Akasuki works for an investment firm in Japan and is managing two portfolios for two different clients: the Nakamura family and the Saito family. Both portfolios had the same holding period return last year. Most of the returns for the Nakamuras’s portfolio came from dividends, while most of the returns for the Saitos’s portfolio came from capital gains. Which of these families is likely to be a working couple and which one is a retired couple? Why?
