ET Pro In Summary

(December 1 – December 7, 2018)

Professional investors are wrestling with four big concerns, what I call the Four Horsemen of the Investing Apocalypse:

The Four Horsemen of the Investing Apocalypse

  1. The Fed keeps on raising interest rates and shrinking its balance sheet, ultimately causing a nasty recession in the US and an outright depression in emerging markets.
  2. China drops the trade war atom bomb by letting the yuan devalue sharply, sparking a global credit freeze that makes the 1997 Asian financial crisis look like a mild autumn day.
  3. Italy and its populist government play hardball with Germany and the ECB in a way that Greece could not, leading to a Euro crisis that dwarfs the 2012 crisis.
  4. Inflation, particularly wage inflation, gets away from the Fed, as their monetary policy tightening forces corporations to increase their risk-taking.

Humans are biologically designed to pay attention to one big thing at a time, and our media stimulus machine knows it, so every week the “story” of what’s driving markets up or down will be good news or bad news on one of these concerns. Two weeks ago the story was Jay Powell finding that old-time dovish religion, which markets loved. This week the story was Trump starting the clock on a trade war game of Chicken with China, which markets hated. In truth, of course, there is “news” about all four of these concerns happening all the time, but until further notice … if you want to explain the WHY of your portfolio to your clients or your board or your CIO or whoever it is that you have to explain yourself to, you’ll need to explain it in terms of The Story of the Week. Because even if you’re not utterly focused on that Story of the Week, THEY are.

And for the next 90 days, that Story of the Week is most likely to be the China trade war story.

Why? Because it’s got a ticking clock. Again, we are biologically hardwired to respond with full attention to a countdown to disaster (the core brilliance of the TV show “24”), and again, our media stimulus machine knows it. 

The easiest prediction I’ll ever make is that CNBC constructs a “Countdown to Trade War” video graphic over the next month or two, literally counting down the days until China-US relations detonate.

Talking about the China-Trump trade war game of Chicken is good business for CNBC and Bloomberg and all the rest, so talk about it they will. Even if there’s nothing to talk about. Actually … especially if there’s nothing to talk about. And when they do talk, I promise you that 95% of that airtime will be spent asking this guest or that guest (I would say “expert”, but in a world where Kevin O’Leary is treated as an expert in everything from algo construction to Sino-Japanese foreign relations, I’ll stick with “guest”), about the “chances” of a deal being struck anytime soon and the “likelihood” that the deal will favor the US or China.

So, Kevin, what should we do in Ukraine?

Let me be really clear about this.

Anytime that anyone talks about “chances” or “odds” or “likelihood” in the context of a game of Chicken, like this trade negotiation between the US and China, they are talking nonsense.

There are no odds in a game of Chicken.

It’s one of the hardest concepts in game theory to wrap your head around, but maybe the most important. And it has enormous consequences for how to invest over the next three months.

Chicken is a game with two equilibria – two potential outcomes for the game. You can see this mathematically in the stylized 2×2 game matrix below, with the equilibrium outcomes circled in gold, or you can just think about every game of Chicken you’ve ever seen in the movies. I’ll use “Footloose” for my example, because … Kevin Bacon. I mean, c’mon.

Both Ren (Kevin Bacon) and Chuck start in the bottom right corner of the matrix. They’re both driving their tractors straight at each other. Both are faced with a decision. Do I continue to drive or do I jump off my tractor? If they both do nothing and stay in the bottom right corner, then both players have a TERRIBLE pay-off (-100 for both Ren and Chuck). This is NOT an equilibrium, because at least one player (in this case both players) can get a better pay-off by changing their strategy from Drive to Jump.

If Ren (the column player) jumps, then the column strategy changes from Drive to Jump and both players are now in the bottom left corner. That’s a better pay-off for both players, but a LOT better for Chuck (+10) than for Ren (-10). This IS an equilibrium because NO player can get a better pay-off by changing strategies from here. Obviously Chuck isn’t going to Jump now that Ren already did, so the row strategy isn’t changing, and obviously Ren isn’t going to get back on the tractor and start driving again towards mutual suicide.

But you’d also end up in an equilibrium (neither player will change his strategy) if Chuck decides to jump (changing the row strategy and moving both players to the upper right quadrant), which is a LOT better for Ren (+10) and still better than mutual destruction for Chuck (-10).

Hence the delicious tension of the game of Chicken. Hence the reason our media stimulus machine looooves a good game of Chicken. Either player can win. Either player can lose. All you have to do to win is have more willpower than the other player. That’s it. You don’t have to be physically stronger. You don’t have to be mentally smarter. You just have to “want it more”, to use the clichè of every hack sports announcer ever. But in a game of Chicken that happens to be true. You just have to want it more.

There is ZERO information about willpower in the structure of this game.

Zero. None. Nada. Rien. Bupkis.

Go ahead and change some of the pay-offs. Make them asymmetrical. Make it a -50 instead of a -100 for one of the players. Make it a +30 instead of a +10 for one of the players. It doesn’t matter.


Sorry for the shouting.

