they work for themselves, brokers and banks and hedge funds. they don't work for investors. they always want investors to sell at a low in order to take profit. when the stock price is lower, their messageboard messages increase. so you can always tell what is happening with the stock when the price is low.
shortsellers are in control of price, until they aren't. they always lose sight of price because they establish an artificial price with their volume. their trading is like a pendulum that always swings low too far and they have to retrace. i enjoy the fact that some shortsellers lose $ because they shorted at the low.
all their messageboard posts are aimed at the investor to get the investors to do something in the shortseller's interest. they do not post in the investor's interest. this stock is a buy and hold for me.
