Generally traders invest in a individual transport name such as UPS, FDX, CP, UNP, KSU, etc. or the popular iShares transport ETF $IYT.
I found this chart, however of thinly-traded Spyder ETF $XTN quite interesting however and thought I would share it with you.
With the stocks and ETF above, you have a lot of high frequency trading going on so spikes in volume are few and far between BUT with thinly traded XTN, there has been an enormous amount of volume since October. I mean HUGE compared to the last 5-6 years...........and it makes me wonder. Is the top "in" in rails?
HFT trading in names may have masked any selling but seeing so much flow "out" of this ETF raised my eyebrow.
On a daily view it certainly looks like it could be forming a bearish descending triangle as many feel, if transports go, so goes the market. Just sayin' - Europe is weak, China has slowed......
Full disclosure I am short CP
