Re: So how long before ...
" the price of oil slumped today"
stocks in general slumped. it's a good time to buy. If I had $ to invest in pound-sterling I'd do it. Expect fluctuations for a week, then "about like it was". Just my 'from across the pond' opinion.
When a small fraction rage-sells, another fraction panics, and you see "that". It'll adjust back.
