Ok, lets go with that. So if some folks are repeatedly shorting and covering, shorting again and covering again. If they are repeatedly doing it at the most oppurtunate moments... That would just be "trading" right? how is this different from actively buying/selling (instead of shorting/covering)... What I thought you are making a claim is that shorts are suppressing the stock price. I am having a hard time connecting the dots to that.
Yesterday's volume was 13mil shares. Could shorts really "control" the price with that kind of volume?
This was addressed so many times by Kurt and others. When trading, either selling or buying you do not move the price because it works against trader. Engaging in either price support or suppression is totally different. In case of shorting you want to time large trades with the downward ticks, greatly multiplying the effect, potentially triggering cascade of stop loss orders or panic selling because abrupt drop typically is associated with some kind of bad news. So when people see such a drop it unnerves, sometimes enough to panic sell. The key is concentrated in time selling. This is well known technique, and I am surprised that you are unaware. I actually saw a very good description associated with the SEC rule which limits short selling activities under some circumstances - you can just surmise how this works straight from the SEC wording about the prohibition. I don't have time to dig it out now, but will later. May be somebody can help if has time now...
