Mark Hulbert: Dow Double-Digit Odds Stay at 49% Baseline, Bitcoin (BTC) in Focus

Crypto News

Mark Hulbert, a longtime market commentator, argues that three consecutive years of double-digit gains for the Dow Jones Industrial Average have not increased the statistical probability of a pullback. The argument directly confronts a popular narrative on Wall Street that the rally's age alone makes a downturn statistically overdue. Drawing on 129 years of Dow data extending back to the late 1890s, Hulbert puts the historical baseline chance of another double-digit year at 49%, a level that has barely moved even after multiple strong years. He calls the streak-based crash narrative the gambler's fallacy, the same reasoning error behind coin-flip superstitions: a coin that lands heads several times in a row is still 50% likely to land heads again, and a market that has risen sharply is not mathematically “due” for a decline. Hulbert stresses that his model is built entirely on trailing returns, so it does not incorporate other risks such as stretched valuations in U.S. equities. His framework treats the market as a process without memory, at least where annual return streaks are concerned. His bottom line is that the odds of the Dow finishing 2026 with a double-digit gain are no better and no worse than in any other year. For crypto traders, the distinction has become increasingly relevant because Bitcoin (BTC) and the wider altcoin market have traded in close sympathy with equity risk appetite. The Dow's extended run has lifted the index to repeated all-time highs, yet the probability framework remains stubbornly flat. A pullback that is treated as inevitable could spill into digital assets through risk-off selling, but Hulbert's data suggest the streak itself provides little statistical support for that trigger.

A separate layer of the same analysis converts that flat baseline into a time-bound crash probability. The framework, developed by researchers at Harvard University and the University of Hong Kong, uses trailing two-year returns to estimate the likelihood of a severe drawdown. State Street Markets, working with the Harvard researchers, applies that model to current conditions, and its output puts the probability of a 40% drop in the Dow over the next two years at 19%. That is below the five-year average of 26%, meaning crash odds are currently running below normal by this measure. The probability estimate, in other words, is a risk measurement rather than a market call. Even with the streak, the model still assigns nearly one-in-five odds to a severe decline. The model is explicitly backward-looking, and Hulbert does not present it as a complete risk dashboard; instead, he frames it as a guard against the impulse to treat a long rally as a ticking clock. Hulbert is careful to flag the model's limits: it reflects trailing returns only and does not account for stretched valuations or other fundamental risks. Wall Street itself remains divided. Fundstrat's Tom Lee has argued for a correction before additional upside, while JPMorgan and CFRA have raised their S&P 500 forecasts, signaling confidence that the rally can continue. Some traders see echoes of the dot-com bust in the recent rotation among AI-related stocks, though Hulbert treats that as a separate issue from the streak-based call. Hulbert does not attempt to model that AI rotation in his trailing-returns framework. For crypto investors, the distinction between a mechanical pullback and a fundamental repricing is material, because a valuation-driven downturn tends to hit high-beta assets such as Bitcoin and altcoins much harder through margin calls and risk-off flows. The all-time highs reached during the equity run have done little to alter the model's central estimate.

Taken together, the two layers of analysis point to one theme: extended winning streaks are not a reliable predictor of a collapse. The primary-source anchor is the 129-year Dow dataset and the Harvard/Hong Kong framework operationalized by State Street Markets; both show baseline probabilities that stay constant. For Bitcoin (BTC), the implication is indirect. If a stock-market reversal is not statistically imminent simply because the Dow has run for three years, the crypto market's reflexive assumption of a looming risk-off shock deserves scrutiny. In our reading, Bitcoin remains more sensitive to liquidity conditions and regulatory catalysts than to streak-based narratives. The 49% baseline and 19% two-year crash probability are reference points, not guarantees that volatility has been cancelled.
