As you see from the case of investment A and B, you will know that the risk of losing money from investment B is hedged by the gain in investment A. On the other hand, you can think that the gain in investment A is unluckily reduced by the loss in investment B. It is true that the possible earning from the total investment portfolio can be lower is the risk is hedged. It makes sense as the lower the risk, the lower should be the opportunity and earning.
To illustrate more clearly, we can now assume a case with interest rate swap. Assume that you have borrowed a $60,000 loan from a bank
