DislikedI do doubt anyone really traded that news. No one important anyway. Purely from respect and worry for alot of companies. As it was the world trade centre...Ignored
I know for a fact that a number of banks now have off sight 'bunkers' where they can operate from if such an event were to happen again.
When we are talking about massive financial institutions with billions of dollars worth of assets, the option to sit back and not trade 'out of respect' is sadly not really an option. There is too much to lose (or gain for that matter).
