agree antibody.

You should always be prepared to revise your decision, but you must do this without fear.

If your analysis is coloured by fear or hubris, quite obviously you aren't going to be objective.

So your analysis gets coloured by emotion. Mastering this dynamic is one of the most difficult aspects of successful investing IMO.

Confirmation bias is another aspect of emotion driven decisionmaking. But it is overemphasised, often by traders.

If you are thorough in your research, and cool with your analysis it's not a factor.

DYOR is only part of the solution. Mastering emotions is the big X factor which often tips a promising portfolio into a coulda shoulda hindsight category.

Holding your nerve is sometimes the most difficult thing to do, and the wisest thing to do. When under pressure, the temptation is to take action, and the obvious action is selling.

This is one way of silencing the anxiety, the constant drip drip drip of negative comments, the anxiety of a share price under pressure from shorters etc etc.

But silencing the voices of anxiety is surely a short term solution to what is not really a LT problem at all, if it is carefully and systematically assessed.

Properly characterising the problem, and the perceived problem? This ability IMO are what determines success.

No doubt we will get opinions from other sources now, but this is my view after being mentored by a former serious investor and he knew a thing or two about holding your nerve. He also knew a thing or two about the inside of the broking and corporate worlds.