But I get so frustrated with some of the “analysis” that you hear about this trade war game of Chicken, especially this gem that you’ve already heard umpteen times and will hear umpteen-squared more times over the next two months:

“The US will win because China has more to lose in a trade war.”

This is nonsense.

It’s nonsense because it’s talking about the pay-offs of the game, not about the behavioral driver of player strategy – willpower. Pay-offs cut both ways. Sure, I’ve known people where ‘having more to lose’ makes them jump from their tractor first. But I’ve also known people who have MORE willpower in a game where they ‘have more to lose’.

Bottom line: it’s a fool’s errand to impute resolve from starting game conditions and pay-offs.

The only analysis that has any predictive usefulness in determining the winner of a game of Chicken is an analysis of exogenous player resolve. That’s a ten-dollar phrase that means you peer into the psyche of the players and figure out who wants it more.

So who wants it more, Trump or Xi?  

Anyone who claims to have an answer to that question is either lying to you and/or lying to themselves. Not even Trump and Xi can know the answer to this question! Again, this is the delicious tension and suspense of a game of Chicken – not even the players know who wants it more. The outcome of the game only and always emerges from the playing of the game.

It’s not that the odds of the game are unknown.

It’s that the odds of the game are unknowable.

Successful discretionary investment boils down to two things: edge and odds.

In the US-China game of Chicken, you have no edge. And you don’t know the odds.

Unknown information creates the potential for alpha, for the ability to discover valuable private information.

Unknowable information, on the other hand, creates zero potential for alpha. In fact, it’s almost always an alpha destroyer, as market participants convince themselves that they have an “edge” in predicting the equilibrium outcome. They don’t.

Unknown information lives in the world of investment RISK, where you can calculate the expected value of an investment (risk and reward) and the cost of acquiring additional information to impact that relationship. This is what professional investors DO, day in and day out.

Unknowable information lives in the world of investment UNCERTAINTY, where none of our expected value calculations work, no matter what you spend on acquiring additional information.

You can’t hedge investment uncertainty.

You can’t hedge investment uncertainty because it’s not just difficult to measure the risk to your portfolio (and please remember that risk isn’t just a loss suffered but is also a gain foregone). It’s IMPOSSIBLE.

So what do you do if you can’t calculate the risk in your portfolio?

You take down your book. You reduce gross exposure.

Look, at some point there IS a deal. Games ALWAYS end up in an equilibrium. One of the two sides will blink, a deal will be struck, everyone will declare victory, and we’ll see then what narratives emerge from that. Maybe it will be a market-positive narrative to emerge. Maybe it won’t. Regardless, whatever deal emerges is not an investment regime change, and it won’t be the end of the world or the engine of a new bull market.

You may miss a spike up if trade peace breaks out tomorrow. You may miss a week-long rally if a narrative of imminent peace takes root. So be it. I’m not saying to get short. I’m not saying to go long volatility.

I’m saying that you do not have an accurate picture of the upside and downside risks to your portfolio so long as the US-China trade war game of Chicken is the Story of the Week in markets. Not because you’re missing any crucial piece of information, but because the equilibrium outcome is unknowable.

I’m saying that when large institutional portfolios see more uncertainty in markets – not greater risk, but more technical uncertainty – they do not buy dips and they do sell rallies. They rebalance by selling winners, not by adding to losers. They take down their book.

You should, too. And you should do it first.

Taking down your book means different things to different types of investors and allocators. I’ve used the phrase “reducing gross exposure” because it’s an expression that’s most familiar to long/short hedge fund managers, who make daily decisions on gross and net exposure, and have well-established processes for moving these exposures around quickly. For investors with more static or long-only portfolios, the more familiar terms of art might be “tactical overlay” or “active risk” or “discretionary overweights and underweights”.

In all cases, though, taking down your book means one simple thing:

Get closer to your long-term strategic allocation and stop doing whatever it is that moves you away from that long-term plan.

This, too, shall pass. And relatively soon. You don’t have to dance every dance.

  1. Brilliant as usual!
    I have perhaps a silly analogy to golf. Any pin has four quadrants locally: uphill R to L, uphill L to R, downhill R to L, and downhill L to R. Every R-handed golfer knows that the Favored Quadrant is the first one and least favored is the last. Most attribute the difference to visual factors. Well maybe - but the better explanation (Pelz) is that both errors (push or pull) work in your favor in the Favored Quadrant and against you in the opposite. And yet I can tell you that in ten years of weekend caddying, not one loop ever asked me where to leave an approach putt or chip when out-of range. The Favored Quadrant optimizes a one putt chance but has no chance of sinking the out-of range preliminary , whereas an attempt to sink a low odds preliminary puts a 3-putt right up there. (Eventually, I expect Bryson deChambeau to putt from both sides to optimize both uphill quadrants.) Seems like Game Theory somehow! Cheers!! DrJohn

  2. China reality: US will win the short term trade war…its ECON 101. Long term, they will loose, because they are forcing China exponentially to become more self-sufficient and overtake the United States as the premier economic power. This is more than just economics this is about nation states, and future soft/hard power. Trump nation is the showpiece of an empire rotten and going down hill…2020 will be much worse!

