The Proper Next Chapter is ...?

<t>QuoteOriginally posted by: PaulHow about we work backwards. How much money do governments have lying around? A couple of years ago there was no money to pay for all manner of good works, now governments merrily announce the size of a new bailout by adding a zero to the size of the previous one. N...

The Proper Next Chapter is ...?

<t>While I see a huge deflationary process going into the next couple of years, I shudder to think of what kind of inflation will set in if there is a sudden upturn in consumer confidence. Something as simple as discovering a new massive source of Oil/Natural Gas may do it, and a bubble of epic prop...

Mr Nassim N Taleb on the warpath

<t>The fundamental problem can only be solved if people are willing to accept high short-term volatility in exchange for mitigating large deviations (you want thinner tails? then you _have to_ accept fatter shoulders). Since humans have finite lifespans and finite careers, they will always prefer sh...

how to prove if mean reversion exists

<t>You could use the Hurst Exponent. An Hurst exponent < 0.5 will lean towards mean-reverting behavior and >0.5 will show persistent behavior. From the wiki link:"In fractal geometry, the generalized Hurst exponent, named H in honor of both Harold Edwin Hurst (1880-1978) and Ludwig Otto Hölder (1859...

Tools for independent research

<t>I currently run Bricolage Labs, an open laboratory for self-experimentation and trial-and-error. People can capture their hypotheses and experiments there, share them with the community, and vote-up interesting and useful results.I'm thinking of expanding it to offer tools for researchers who are...

Vanilla option valuation: A priori knowledge of drift

<r>For a vanilla european option on an equity, does a priori knowledge of (well behaved) drift change the option valuation? Why/why not?I'm not able to capture the intuition behind the following paper:<URL url="http://papers.ssrn.com/sol3/papers.cfm?abstract_id=240793Thanks"><LINK_TEXT text="http://...

Diversified long OTM options in the real world

<t>What are the ways to go long a large number of OTM options in the real world (outside of options markets)? Would involve starting a business, so far I've been able to come up with:1. Publishing (music, books, art)2. Movie studios (similar to #1)3. Venture Capital4. Patenting (credit to Collector,...

Trading Kurtosis

<t>I understand there are two ways I can set up a long kurtosis trade on a given underlying:1. "Ratio Backspread" where I go long multiple OTM strangles for every short ATM straddle of the same maturity as long as I make sure it's a credit spread. 2. A calendar spread where I go long the far-term AT...

Falkenstein on Taleb

<t>Hmmm...odd. I didn't delete any of my posts. gardener3's post in between my two replies also seems to have disappeared.

Falkenstein on Taleb

<t>I think you're making an implicit assumption that option prices in the far tails have a well defined mean. I do not want to go into the infinite variance argument (kurtosis brought it up once, and that thread went nowhere), but I will say that if there's any doubt about it I'd like to be on the r...
