Information, noise, market frictions cause investor confidence to influence security prices, leading to a price different from the rational expectations value. This paper presents a simple theoretical model of asset prices where investor confidence is allowed to differ across traders, and across time — depending on observed outcomes. The presence of short-sales constraints causes asset prices to behave asymmetrically: short-run returns display reversal after good news, but momentum after bad news. This changes somewhat if investor confidence varies because of biased self-attribution: good news causes returns to exhibit short-run momentum and long-run reversal., application/pdf}, pages = {1--14}, title = {〈Articles〉Stock Price Paths in Markets with Short-Sales Constraints Populated by Behavioral Traders}, volume = {10}, year = {2012}, yomi = {マルデワ, グジェゴシュ} }
