There was a rumor of a terror alert that affected U.S. stocks and raised some concern in Brazilian markets as well.

I think that (the terror alert rumor) was most of this ... it's already rallying back.

A this time there are no plans to adjust the terror alert level.

People are a bit concerned with higher Treasury yields and the possibility that U.S. interest rates will continue to rise.

The market has a very consistent forecast for a decline in interest rates and everyone is betting strongly on that. The prevailing expectation is that this may be the last chance to get into the market before rates fall, so we may see a large inflow of dollars in the short-term.

Buy the rumor, sell the fact.
