That at least is the conclusion reached by a frightening chart that has been making the rounds on Wall Street. The chart superimposes the marketâ€™s recent performance on top of a plot of its gyrations in 1928 and 1929.
The picture isnâ€™t pretty. And itâ€™s not as easy as you might think to wriggle out from underneath the bearish significance of this chart.
I should know, because I quoted a number of this chartâ€™s skeptics in a column I wrote in early December. Yet the market over the last two months has continued to more or less closely follow the 1928-29 pattern outlined in that two-months-ago chart. If this correlation continues, the market faces a particularly rough period later this month and in early March.

One of the biggest objections I heard two months ago was that the chart is a shameless exercise in after-the-fact retrofitting of the recent data to some past price pattern. But that objection has lost much of its force. The chart was first publicized in late November of last year, and the correlation since then certainly appears to be just as close as it was before.
To be sure, as McClellan acknowledged: â€œEvery pattern analog I have ever studied breaks correlation eventually, and often at the point when I am most counting on it to continue working. So there is no guarantee that the market has to continue following through with every step of the 1929 pattern. But between now and May 2014, there is plenty of reason for caution.â€
