How We Calculated This

We looked at how VOO actually moved every single day from 2021-02-23 to 2026-02-18 (1,252 trading days). Then we randomly shuffled those daily moves and stitched them together to create 5,000 possible versions of the next 12 months. The "Bad Year" is what happened in the worst 20% of those versions, "Most Likely" is the middle, and "Good Year" is the best 20%.

This technique is called Monte Carlo simulation — the same method used by hedge funds, asset managers like Vanguard and BlackRock, and institutional risk teams worldwide. We're not predicting the future; we're showing you the range of outcomes that history suggests is possible.

Understanding VOO's Risk Profile

Nobody can predict the stock market with certainty. But we can study historical behavior to understand the range of possibilities. Using 1,252 days of real VOO price data, we ran 5,000 "what if" scenarios to map out what the next 12 months could look like based on past patterns.

Think of it like this: if you could replay the next year 5,000 times with different market conditions (based on how VOO actually behaved in the past), here's what you'd see.

What the Numbers Mean for VOO

  • 21 out of 100 times, you'd lose money. That means if you invest $10,000 in VOO today, there's a 21% chance you'll have less than $10,000 in 12 months.
  • In a bad year, you could lose up to 1%. That's $92 gone from a $10,000 investment.
  • In a good year, you could gain up to 31%. Your $10,000 could grow to $13,140.
  • Compared to the S&P 500: VOO is less risky than just buying an index fund. The S&P 500 has a 23% chance of losing money vs VOO's 21%.
