We explore the way rational subjective expectations are translated into asymmetric distributed rates of return. Special emphasis is placed upon behavioural phenomena such as over- and underreaction, narrow framing, and bounded rationality. The mathematical model of investors’ expectations extrapolation based on Gram — Charlier expansion is suggested and proved empirically by retrospective investment strategies testing.
