How Our Physical Health Impacts Our Trading Psychology

Let's take a look at how the state of our bodies impacts our health and well-being and ultimately the mindsets we bring to trading.

Recent research suggests that a sedentary lifestyle--one without exercise--is more harmful to our health than smoking, diabetes, or high blood pressure.  The lack of aerobic fitness is a larger risk factor for mortality than having many medical conditions that we regard as necessary to treat.

*  Poor posture, such as sitting hunched over a screen for many hours per day, has been implicated in low blood oxygen levels.  Low blood oxygen levels are associated with higher stress levels and greater fatigue, both of which can negatively impact our executive brain functions and ultimately our performance.

Fascinating studies placing people in high altitudes (and thereby reducing their blood oxygen levels) find that low blood oxygen is responsible for declines in mood and worse cognitive performance.  Poor aerobic fitness interferes with our optimal processing of information.

Research finds that increased exercise is associated with lower rates of depression and greater levels of happiness.  Exercise also improves our sleep quality, which in turn is associated with higher levels of well-being and focus/concentration.

There is yet another way in which physical exercise can help our trading.  By training ourselves to tackle challenges, day after day, we build a mindset that encourages the tackling of challenges in other areas of life.  Quite simply, developing ourselves physically can be a powerful pathway toward developing our performance--in markets and in our personal lives.

The Power Measure: How Is Volume Moving Price?

In the most recent Forbes article, I highlighted the importance of monitoring the amount of movement we get per unit of market volume.  When we look at normal bar charts, we see price as a function of time, with volume on the X-axis.  A large bar tends to be one in which we see increased volume (increased participation at that point in time), moving the market more than usual.

A different way of viewing market behavior is to look at volume bars (price where each bar represents an amount of volume traded) and see if bar size (volatility) is expanding on the upside or downside.  What this is telling us is not just how much volume is coming into the market, but how much each unit of volume is actually moving price.  When we see bigger bars coming in on market upmoves than downmoves, we can actually visualize where the market is finding its greatest ease of movement.

(This is a great example of the importance of creativity in trading.  Looking at price-volume-time through different lenses enables us to see fresh relationships that can illuminate what is actually going on in the market.  Looking at the same charts as everyone else is a great way of seeing the same things as everyone and becoming part of the proverbial herd.)

Above we see the full day's trade in the ES futures for 10/16/2018.  It's a great day to study, given the major turnaround in the overnight session and trend day during NY hours.  The blue line is the ES futures, with each bar representing a small unit of trading volume.  The red line is a running correlation of the size of the bars and the directional movement (open to close) of the bars.  Hence, when we get more upside movement per unit of trading volume, the correlation goes positive and vice versa.  

Shifts in this "power measure" tell us that volume is moving price more easily in one direction than another--a worthwhile heads up, though not a precise timing measure.  Notice, for example, how the correlation shifted positive and stayed positive during the period of the market's big turnaround.  Notice how subsequent moves lower in the correlation occurred at successively higher price lows--a great indication of the underlying strength of the market.

This is a relationship relevant to multiple time frames.  The illustration above, with over 500 bars per day, is clearly relevant to active day traders.  I maintain the measure for bars with much larger volume to examine multiday patterns.  The value of such measures is not as crystal balls, but as multiple lenses through which we can understand the dynamics between buyers and sellers.  There are many other such lenses, such as the shifts in distribution of upticks and downticks across all listed stocks.  Many trading problems occur, not because of emotional disruption, but because of cognitive poverty:  an absence of perspectives that yield fresh, valid insights.

How To Prepare For Challenging Trading

If Noah had waited for the storms and floods, it would have been too late to gather the animals and build the ark.  Our role as traders is to prepare for possible adverse outcomes so that we can ensure our survival should one of those materialize.

How can we prepare properly?

In the recent Forbes article on how to navigate these volatile markets, I make the point that a close examination of similar historical periods can help us anticipate a variety of scenarios: both ones of risk and ones of opportunity.  It's not that the immediate future will replicate any of the past price paths in similar circumstances.  It's that the past price paths can tell us what is possible--and maybe even what is likely--going forward.

So let's take a specific example.  I recently noted that we had made a multi-standard deviation move to the downside--over five standard deviations, to be precise.  In similar situations going back to 1993, we were up 11 times, down 4 over the next five trading sessions.  Of the four down instances, all were lower by more than 2%.  Of the eleven up instances, six were higher by more than 3%.  Volatility was the norm and bounces were common.

