Um bom exemplo de como os "shorts" são mais vezes responsáveis pelas subidas vertiginosas das acções do que pelas suas quedas.
"Research In Motion Shows Danger in Shorting"

"Research In Motion (RIMM:Nasdaq - commentary - research) just went from supremely and totally overvalued to ridiculously and ludicrously overvalued. Stay tuned and it can go to completely and utterly overvalued before it goes to outrageously and stupefyingly overvalued.
You see that's why you can't short on valuation. It just doesn't work. Not when there is a huge amount of liquidity in the system and too many hedge funds chasing too few shorts.
What did you need to do to outgame the shorts here? All you needed to do was look at the rising short position on Bloomberg. Before I ever shorted a position, I always hit up the stock plus SI for "short interest." When you see it soar, as you saw for Research In Motion, you know you are going to get your lungs ripped out if anything good happens.
That's fine if you have a second set of lungs.
I don't. "
