Question 6 3 pts Arthur buys $1,500 worth of stock. Six months later, the value of the stock has risen to $2,000 and Arthur buys another $1,000 worth of stock. After another eight months, Arthur's holdings are worth $2,300 and he sells off $800 of them. Ten months later, Arthur finds that his stock has a value of $1,600. a) Compute the annual time-weighted yield rate of the stock over the two-year period. (Round your answer to two decimal places.) % b) Compute the annual dollar-weighted yield for Arthur over the two-year period. (Round your answer to two decimal places.) % Should the answer in part a) or part b) be larger? Why? Choose one from below, Mor N? M. The dollar-weighted yield should be larger because this proves that withdrawals and deposits were timed well. N The time-weighted vield should be larger Tale UI LE SLOCK UVEI tie two-year penou.
