Expecting a quite volatile Open and an especially (25%) higher volatility for October.
Please check the US Federal Reserve Repo Rate. The whole last week the Fed had to provide liquidity to the large Financial Institution as they needed to borrow money.
This had also happened at the immediate beginning of 2008. IF they are in good shape why do they "All" have to go to the Fed Overnight Window .... every day last week. Come to wonder - sorry I don't believe the large Banks are in good shape.
