Anyone could have seen this coming. It was grossly overvalued as I have written before and as the SA today pointed out. Also DOM has done this in the past. A couple of years ago it ran up to almost 20 before plunging back down to 10. The runup past $10 made no sense at all and it was clear it would reverse. Each time it does this I make some money via options.
If you thought yesterday was bad, look at the pre-market today and look at the Seeking Alpha article. This security is going down 75% because it was way overvalued. I do not know why folks do not understand these oil trusts. They are a wasting asset that will go zero.
