3 Stocks That Have Compounded Wealth for Decades. History Suggests the Next Decade Will Not Be Different

Compounding is boring until you look at the receipts. Three businesses have quietly turned a decade of reinvested cash flow into life-changing returns, and the engines that produced those returns are still running. Our filter for a genuine compounder is narrow: durable revenue and earnings growth, expanding margins, high returns on capital, a moat that widens with scale, disciplined shareholder returns, and a reinvestment path into credible next-decade growth. Only three names clear that bar today.
Past compounding does not guarantee future compounding, and at mega-cap scale the law of large numbers is real. The structural setups below suggest the next ten years rhyme with the last ten.
No. 3: Mastercard, the Network That Prints Yield
Mastercard (NYSE:MA | MA Price Prediction) has returned 505.86% over the past ten years and 70.45% over the past five. The engine is a payment network with genuine network effects: more issued cards attract more merchants, which attract more switched transactions, which generate more data to fuel value-added services.
Q2 FY2026 landed adjusted EPS of $5.04 versus $4.77 expected, the sixth consecutive beat, on net revenue of $9.28 billion, up 14.1% YoY. Adjusted operating margin expanded to 61.1%. Value-added services net revenue grew 18% currency-neutral, and management repurchased $4.90 billion of stock in the quarter. Forward growth vectors include Mastercard Agent Pay for agentic commerce and the planned BVNK acquisition for stablecoin rails.
Forward risk: interchange regulation and U.S. merchant class litigation remain live. The stock trades at a forward PE of 25x, which prices in continued execution.
No. 2: Amazon, a Retail Flywheel Bolted to the Largest Cloud on Earth
Amazon (NASDAQ:AMZN) has compounded at 531.87% over ten years. The structural advantage is two engines under one roof: a retail flywheel that keeps lowering unit economics for consumers, and AWS, which is now a reinvestment machine for AI infrastructure.
Q2 FY2026 revenue reached $200.61 billion, up 19.6% YoY, with operating income of $27.46 billion, up 43.2%. AWS grew 37% to $42.23 billion, the fastest AWS growth in 18 quarters, at a 39.4% operating margin. AI and custom chips each cleared $25 billion annualized run rates, growing triple-digit percentages. Backlog stood at $496 billion. CEO Andy Jassy said AWS could ultimately be a “trillion dollar annual revenue business for us in time with very appealing accompanying free cash flow and return on invested capital.”
Forward risk: capital intensity. Q2 cash capex was $53.1 billion, and TTM free cash flow turned negative at -$7.6 billion. That buildout also flows to the power, cooling, and networking suppliers behind the data centers, seven of which we profiled in a free AI infrastructure report. Shares are down 5.87% over the past month, trading at a forward PE of 24x.
No. 1: Costco, the Membership Model That Refuses to Break
Costco (NASDAQ:COST) tops the list on a 593.84% ten-year return and the most disciplined engine of the three: a membership flywheel priced to keep members loyal for decades. Management stated the philosophy plainly: “Our goal is to be the first to lower prices and the last to raise them.”
Q3 FY2026 revenue rose to $70.53 billion, up 11.6% YoY, with EPS of $4.93 and net income of $2.19 billion, up 15.2%. Membership fees hit $1.37 billion, up 10.7%. The worldwide renewal rate held at 89.7% and U.S./Canada renewals ticked to 92.2%. Executive members reached 41.2 million, up 9.6%, and drive 75.0% of net sales. Digitally enabled comps grew 21.5%, and site/app traffic climbed 37%. The warehouse footprint is expanding to 928 worldwide today, with 30-plus net new openings targeted annually.
Forward risk: the shares carry a trailing PE of 46x, the richest of the three. Valuation reset risk is real if comps decelerate.
Why the Next Decade Rhymes
The three engines are different by design: a payments network that monetizes every incremental swipe, a retail-and-cloud flywheel reinvesting into AI infrastructure at scale, and a membership warehouse that trades gross margin for renewal rates in the low 90s. Each has produced a decade of compounding through a mechanism that gets stronger with size. Costco tops the ranking because its engine is the most self-reinforcing and least dependent on any single technology cycle.
