I'd become increasingly worried if it crossed 0.450 and headed sharply to 0.500. It would become a big problem for the banks if it got up to the similar rate in 2008 of 0.550.
I'm prepared for the market to fall another 10%. I don't think it will because the present situation is very different to 2008. I visited the US in March of this year from West to East Coast and what I saw was an economy bottiming out. I also live in Berlin and although most managers I know are forecasting recessionary growth for the next two quarters here, they don't envisage that the downturn will be that deep or as long.
