Discuss the following two scenarios.
Scenario 1: Is the following statement true or false? Explain.
When the 56-year-old founder of Gulf & Western, Inc. died of a heart attack, the stock price immediately jumped from $18.00 a share to $20.25, a 12.5% increase. This is evidence of market inefficiency because an efficient stock market would have anticipated his death and adjusted the price beforehand. Assume that no other information is received and the stock market as a whole does not move. Is the above statement true or false? Explain.
Scenario 2: Is the following statement true or false? Explain.
On January 10, 1985, the following announcement was made: "Early today the Justice Department reached a decision in the Universal Product Care (UPC) case.
