There was a Dow Theory buy signal in late July when the transports confirmed the new recovery high set by the industrials in January. Since then, however, the indu almost made a new low, but that is because two stocks have suffered "unusual hits" in the indu, AGI after making a two years recovery high in early April, last week lost about 10 bucks, and MRK two weeks before lost an unusual $15, these two "recalibrated" the dow by close to 200 points down. For a little while here, the Dow theory is skewed by these "unusual" events.
