当某一美国投资者发现他持有的国内股票型基金近几年业绩表现超越同类基金时,他的基金很可能投资了国外股票。据晨星统计,美国采用分散投资策略的国内股票型基金,有大约10%的资产配置在国外股票上。最近5年采取分散投资策略的国外基金的年化回报率在17%～33%,而同类型的国内基金表现最好的年均回报率也不超过15%。 When a U.S. investor finds that the domestic equity funds he holds have outperformed counterparts in recent years, his fund is likely to invest in foreign stocks. According to Morningstar statistics, the United States uses a diversified investment strategy of domestic equity funds, about 10% of the assets allocated to foreign stocks. The foreign funds that have adopted diversified investment strategies in the past five years have an annualized return of 17% to 33%, while the best-performing domestic funds of their kind do not exceed 15% annually.
