The amount of volatility going on in markets over the past week would certainly make anyone nervous. The US does seem pretty jittery, with an overnight sell-off apparently on the back of the first incidence of Ebola virus detected in the US.
The Dow Jones was down 1.4% overnight but as scary as the Ebola virus is, there are still plenty of other reasons to be nervous about US equities.
This morning, Peter listed a multitude of reasons why US equities could be down so much. They include weak European growth, slower than expected growth in Japan, the geopolitical risks of Russia v Ukraine as well as Iraq and ISIS, US construction was less than expected, QE3 is about to end and October is never a good month for equities anyway.
