Suppose this morning SPB Ltd., a solar panel and battery manufacturing company, paid a dividend of $3 per share. At 10 a.m. SPB announced its latest earnings results (which were unexpectedly good) and management seems very happy. One year ago, SPB paid for and implemented the Stealth Disposal (SD) project for handling its toxic waste. Only SPB's management is aware of the SD project. The project has reduced SPB's expenses related to toxic waste disposal, but there is a 25% chance of toxic contamination of the drinking water for the nearest city. SPB management has no intention of publicly disclosing that the SD project exists. Following this morning's 10 a.m. quarterly earnings announcement, SPB's earnings growth prospects look very good based upon substantial cost savings (although investors don't know it, these cost saving are due to the SD project). SPB's earnings announcement has caused investors to reassess SPB's dividend growth with the new expectation that dividends will grow by 0.4% each quarter. Prior to the announcement, dividends were expected to grow by 0.3% each quarter. In addition, given investors' perceived risk of SPB, the equity cost of capital for SPB is 11% (effective annual rate). Complete parts a through f below. a. Assume the market is semi strong-form efficient. What was the price of SPB's stock at 9:30 a.m.? b. Continue to assume the market is semi strong-form efficient. What was the price of SPB's stock at 10:30 a.m.? c. By what percent did SPB's stock price change between 9:30 and 10:30 a.m.? Is this consistent with the efficient markets hypothesis?
