Probably a liquidity problem. There just ain't any buyers in this market, a few left are playing stock indexes. Those not in the index gets forgotten. If you have someone selling 10k shares, stock tanks.
Here we go with the betting like the court ruling and we lost.
Yes, I understand the thin volume influence, but I sure would like to see a positive volume. Could some of the big holder be leeking their shares bit by bit? Price drops with heavier than usual volume does not bode well. It is always a possiblity that Constellation is bowing out, et al piecemeal.
