U.S. investors are setting themselves up for disappointment, with expectations for portfolio returns that dramatically outpace what history says is achievable.
According to research highlighted by MarketWatch columnist Mark Hulbert, the average American investor expects their portfolio to beat inflation by 12.6% annually over the long term.
That figure alone is striking, but Hulbert’s analysis makes clear that for many individual investors, expectations run even higher than that average suggests.
The hard reality is that 12.6% above inflation is almost certainly more than double what any honest reading of stock market history would support as realistic.
The U.S. stock market has delivered a total return above inflation of just 6.1% annualized going all the way back to 1793, a track record spanning more than two centuries of economic booms, busts, wars, and recoveries.
That long-run figure of 6.1% is not a floor or a pessimistic scenario — it represents the actual historical ceiling that most investors will never reach in their own portfolios.
Hulbert points out that broad-market indexes such as the S&P 500 will, if history is any guide, outperform 90% of investor portfolios over any meaningful stretch of time.
That statistic alone should give pause to anyone who believes they will consistently beat the market through stock picking, newsletter subscriptions, or actively managed mutual funds.
The question Hulbert poses is a pointed one: how likely is it that over the next several decades, any individual investor will do better than both the best investment newsletter and the best equity mutual fund?
Long-term real returns above 10% annualized are exceedingly rare in the historical record, yet a striking number of American investors have come to treat double-digit, inflation-beating gains as something close to guaranteed.
This gap between expectation and reality has practical consequences, as investors who overestimate future returns may save too little, retire too early, or take on excessive risk chasing yields that history says are unlikely to materialize.
Hulbert, who founded the Hulbert Financial Digest and spent decades tracking the performance of investment newsletters, brings particular credibility to the argument that even professional guidance rarely closes the gap between expectation and reality.
The broader lesson is a familiar but persistently ignored one: compounding modest, realistic returns over long periods produces genuine wealth, while chasing inflated expectations often produces the opposite.
