Before a attack is launched, there were a lot of preparations made by shorts.

True. There are a couple of warning signs that I know about now.

1) Look at the DEER chart from nov '10 until April '11
That's a very unusual chart and the stock wasn't able to move up because the shorts were loading up.

2) On one instance there was a massive increase in volume in the number of puts traded. And they were bought at a premium. That was two days ahead of the attack. That by itself caused the stock to drop 7% temporarily.

3) People will be asked by their broker to lend out their shares. Because there was is a shortage on the number of shares available to short.
