I’ve learnt to accept that until something major happens, the shorts are firmly in control. Seems like a piece of cake for them. I wonder if they get up in the morning and say: “Let’s cap today at X or take it down a few points to Y”.
Intruiging, but really not important in the realm of things.
What I really fail to understand.... the short % seems to be creeping up. Who in their right mind would short at these levels??!!
