Obligatory Brexit ex-post (Survival, Skew, Politics & Data, )
This is a two component put up which blends my preferred topics: finance, economics, and politics. It's approximately the beautiful victory of the "leave" campaign that has left the UK dealing with a period of serious uncertainty.
Part one is an ex-post update on whether my portfolio was as robust to Brexit as I hoped it would be in my last post. This is based on market moves on Friday; of course things will continue to move as the full ramifications are digested.
Part two explains how Brexit was a classic negative skew event in more ways than one, how behavioural finance can help explain that, how it was mispriced by the markets, and how I used that information to make a little bit of money.

Did I live on Brexit?
Yes.
Let me expand.
Trading in GBPUSD
I made no cash in any respect trading cable, the asset maximum uncovered to Brexit. In fact I lost a few. When I wrote my final publish I had no position in GBPUSD IMM futures. However the swings in sterling sentiment were reflected in first a sell:
11242 GBP 201609 2016-06-15 02:38:sixteen -1 1.412600
And then I closed that as GBP went more potent within the put up Jo-Cox* soar in stays polling figures.
* It feels wrong to be talking about her tragic death in a grubby post which is mainly, at least at the moment, about money. However it seems likely that what happened to her was clearly linked to the referendum campaign. I had the privilege of briefly seeing her in person. She was on the select committee which I appeared before last year (16:20:00 on the timestamp of the video feed onwards), and I was very impressed with her performance. I'll be doing the politics of this later.
11296 GBP 201609 2016-06-17 18:54:08 1 1.434800
As with a regular fashion following system in a selection sure marketplace I bought low and bought high. And a similarly starting buy nearly exactly 24 hours before the end result would emerge as clear, as the sector decided remain changed into a shoe in (extra about this beneath).
11461 GBP 201609 2016-06-23 02:51:forty one 1 1.483000
Then, of direction it all went incorrect. The pound were given smashed. With a reversing fee and volatility going thru the roof, the system closed out it is position.
11509 GBP 201609 2016-06-24 03:54:26 -1 1.366400
Although the rate persevered to collapse it to around 1.33 then recovered, and closed at pretty tons the identical degree. As I'm penning this the pound is drifting decrease, however I haven't any position to take advantage of this.
I lost the equal of almost 2% of my portfolio on that one lousy GBP contract, about 1.25% of which changed into lost on the day.
The rest of my futures portfolio
Fortunately, as I stated in my last publish:
"It doesn't even appear to be a strong "hazard on" or "hazard off" theme, although I look to be a bit bit more "hazard off"."
Yeah, I were given that proper. I made it all again on the rest of my portfolio. In order of importantce: US bonds and Eurodollar, German bonds (makes feel), Korean bonds (who'd have though it - Korea a secure haven from the United Kingdom...), French bonds (the irony) and JPYUSD (though I gave that all back on AUDUSD).
I had no role in Gold, however you can't have everything.
I misplaced a piece on quick positions in VIX and V2X.
Net-internet on the main futures portfolio I made a bit under 2.Five%. Not as plenty as Crispin Odey is meant to have made, but then I might believe he could have hurt plenty more than me if the end result were as expected.
The point here isn't always a lot "ooh look I made cash is not my gadget clever" - it's miles natural success how a lot each person makes on a single day, but that my hazard became nicely controlled, such that a 6 sigma event in the markets translated into kind of a 2 sigma portfolio pass primarily based on my predicted danger going into the vote.
Equities, foreign money and hedging
Again, from the submit:
As I've stated earlier than my futures buying and selling account is funded by using a protracted inventory role, that's in a combination of UK shares and a European ETF IDVY; hedged by way of a Eurostoxx futures short. This is a greater interesting little portfolio; ignoring the effects on stocks if the pound gets hammered then in GBP phrases this portfolio will cross up in fee - there might be a advantage inside the fee of the ETF however the futures hedge won't flow considering it is unaffected with the aid of forex movements.
I was close here. The Eurostoxx did get hammered, more than the FTSE so I got that wrong. However it did indeed lose less in GBP terms because of the devaluation. Also the UK shares I hold in this account didn't do half badly. Net-net the long stocks plus hedge added another 2% or so.
I also have a protracted most effective, buy and hold, portfolio of UK stocks and ETF's covering bonds and equities throughout the globe.
Here are some extra fees from my Brexit post:
The ETF's aren't forex hedged, so a GBP devaluation following brexit could benefit them
This is exactly what passed off. The most effective ETF in my most important portfolio that fell in ? Terms was a excessive yield Eurostoxx beast, which suffered from the big fall in banking stocks which wiped out the EURGBP revaluation advantage. All my other ETF's have been up in ? Terms.
