You probably have never traded. So what. 140 pips is nothing. Dow Jones has fallen 7000$ - thats 70000 pips in a couple of months when the crysis began. Some people got billionaires (literally) off short positions.
It is ridiculously easy to hack the Twitter account of a major news agency(probably only requires a trojan exploiting a unpatched IE), compared to predict the series of events before the subprime crisis and be in a position to go against the trend with enough funds, the input-ouptput ratio is just different.
