US Market Periods — Best

Some retirees got extraordinarily lucky with their timing. These video shorts spotlight the best 30-year periods in US market history — stretches where a balanced portfolio didn’t just survive, it multiplied wealth far beyond what most planners would project. Starting from 1871, each simulation follows a real portfolio through 30 years of actual stock returns, bond yields, and inflation. The best periods often coincided with post-war booms, falling interest rates, or technological revolutions that drove decades of above-average growth. These aren’t cherry-picked success stories. They’re the upper tail of over 120 overlapping 30-year windows, showing you the ceiling of what history has actually delivered. Understanding the best cases matters because they set realistic expectations — and reveal how much of retirement success comes down to the era you happen to retire in.
