Alright, imagine you have some Legos (that's your company). Someone wants to take all your Legos and give you only a few dollars for them. But you think the other person should give you more money or tell you why they want your Legos so badly. That's what this Halper Sadeh LLC is doing. They're checking if the people in charge of the company (the board) are being fair to everyone who owns little bits of the company (shareholders). The stock price went up because some people think maybe they will get more money than they expected. But then it dipped a little bit later, like when you drop your candy on the ground and pick it back up. Read from source...
