Billionaire Bill Ackman Has 11% of His Hedge Fund in Visa and Mastercard. 3 Reasons Why the Famed Investor Is Bullish on These S&P 500 Stocks

Pershing Square initiated positions in Visa and Mastercard during the second quarter; together, the stocks represent 11.4% of the hedge fund’s portfolio. The firm cites strong network effects, substantial growth runway—with card payments accounting for about half of addressable global consumer spending—and high operating margins: Visa averaged 67% over the past five years versus Mastercard’s 58%. Pershing Square expects both companies to deliver high-teens annualized EPS growth over the next three to five years.

Analysis

Quality is not the same as mispricing

The investable question is whether digital-payment growth converts into durable incremental earnings—not whether card usage still has room to expand. Conversion can be slower or less profitable where cash displacement requires merchant incentives, local infrastructure, or lower-cost account-to-account alternatives. Digital wallets are not automatically disintermediators if transactions still use card rails, but stronger routing choices and regulation of fees could shift bargaining power toward merchants and reduce network economics.

Pershing Square’s position is a useful signal of institutional confidence, not independent confirmation of the stated high-teens EPS trajectory. That growth expectation is the key underwriting risk: if results or guidance merely show transaction growth without comparable earnings growth, a premium multiple could compress. No valuation, current consensus, or earnings-revision data are provided, so the article alone does not establish that either stock is cheap.

Near term, the stake may support sentiment but is unlikely to change fundamentals. Over 1–3 months, watch reported payment volumes, cross-border trends, pricing, expense growth, and guidance revisions. Over 6–18 months, the main contest is whether digital conversion outpaces fee pressure and alternative payment rails. The thesis weakens if earnings growth falls materially short of the high-teens expectation, or if regulation or routing shifts demonstrably constrain pricing.

Key Decisions for Investors

• Do not chase the recent appreciation on this endorsement alone. Treat V and MA as a quality-growth watchlist; consider staged long exposure on a broad-market pullback only after checking current valuation and forward earnings revisions.
• If establishing exposure, use an equal-weight V/MA basket rather than making a relative-value call unsupported by comparative valuation or growth data. Size it against the risk that both share the same regulatory and payment-substitution shocks.
• Before adding, verify company-reported volume and cross-border growth alongside operating-expense trends and guidance. Strong volumes without earnings follow-through would falsify the claimed growth-to-EPS transmission.
• Monitor regulatory fee or routing changes and adoption of account-to-account payment systems as downside catalysts; merchant acceptance costs and competition could benefit merchants even if consumer digital-payment activity continues to rise.
