It is events like these that can change peoples perception in an instant.

I have been raising my cash levels over the last few days and have implemented a short S&P possition as a hedge. I plan to be largely neutral investment wise going into this uncertanty.

He who sells and runs away lives to buy another day.

Nobody cares how great a stock is when they are in panic mode.
There will be great bargains to be had for those who still have cash.
