Now why on Earth does anybody think that they know what are they doing? :)
There could be thousands of reasons for this + who says, that financial institutions can not make mistakes? Ofcourse they do mistakes and about 50%+ of the time! One starts selling, another one sees that and...
Anyway, in generally, they know nothing more than we do.
investronic, Don't be silliy. Of course institutions have much better tools, dd and analysis accrss. They risk millions of dollar and for sure they pay top dollar to protect their investment. Basically, they decide the stock direction.
