RSI, MACD show that there isn't anymore a great energy to continue to pull up DOW toward higher and grater records.
Baring in mind the schedule of the tapering, the end of QE and the high unemployment rate in the US which may have a mechanical effect on DOWI, I thing that we may be at the beginning of the end and on the edge of a reversal trend.
Take a look at this monthly chart over last 15 years. The chart itself is self explanatory and should be easy to understand. Another 6 months and we shall know where is this market headed for coming years and how painful things are going to get in stock market....