Psychologically that alerted me that, even though I thought we could see further downside, I had to be prepared for short squeezes.  In fact, those have been more common in the past than not.  The past instances also alerted me to the likelihood of further volatility, which led me to temper my position size.  When we traded weak in morning hours, I took an initial short position, saw it go my way modestly, and then bounce higher.  The quality of the bounce made me take notice, as it demonstrated a shift in the amount of movement per unit of volume--something I describe in the Forbes post.  I quickly covered my short position for a small loss and avoided a larger drawdown.

Knowledge of the past prepared me for possible future outcomes.  It helped me stay open minded--and that helped me manage risk.  In trading as in sports, preparation primes us for action and that builds our mindset.

Lessons We Can Take Away From Broadly Oversold Markets

And the trick, of course, is getting cut the right way.  An uncut diamond isn't worth much, and a diamond cut the wrong way is too flawed to be worth anything.  When we take losses the right way and learn from those, that's when we develop the facets that give us value as traders.

One of the bad cuts I see people taking in the recent equity markets is failing to adapt to new, volatile market conditions.  Buy the dip at VIX of 12 is quite different from the same strategy at VIX of 24.  When a market becomes more volatile, we trade more volume per unit of time.  Moves that might have unfolded in hours now occur in a few minutes.  That has relevance for how you size positions and how much heat you can take on ideas that ultimately work out.

I looked at the overbought/oversold statistics from Index Indicators and found something outstanding.  Fewer than 5% of stocks in the SPX are trading above their 3, 5, 10, and 20-day moving averages.  In other words, not only are we quite oversold; we are very broadly oversold.  Essentially everything has gone down.

So what has happened historically after such broadly oversold occasions?

Since 2006, when I began my database, we have only had 15 other such days.  That means that broadly oversold markets only occur less than half a percent of the time.  As we saw in the last post, this means that the current market conditions are historically rare.  Below we can see the dates of occurrence in chronological order:


9/29/2008
10/7/2008
10/9/2008
11/20/2008
5/6/2010
5/7/2010
5/20/2010
8/2/2011
8/4/2011
8/8/2011
10/3/2011
11/23/2011
8/24/2015
8/25/2015
2/8/2018

We can see right away two things:


1)  These rare occasions can "clump".  When we see one, it's not unusual for others to follow.  This is also something we saw in the last post.  A very oversold market can stay oversold for a period and indeed become more weak.

2)  These occasions have occurred during markets we have recognized as meaningful corrective periods or as bear markets.  These occasions have also been accompanied by significant volatility.  The median VIX for the 15 occurrences has been almost 41.  The median VIX for the rest of the sample is a little over 16.

And what have been the forward paths for these broadly oversold markets?

Bounces have been the norm, but it's not always a one-way path.  The next day has been 9 up, 6 down.  Two days later has been 12 up, 3 down.  Five days later has been 12 up, 3 down.  That being said, ten trading days later we see 8 up, 7 down.  Ten of the 15 occasions have posted a lower daily close within a ten trading day period.  Two-sided markets over the next two weeks are not unusual.

Forward volatility is expectable.  Thirteen of the 15 occasions moved more than 2% from close to close over the next two trading sessions.  Nine of the occasions moved more than 4% up or down over a next five-day period.  Very large moves are not uncommon.  During 2008, we saw near-term closes up 9% or more and down 9% or more.  After the 2011 occurrences, we saw moves up and down exceeding 5%.

There has been opportunity longer-term.  The longer-term investor recognizes that broadly oversold markets are taking down high quality, growth companies along with less stellar firms.  This can create unusual value for individual stocks and also for the market. With the exception of the 2008 occurrences--a protracted bear market--we were meaningfully higher in SPX one year after the broad selling periods.  If we believe this to not be a recessionary period with major economic dislocations, the drop can be a great opportunity to buy stocks for longer-term holding periods.  

So it's back to the theme of getting cut the right ways.  When market participants puke, it's common to see favorable forward returns, but not without volatility and retracements.  Shorter-term traders can take each day as it comes, knowing there will be meaningful movement to capture.  Longer-term investors can identify stocks worth snapping up at bargains, but also create market hedges (and size appropriately) to weather the forward volatility.

Knowing historical patterns is a great way to prepare oneself for forward price paths.

What Happens After A Huge Down Day?

Well, I had a record number of phone calls and emails yesterday and you can guess why.  The yellow caution signal that we discussed on September 24th proved to be a worthy alert.  Yesterday the stock market dropped around 4% on very elevated volume, closing at its lows for the day.  I went back to 1993 in SPY and learned a few interesting things:

1)  This daily move down was more than 5 standard deviations from the average move, using the last 100 trading days as a reference point.

2)  Downward moves of over 4 standard deviations have occurred only 15 times since 1993.  So, in over 6000 days of data, this has occurred less than .25% of the time.  It's a truly rare occurrence.

