Another big week is in the books for Wall Street, and many believe the current rally has gotten long in the tooth with the Dow Jones industrial average passing the 14, 000 mark for the first time since October 2007.
An early milestone of this bull run happened on April 17, 1991: The Dow reached 3, 004.46, passing its July 1990 high and posting its first close above 3, 000.
