I've been following this ETF since lumber prices have been falling from their sky-high prices. Just now, it looks ready for a markdown phase that could get pretty ugly. Though it is currently well below, if it manages to get to around $83-84 dollars, I think that shorting it there would be an incredible opportunity with minimal risk and solid reward potential.
Disclaimer: I think we're at the end of a market cycle and are currently in the process of redistributing before another leg down in what I believe will be called a crash when it is all said and done.
It is finally rallying, but I'm not at the point where I am shorting it just yet. Waiting to see how high it gets next week. As I said before, a short at 84/share should work like a charm
