I watched US financials tank on July 15th and figured it was the low point for most, and this is exactly what's happened - even with the Dow Jones plummeting, most US financials have not dropped to July 15th levels - it's mining and oil especially that's dragging it down, as I predicted would happen on July 16th.
I also predicted October could see the FTSE 100 drop to 4500, and it's almost there already - I'm just hoping that's as far as it goes.
