I don't believe anyone that says "I can't influence the stock". I don't care what side of the fense you are on.
Who the hell are all these other investors that do influence it? The MM's? The Company? Yes, but ultimately they are controlled by the actions of investors just as much. Gimme a break with that already.
Individual actions make a difference! Even if it is only for a brief moment, it makes a difference. Action/REaction. Nothing escapes that simple law, especially the stock market here in Penny Land where the fastest growing sector of investors are...online! Volitility is an understatement.
Go read a quantum physics for dummies type book. Helped me years ago.
