This may work for you but not for me. I seem to get the swings wrong. frustration wAs setting in with avz swinging in the 2 to 4’s and a valued poster here sold in the 4’s I believe and entered much higher again. I’d been through the pls swings from the 50’s to 60’s and so many made from this except me. So I near traded out of avz in the 4’s. Thankful that I didn’t. It’s always hated the buy back in and get half the shares you sold. One poster said after yours that sell the bad ones on hype. But you only own bad ones by default as they didn’t perform as expected. I try not to own poor performers. I’m getting much better at selecting now.
A point on your Hartleys comment. It was very well posed here that they had completed there selling some months back, how little ng can we use this reasoning.? How do we really know?
