A bond with face value Rs. 100, maturity of 3 years and a coupon rate of 10%is issued. The market interest rate at the time of purchase is 8%, and falling. The investment in this scenario promises to be attractive for the investor as it offers greater returns than the present market rate. The market price of this bond will therefore be higher than the face value. Now, if the market rate increases to 10% in the second year of the investment, the bond no longer remains attractive and the market price drops down to Rs. 90.

The average investor in Congress underperformed the market by 2-3 annually during this period a finding that contrasts with earlier research showing uncanny timing in Congressional trades during the 1990s. Members invested disproportionately in local companies and campaign contributors and these political investments outperformed the rest of their portfolios local investments beat the market by 4 annually . Our findings suggest that informational advantages enjoyed by Congressmen as investors arise primarily from their relationships with local companies and that widespread concerns about corrupt and self-serving investing behavior in Congress have been misplaced.

Introduction Do members of Congress enrich themselves by picking stocks based on privileged political information There is substantial anecdotal evidence that they do. Senator Dick Durbin for example reportedly sold stocks in September of 2008 just after a closed-door meeting in which .
