What is Fundamental Backtesting?

While technical backtesting uses price and indicators, fundamental backtesting evaluates strategies based on business or network metrics like:

Earnings, revenue growth, and valuation ratios (stocks)

On-chain metrics like active addresses or transaction volume (crypto)

Backtesting these inputs helps you understand how buying based on fundamentals would have performed over time.

Example:

Buy crypto projects with consistent wallet growth and active dev activity

Backtest performance over 1–3 years

 

Why Backtesting Fundamentals Matters

✅ Separates narrative from results — test the actual historical impact of your thesis
✅ Builds investor confidence — reinforces decisions with data
✅ Finds what truly matters — identifies which metrics correlate with price growth
✅ Improves timing — reveals better entry points or valuation windows
