Economic and market data that represent an overall trend. The Dow Jones Industrial Average is an example of a stock market barometer.

Barometer Stock

A stock in a well-known or highly-regarded company in a given sector. The performance of a barometer stock is considered to be an indicator of the performance of its particular sector or industry. The term "barometer stock" is chiefly British; in the U.S., the primary term is bellwether stock.


An indicator of fluctuations. For example, the S&P 500 is a barometer for stock market movements. Likewise, long-term interest rates are a barometer of inflationary expectations.
