Soru 15:

An investor has $1,000 to invest in bonds and stocks of a company. A bond costs $5 and pays $1 coupon annually. The expected one-year yield on this bond is 25%. A stock costs $10 per share and pays $0.8 dividend. The total rate of return expectation for stock B is 50%. For liquidity reasons, investor demands at least $80 of cash from dividends (or coupons) at the end of the year. So as to manage the risk of the portfolio, investor sets an upper and lower limit to the percentage of the funds to be invested in stocks, which are 40% and 20%, respectively. The investor has to decide the optimal amount of shares which makes the total rate of return for the portfolio is maximum. According to the information above, what are the decision variables?

A) Maximize Z = (5 × 0.25)x1 + (10 × 0.50)x2 B) The quantities, x1 for bonds and x2 for stocks C) x1 + 0.8x2 ≥ 80 D) 5x1 + 10x2 ≤ 1000 E) 6x2 – 2x1 ≤ 0 and 8x2 – x1 ≥ 0

Soru 16:

Which step of decision making process includes a good understanding of management assumptions, organizational boundaries and the desired conditions for the problem?

A) Establishing objectives B) Defining decision problem C) Listing alternatives D) Identifying outcomes E) Determining the best alternative
