Explain in brief about the Default Risk
It's that portion of an investment's total risk which results from changes in the financial integrity of the investment. For instance, when a company which issues securities moves either further away from bankruptcy or closer to it, these changes in firm's financial integrity would be reflected in the market price of its securities. Variability of return that investors experience, as a result of changes in the credit worthiness of a firm in which they invested, is their default risk.
