Consider the following table: Scenario Probability Stock Fund Rate of Return Bond FundRate of Return
Severe recession 0.10 −40% −13%
Mild recession 0.20. −20% 19%
Normal growth 0.40. 25% 12%
Boom 0.30 30% −9%

Calculate the value of the covariance between the stock and bond funds. (Negative value should be indicated by a minus sign. Do not round intermediate calculations. Round your answer to 2 decimal places.)
