AMG vs TROW: Which Is the Better Buy in 2026?

Same yardstick, side by side (as of September 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.

Reading it: AMG is the cheaper of the two on forward earnings, but cheaper is not the same as better. Pair the valuation with growth (how far the forward P/E sits below the trailing P/E) and risk (beta) before you decide.

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. AMG and TROW 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 AMG and TROW 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.

Affiliated Managers Group operates a multi-boutique model: instead of running money itself, it takes long-term equity stakes in independently managed investment firms across equities, fixed income, liquid alternatives, and private markets. Each affiliate keeps operational and investment autonomy while AMG shares in its management and performance fees and provides growth capital, distribution, and strategic support. As of Q1 2026 the affiliate network managed record assets under management of roughly $882 billion, with about $148 billion in private markets and $261.5 billion in liquid alternatives, and those alternative strategies now drive the majority of earnings.

T. Rowe Price Group is a Baltimore-based investment management firm and one of the largest active asset managers in the world, with assets under management around $1.71 trillion at the end of the first quarter of 2026. It manages money across mutual funds, exchange-traded funds, separately managed accounts, and retirement and target-date strategies, serving both individual investors and large institutions. Its business model is simple to understand: it charges fees as a percentage of the assets it manages, so revenue tracks two things closely, the market level of those assets and the net flow of client money in or out.

Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.

• AMG drivers: Shift toward alternatives and private markets; Record AUM and net inflows.
• TROW drivers: Active-to-passive flow pressure; ETFs, SMAs, and target-date growth.

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: AMG's revenue is tied to market levels and net flows, so a market drawdown or a shift back to outflows would compress fees quickly. For TROW, the dominant risk is the structural shift toward passive investing, which keeps pulling money out of active equity funds and pressures both fee rates and asset levels over time.

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 AMG if you believe its drivers more; TROW 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 AMG and TROW guides.

AMG. AMG trades at a low-teens earnings multiple, reflecting the market's discount for asset managers exposed to fee compression despite strong recent growth. Q1 2026 delivered record AUM near $882 billion, roughly $545 million of consolidated revenue, and Economic EPS up about 58% year over year, led by alternatives. Valuation multiples and per-share metrics vary by source and date.

TROW. Figures are approximate and tied to the asOf date; verify live numbers before acting. For an active asset manager, the market often prices persistent outflows into a lower multiple, so a cheap-looking valuation can reflect real concern about shrinking active fund assets rather than a bargain. The dividend yield tends to look attractive precisely when investors are most worried about flows and fee pressure, so weigh yield against the durability of the underlying business.

Headline figures (approximate, JULY 2026): AMG shows assets under management (q1 2026) ~$882B, consolidated revenue (q1 2026) ~$545M, revenue (ttm, approx) ~$2.1B, economic eps growth (yoy, q1 2026) ~58%; TROW shows business model Fee-based active asset manager; revenue is a percentage of assets under management, so results track market levels and net client flows, assets under management Roughly $1.71 trillion at the end of Q1 2026, up year over year on stronger markets despite outflows, recent earnings Q1 2026 adjusted earnings per share rose in the low double digits from a year earlier and came in ahead of analyst expectations, client flows Net outflows of roughly $13.7 billion in Q1 2026, concentrated in US growth equity, partly offset by ETF, SMA, and target-date inflows.

AMG and TROW are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme. Walnut can show your combined AMG and TROW exposure against your real portfolio. It is not an investment adviser.