    “AlphaZero’s ability to master three different complex games – and potentially any perfect information game – is an important step towards overcoming this problem. It demonstrates that a single algorithm can learn how to discover new knowledge in a range of settings. And, while it is still early days, AlphaZero’s creative insights coupled with the encouraging results we see in other projects such as AlphaFold, give us confidence in our mission to create general purpose learning systems that will one day help us find novel solutions to some of the most important and complex scientific problems.”

    "Its downside is that it’s a static world. It doesn’t have any vision of the future because the way it works is by constantly monitoring what you did yesterday and the day before, and the day before that. And monitoring what I did yesterday and the day before and the day before that and doing the same to billions of other people. And then looking at patterns and then saying: “If you liked that, you’ll like this”.

    “They’re constantly playing back to you the ghosts of your own behaviour. We live in a modern ghost story. We are haunted by our past behaviour played back to us through the machines in its comparison to millions of other people’s behaviour. We are guided and nudged and shaped by that. It’s benign in a way and it’s an alternative to the old kind of politics. But it locks us into a static world because it’s always looking to the past. It can never imagine something new. It can’t imagine a future that hasn’t already existed. And it’s led to a sense of atrophy and repetition. It’s “Groundhog Day”. And because it doesn’t allow mass politics to challenge power, it has allowed corruption to carry on without it really being challenged properly.”

    “Progress will require changes to existing institutions, creation of new institutions, and consonant changes in norms for both institutions and individuals. For example, there is clearly a need for greater world governance, but we have no non-utopian conception of the conditions of legitimacy for a strong international authority. In view of the plain facts about our world, global legitimacy can’t be designed by analogy with the conditions of democratic legitimacy for the nation-state. There is an upper bound to the divergence of interests, values, language, and culture that can be contained within a legitimate democratic polity. Yet eventually a new structure may emerge, through contingent historical developments, which will be governed by norms that could not have been recognized in its absence, but that become accessible to people who live in the world so structured.”

    “What we have is a growing gap between where power lies and where the institutions that seek to hold it accountable to the people operate. Such institutions are incapable of allowing democratically elected leaders to deliver their campaign promises. This is what is ultimately triggering social tensions and undermining trust in our democracies. We need our institutions to interpret these tensions as red flags and a call for a new social contract. And we need institutions to react now. This situation goes far beyond the debate around digitalization. Yet the online space is our future, and is therefore where this gap is most visible and urgent. If our current institutions of government fail to ensure the ongoing technological revolution puts people first, these institutions will sooner or later be rendered irrelevant.”

    You think about the above memes…stand bye! Ben Hunt and Rusty Guinn are on to something!

    My perspective is from a 29 year Special Operations veteran who knows reality…the only easy day was yesterday!

    The trade war is theatre for Trump and Xi and not winnable, there’s nothing to win at… if we really wanted to play this game, we would know that China doesn’t flinch at big, open, organized challenges and games of chicken; their greatest asset is not the AI development or the “Control” or the Party or the Army or “Good ‘long-term’ thinking and planning” or anything like that; it’s their people - if needed, their people as a whole will take a lot of crap and deal with it just fine and deal with it over and over again, like always; China’s weakness is the death by 1,000 cuts – all kinds of small things going wrong in all kinds of different places that appears random and unsystematic but really isn’t - so, purely strategically, the arrest of the Huawei CFO in Canada was 1,000x more effective than any tariff or import policy change or grandstanding could ever, ever be. It’s a random wheel that falls off the bus that they have to respond to or look weak. It was unannounced. And it was insulting and forced a response. The prize w/ China is never “winning” anything, the prize is the quantity of offensive-sounding, pissed-off responses that you can illicit so when they say Canada will face severe consequences if they don’t release Meng - that’s a point on the board. I don’t agree with extra-territorial arrests in principle but if one wanted to put a point on the board against China, then I think it was effective.

  4. My mindfulness time this morning was interrupted by my memory of an old ET post that had something to do with “Playing Chicken” and a screenshot of Kevin Bacon on a tractor. So I’m reviving this gem because, as far as I can tell it’s all relevant again.

    The Four Horsemen of the Investing Apocalypse

    1. The Fed keeps on raising interest rates and shrinking its balance sheet, ultimately causing a nasty recession in the US and an outright depression in emerging markets.
    2. China drops the trade war atom bomb by letting the yuan devalue sharply, sparking a global credit freeze that makes the 1997 Asian financial crisis look like a mild autumn day.
    3. Italy and its populist government play hardball with Germany and the ECB in a way that Greece could not, leading to a Euro crisis that dwarfs the 2012 crisis.
    4. Inflation, particularly wage inflation, gets away from the Fed, as their monetary policy tightening forces corporations to increase their risk-taking.

    Still pretty spot on. Might replace the word Italy with Banking Crisis, but pretty on narrative for today (4.5-ish years later).

    The chicken reference was actually the thing that got me thinking about it this morning though. Not about a trade war mind you, but about the debt ceiling. The ticking clock…
