Dow Jones Industrial Average trading above 40,000

The Dow Jones Industrial Average briefly traded above 40,000 for the first time but ended the day below that milestone. Investors see it as a psychological boost, but public interest in the market rally seems tepid. The S&P 500 is considered a more relevant benchmark. The move from 30,000 to 40,000 represents a 33.3% gain, taking 873 trading days.
