Nassim Taleb on Antifragility

Nassim Taleb on Antifragility, interview at EconTalk (Hat tip: Nancy Miller).

Key early point from Russ Robert's chat w/ Taleb on fragility vs. "antifragility": 
"...Art [Devany] gave me a lot of ideas and suddenly everything flashed together, when I made the distinction between two types of systems, the organic and the non-organic.
The organic has the property that the difference between the living and the dead, the living and the non-living; the living, between living and a machine for example, requires stressors. That's how the complex systems communicate with their environment. You need a stressor. As with the bones, with your muscles, a lot of things. And usually overcompensate for the stressors--there is a mechanism in biology called hormesis. This table I have in front of me will never get better if I bang on it. Use it and lose it.

On the other hand, the human body gets better if it is exposed to the right amount of stressors. Of course, you have to define the stressor and the quantity of stress. But then that makes a difference between two worlds--the organic and the engineered. 

And now, if you can apply that to economic life--is economic life in the first or second category? If it's in the first category then we should have bailouts, top-down engineers, everything. If it's in the second category then sorry, you know, it doesn't work that way..." 

Enjoy the discussion, hope it stirs some reflection.

Lessons from Hedge Fund Market Wizards: Scott Ramsey

Today we continue our series, "Lessons from Hedge Fund Market Wizards" , with a look at Jack Schwager's interview with Scott Ramsey of Denali Asset Management.  Ramsey, a futures trader and CTA who works on the island of St. Croix, spoke to Schwager about his first foray into the markets, his evolution as a trader, and the process he stands by to protect and grow his clients' money. 1) . Ramsey started trading in college. He was roped into the OTC metals market via a broker's ad in the Wall St. Journal. The broker charged customers a flat fee to buy and sell as much as they wanted in a particular market for six month. At the time, Scott was a novice and didn't know about futures, so he traded metals in this fashion through the inflationary run-up of the late 1970s. 2) . Scott had to rethink his trading strategy after he bought silver at $50 an oz., only to watch it collapse to $26 following a long string of limit-down days. He sold as soon as the market...
