RE:Let's be rationalGobomber,
Would you agree with me that whoever sold shares in the actual context contributed to this mess (up to certain extent given the importance of the sale), regardless of the reason why they did?
The guy who shorted the stock to make a profit is not very different from the one who sold to generate a tax loss. They did the same action with the same consequences but for different motives. Everything then is in the magnitude of the transaction?
Little volume is OK?
Large volume is not?
There is a smart guy centuries ago who said:"Don't throw the first stone".
