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.

Famous quotes containing the words stock and/or market:
“There exists, between people in love, a kind of capital held by each. This is not just a stock of affects or pleasure, but also the possibility of playing double or quits with the share you hold in the other’s heart.”
—Jean Baudrillard (b. 1929)
“When General Motors has to go to the bathroom ten times a day, the whole country’s ready to let go. You heard of that market crash in ‘29? I predicted that.... I was nursing a director of General Motors. Kidney ailment, they said; nerves, I said. Then I asked myself, “What’s General Motors got to be nervous about?” “Overproduction,” I says. “Collapse.””
—John Michael Hayes (b. 1919)
