Shorting?

A few weeks ago when the Greek crisis was happening I got the impression, or some people were saying, that investors were 'shorting' the market.

This is a term for when people sell at a certain amount. I.e. £50 a share. Then the stock market goes down (because a lot have sold) to say £33 a share and they buy their own shares back. So if they shorted 10 shares they would have made £170. (50-33=17, 17*10=170)

But the really smart investors, the investors that have insider dealings, have learnt these tricks. Their not 'shorting' to the novices. Perhaps what they are doing is giving the APPEARANCE of shorting, but what they have actually been doing is GETTING OUT BEFORE THE HERD REALISES WHAT IS GOING ON. They are probably not buying all their shares back, buying a fraction of them back and buying S&P futures. However, the stock market raises again and people assume it's 'shorting'.

If you don't play you can't win, but you can't lose either! Nowhere is this more true than in the markets.
