NEW YORK (AP) – The Dow closed above 14,000 on Friday for the first time in more than 5 years.

It was just a number on a board, but it was enough to raise the hopes of some investors and cause others concern about an overheated market. And it brought reminders of a different era, back before the financial crisis rocked the world economy.

The Dow Jones industrial average, a stock market index that is traditionally considered a benchmark for how the entire market is faring, had been rising fairly steadily for about a month.
