What about the investor who decides to put 75% of a portfolio in automobile stocks or technology stocks? This investor is taking a risk over and beyond the risk of being in the stock market, because the market as a whole might go up a lot more, or go down a lot less, that these specific choices.
【正确答案】：译文：当投资者决定把投资组合中的75%投入汽车股和科技股，情形又会是怎样呢？该投资者正冒着风险并且其风险超越了投资于股票市场，因为，相比于这些特定的股份而言，股票市场作为一个整体会涨得多，跌得少。
