A Bad Teacher

The World’s Worst Teacher

The market often rewards bad behavior. You exit a stock because your stop is hit. You are okay with this because you followed your plan. The market then immediately reverses. You begin to think, “If only I stayed with the position.” The next time the market goes against you, you decide you are not going to get tricked again. This time though, the market does not reverse and what started out as a small manageable loss is now huge.

The market will give you loss after loss forcing you to abandon a methodology right before it takes off without you. On the flip side, the market will lull you into a false sense of confidence. You trade larger and larger, taking on excessive risk. You print money until your risks become so excessive that one or two bad trades wipe you out.

Learn from the market, but realize that sometimes it can be a lousy instructor.

6 ways to think about risk

1  Risk is not the same as volatility. Assets can be volatile on the upside as well as the downside. Risk should instead be viewed as the permanent loss of purchasing power.

2 A risk should not be evaluated based its frequency. Some risks only have to happen once to be catastrophic.

3 Sophistication and knowledge are not a form of or substitute for risk management.

4 Although following the crowd may feel comfortable, risks are just as catastrophic whether you suffer with company or suffer alone.

5 Bullish consensus manufacturers the greatest risks because nobody is prepared and everyone runs for the exits at the same time. Strong optimistic consensus provides a sense that nothing can go wrong. This is why the greatest catastrophes seem to come out of the blue.

6 Activity, research and analysis provides a false sense of control over the future. However devastating losses rarely due to a lack of brain power or analytical prowess.

More Research Confirms The Benefits Of Overconfidence

over-confidenceOverconfidence may cause people to invest too much in volatile stocks because such stocks have a greater diversity of beliefs, and so if people dismiss the objectively bad odds of beating the market, such people will be drawn to stocks where they are in the extremum, and highly volatile stocks have the most biased extremums.  One might think these people are irrational, but in the big picture people with this bias actually have a huge advantage, why Danny Kahneman said it’s the bias he most wants his children to have.
Two economists at Washington State University looked at twitter accounts for sports prognosticators and found that confidence was much more important than accuracy in generating followers. Their sad conclusion: Pundits have a false sense of confidence because that’s what the public, seeking to avoid the stress of uncertainty, craves. In other words, to be popular (read: successful), you need to be unwarrantedly confident. This takes either an amoral cognitive dissonance or ignorance. (more…)
