Abstract: In this paper we consider the sequential equilibrium of multistage chainstore games with imperfect information. We point out that the consistent belief in this sequential equilibrium would be avoided in terms of inconsistency which turns out that the incumbent must be a weak firm. Rational player would not choice such strategy. In this case Selten's examination of the perfectness concept for equilibrium points in extensive games would be invalid.