The effect on shares is a bit tricker to expect, however I would consider my UK shares might harm - perhaps five% at worse? A massive at some point drop with a view to possibly be partly reversed, however no longer the stop of the sector.
The FTSE100 changed into down 3.2% at the close, the FTSE 250 7.2%. So on common five% turned into an excellent guess. Some of my UK stocks did an awful lot higher (Glaxo was up), others tons worse (Intermediate Capital Group changed into finished over 14%).
Overall in my long only account I became flat.
This isn't genius trading, but as a minimum if the e-book sales fall quick then I should probable get a job as a chance analyst.
All of this is on a T 1 evaluation. We do not virtually know how things will pan out over the following N years while this little mess gets looked after out.
Brexit as bad skew
Cameron, David
I tweeted loads on Friday. Here is one in every of my first efforts:
https://twitter.Com/investingidiocy/status/746240000073728000
"Cameron took on the traditional brief vol change - high opportunity of success, small upside, huge downside. And lost. #brexit"
That is quite self explanatory. Cameron acted like a muppet strolling a hedge fund.

| "Muppet" is a term of abuse in the south east of England meaning "Idiot". I don't mean an actual Muppet. I have a lot of respect for Kermit. I think he'd make an excellent hedge fund manager. Source: https://autonomousmind.files.wordpress.com/ |
Your common muppet HF manager will preserve selling OTM alternatives. They saved expiring with out fee, leaving him with the top rate. He begins to confuse success with skill; he thinks he changed into invincible. This is the classic behavioural finance effect of overconfidence. Then at some point, he blows up.
Why changed into the referendum like an OTM choice?
Firstly, it gave the impression of a forgone conclusion. Promising a referendum was a reasonably-priced way to conquer down the nascent UKIP vote in final years election (the vote nevertheless hit historic highs, however thanks to our bonkers electoral gadget they had been not able to gain focused help to win multiple seat in parliament). It could be so clean, only a 1/2 baked (and suspiciously quick) negotiation with the EU to get superficial concessions, hold the referendum, bish-bash-bosh with the accessible aspect effect of destroying his most important political rival (By which I suggest Boris Johnson. Not the labour celebration).
Yes there were some worrying moments, but he never seemed ruffled, or appeared like he ever concept he might lose. This appeared like a excessive possibility occasion, but the drawback, which doesn't appear to have been nicely considered, become widespread - each politically and individually.
Secondly, it had a small payoff if it succeeded. Without the referendum I assume it's miles distinctly not likely that Boris would be a severe contender for PM.
Thirdly it had a massive fee if it went incorrect. Both in my opinion, politically and economically.
Overconfidence often seems to have an effect on humans from privileged backgrounds.
The whole u . S . Is deciding to buy the fact that Cameron has had a easy direction via existence with not anything going honestly wrong. There are many articles within the press mentioning how he's been lucky with several political gambles over the years. Even having to enter coalition with the Lib Dems become a blessing, giving him an excuse to maintain the right wing of the birthday party at bay whilst retaining Nick Clegg in front of himself to take all the flak for the politics of austerity.
All this made him assume he become invincible. Similar (dare I say?) to the careers of many financial traders and asset managers, a lot of whom come from privileged backgrounds and who sailed thru lifestyles with out failing at some thing*, who stressed success with skill, became infected with the fatal ailment of hubris; earlier than the inevitable blow up.
* Full disclosure: The author of this blog was privately educated and was admitted to the worlds best university (the first generation in his family to go on to higher education, make of that what you will), but soon found he wasn't as clever as he thought he was, and left after one year. A series of random unconnected jobs followed. On first coming into contact with the financial sector with a job as a trader he hated it. So yes, I've been lucky, to have screwed up my life royally many many times.
Finally both hedge fund managers and David Cameron have the benefit of a fairly soft landing if matters move incorrect. Collecting 2 and 20 for some years on some hundred million or extra can set you up for lifestyles. Cameron has more than enough private wealth, his wife nevertheless works, and even along with his ignominious exit could without difficulty rack up a few million quid a yr "advising" banks and private equity firms (a case of "don't do as I did, do as I say"?).
A fair payoff for poor skew
Now, taking negative skew bets isn't automatically a bad thing, if they're fairly priced. The minimum one should accept is something that gives you zero expectation. Ideally you'd get more than this, a lot more, since most reasonably people have a utility function that hates negative skew.
