The Greek letter gamma (γ) is used in finance to denote correlation, the "connectedness" of two separate events. For example, if patient A dies of malaria, how likely is it that patient B will, too? If it is absolutely certain that he will, correlation is total and γ has a value of +1. If it is certain that he will not, then the two events are completely uncorrelated and γ has a value of -1.
Assigning proper correlation values is crucial in the design of tranched derivative products that contain many separate instruments. For example, CDOs structured from thousands of individual home mortgages, auto or student loans.
For an excellent story on correlation see this Wired magazine article: Recipe for Disaster: The Formula That Killed Wall Street by Felix Salmon.

It did not take Neo very long to become adept at dealing craps the Quantum Casino way. All he had to do was call the shots - just a split second before every gambler at his table had a chance to "see" how the dice lay. Neo's manipulation of perception created reality as he - and the Casino owners - wished it to be.
And in the Quantum Casino's version of reality almost every gambler got properly "skinned" the old-fashioned way: by regular and frequent swaps between greed and gloom.
Not long thereafter, and based on the tremendous profits his new game racked up for Quantum Casinos, Inc., Neo was made a partner. His future was set.
And in the Quantum Casino's version of reality almost every gambler got properly "skinned" the old-fashioned way: by regular and frequent swaps between greed and gloom.
Not content with swindling the same old geezers, Neo soon tired of the regular games and looked for added excitement. He designed a brand new game employing multiple variables that provided small, but regular, payoffs every time the variables did not align together - which was most of the time. But when they did converge everyone lost big, including their prior winnings. He called it The Correlation Game - and it proved to be a bonanza.
Neo realized that people loved repetition of familiar patterns - the herd mentality, he called it - and supplied it with gusto. He skillfully manipulated results and repeated gains to create a seemingly simple and profitable pattern - until he led everyone right over the edge, of course.Not long thereafter, and based on the tremendous profits his new game racked up for Quantum Casinos, Inc., Neo was made a partner.

A few - very few - professionals have tried to explain how they "see" markets but their work is usually ignored or scorned by the "reality-based" community of professors, analysts and consultants who prefer deterministic theories, such as random portfolio, etc.

Here are two examples of really smart guys that "got it":
- "Reminiscences of A Stock Operator" is likely the best book ever written on speculation, recounting the life of Jesse Livermore. Aptly in keeping with quantum physics, please note that "speculatio" is Latin for observation.
- George Soros rejected Adam Smith's supply and demand and instead used "reflexivity" as "The New Paradigm for Financial Markets".
Needless to say, both individuals were extremely successful. In addition, Soros' premier hedge fund is named The Quantum Fund. A coincidence?
I will say it again: it is perception that shapes reality and not the other way around. Does this apply to today's crisis? Yes, it does. If we believe that "this is the biggest crisis since the Great Depression", then our belief will be realized because our behaviour will be altered to fit our preconception.
Therefore, one has to seriously wonder why all the smart analysts are crying oceans of tears for all the horrible things that are supposedly coming our way, while Neo (aka Fed, Geithner and Co.) are furiously pumping trillions of fresh dollars into the system.

Yes, she's back. Who? Goldman's strategist Abby Joseph Cohen has just said that US banks are "still not in the clear".
This is what I wrote about her in a post back in December 4, 2007.
"Abby Joseph Cohen of Goldman Sachs and 1999-2000 stock bubble infamy, just came out saying that the S&P 500 will climb to a record 1,675 by the end of 2008, extending the longest stretch of annual gains since the 1980s.
She is one of the best contrary indicators in the strategist camp. Back in 2000-01 I made a point of shorting every time she came out with a bullish hoo-hah. I think she stayed bullish until 2003 and then turned bear. Just in time."
S&P 500 was at 1,510 when she made that pronouncement and managed a 10 point rise over the next couple of days. It then went a whole lot lower, of course. The index is now at 798 and she thinks "it's not over", eh?
Well, I bet she's still the best contrary indicator around - and fervently hope Goldie keeps her on the payroll forever. And ever.
