In investments, does more risk really equal more return, in the long haul?
Answer by Laurent Bernut:
This morning Palermo time, Andrew Swanscott from Better System Trader podcast interviewed me. The above question came up.
The answer is Yes and it is No, the real question is when. Best analogy is driving, will driving faster get You to destination: Yes when on the highway but No when in downtown.I define my identity as a professional short-seller. As such, I have a different relationship with risk than most people. There is an interesting paradox in short-selling:
- If You are wrong, your position balloons and hurts immediately
- If You are right, it helps less and less
So, the whole game is of short selling is about position sizing and risk management:How can positions be sized so that they would contribute but not hurt ?This is probably one of the tallest order in fund management.Between Charybdis and Scylla: Open Vs closed risk dichotomy
People perceive risk as either static, as in constant or completely random.
Well, it is somewhere in between and it depends on how You trade risk in the first place.
It reflects back on the concept of open versus closed risk. Open risk is the tropism of mean reversion strategy. Everything hums fine until the big iceberg. Closed risk means risk is capped.Your view of the world will shape your risk profile. If You run an open risk model then because of its inherent unpredictability You are condemned to run it at low risk ad perpetuitam.If You run a closed risk, then You can accelerate and decelerate within the bounds of your risk tolerance.Accelerator and brakes
This is one of the most profound discoveries I made in 2015. there are two types of people when it comes to sizing a bet: those who take risks and sometimes get hurt along the way and the risk adverse crowd who will consistently take minimal risk.I think this relates to the essence of the question: Can I build a system that preserves capital when strategy does not work but takes risk when it does.I think I can answer this one with good wisdom. Please read this post:The thought behind the math was this: is there a middle ground between pedestrians and F-1 racers ? I think I found the formula. Please read the above post. We have used it and it does wonders, beyond what i theoretically expected in fact:
- When good times roll over, risk per trade is extremely responsive: brings risk to minimum right away.
- Concentration decreases: smaller risk per trade means smaller positions, means lower concentration , more positions, diversification
- But because surface does not change dramatically, position sizes are fairly reasonable. They do not swing from 0.15% to 15%
When the sh*** hits the fan, everything goes into Guantanamo, but it can still trade and thereby reboot itself.
- The skew of the convexity means that every marginal cgains translates into buying power restoration
- That posSizer is the best sleeping pill i know

Better System Trader 2nd Interview:
Andrew Swanscott has one of the best podcasts on trading out there. He has brilliantly interviewed world trading champions, legends such as Van Tharp, Larry Williams, Jerry Parker, Perry Kaufman etc. In each episode, there is a nugget of wisdom. One word of caution though: Better System Trader is more addictive than chocolate.
It was an honour to be interviewed on episode 32.
With the recent “soft patch” in global markets, Andrew decided it was time to catch up and go deeper into topics such as psychology. Markets are stressful on the long side already. On the short side, pressure is something else entirely.
Thank You very much for all the questions and comments on the website. If You have questions You would like to ask on the podcast, please go to the link below:
http://bettersystemtrader.com/ask-laurent-bernut/
Topics covered this time will probably be:
- How to improve your trading edge ? (This is a question from a reader, thank You). A post will follow shortly
- Sherlock Vs the Red Queen: why people fail at short selling ? You will understand the trappings in which people coming from the Long side fall. This topic has never been approached from a statistical perspective.
- The psychology of Stop Loss: did You notice that your desk is cleaner when You can’t close a bad trade ? We all know that cutting losses and riding winners is the key to success. We will go through evolutionary psychology, affective neurosciences. We will teach You how to reframe stop loss and trade like a psychopath
- Jedi trading: if You want to be the iceman on the trading floor and if You want to switch from fight, freeze or flight syndrome to flow state in less than 2 minutes, then practice this technique
- if we have time: why You should not be afraid of this bear market, Einstein and monkeys and the importance of Chuck Norris
@Quora: In trading, how can I stop getting emotional?
Answer by Laurent Bernut: @Quora: In trading, how can I stop getting emotional?
