As an attachment, stock price manipulation is also allowed. This is done sometimes in an effort to gain control of the vote of the company so that a better deal price can be negotiated and where shareholder resistance can be over powered and shareholders brought into a submissive stance where they accept an offer.
One of the main wrenches into the wheel, if you will with us, is that we were and are, too well informed on the value of not only the Tesoro, but all the Peruvian properties. By being this informed, it is/was known that the majority of shareholders would not accept an insulting offer less than $100,s per share. It is because of the above, that the stock price was hit, to scare out shareholders, grab their shares, which would break the controlling interest shareholders had in the company. Also, this is why the information for the property released was so scarcely clad, as to not reveal anymore information that would validate the prosperity of the Tesoro, and cause shareholders to buy more shares.
