    It is. I work in a similar vein of the industry as Taleb (derivatives trading, but at a bank). he is the guy who says we are undervaluing the chance of a crash every day of every year and once in a while, he strikes it big. he is the guy who plays the same strategy every day and says "told ya so" when it finally pays off. he's not a fool, but it's a self fulfilling prophecy if you believe in a cyclical market so it's hard to put much weight behind him.

    But, it's a cheap strategy to do in derivatives. You don't require much cash and since you are buying optionality, margin calls have a hard limit so it's less uncertain(to the downside) than other strategies.

    But he is right about VAR. it's not something that is hard for anyone to tell you who has worked at a bank. I can remember 2 distinct times where my main job was to find out how to reduce our var without reducing our actual market risks (in order to free up risk capital so we could take bigger bets) and it will be my job again in a few days as everyone starts repositioning for the new year.

    We have to do it in earnest because management always looks to the recent past to guess at your exposure to the future and generally, the models that VAR uses are far weaker than any modern pricing models or risk models because they are much harder to implement. the volatility of the last 18 months will cause/ is causing everyone's VAR to spike (even when carrying far less real risk) therefore adding to the massive de-leveraging management is requiring of everyone. this means over the next few months, one of the primary jobs of every trader will be obscuring the risks his portfolio is taking in order to take bigger risks (yeah, those incentives are still the same).

    now you may call me a pariah but after working in this industry for a relatively short period of time, I've come to realize that is all there is in it. this is how business is done, how it was done, and how it will be done. As shareholders continue to keep their boards in place, we are obviously doing exactly what a majority of our shareholders expect of us and that is our overarching mandate (and yes, I am not an investor in any of the banks anymore, even my own, because I realize to be a successful banker you are paid by shareholders to screw shareholders).

There are lots of other lines of arguments to refute the use of torture though.

    this was one of the most uninformed broadcasts I've ever seen (full disclosure, I'm a trader in fixed income derivatives, I work around this stuff all day and some nights). it doesn't give any real color as to what a mortgage backed security is, how CDO's work, what the tranches are and how you can get a AA security out of a bunch of non-AA underlyings, what mark to market accounting vs. hold to maturity accounting are and how they play into why banks have problems now but had amazing returns for the last several years, etc. It just gives a stereotypical view of what could have gone on in a limited way that perpetuates falsehoods.

    I can understand if you've never studied these products why you would think this is a useful broadcast. it does attempt to give a small picture of what was going on. but fails to highlight or give any information on the derivatives (those financial weapons of mass destruction "the sage" was talking about) or how they are structured.

    But to give you an idea that everyone seems to have no problem with, take a nice conservative bank. They are giving out loans to lots of people (none of whom are AA rated). Yet, they can turn around and sell bonds to finance their business at a AA rating. How do they do this? well, it's pretty similar to how CDOs work: you havea set of equity (in the CDO case, toxic waste or the unrated tranche; in the bank case, investor equity) that will absorb the first losses from a business (or a pool of credit assets). A bank with enough equity support can continue to sell bonds at a AA rating simply because that layer of protection shields debt holders from a certain amount of losses.

    It's why people will stop extending credit to a bank that lets it's equity decrease to below reasonable levels and why banks must recapitalize in order to continue operating: they can't finance themselves in the debt markets and will go bankrupt quickly without it (this is what brought both Bear and Lehmans down and what could have brought down Merrill).

    now, I'm not going to extol myself as an expert, but these are just a few of the many facets of this problem that people ought to get informed about so that they don't sound.... just stupid. keep in mind, I'm not trying to defend many of the practices that happened in the mortgage lending market (a lot of it disgusts me when I found out from a friend who did mortgage brokering for a short while before leaving in disgust). And I'm not trying to defend banks that over extended themselves or got caught on the wrong side of a very big trade but there are several reasons why only some banks have gone under while others are doing just fine (or seeming to do just fine).

    I think you should watch more sports. there is a MASSIVE shortage of highly skilled athletes in most sports (simply because in pro sports, the bar is set so friggin high).

    take the NFL: according to the players union, the average player only lasts for 3.5 years. But every player whose name I can remember lasted for 7+ years. So how does the average drop to 3.5 years? it's because a vast, vast majority of all football players that make it into the NFL don't even last for 3 years (Many don't make it past 1 year).

    With that kind of roll over in the pool of active players, it's easy to see why high profile salaries are so high. It's due to the fact that those high profile players are extremely rare and literally are the top 1 or 2 % of the top thousandth of a percent of all people who touch a football in their lives. Now, the minimum wage of the NFL protects the bottom most players from getting nothing or we would see a very steep payout in the NFL.

    now take the structure of all competitive sports: you can earn more in TV deals , ticket revenue, and merchandise sales if you are relatively better in the league. So the competition for fan dollars (which is limited) causes owners to try and buy the best possible team while keeping the franchise profitable. since there is a very limited supply of the best players, competition for their services drives up their price.

    now I am (or at least, was) a huge sports fan. I'm not sure what you define as world sporting events, but again, payouts seem to be linked ot how profitable the fan base is. Soccer players get paid huge sums of money, as do the best tennis players and golfers. Olympic salaries are reflected 100% in the advertising dollars they can bring in and we see again, that the best of the best get paid huge sums while those athletes in low profile sports get paid very very little to nothing at all.