3)  Occasions when the 4+ standard deviation moves have occurred include the following dates.  Note the prominence of bear market periods and significant market corrections.  Note also that one such occurrence does not prevent the possibility of another occurrence shortly after, as in 2015 and 2018.  We also saw multiple large down days in 1994, 1998, and 2008, though not at 4+ SD.  In other words, we cannot count on "one and done"; such outlier events tend to cluster:


2/5/2018
2/27/2007
8/8/2011
10/27/1997
2/2/2018
8/31/1998
2/8/2018
8/24/2015
8/4/2011
9/29/2008
2/4/1994
6/24/2016
9/17/2001
3/8/1996
8/21/2015

4)  One day, five days, and 20 days later, the market was up 11 times and down 4.  Over the course of the next 20 days, the market made a lower close on 9 of the 15 occasions.  On the occasions where the market made lower closes five days later, all four declines were in excess of 2%.  On 10 of the 15 occasions, the market moved more than 2% over the next 10 trading days.  Volatility continued to be the norm.

So what can we take away?

A)  We are in a historically rare event.  Casually applying normal rules and "setups" to the current situation can be hazardous to your wealth.

B)  A bounce from the big down day is the most common scenario.  Twelve of the 15 occurrences posted a higher close within the next five trading days.  That being said, the majority of instances also posted lower closes over a 20 day horizon.  V bottoms have been the exception.

C)  Volatility continues over the next 20-day period, with moves greater than 2%--up or down--occurring in all but two of the instances over the next ten trading days.  

D)  The presence of one rare drop does not preclude others from occurring and indeed there is evidence of clustering during bear periods.  Failure to sustain rallies after the big drop should be viewed with caution.  Significant additional large drops occurred in 2008, 2015, and 2018, for example.

Psychologically my takeaway is that investors should have a long-term view of opportunity--on a long time frame these were good buying opportunities--but on a short time frame a degree of hedging is prudent.  Shorter-term traders should view a failure to sustain bounces as possible occasions for further large declines.  Open-mindedness is key.

Viewing and Reviewing Your Trading

An excellent, successful SMB/Kershner trader I've known for years recently made a Q&A video where he shares valuable lessons from his development.  One of the important points he makes is the crucial role that review plays in honing trading skills.  I can vouch for the fact that he reviews his trading religiously every day and shares those reviews with a variety of colleagues.  He learns from the reviews and role models trader development for others: a great example of each one teach one.

As Les Brown notes above, a double review serves an important focusing purpose.  The first review occurs at the start of trading where you examine how your markets or stocks are setting up and you figure out--specifically--how you will apply your trading goals to the current market conditions.  For example, one of the things I'm working on in my trading is developing better estimates of how far moves can extend and adapting my scaling out of profitable positions to take better advantage of markets that expand their volume and volatility during the day.  My premarket review examines relative volume in real time and lays out a tentative plan for sizing and scaling.

Note that the idea here is not to simply review an abstract goal, but instead to actively apply that goal to upcoming performance.  A goal not actively applied is merely a good intention.  It is planning that gives goals their life.

At the end of the trading day comes the second review.  We examine how well we actually acted upon our plans and goals.  If I made progress on the goal, I will note how I did that in real time and will bring that positive learning lesson forward to the next day.  If I failed to move forward on the goal, I will dissect what went wrong.  Did I read the market incorrectly or fail to properly update my views on volume and volatility?  Did I become distracted and lose sight of my goal altogether?  Did I become too focused on sizing up that I missed the fact that the opportunity set was waning?  What I could have done better frames the goals for the next trading session, which will become plans in the morning review.

Every day.  

That is how learning compounds and develops into expertise.  That is what improves our odds of long-term success.  

Yet a further refinement is to conduct separate reviews of the various facets of trading:

*  How well did you develop sound ideas to trade?
*  How well did you enter positions and achieve favorable reward relative to risk?
*  How well did you scale into and/or out of positions to optimize profitability and manage risk?
*  How well did you manage yourself during the trade--and throughout the day--to sustain optimal focus and keep yourself in a peak performing state?

Just as a tennis player will work on different aspects of her or his game (the serve; backhand; net game; etc.), we view and review different facets of trading to ensure that our development extends to everything we do.  In a gym, you'll work different parts of your body--upper, midsection, lower--and you'll work on aerobic conditioning as well as strength.  So, too, do we work on different facets of what we do as a trader.

That is how developing ourselves as traders inevitably intersects with our personal development.  In refining our skills, we refine ourselves.

Where Does Market Edge Come From?

