1. Alpha value
Share’s alpha value is a measure of its abnormal return, which is the amount by which the share’s returns are currently above or below the required return, given the level of systematic risk. If it is positive, investors who don’t hold shares will be tempted to buy them to take advantage of the abnormal return, and investors who do hold shares will want to hold on to them so share price will rise. If it is negative, investors won’t want to buy them, and current holders will want to sell them, so share price will fall.
Current return=expected return+- alpha value
