My rule of market price movements is:
Market moves in such a way so as to maximize transfer of wealth from novices to smart money.
Novices who are talking loudly about shorting the stock will most definitely lose money as well as the novices who are talking of going long. How is this seemingly contradictory scenario possible?
Consider GOOG (Did you mean Good?). Let's say it opened at $130. A, who is long is happy because he thinks stock is worth $300. B, who is short is happy because he knows that the stock will soon go to $10.
Stock price moves up to $150. A is still holding the stock but B really starts sweating. He decides to cover it at a loss of only $20 per share before he really loses his shirt (and pants). He covers at $150.
Now to his dismay GOOG will start moving down - touching $130 and then $110. B's wife will laugh at him. Now it is turn of A to get worried. Seems like GOOG is going down big time. He will sell his stock at $110 before it reaches $10 or lower. He is happy with loss of only $20 per share.
Now both A and B have no positions in GOOG. They will watch it go randomly up and down and to $10 and $300 sometime in future. But A and B have lost money and can just watch together GOOG having its own way.
Moral: Long or short, many new investors who are bragging about their positions would likely lose money.