Above is a screenshot from my trading station, capturing roughly the last eight days of trading in the ES futures, using hourly data.  Volume is on the X axis.  Below volume is a two-period RSI that is a very short term measure of overbought/oversold.  Above volume is a linear regression line (red) with bands of one standard deviation (blue) above and below.

The chart nice illustrates how markets are a joint function of linear trend (the regression line), with one or more cyclical functions overlaid (the movements from upper to lower bands; the movements between short-term overbought and oversold).  Notice how often the market will take out a prior low or a previous high, only to cycle back the other way.  It's a good illustration of how traders who think primarily in terms of breakouts, momentum, and directional trends get "chopped up" by the market's cyclicality.

Much of the frustration from trading comes from the imposition of linear thinking on markets that have significant cyclical drivers.  During stable market periods, we can "solve" for dominant cycles and then use movement above and below the bands to identify when stability is breaking down and we're entering a different cyclical or directional regime.  The idea is *not* to trade according to your personality.  The idea is to capture the linear and cyclical components of markets and trade the market's personality.

If you get the basic idea of interacting trends and cycles, you can see why the following has very limited edge:

*  Chart patterns taken out of context;
*  Oscillator readings taken out of context;
*  News "catalysts" taken out of context;
*  Breakouts taken out of context;
*  Wave counts or Fibonacci patterns imposed on markets;
*  Releases of fundamental data

So what does have edge?  In my experience, it comes from identifying when 1) the herd (which thinks one-dimensionally in terms of linear/directional movement) gets trapped at cycle extremes and 2) when shorter-term "mean reversion" traders get trapped by the momentum components of longer-term cycles and trends.

What has edge in the quant world is the dynamic modeling and re-modeling of shifting cyclical and directional components of markets, rather than static, curve-fit models based on lookback periods.  This is a big reason why funds that make use of true machine learning are the top performers in recent years and why many funds underperform their benchmarks.

The Real Way To Learn Trading

In a recent article, I ask the question of whether individual traders can succeed in financial markets and take a look at actual research on the percentage of traders who sustain profitability.  I also examine a number of successful training efforts and what they are doing to increase the odds of trading success.

What emerges from this exploration is an insight:

The real way to learn trading is not so different from the real way to learn to be a doctor:  see one, do one, teach one.  

Medical students begin their clinical education by shadowing experienced doctors and seeing first hand what they do, hearing why they're doing it, and observing how they do it.  Learning first occurs at the bedside or in the examination room.

The next phase of learning for the medical student is doing some of the work with patients themselves, while under close observation and supervision.  This might begin with taking histories and conducting physical exams and progress to assisting in simple procedures, such as removing a skin growth.  All of this learning occurs within a team, with frequent evaluation and feedback to build skills.

The more advanced phase of learning occurs when the medical student becomes a resident physician and participates in the teaching of new students.  We learn by observing and doing, but it is teaching others that cements our knowledge and extends our experience.

As this analogy points out, the real way to learn trading is to not learn solo.  Basketball and football players always learn from coaches and teammates; artists, musicians, and chess masters always train with mentors.  So few succeed in financial markets because:  a) they begin with limited capital and cannot sustain a living from normal, expectable returns; and b) they lack structured learning processes and resources.

The old model of trader education emphasized didactic seminars/webinars; the newer model embraces mentoring and interactive learning in teams at hedge funds and proprietary trading firms and via online communities.  It is in these venues that traders have a real opportunity to see one, do one, teach one.  And it is in these venues that we can see enhanced odds of trading success.

Webinar To Improve Your Trading Performance

I'm pleased to announce a free webinar hosted by Journalytix on the topic of "Taking Your Journals--And Your Performance--To The Next Level".  The session will be held at 4:30 PM EST on Monday, October 1st.  I like what the Journalytix folks have done in creating a next-generation journaling tool.  One app connects your daily journal with your key trading statistics, news feed, and event calendar--and it all updates in real time via your data feed.

The Monday presentation will focus on how you can use journals and trading stats to more clearly define where you do and don't have edges in your trading.  One observation I've made with developing traders is that they will trade multiple patterns/setups and will assume that these have an edge.  When they break down their profitability as a function of the strategy traded, however, it often is the case that most of their profits are coming from one or two key types of trading.

By using trading stats as an objective performance measure and, from the numbers, defining goals to work on each day/week/month, traders can greatly accelerate their progress.  With traders I observe first-hand, for instance, at SMB, I notice distinct improvement among those who religiously keep their stats and generate monthly goals.  We really can take control of the pace of our trading progress.

I look forward to sharing best journaling practices with you and responding to your questions on Monday.  Thanks!
