"'No one really knows how to price asset-backed securities and CDOs and that's a real problem in the market place now,' said [AR], principal of R&R consulting, a [SF] consultancy in New York", WSJ, 10 August 2007.
"'Do you believe? Then place your hands over your investment portfolio and declare your faith in the ones who swear to its goodness', [said] Bob Moon.

"'Who are we going to trust? Are you going to look to JPMorgan or Goldman Sachs? Are they going to rate structured deals? Can we trust them on valuation? We need to take the high road ... because I might not do any better.' ... 'The problem as I see it, as we at R&R see it, is a fundamental lack of recognition of the different basis that exists in [SF] as opposed to corporate finance. ... Valuation ... is the only problem for finance,' [SR]. Raynes then asked how do we move forward from here: 'The first thing I would try to do is to establish a unique valuation theory for structured securities. Does this exist? Well it could if people are listening. They are not. ... '[SF] is a beautiful thing. The men of Wall Street like to fall in love with beautiful things. ... So we don't have to be in love with [SF], we just have to respect it'," http://www.prmia.org/, 25 September 2007.
"No one really knows how ... now", saith AR. Was the knowledge lost? Who ever knew? AR admits she doesn't know. Later, I will offer a suggestion using mutual fund accounting which I understand. "If you give me six lines written by the most honest of men, I will find something in them which will hang him", Cardinal Richelieu (1585-1642). Yes!
"The solution for the subprime-infected credit market seizure that wiped out $66 billion of securities industry capital this year may be found in a bunch of hospital bills. ...

As much as $2 billion a year could be made by someone with a model that accurately valued asset-backed securities, according to [SR], a principal at R&R Consulting in New York. ... Dan Fuss, vice chairman of Boston-based Loomis Sayles & Co., hasn't found an adequate system to help value CDOs so he refused to include them among the $22 billion of securities he manages. ... Raynes of R&R Consulting was hired two years ago by an affiliate of the Bond Market Association that deals in asset-backed debt to assemble teaching materials on valuing such securities for its members. The trade group paid Raynes half of his fee in advance and failed to pay the remainder after receiving the materials because its members found them too complicated. 'All of the managing directors could not understand any of the formulas so they did not pay us,' he said. 'This is basic bond math, duration and convexity. This is not rocket science. ... Firms promoting new pricing models are 'trying to cash in on fear,' Raynes said. ... We as a market must recognize there is a lack of understanding of what value means in [SF]'," Caroline Salas at http://www.bloomberg,com/, 4 December.
I suspect 73 years from now Graham & Dodd's Security Analysis will outsell SR book. I agree with SR, most ratings are worthless. I disagree with SR, we don't need a "different basis" for SF as opposed to corporate finance valuation. SR belief is pure faith. He believes, I do not. Cash flows are cash flows. Discount rates are discount rates. Consider "arbitage pricing theory" (APT). APT came out in the mid-1970s. I still pick up finance or economics books from time-to-time to keep up.
Are Wall Street MDs as dense as SR thinks? Most went to our better MBA schools: Wharton, Stanford, MIT, Northwestern, Harvard, Columbia and my alma mater, Chicago. Their inability to understand basic bond pricing surprises me. At Chicago, many years ago, I took Rueben Kessel's class on the "Term Structure of Interest Rates", which touched on concepts like duration and convexity. So? Don't MBA schools teach that any more?
SR may be wrong; cash flows are cash flows and their "wrapping", in a corporation, an SIV or a tortilla, only changes their tax and legal attributes. As Cassius said to Brutus, "The fault, dear Brutus, is not in our stars, but in ourselves, that we are underlings", Julius Ceaser, I:2. Similarly, the fault dear SR may be: cash flows are cash flows! Further, do not try to be more precise than your data permits. A humbling book decrying excessive precision is: On the Accuracy of Economic Observations by Oskar Morgenstern (OM), 1950. OM's opinion: economics is at most a "two-digit" science. Be warned. By the way, OM was a Princeton economics professor. I wonder if his name is even mentioned on that campus today.
Mutual fund pricing values each position, using current market prices, adding up the value of all positions, then dividing the total by the number of oustanding shares for a unit price. Simple, voila. We get a few "hooks". If we invest in a "load fund", with say, a 5.75% fee, when we invest $10,000, we only see $9,425 ($10,000 - $575) on our statement. Easy enough. What has this to do with CDOs? About 30 years ago, we had "dual funds" (DF). DF had "common" and "preferred" shares. The preferred shares got the underlying investments' dividends and the common shares the rest. DF were interesting since in theory, you could buy an equal number of common and preferred shares to recreate the underlying portfolio on an unlevered basis. Some academic work was done on why common and preferred shares sold at premiums and discounts. That's not germane to my discussion here. What is: the common and preferred shares together, sold at a discount to the underlying portfolio. Why? The costs of running the DF were "impounded" into the shares current market price. Neat, huh? The market rarely is stupid. What has this to do with CDOs? Simple, how many "tranches" you break mortgages into doesn't matter; in total, they are worth the mortgages! Less administrative costs, of course. Just like DFs. The valuation problem is not with CDOs, but with the underlying mortgages! It's on the ledger's asset, not liabilities side! Wasn't that easy? As to valuing the tranches, just use bankruptcy law concepts as to their seniority, bearing in mind, at some point, even a "deep out of the money" tranche, has option value. It may be one dollar on 100,000, but some value. Debits to the window, credits to the door. Class dismissed. For extra credit read, "The Theory of Recapitalizations And The Evidence Of Dual-Purpose Funds", Litzinger & Sosin, The Journal of Finance, Vol. 32, No. 5, (Dec., 1977) 1433-55 which deals with contingent claim valuation. Speculation: what interest rate would Citigroup have charged a person with a $100 million mortgage portfolio to borrow $85 million against it and create his own "toxic waste" dump? Just curious, more or less than the mortgages' interest rate?
"'The first step if you are an alcoholic and you need to stop drinking is to get on the podium and admit to yourself you're an alcoholic.' ... Raynes said", http://www.bloomberg.com/, 4 December. Amen. That's good Bill Wilson advice as millions of AA members can attest. Try this, "My name is Sylvain. I am a structured finance professional. ... " Sylvain, after the meeting we will introduce you to people who have at least a year in the program so you can pick one to be your "sponsor".
$2 billion a year? Is SR looking for a "philosopher's stone" that will turn lead into gold. I have a better idea SR, if you find the "mother of all valuation models": keep it to yourself and use it to select stocks to purchase and short. If the model works, it should enable you to make some real money. Had you known how to value CDOs, etc., a year ago, you could have made a nice profit shorting: Ambac, MBIA, Countrywide, Citigroup, etc.. Tens, maybe hundreds of billions a year could be available to you. See my 23 August, two 27 September and 24 November posts.
