I have trouble understanding the reason of your quote. If we consider the market uncertain or bearish, are you quoting them as an exemple to follow ? Or since they are being greedy, are you quoting them to point out what your readers shouldnt do ?
Just observing human nature. These guys seem to be using a quote from Warren Buffet to justify an action, but violate their own rule by what they say. The human capacity for self-deception is amazing.
Which of the two would you rather be?
1. I make decisions based on my untested, fickle emotions.
2. I make decisions based upon research and facts.
I think most would either desire or claim to be number 2, but when money is on the line, we tend to revert to #1.
