Monty Frost's tax deferred retirement account is invested entirely in equity securities. Because that international portion of his portfolio has performed poorly in the past, he has reduced his international equity exposure to 2%. Frost's investment adviser has recommended an increased international equity exposure. Frost responds with the following comments. a. Based on the past poor performance, I want to sell all my remaining international equity securities once their market prices rise to equal their original cost. b. Most diversified international portfolios have had disappointing results over the past five years. During that time, however, the market in country XYZ has outperformed all other markets, even our own. If I do increase my international equity exposure, I would prefer that the entire exposure consist of securities from country XYZ. c. International investments are inherently riskier. Therefore, I prefer to purchase any international equity securities in my "speculative account, my best chance at becoming rich. I do not want them in my retirement account, which has to protect me from poverty in my old age
