A futures contract essentially gives the owner of the contract the ability to buy a specific amount of a good at a given price at a point in the future. In a 1984 paper titled Orange Juice and the Weather, economist Richard Roll showed that the price of frozen orange juice futures could be used to predict errors in weather forecasts for Florida made by the National Weather Service. That is, there were times when the price of orange juice futures did a better job of predicting the temperatures in Florida than did the National Weather Service!Given this information, which of the following would the efficient markets hypothesis suggest was occurring?a. Investors in orange juice futures were using publicly available information that scientists at the National Weather Service were not using. b. Scientists at the National Weather Service had private information that they were not making available to the public when issuing weather forecasts. c. The futures market was on an extended lucky streak. d. Frozen orange juice futures must have been a riskier investment than the stock market since you had to bet against scientific experts to do well.
