A single stock or portfolio of stocks which varies in the market average is defined as abnormal return in the stock market trades. If the stock outperformed the market average then the abnormal return will be positive, and if it underperformed then it will be negative. This abnormal return definition is relevant with financial gains and losses which are measured against the actual index instead of artificial or hypothetical measure.

Other countries are having their own market index according to their national markets for purposes of determining abnormal returns.

The percentage sum of all abnormal returns over a defined period of time is called cumulative abnormal calculation that account for these normal variations. [click to continue…]
