RE:RE:RE:RE:RE:RE:RE:Greager needs to GO. Get a Canadian CEOOr it could be Loss Aversion Bias. The theory is that people feel the pain of a loss much more than the joy of a gain. Applying this to stock investments, it's very difficult for most investors to admit they made a mistake investing in a company, crystalize their loss on the investment, and move on. Thus, people resort to rationalization tactics such as "it's only a paper loss - it's not a real loss unless you sell". Taken to the max, a person could hold on to a dog, buy more, average down, etc. and keep all shares for 20 or more years without selling shares and still claim it's not an actual loss because they haven't sold yet and a don't want to miss a big turnaround in the share price that may occur any day / week / month now to "at least break even".
Of course there are instances where a good quality company hits a rough patch or makes a bad decision managment recognizes and are correcting in an effective manner that the investor has genuine confidence in, but this too may be influenced by another form of bias: Confirmation Bias, in which an investor seeks out / favours information that confirms their existing opinions on the company and its future while dismissing facts or data that refute the bullish arguments instead of taking an objective look at the pros and cons of the company and selling their shares if the exercise results in the latter presenting the stronger case.
