Most real world market participants are professional portfolio managers (PPM) managing money for third parties (e.g. mutual funds, pension funds). Those third parties (investors) usually lack specialized knowledge and therefore may evaluate the PPM performance based on his past results (Performance Based Evaluation - PBE). Under these assumptions, we develop a limits-to-arbitrage model which considers that professional investment is conducted by a relatively small number of highly specialized PPM using other people’s capital. In a deductive way, we reach four propositions assessing the effectiveness of momentum strategies. Specifically we show that in a market with PPM subject to positive (negative) PBE, returns would have positive (negative) autocorrelation which is not inconsistent with profitable momentum-based investment strategies.
