If there is value and i get in and it goes against me but my premise is still correct ..just my entry was off ...and the market hands me the opportunity to buy something of value, at an even greater discount, well caramba, I’m taking it. Wouldn’t you?
Normally, I wouldn't; no.
For three main reasons ...
First, the "something of value" is relative, and the more its price is discounted when I've bought it, the more it starts to look like potentially "something of less value";
Secondly, the "if" in "if ... my premise is still correct" is becoming bigger and bigger, as the price moves in the opposite direction, and I'm honest enough with myself to acknowledge that;
Thirdly, my decisions are probability functions, and they need re-assessment in the light of subsequent events, and I don't pretend otherwise: I've noticed that some people who do pretend otherwise seem occasionally to make some hugely expensive mistakes, and I'm too risk-averse to want to increase my chances of joining them.
So I take my hat off to people who can achieve that with perpetual success, but I can't, myself (and to be completely honest I don't really aspire to, either - it doesn't seem to me like a particularly good use of my skills, effort and energy).
Just my perspective on this ever-thorny subject.
