Avis investments have had disappointing returns. The interest rates on his mutual fund and bond investments have fallen because of a recession and his return on currency trading has declined due to deflation. His investments in the energy sector did not perform as well because of an oil embargo, plus there has been a default on a municipal bond and unexpected declines in the indexes for corporate energy stocks and bonds. In addition, the value of his Clean Energy Co. stocks fell because of a corporate scandal over a product failure. Avi is losing value. What is happening, and what can he do about it? Please explain in detail.
