Stock Market Indices
A stock index or stock market index is a method of measuring the value of a section of the stock market. It is computed from the prices of selected stocks (sometimes a weighted average). It is a tool used by investors and financial managers to describe the market, and to compare the return on specific investments.
An index is a mathematical construct, so it may not be invested in directly. But many mutual funds and exchange-traded funds attempt to "track" an index (see index fund), and those funds that do may not be judged against those that do.

If he leaves it to nature to carry out the sentence.

And pay a death tax of fairly polite repentance.”

Greet prees at market maketh dere ware,
And too greet chepe is holden at litel pris.”
