RE:RE:RELAX Let's agree to disagree. No one is suggesting you buy weakness. However, what you perceive to be "weakness" when you sell is perceived to be a buying opportunity for another. This is a two sided coin. So is it really weakness to everyone?
By selling when you are down, you have only guaranteed your loss at that point. Sure, you can buy it back lower but unless you have powers of prediction- no one can say what the "low" will be or even guarantee that it will go lower from when you sold.
Ultimately, the point is if you are buying back in (you still believe in that stock) why risk getting off and potentially buying back in at a higher entry point? Why get off in the first place if you still believe in it? Or, why get out when nothing of consequence to affect its long term value has taken place? If you have the resources and still believe in that stock just add to your total on its dips.
Yes, you buy on strength- I don't assume anyone here bought AC on weakness. The difference is I see no "weakness" to sell. This "weakness" that you are shorting/selling is what I call buying opportunities because nothing of consequence has affected AC's long term value. It can go down to 7,6,5 but I am comfortable with that. It will just give the opportunity to DCA my core price down and my profit margin higher.
I do my due diligence and buy and hold until I see my exit point. I am confident of my picks and if anything, I add to my core on any dips. This "amateurish" belief and philosophy seem to work just fine for me (I think Mr.WB did ok too with his pioneering philosophy).
Good luck with yours.
