Mary Johnson recently received a lump sum of $240,000 after selling her old house in upstate New York. Mary would like to invest this amount of money. Her local bank offers Mary an available Gold Client account for her entire $240,000 deposit that guarantees 3.75% return regardless of the future market climate. Mary is also interested in investing her $240,000 in two stock options. The first one is to spend the entire $240,000 to purchase stocks from EliteCure, an upcoming pharmaceutical manufacturer. The projected return for EliteCure stock is 17%, 9%, -2%, -20%, respectively, depending on the future market climate to be excellent, good, poor, or disastrous. The other one is to spend her $240,000 to purchase stocks from AcutePro, a well-established pharmaceutical manufacturer. The projected return for AcutePro stock is 11%, 10%, 7%, -5%, respectively, depending on the future market climate to be excellent, good, poor, or disastrous. The stock industry considers many current economic events and estimates 40% chance to have an excellent future market while the remaining 60% chance to be evenly distributed among the other three (good, poor, or disastrous) possible future markets.