So if the probability of an event is P, and the payoff is a, with a loss of b if the event doesn't happen:
b>a (definition of negative skew)
aP > (1-P)b
NOT a black swan. A white one with one gray feather
Before I retain, I'll just point out that Brexit become NOT a black swan - an unbelievable event with a tiny opportunity of occurring. Even at the widest odds the implied possibility of the occasion become extra than 10%.
The City, The Bookmakers and The Polls
It wasn't simply Cameron who got the opportunity of this event wrong, it became anybody.
On the day before the referendum implied foreign money volatility became pricing in something like a 20% risk of Brexit happening:
"@investingidiocy on BBG, prob derived from FX options for depart is 19% - however guessing the spread is huge to do the arb exchange!!!"
twitter with thanks to Saeed Amen
Similarly on the betting markets the decimal odds on betfair were additionally implying roughly a 20% hazard, although this was moving round (see picture - now not updated, however gives you an concept of the volatility)
It changed into clear to me that 20% became a long way too low. See those opinion polls.

Notice that:
- The vote was on a knife edge; with neither side getting a clear advantage (say 60:40) in any poll
- There is considerable variation across time
- There is considerable variation across polls
- The undecided figure, although narrowing over time, was still averaging about 6% at the end - easily enough to swing it one way or another.
- Polls have margins of error (MOE), which are shamefully absent from public discourse. Most polls of the size done in the referendum campaign would have MOE of 3-5%. Polls of polls have a smaller MOE; maybe a couple of percent.
Personally I notion on Thursday that given the very last ballot of polls determine of 48:46, with undecided at 6%, and an MOE of multiple percentage.... Nicely this wasn't an occasion with only a 20% risk of occurring. It became quite close to a coin flip; but permit's call the percentages of continue to be P=60%. But the ratio of the 2 payoffs in the having a bet marketplace changed into extra than five.0 (decimal odds of one.2 and 6.0 respectively). So the expectation of the 2 alternatives is:
0.6 x 1.2 = zero.Seventy two
0.4 x 6.Zero = 2.Four
The 2d alternative (betting on go away) is sincerely greater appealing than the second.
Why this apparent mispricing? Well the markets (making a bet and FX) circulate depending on weight of cash. Mostly rich well knowledgeable people of a higher social magnificence play in both markets. Exactly the type of people who voted remain. They left out the polls and focused on their very own prejudices. Again this is behavioural finance at work. Could be certainly one of several outcomes, however lets go along with narrative bias. The "tale" that Brexit became horrible and no person might vote for it changed into extra attractive than the statistical evidence within the polls.
That is the unique impact. But normally people are sincerely horrific at understanding records whilst measured with uncertainty; and this is mainly dangerous when the outcome is binary - people will certainly try and assign possibilities of a hundred% and 0% to binary options.
My little flutter
So how quality to make the most this? A truthful manner would be to promote GBP eithier in USD or EUR. Or do the equal aspect through alternatives, despite the fact that be aware that shopping for OTM options is an costly business because of the unfold. You can also guess on the outcome.
However despite the fact that all of those bets have effective expectation, it'll additionally on average lose money (assuming there was say a 60% chance of continue to be). Since we will only guess on brexit as soon as this is fairly annoying.
I opted for a combination trade (and here); a bet on Betfair on Brexit, and a purchase of GBP against EUR (so a bet on remain). I sized the latter trade so that my expected payout in the event of eithier remain or leave would be the same.
Actually I probable got the dimensions wrong. I doubt that GBPEUR might have rallied enough with a stay vote to make up for my loss on Betfair. The ensuing depreciation of GBPEUR become additionally surprisingly small; as it turned out Brexit is horrific for Europe as well and all the capital fleeing to safe havens went to America - it was GBPUSD that surely were given crucified.
As a result I ended up making much more than I expected (also here) on a leave vote. However this was a fun trade done for relatively small amounts of money. This kind of global macro discretionary trading isn't my forte. It seems like a lot of work.
Summary
Generally betting on a coin toss isn't a terrific concept, except the market is mispricing the chances of heads as just 20%.
However these possibilities are few and a ways between, and require quite a few work and analysis. Systematic buying and selling is far easier. A nicely structured (different, hazard managed) funding portfolio or trading device will now not be prone to shocks like Brexit.
So I made some money. I take actually no pride on this because I in reality feel it became the incorrect decision with a purpose to have, and already has had, terrible effects (each economically, and ina sharp upward push in racism). There is already dialogue that Brexitmay in no way certainly take place; I wish that is the case.
