Investopedia: Once Again, Rails Suggest Summer Slowdown Isn't That Bad
This summer is starting to feel a lot like last year. Europe seems to be coming apart at the seems, volatility
is tracking up, and investors are on the hunt for proof that the
economy is sliding back toward recession. Like last year, though, the
data from the Class 1 North American railroads just doesn't support a
panic scenario. Yes, business activity is leveling off, but that's what
usually happens in the summer and there doesn't seem to be a compelling
reason to hit the big red button just yet.
