I know where you are going with this,but you are confusing arguments...
Whether you know it or not,you are basically presenting the Value Investor/DCF argument against utilising stops..
And even the Minervini/Canslim crowd would "somewhat" agree with your I got in at 3,it went to 10,Im not selling at 5...
HOWEVER,that argument has ZERO to do with buying at 10 , holding herman and watching the stock trade down to 5....
Its clear you have never really traded.You can not answer simple questions regarding "price action",yet blather on about price channels...
Dum Dum,what more likely,a stock trading down 50%, then retracing 100 or trading down an additional 50%????
And lets not get into compounding
