ADF Test Applications

Assumption

The Augmented Dickey-Fuller test operates on the premise that a financial time series is stationary, meaning its statistical properties remain constant over time. Traders utilize this framework to determine if crypto asset prices or derivatives premiums exhibit mean-reverting behavior rather than random walks. Confirming this stationarity is essential before applying mean-reversion strategies, as non-stationary data leads to spurious regressions and significant capital risk.
