The relevance of professional asset managers can be best highlighted by the role assigned to them in the finance theory.

In that case, a security’s actual price reflects its true “fundamental value” – the discounted sum of expected future cash flows. This prominent Efficient Market Hypothesis (EMH), differentiating the weak-, semistrong- and strong-form market efficiency, has been formulated by Fama (1970). Moreover, in efficient markets there are no unexploited profit opportunities (“no free lunch”). The early work by Friedman (1953) suggests that even if not all investors were fully rational, the group of rational investors would quickly eliminate any deviation from a security’s fundamental value, i.e. a mispricing, caused by irrational traders.
