The question begs
Will BRexit calm down and get better or go away, or will it worsen and turn into Dexit, SWexit, Grexit etc.
The unfortunate thing for CXR is that at best, BRexit will linger on for some time and hence CXR may remain weak for some time. Safer to let this ship first turn he corner and consolidate rather than trying to catch the bottom here.
This is likely the SHORTS modus operandi at present here.
