Time horizon dimensions are added to asset pricing theory. Single period, static, arbitrage pricing theory (APT) describes single period risk with long horizon contributions in the frequency domain. Mean-reversion risks correspond to horizon variances. Mean-reversion risk is measured using the...

Independently from the econometric approach used, all models produce quick to estimate forward-looking risk measures that do not depend from the amount...
