Comment: The context of this post though,

is that the last six months prove ship overbuilding had nothing to do with the '08 plunge. To make such an assertion, the index would have to have gone down the last six months (which still would not prove that assertion anyway).
For the record, I agree the six months is near meaningless. The best that can be said is we've been flatlining since the '08 low, which predicts neither a coming crash nor a re-bound in global manufacturing.
