Signal Decay Calculator

Enter the IC of your alpha signal at multiple forward-return horizons. The tool fits an exponential decay model and estimates the signal half-life and optimal rebalancing frequency.

How it works: The tool takes the natural log of each IC observation and fits a line — ln(IC) = ln(IC₀) − λh — using ordinary least squares. From the slope λ it derives the half-life t½ = ln(2)/λ and a rebalancing guideline based on the point where IC falls below 75% of its peak. Only positive IC rows are used in the regression.

Signal IC at Multiple Horizons

Enter the Information Coefficient (IC) of your signal at each forward-return horizon. Only positive IC values are used in the fit.
