You are considering buying stock A. If the economy grows rapidly, you may earn 40 percent on the investment, while a declining economy could result in a 30 percent loss. Slow economic growth may generate a return of 4 percent. If the probability is 19 percent for rapid growth, 28 percent for a declining economy, and 53 percent for slow growth, what is the expected return on this investment? Round your answer to one decimal place.
