Investing is the intersection of economics and psychology.

Generally, the greater the stigma or revulsion, the better the bargain.

It's incredibly important to note that when you don't allow failure, you get more failure.

Almost no one will accept responsibility for his or her role in precipitating a crisis: not leveraged speculators, not willfully blind leaders of financial institutions, and certainly not regulators, government officials, ratings agencies or politicians.

My experience is that short sellers do far better analysis than long buyers because they have to. The market is biased upward over time-as the saying goes, stocks are for the long run.

Always look for forced urgent selling.

Investing is the intersection of economics and psychology. The analysis is actually the easy part. The economics, the valuation of the business isn't that hard. The psychology - how much do you buy, do you buy it at this price, do you wait for a lower price, what do you do when it looks like the world might end - those things are harder. Knowing whether you stand there, buy more, or whether something has legitimately gone wrong and you need to sell, those are harder things. That you learn with experience, by having the right psychological makeup.
