Portfolio stress test

What would have happened to your money if you had invested right before a crisis. Five real crashes of the last 25 years — on actual prices, in US dollars.

S&P 500 (the rest)
📊 Data: Yahoo Finance, month-end values since August 2000. S&P 500 with dividends reinvested, bonds — a broad US bond market fund (VBMFX) including payouts, gold — exchange price. The portfolio is rebalanced to the set weights once a year. A single lump sum, with no top-ups, taxes or fees.
⚠️ Every scenario starts at the worst moment — the peak before the fall. The data is monthly: within a month the drops were deeper (in March 2020 stocks were down about a third, but a fifth at month end). The next crisis does not have to look like the past ones.

How to read the result

The key number in each card is how much money would be left at the lowest point. Not a percentage but an amount: that is what you would have seen in your broker app. Next to it — how many months the fall lasted and how long you would have waited to see your starting amount again.

On the chart the dashed line is the amount invested, and the red area is the time you spent in the red.
