This is what I just heard from Monaco (Jim):
Despite today’s remarkable drop at the open, neither my “short term bottom detector” nor “major bottom detector” models has give even a weak version of a bottom signal since close Sept 29.
(the usual rule being to wait for a “no signal day” before investing, meaning the buy signal was end of day Sept 30)
That doesn’t mean they are right, of course. But they are silent for now.
