Today's entry, a year later...

Today's entry:



I've never made money following the crowds. I've always made money going against the masses. If I were to hire someone to manage my money, I'd rather them have a background in crowd psychology and mob theory, instead of degrees in econometrics. People tend to rely too much on numbers on things not necessarily controlled by numbers. It works for designing innovative technology; it does not work for predicting behavioral finance.

In other words, when they win, it's because of their savviness and acumen, and when they lose, it's due to bad luck.

It is analogous to a reknown physicist claiming he will find the next treatment for certain types of cancer, using stem cell research. The interviewer decried his attempts, asking how a physicist could solve a problem that was clearly a medical and a biotech one. He curtly replied that biologists and people who study medicine don't know numbers. Metastasis is a compounding problem, an uncontrollable geometric growth of malignant cells. The drug discovery process itself is a numbers game. He was spot on in his approach.

OTOH, behavioral finance is more behavioral than economic models, and mere numbers. Market participants are human, not drones who predictably turn like electrons.

I've had very long and interesting discussions with some of the brightest minds on and off Wall Street, and many of them think the number-crunchers are deluding themselves into thinking they can outsmart markets. And the road kill of some very smart people only confirms my suspicions. It's like a casino: the players keep playing as long as they win, but as soon as they lose, they get washed out for the next group of gold speculators to arrive.

The key is to manage OPM, as the managers make money no matter what their performance is, and they last as long as they can get away with it (underperformance). The clients underperform the index averages 80% of the time. And the top 10% managers are so good that they can outlast their peers, and make a killing over their life times.

I've reached a stage where my clients and I can't afford to take a hit like the tech bubble, and the recent subprime mortgage crisis. It's about capital preservation, efficient (i.e. low-cost) diversification, risk mitigation, asset optimization (all assets, not just investable liquid assets), and guaranteed floors (the last two are why I win). Lots of people can claim the first 3, but few can deliver the last 2.
