As of the end of July 2020, an investor with 1 million TL and an investment plan of 6 months has two options. Its purpose is to maximize the combined return on investment. What investment would you recommend him to make?

a. The first of these is to purchase 9-month treasury bills with a maturity of 30.04.2021, issued on 01.08.2020, on 01.08.2020 with an annual return rate of 12%. The investor expects that the interest rates will decrease to 8% at the end of January. Therefore, he will sell the bonds 6 months later (on 31.01.2020).

b. The second option is to buy the common stock of Ford Otosan company. The value of the bills is 25 TL as of the end of July and is expected to be 30 TL at the end of January.
