It is true that many things are manufacured overseas and/or on low parofit margins distribution channels but 'supplies' still need to be moved from place to place.
I think that the DJTA needs to confirm the trend of the other indices in order to keep any upward movement 'valid'. It certainly doesn't look like it at the moment.
Some of the DJTA components have decent global exposure and they report that demand is not as good as the equity markets want them to be.
For some reason the majority of investors do the same mistakes they did in June and July and want to ignore all the bad news in the pipeline.
