Nassim Taleb Bloomberg Quant Finance summary and notes

May 29th 2015 Bloomberg Quant Finance Seminar:
Nassim Taleb Presented ‘The Law of Large Numbers in the Real World’
Takeaways:
– Fat Tails exist can be described by some negative exponent Alpha
– The Tail or Alpha distribution is Normal even though the Price
and Return distributions are not ( Use Pareto or Power Law Distribution for them, 80/20 Rule)
– Minimum sample space needed for convergence to a stable moment: Normal – 30, Pareto – 10^14 (100 Trillion)
– Asked Nassim about what type of historical financial data he used
He responded that I should take a look at his paper. But I suspect it is mostly monte carlo generated data. I didn’t find any specific data sources yet. But he claimed to be able to capture the fat tail
behavior of the SPX, by finding a stable moment in the power law
distribution, K*Alpha* X^ -Alpha
– Julien Guyon (Author: NonLinear Option Pricing) didn’t think there
was any info on how to price options in Nassim’s Lecture.
– Any distribution using a financial time series sample space
would be finite and thin-tailed with compact support in time and price.

About caustic

Hi i there My name is Bryan Downing. I am part of a company called QuantLabs.Net This is specifically a company with a high profile blog about technology, trading, financial, investment, quant, etc. It posts things on how to do job interviews with large companies like Morgan Stanley, Bloomberg, Citibank, and IBM. It also posts different unique tips and tricks on Java, C++, or C programming. It posts about different techniques in learning about Matlab and building models or strategies. There is a lot here if you are into venturing into the financial world like quant or technical analysis. It also discusses the future generation of trading and programming Specialties: C++, Java, C#, Matlab, quant, models, strategies, technical analysis, linux, windows P.S. I have been known to be the worst typist. Do not be offended by it as I like to bang stuff out and put priorty of what I do over typing. Maybe one day I can get a full time copy editor to help out. Do note I prefer videos as they are much easier to produce so check out my many video at youtube.com/quantlabs
