Even better than 11/9, on 9/22 the pull back was almost 10%. (Could have bought for $42.88.)
I've been tracking CAM for intra-day lows over previous close, and charting results. It looks like ~~9%/10% is the 'sweet' pull back threshold. Buying on those days almost always ensures being right back into the black will come within ten trading days, often sooner. Technique very basic and simple, to be sure, but works so far.
(Have to stay heads up and pull the plug when CAM and/or the whole market environment is in a clear down correction. Q4 2008 was a significant recent example of one of those times. I disremember what the exact reason was for the panic, unless maybe it was His Royal Massiahness' coming coronation?)
