What metric tracks the average share price fluctuations of 30 prominent U.S. industrial firms as a percentage?
Show answer Hide answer
Answer: C. Dow Jones Index
Explanation
The Dow Jones Industrial Average specifically tracks thirty major publicly traded U.S. companies. It serves as a prominent benchmark reflecting the general health of the American industrial economy. Price-weighted calculations determine the daily percentage fluctuations of this select group of firms. Established in the late nineteenth century, it is one of the oldest stock market indexes. The index includes blue-chip corporations representing various sectors except transport and utilities. Price weighting means stocks with higher nominal share prices exert more influence on the index.
Investors monitor the index daily to gauge broader market sentiment and economic trends. Financial media frequently cite the Dow as shorthand for the performance of the U.S. stock market. Changes in the index reflect investor confidence in large industrial and corporate enterprises. The Nikkei Index tracks prominent stock prices on the Tokyo Stock Exchange in Japan. The NASDAQ is a technology-heavy stock market index featuring thousands of domestic and international firms. The Major Market Index tracks a different basket of twenty blue-chip stocks with distinct weighting.
