Listen to this episode of Planet money in 2013: Despite all the celebration, the Dow Jones industrial average has not hit record highs recently. If you adjust for inflation, the highs just aren't as high as they seem. And even if it does hit a real, inflation-adjusted high in the next few weeks, it won't mean much. The Dow is a seriously flawed stock index, and it's certainly not a good way to measure what's going on…
That said, the S&P 500 & Russell 1000 are also at all time highs.

None of these data points mean anything on their own. People that look at a chart a conclude anything at all are not doing enough analysis.
