Several months ago GS had HFC on its preferred list + WNR a buy, they then reversed it. Now several months later, they reversed it again.
Jana sold 25% of its MPC at ~42/share + pocketed 44MM + have options to buy another ~850K shares at 27.50/share. Icahn the perennial raider who has pocketed a ton on CVI, up 23%, has told the BOD to sell the company. These hedge funds need massive regulation as they manipulate the markets to their own benefit as the retail investor can only hope they are in the stock the raiders have positions. Right now they have targeted the refiner sector + they will put a lot of pressure on these firms to return shareholder value, ie, more money in their pocket and who cares what happens to the company next week as long as they hit their profits this week. If they leave the company in shambles they could care less as their wallets bulge.
Sometimes it a good thing as it pushes poor BOD's into making decisions they would never make on their own that may benefit the company but far too often its to the detriment of the company.
