Which of the following statements is FALSE? Credit spread is the yield of a corporate bond less the yield of a US Govt bond of comparable maturity. Credit spreads are a form of compensation to the lender for bearing the borrower's credit risk. That the S\&P 500 has suffered periodic declines by as much as 4050% indicates that stocks have NEGATIVE risk premium over time.

Credit spreads typically widen during recessions as investors become more fearful and require greater compensation for a given level of credit risk
