance broker, revenue is tied to the commercial insurance pricing cycle, and a prolonged soft market with falling premium rates would slow commission growth. The consulting businesses are more cyclical and can weaken when corporate clients cut discretionary project and benefits spending. The stock trades at a premium valuation (a low-20s price to earnings multiple), so disappointing organic growth or margins could compress the multiple. Large acquisitions carry integration and goodwill risk, and the firm faces professional liability and regulatory exposure across many jurisdictions. Currency swings also affect reported results given the global footprint. WTW: WTW is a mature business with mid-single-digit organic growth, so any deceleration in Risk and Broking or benefits demand can pressure a valuation that already assumes steady execution. Much of the earnings-per-share growth depends on margin gains and buybacks rather than revenue, which limits the cushion if margins stall. The firm is smaller and historically lower-margin than Marsh McLennan and Aon, leaving it more exposed to competitive pressure on talent and pricing. Insurance brokerage revenue is sensitive to insurance pricing cycles and macro conditions that affect client budgets and payrolls. Large advisory and consulting firms also carry integration, litigation, and reputational risks tied to complex client engagements.
