The DJIA is not as good a metric compared to say, S&P500. It considers a 1$ move in any of the constituents in the same manner, so a stock worth 200$ moving up by 1$ is given the same importance in terms of points change in the index value as a stock worth 2$ moving up by 1$ (whereas fundamentally speaking, the second movement is far more interesting than the first).
