Problem
An investor bought 200 lots of TLKM shares at a price of IDR 3,410. At the end of the first year the value of the shares is Rp. 4,150, and provides dividends per share of Rp. 100. At the end of the first year period, the investor made another purchase of 100 lots of shares. At the end of the following year (2nd year) TLKM's share price will be IDR 4,300, and it will pay dividends of IDR 100 per share. At the end of the second year, investors again purchased 100 lots of shares. In the following year, at the end of the third year, TLKM's share price was recorded at IDR 4,500 and paid dividends of IDR 100 per share. If the investor sells the stock at the end of year 3, calculate the time weighted return (arithmetic mean and geometric mean), as well as the dollar weighted return.
