Very typical response as there is NO VAULT in PRICE: Clearly it is NOT OBVIOUS based on mere stock prices. Few if any look at AH trading for it. And with the advent of High Frequency trading unless you have POWERFUL countervening players on the other side of the shorts those OLD WAYS of seeing it do not work IMHO. On the otherhand it is very easy for one to recognize a short covering with a VAULT in prices which is obvious in ABSENTIA.
Very hard to near impossible in this, as it all relates primarily to AH trades: VERY STEALTHY!
Perhaps you know this but most I bet do NOT: For a Goldman Sachs where the number one expense is Personnel. The next highest and not too far off is spending in Information and Technology where the head of it is a KEY Partner with a large expanding budget. For the 1st time in Goldman's history there are lots of personnel layoffs as they are dramatically reducing costs while their IT spending is UP! SAME FOR HEDGE FUNDS! Why do you think Goldman Sachs went to court against one of their former employees who was a software programmer earning $2 mln salary who left and went to IIRC Citadel
Will sign off as I need to attend to developing news as I have expanded my sources to monitor.
