Risk and return: an introduction

Every investment has risks. Below are definitions of the types of risks.


 * Credit Risk--the risk of default. Holders of bonds face this risk.


 * Inflation Risk--the risk that one's investment will not keep pace with inflation. This risk can be mitigated by investing in inflation protected Treasury bonds or other assets thought to rise with inflation.


 * Interest Rate Risk--the risk associated with changes in asset price due to changes in interest rate. Bonds and bond funds face this type of risk. As interest rates rise, prices on existing bonds decline and vice versa.


 * Longevity Risk--the risk you will outlive your money.


 * Management Risk--the risk that fund or portfolio managers will under-perform benchmarks due to their management decisions or style. Active funds face this risk. Investors can avoid this risk by selecting index funds.


 * Market Risk--the systematic risk faced by all equity investors due to market volatility. This risk can not be diversified away.


 * Under-performance Risk--the risk your portfolio will not provide sufficient returns to meet your goal(s). Stuffing your cash under your mattress is associated with this type of risk.
