| Summary: | The purpose of this paper is to compare two different portfolio strategies consisting of insider transactions and stock recommendations and examine whether they posses any information advantage. The portfolios are balanced once every three-, six- and twelve- months in the period of 2007-2009. Our results show a pattern for these investment strategies. The portfolio consisting of insider transactions generates a positive return in equity in a negative market environment and the opposite reaction in a positive environment. The result for the portfolio consisting of stock recommendations show a positive return of equity in positive environment and the opposite effect in negative environment. The pattern that has been observed can be classified as an anomaly. Therefore, we conclude that the market cannot be classified as efficient in a short term perspective. This anomaly is short-lived which indicates that the market is efficient in a long term perspective. |
