指数的中文解释

各种数值的综合，用于衡量市场或经济的变化。以股价指数为例,指数反映的是一组特定证券的价值,开始时通常会选择以100(或1,000)为基数,反映某一时点该组证券的价值,指数随后的变动反映了该组证券(即成份股)总价值的变化.

Index的英文解释

A composite of values designed to measure change in a market or an economy. Indices are usually created by measuring the value of a number of securities, or an economic indicator, at a certain date and letting that value be represented by 100. Subsequent changes in the index can be easily perceived in comparison with that 100 base number
