Understand investing through history

Markets can feel complicated. The goal here is simple: use real historical data to understand how investing has behaved through different market environments.

No predictions. No hype. Just perspective.

Start with a question

Each of these opens a tool that answers it with historical data.

Put market moves in perspective

A single good or bad year can feel important when you are living through it. History gives it context.

A few investing concepts worth understanding

These terms appear throughout the tools.

Total return
Total return includes both price changes and income such as dividends.
Volatility
Volatility measures how much investment returns have moved up and down over time.
Drawdown
A drawdown is the decline from a previous market high to a later low.
Recovery
Recovery measures how long it took an investment to return to its previous high after a decline.
Correlation
Correlation shows how closely two investments have historically moved together.
Diversification
Diversification means spreading investments across different assets rather than depending heavily on one area of the market.
CAGR
Compound annual growth rate is the annualized rate at which an investment grew over a period of time.

Keep perspective

Historical data cannot tell us exactly what markets will do next.

It can help us understand what investors have experienced before — growth, declines, volatility, recoveries, and changing market leadership.

Use the tools to explore the history, compare scenarios, and better understand the risks behind an investment decision.
