Assessing the fundamental value of a firm is a difficult task. Theoretically, the market price is exogenous and should not be used in the estimation. We performed a simple experiment to pinpoint whether price is used in fundamental value calculation. Subjects were given similar information on a firm. In the first/control situation, no price was submitted. In the second situation, the actual price was submitted to them. In the third one, a manipulated, overvalued price was provided. We find that the price provided, whatever it is, proves to have a clear impact on the subjects' estimations. This is consistent with the anchoring-and-adjustment hypothesis of fundamental assessment and has implications for a better understanding of financial bubbles.
