Abstract: Asset pricing traditionally works with information aggregated over horizons, however investors preferences are horizon-specific. Decomposing returns, and risk factors to components representing individual horizons may hence provide valuable insights into pricing mechanisms of investors. With increasing size of factor-investing literature, the number of factors approximating risk, and possibly explaining the cross section of returns is growing rapidly. However, most of the factors perform poorly in subsequent out-of-sample testing. Therefore, attention should be turned to theory-based factors approximating the risks such as moments of the return distribution that are found to be priced empirically. We derive an asset pricing model that contains second, third and fourth centralized moments of returns on aggregate wealth decomposed to short-run, medium-run, and long-run components. The horizon-specific model outperforms CAPM, and Four-Moment CAPM in explaining the mean returns of S\&P 500 stocks, and Exchange Traded Funds. Moreover, the derivation assuming a general utility function of wealth allows us to quantify the discrepancies in investors' risk tastes like risk aversion or prudence in different horizons.
