Did you look at those particular three hours of DCTH last Thursday? Did you wonder how I managed to get in and out within exactly those three hours, and clear a profit? What did I know, that you didn't?
Whatever struggles that company is having is immaterial to my having known exactly when to get in and out. To clue you in, I was tipped off by a fellow stock trader, who simply said that it was heating up for no reason that he could see.
I looked, and the reason was a proxy battle for control of a company vote, over a "reverse stock-split" coming up very soon. I guessed that the battle would be short lived, because the two sides already had almost enough proxies to prevail. I bet that they were each just picking up a few million extra shares, just to get over the top.
I shared that insight with my fellow traders, and many of them jumped in and out, just as I did.
You looked at DCTH, and now I have given you a useful clue.
