In the asset management industry, there have traditionally been two types of investment strategies: passive and active. The passive approach includes investment in indices that track specific benchmarks, say, the S&P 500 for the United States or an index of advanced economies or emerging-market equities.
在资产管理行业中，有两种传统投资战略：消极投资和积极投资。消极投资包括指数投资，追踪比如美国标准普尔500这样的具体的基准指数或者囊括发达经济体或新兴经济体股票的指数。本质上你买的是市场指数。
