It's well known that this sheet continues to happen on a daily basis. Indeed, many of the incomprehensible upgrades/downgrades are also part of this sheet.
But whoever throws himself into a stock just because he sees it moving MUST be ready to lose is ass there, and shouldn't be given any relief just because someone was painting the tape for him to fall into it.
The true fraud is where accounting is involved, and where upgrades/downgrades are used to manipulate stocks.
For instance, just a few weeks ago UBS upgraded WYNN. WYNN is the "no casino" casino stock. They haven't got any casinos yet (they are building one, and will build two), but cause the owner is a well known Casino Guy (Steve Wynn), the thing trades like it's one of the largest casino operators in the world already.
What sense does it make to upgrade something whose status hasn't changed for months, and that already trades at an incredible valuation, and that has already gone up 2-3X while nothing new happened there?
Of course, that upgrade marked the VERY TOP of that stock.
Same with CORV a few years ago. It was only Buys and Strong Buys. What sense did it make to have Buys and Strong Buys on a company that didn't have ANY REVENUES at the time, and yet was already worth as much as GM?
Even if CORV had somehow grown into the valuation, those buys and strong buys were unwarranted, it was like having those recommendations on a Lotto ticket with a 1/100th the likelihood of a payout of a regular Lotto ticket.
That's where the fraud is.
