Bill Gross Patents Way To Count

Mazel tov to Bill Gross on his patent for using arithmetic in certain ways! Here it is in patentese; here it is in English:

Bill Gross, who runs the world’s largest mutual fund at Pacific Investment Management Co., received a U.S. patent for the methodology behind a global bond index that weighs countries by the size of their economy rather than their indebtedness. … By focusing on gross domestic product, the index avoids concentrating on countries saddled with debt and offers a greater weighting for developing markets.

So hey that’s just super. I’m actually envious; I used to work in a field that back in the day would occasionally patent derivative trades for their tax/etc. advantages, but then the IRS/etc. realized that they could just look at the patents to see who was cheating – sorry, being aggressive – on their taxes. That’s kind of a hard sell to clients – “every purchase comes with a painful audit at no extra charge!” – and the days of patenting derivatives are kind of over.1

But patented indices lacks that you’ll-be-horribly-audited factor, and indices are a hotly competitive business for some reason. I’ve never entirely understood the business of licensing indices – it’s, like, licensing averages! I can average prices! I’ll sell you a spreadsheet for ten bucks! – but some of the appeal is obvious.2 Or at least more obvious post-Liborgate. An index maintained by a third party and licensed for profit is less likely to be manipulated, since the third party’s incentives are (1) to make the index reliable so they can profit from selling it to everyone and (2) specifically not to make it unreliable so they can profit from manipulating it, since they’re in the index business rather than the trading-the-thing-referencing-it business.3

That’s not Bill Gross’s business, though: he does trade the thing, rather a lot of it, and his goal in patenting this index is presumably less to profit by licensing it to anyone who asks than to profit by refusing to license it, making his the only GDP-weighted-in-this-particular-way bond fund in the land and thus competitively more desirable. Market-cap weighting by definition gives you average performance, and if the GDP weighting is better – which the patent application argues it is4 – then it should in expectation give you above-average performance. So you should be able to charge a premium for it, and you should want to keep your competitors from using it.

So, like most patent applicants, he’s looking for a monopoly, and seems to have gotten one, though arguably of a rather limited kind since there’s after all more than one way to use arithmetic and I am right now developing a bond index weighted by … I dunno, by something historically correlated with GDP. But there’s arguably another, more pleasing reason for Gross to want to keep his index restricted. If investing relatively small amounts in global bonds via a GDP weighting does create outperformance, then everyone should use it. But of course the more people who use it, the less edge Pimco will have: investment strategies that reliably outperform attract imitators until the outperformance dissipates.5 If Bill Gross’s patent can delay others’ efforts to pile money into his strategy, that doesn’t just protect his stream of fees from investors in his funds, it also protects their performance.

1. Some patents still lurk in equity-linked securities, though I don’t think anyone ever enforces them. Much the same can be said for silly acronyms – back in the day, I guess, before my time, there was some marketing value in telling a client “do a trade with our VIPER group!” Then everyone realized that that was idiotic.

2. Though there is some daylight between “ETF providers, financial advisers etc. should license third-party-provided indices” and “you should be able to patent those indices,” but whatever. Our patent system is broken, discuss amongst yourselves.

3. Also, I idly speculate: you’d have some incentive to keep the index limited to some number that reasonably relates to the amount of stuff underlying it. One goofy aspect of Libor is that it indexes this tiny-to-nonexistent market, but there’s like eighty bazillion dollars of derivatives tied to it, so you could profitably manipulate the eighty-bazillion-dollar market by trading in the much smaller cash market. (Except you don’t have to because you can just make up a number for the cash market, but that’s a separate issue.) Ideally you’d want to license a bond-market index, say, to institutions that represent only like a fraction of the total principal amount of the underlying bonds, rather than a huge multiple. Charging licensing fees lets you do that; arguably part of the problem with Libor is that everyone was free to reference it so the dopes setting Libor had a huge impact on the world financial system without necessarily meaning to.

4. Because it doesn’t overweight overpriced assets, doesn’t overweight bad credits with lots of debt, has countercyclical features insofar as debt prices often drop with GDP growth, and generally speaking based on historical data “would advantageously provide an investor with higher returns for a given risk level than would a market-capitalization weighted fixed income portfolio.” Bloomberg tartly notes “The Global Advantage Bond Index is used as a benchmark by the $5.24 billion Pimco Global Advantage Strategy Bond Fund, which returned 7.2 percent this year, trailing 58 percent of peers.”

5. At the extreme, if everyone uses it, GDP weighting converges on market-cap weighting, meaning that a country with ~10% of world GDP and rather less than 1% of world debt would … well, its debt would get pretty rich pretty fast. TBF the Pimco patent lets you use derivatives, presumably in part to mitigate this issue.

    He should patent that haircut. Me-Yow

    "By focusing on gross domestic product, the index avoids concentrating on countries saddled with debt"

    So relatively large nominal GDP = relatively unencumbered by debt? Awesome…

    If you are purely in the index-publication business, it behooves your business to create an index that can be outperformed. Your customers want to be able to say they "beat the index" they have advertised as their benchmark. JPM's EMBI index (index of EM bonds) was excellent in this regard, as it disregarded the return from repo specialness, and many, many of the bonds in the index traded highly special for long periods of time. So much so that there was a market for EMBI/Libor swaps and for long periods you could receive EMBI and pay Libor less 100bps or so.

    love the "correlated with GDP" link

    The happy hunting ground for stupid acronyms back in the day was structured products: Merrill had LYONS (Liquid Yield Option Notes), Bear had STARS (Short Term Auction Rate Securities), and I think UBS or PaineWebber had TIGRs (no clue); also recall seeing MARS and PARS.

    • guest says:

      Salomon Brothers invented CATS–Certificates of Accrual on Treasury Securities. Merrill Lynch introduced TIGRs (Treasury Income Growth Receipts), and Lehman Brothers created LIONs (Lehman Investment Opportunity Notes).

      Now why you gotta go and say that about me?

    • Convexity Cat Food says:

      Don't forget FELINE PRIDES!

      -Guy who thinks Frank Partnoy could probably do a great paper based solely on odd structured products he's heard of.

      Treasury Income Growth Receipts. Mad that I remember that.

  8. engineer over here says:

    All the honies on the block are going to be all over PIMpCO's big new index.

  9. Matt's Mind says:

    Coming soon: Matt's Marg* Index!

    *Meh, not really sure what it will measure, but it will require lots of charts, so that's nice.

  10. HP-12C says:

    I didnt patent PMT or CHS and I'm still the sh*t so lets not pretend that IP law determines winners

  11. Seeing these showcase inspires me. That said, I like to look up new concepts in hopes to see more from here. Thanks.
