Might be a good time to mention Kahneman and Tversky's Prospect theory and how it relates to investor behavior in situations of losses or gains.
Briefly, if one perceives himself to be in a loss situation he will behave as a loss seeker- ie. not take a possibly smaller but definite loss but rather wait for a bounce back. The loss need not be an accounting loss, just perceived as a loss which usually depends on the anchor-ie. what former or attained price has become accepted as normal by the investor.
OTOH, in perceived gain situations there is a tendency to sell and nail down the gain.
I think this is a very powerful behavioral tendency that successful investors must find some way to control or adapt to.

Excellent point Ha. While intellectually I am aware of the theory, emotionally it is tough to overcome it. In my taxable account I am disciplined about selling loser before the end of the year and/or they turn into long term losses. But in my IRA, not very good.
For example my BIL was very high on biotech cancer drug. He is a smart guy who never makes recommendations (now we know why). I bought two small positions one in my taxable at $9 the other in my IRA at $11, by the end of the year the stock was down to $5 (a price point above where my BIL had bought most of his stock). I dutifully sold my stock in the taxable account, and while doing so I asked myself why do you own this company at all. I didn't really have a good answer. But I hated to lock in 50%+ loss.
I stopped asking myself that question in the next 3 years the stock has steadily decline from $5 to $.08 LOL. At this point I hate to pay the $9 commissions for a $45 holding... Of course sometimes you get lucky and one of these dead birds, rises Phoenix-like and soars very high.