Excellent answer from @Nate Anderson. Viktor Frankl (Man’s search for a meaning) survived both Auschwitz and Dachau. One of his most profound lessons was that: “between stimulus and response, there is a space called freedom”. You cannot control what is happening to You, but You can control your response.The paradox of systematic traders and psychology
Every systematic trader who writes about building trading system devotes a lengthy chapter on psychology. Meanwhile fundamentalist hardly ever talk about psychology. You would think that mechanical traders would care less about psychology and people who rely on their judgement talk more about it.My theory is that systematic traders experienced mentally devastating losses which prompted them to develop systems so as to remove emotions. Along the way, they managed to quantify their systems and realised that after all is said and done: 90% of trading is mental, the other half is good maths.Bottom line: Your emotional hijack means You do not have system yetThe counter-intuitive trick about system development
Most people who develop systems fail to execute. There are two reasons: they focus on the wrong thing and they don’t have faith in their system.Wrong focus: the only soldiers who do not have exit strategy are kamikaze
People focus exclusively on entry and consider exits as an after thought. They have it completely backward. Entry is a choice, exit is a necessity. Emotions kick in once a position is in the portfolio, not before.Real life example: Long IAU strike 11 April 2016 options at 0.20 on entry date. Actually, I had my eye on the 12 strike but a fat fingered Viognier Zibibbo called Abraxas (how can You not surrender to that deadly combination ?) got in the way of trading. I felt bad for a couple of days and then moved on, c’est la vie.Now, let’s say i would have bought in the chrematocoulrophony (financial jesters) and sold the same option on that day. Current value is 1.20 with 2 months time value left. That is -500%. This thing would have drilled a hole in my portfolio through the center of the earth and pop out somewhere in Antarctica. It would have drilled a hole in my brain. I would feel trapped without a way out.Bottom line: system development starts with the exit in mind.Corollary: Peace of mind
Before: no clear exit strategy. I used to read every single news, check prices 2-3-5-10 times a day. I was always torn between running positions a bit longer (greed) and taking money off the table (fear).After: exit strategy for every contingency: It brought immense peace of mind. There were three booby traps: stop loss, profit target and on the time axis trend reversal. I knew that unless an exit condition was tripped, positions would run their course. I had harnessed volatility. I checked price once a day, the rest of the time, I was one of the heaviest users of YouTube on earth. This lead to surreal conversations with my boss:– “What ! Are You watching another Shaolin flick ?”, he laughed– “Why ? You are not ?”, I replied vaguely outraged by his lack of cultural curiosity “Time for some off-site (code word for plundering the Roppongi Enoteca wine shop) ?”– “it’s only 4:00 pm”, he said looking for a feeble excuse– “Yeah, I know late start, let’s get into position for the happy hour”, with high conviction for the daySystematic execution and pregnancy
Developing a system that works is the hard part. And then executing it day in day out is the hard part. This is where a lot of guys trip in the carpet. They spend considerable time developing a strategy that they run until it stops working. Then, it is back to the drawing board, tweaking endlessly, waterboarding it until it confesses. Two reasons:
- Complexity is a form of laziness: I have seen a lot of systematic strategies. The most fragile ones are always the most complex ones. Optimisation is the poor brain solution
- Faith: We trade our beliefs. The best example is Markowitz, the father of the half century old modern portfolio theory (MPT). At the end of his career, a journalist asked him the composition of his portfolio. The inventor of the efficient frontier candidly replied: 50% stocks, 50% bonds. I rest my case
Bottom line: systematic trading is like pregnancy. Either You are pregnant, either You are not. Sorry, but You can’t be un-pregnant on ladies night.Trading is 90% mental, the other half is good math
Mindfulness:
Ray Dalio meditates, twice a day. I rest my case. I meditate every day, sometimes twice during rough markets. Before trading, I seat in silence 2 to 5 minutes until presence.Check Rande Howell at Trader State of Mind. His work is unique and transformative. He works on the Pearson Marr or Jungian archetypes. I cannot recommend his work highly enough.I would highly recommend the App called Calm.com. It is reasonably priced and has excellent guided meditation.Journal your journey:
Journal your journey through the markets. Journal your emotions, when You are making money and when You aren’t. Pay particular attention to your fears when losing money.I am working on a format that could be useful and meaningful using Google sheets and Evernote. There are some elements of Nathaniel Branden’s stem sentence completion exercise. Mr Branden is famous for his work on self-esteem and deep belief elicitation. There are also elements of Byron Katie’s work. Finally, it is brought together in a quantitative format using Google Sheets.Trade with fear
Some charlatans recommend to trade without fear. That is not how the brain works, at all. Tell the antelope that a lion is just a confused cat. Fear is a signal. Fear is an evolutionary mechanism that has kept You alive to this day. Ignore it, it grows and soon enough it infiltrates your trading, it cripples your action.Fear exists in the shadow. Name it, face it, and then physically walk through it. This is why it important to journal your experience.Fear is vastly underrated. It keeps You sharp. Size your positions as though You expected them to fail.Visualisation
Athletes train to visualize their performance. There are clinical studies that show that athletes who visualize their performance have more muscle mass than those who don’t. Surprisingly enough, those who simply visualise without physical effort have higher muscle density than those who neither train nor visualise.
Visualisation does not mean seeing oneself on the podium with a gold medal, laughing under the cameras. That is wishful thinking. Visualisation is rehearsing procedures to overcome obstacles, feeling fear arousal and bringing calm response. It is about setting anchors that will trigger neuro-physiological responses.
At elite level, athletes are in similar physical shape. The difference that makes the difference is mental preparation. Best example is Conor Mc Gregor versus Chad Mendes. He won the fight mentally before he won it physically. He was on the ground, pummeled by some severe elbows to the head. Meanwhile, he was laughing: “is that all You got ?”
THE POWER OF CHECKLISTS
Airplane pilots have checklists. Firefighters have checklists. Surgeons have checklists (read Atul Gawande’s “Checklist manifesto”). Bottom line: these are highly skilled, highly trained professionals who have responsibility for human lives. They swear by checklists.Meanwhile, finance people believe it is beneath them. Investing is supposedly an art. Checklists free up some precious bandwidth that can be used for thinking. In this ultra competitive sport called trading, every extra bit of mental bandwidth spared is a competitive advantage over emotional traders.Great investors are not smarter, they have smarter habits. Break all your tasks in small specific checklists.Example: my short sell checklist
- Check risk per trade and lots: if position small (i-e too volatile), then reject
- Check exposures & balances: if trade exceed risk, then reject
- Check borrow cost and availability: if expensive, then reject
- Set Stop Loss on platform GTC
- Sell Shares at Limit validity 1 day
- Take break, do something else: cool down and refresh (2-5 mn)
- Verify one last time and send
My entire workflow is broken down into small checklists: Buy to Cover, Buy Long, Sell Long, trade reconciliations, trading signals, portfolio management system update, etc. This helps a lot during stressful times.Conclusion
When we are on the bus in a new city, we check every stop, every building. We are afraid of missing our stop. Before getting on the bus, our stress hormones are mildly activated. Once in, stress hormones go up. Bottom line, exit matters. Think about them before entry
Success is habit. Unfortunately, so is failure. They have the best habits.
Trading is mental: profits are a side effect of inner alignment between deep seated beliefs all the way to daily routines.
