S&P 500: The abbreviation for the Standard & Poor's 500, an index of the prices of 500 corporate stocks traded on the New York Stock Exchange. It includes an assortment of stocks for industrial, transportation, and utility companies. It also includes a larger number of stocks than the comparable Dow Jones composite index, which means it's often considered a better measure of the overall performance of the stock market. Less commonly publicized are separate Standard & Poor's indexes for industrial, transportation, utility, and financial stocks.

The family of short-run cost curves consisting of average total cost, average variable cost, and marginal cost, all of which have U-shapes. Each is U-shaped because it begins with relatively high but falling cost for small quantities of output, reaches a minimum value, then has rising cost at large quantities of output. Although the average fixed cost curve is not U-shaped, it is occasionally included with the other three just for sake of completeness.
