Great post and lots of wonderful research.
To me, the fundamentals can be out of confluence for a long time...the technicals rarely are. Sure you can have negative divergence yet that isnt a foolproof indicator anyway.
How often does someone go on tv and say the price doesnt match the fundamentals? Of course, people who say this tend to keep saying it for a while. Sure, eventually the fundamentals might catch up....but then again, they might not.
Picking good assets to buy with strong underlying qualities is important. That said, the market price can languish for a long time even if the fundamentals are terrific.
You hit the nail! None of it is fool proof!. Not just picking good assets but having a strategy whether trading or investing is essential, part of that strategy is an exit plan, can be as simple as a sell stop or a patience play to cost down and out.
Glad you enjoyed it! ... i do very much agree on quality assets!
