Another day of flirting with a record high on Wall Street, and yet again, the Dow Jones closed just short of the all time high close of 11,722. That benchmark was set in January of 2000. The Dow was created more than 100 years ago to measure the performance of the stock market. Out of the thousands of public U.S. companies, the Dow tracks just 30 well established ones. So what does its increase mean for your bottom line and what's causing the spike? Investment Experts say lower interest rates and lower fuel prices. The Dow closed under the all time record at 11,679.
