  • The Time Value of Time

    Einstein_1979_USSR_StampIn many senses time is relative. 

    You don't have to be a rocket scientist to understand this quote from Einstein.

    "When you are courting a nice girl, an hour seems like a second.  When you sit on a red-hot cinder, a second seems like an hour.  That's relativity."

    It is about more than perception.  Here is something that highlights the relative value of time.

     

    The Value Of Time:

    • To understand the value of a year, talk to a student who has failed an important exam.
    • To understand the value of a month, talk to a mother who has given birth to a baby a month prematurely.
    • To understand the value of a week, talk to the publisher of a weekly newspaper.
    • To understand the value of an hour, talk to a couple in love who are separated and want only to be together again.
    • To understand the value of a minute, talk to someone who has just missed their train or plane flight.
    • To understand the value of a second, talk to someone who has lost a loved one in an accident.
    • And to understand the value of a millisecond, talk to someone who won the silver medal at the Olympic Games.

    Time waits for no one.  So it is important to remember to make the best use of the time you have.

     

    That Doesn't Mean Time Is Scarce Or Has To Be A Constraint:

    090614 time Time is often thought of as a constraint or a scarce resource. There are lots of phrases that highlight this type of thinking.  For example: I don't have enough time; I'm running late; I'm up against a deadline; There are only 24-hours in a day; or, I’m going as fast as I can. As you might guess, that list goes on further.  Yet, time does not have to be that way … it can be a tool instead.

    So, I started to think about how I used time.  Was I making the most of it … or taking it for granted?  It didn’t take much introspection to notice a few of the ruts I fell into.  I'm going to talk about one of them, here, because a small shift had a massive impact.  The thing we changed was our pace.

     

    A Change of Pace:

    When I jog, the beginning and the end are the hardest for me. Yet, after I find that initial pace and I settle into a comfortable rhythm, the majority of the run is relatively painless. My mind and body switch to an nearly automatic mode and I have time to think about many things.

    Work is similar in many respects. Once a team gets in a rhythm, work and progress are somewhat automatic. Breaking inertia is a challenge; but people recognize that it's a challenge. The more insidious problem is to fail to recognize that the work rhythm that's comfortable, and which produces progress, is still a rut. It doesn't stretch and challenge the team to strive for more. Yet, this stretching is what drives innovation. It's the thought we haven't had yet … and a new perspective that changes everything.

    Changing your pace can be an incredible catalyst to make that happen for you. For example, imagine that we put together a new portfolio in two weeks, on a wholly new tech platform, with new markets, and using new techniques. Then we tested, re-balanced and rebuilt that portfolio in one week. What we did, or the time in which we did it, wasn’t important. The important part is that it caused the team to work at a radically different pace than before. It was a sprint.

    Moreover, this sprint caused us to re-think what we do, and more importantly, how we do it.  Many of the innovations and new distinctions that we discovered through this process will work their way into other areas of our work,  and will act as a catalyst for us to re-evaluate the way we do things.

     

    A Challenge For You:

    I challenge you to consciously change the pace of something that you are already comfortable doing a certain way. The pace can be faster, or the pace can be slower … it doesn't matter.  Then notice what comes up for you, and what new opportunities and possibilities you discover.

    Time is a valuable resource. Take this opportunity to re-examine how you can best view and use time to make the most of it.

  • A Statistically Significant Edge

    Last week we discussed that just because a trading system is making money doesn't prove it has an edge.  It means you have both the chance that the system has an edge – and also that it may just be lucky.

    One of our advisors wrote back to see if they understood that approach.

     

    The odds of flipping a coin and getting heads 25 times in a row is roughly 1-in-33 million. So if we have 33 million flippers and 100 get 25 heads in a row, statistically that is very improbable.  We can deduce that group of 100 is a combination of some lucky flippers, but also that some have a "flipping edge."  We may not be able to say which is which, but as a group our 100 will still consistently provide an edge in future flip-offs.

     

    Well, that is correct.  In fact, if we were developing coin-flipping agents that would be as far as we would be able to go.  However, we are in luck because our problem has an extra dimension, which makes it possible to filter-out some of the "lucky" Bots from our trading systems.

     

    Determining Which are the Best Systems.

     

    There are several ways to determine whether a trading system has a persistent edge.  For example, we can look at the market returns during the trading period and compare and contrast that with our trading results.

    This is significant because many systems have either a long or short bias.  That means even if a system does not have an edge, it would be more likely to turn a profit when its bias is in alignment with the market. 

    We try to correct that bias using some math and statistical magic, in order to determine whether the system has a predictive edge.

     

    It Is a Lot Simpler Than It Sounds.090523 Roulette Wheel

     
    Imagine a system that picks trades based on a roulette spin.  Instead of numbers or colors, the wheel is filled with "Go Long" and "Go Short" selections.  As long as the choices are balanced, the system is random.  But what if the roulette wheel had more opportunities for "long" selections than "short" selections?

    This random system would appear to be "in-phase" whenever the market is in an uptrend.  But does it have an edge? 

    One Way To Calculate Whether You Have An Edge.
     

    Let's say that you test a particular trading system on hourly bars of the S&P 500 Index from January 2000 until today. 

     

    1. The first thing you need is the total net profit of the system for all its trades.  
    2. The second thing you need to calculate is the percent of time it spent long and short during the test period.
    3. Third, you need to generate a reasonably large population of completely random entries and exits with the same percentage of long/short time as your back-tested results (this step can be done many times to create a range of results). 
    4. Fourth, use statistical inference to calculate the average profit of these purely random entry tests for that same test period. 
    5. Finally, subtract that amount from the total back-tested net profit from the first step.

     

    According to the law of large numbers, in the case of the "roulette" system illustrated above, correcting for bias this way, the P&L of random systems would end up close to zero … while systems with real predictive power would be left with significant residual profits after the bias correction.

    While, the math isn't difficult … the process is still challenging because it takes significant resources to crunch that many numbers for hundreds of thousands of Bots. 

    The good thing about RAM, CPU cycles and disk space is that they keep getting cheaper and more powerful.

  • Switching Strategies

    We said goodbye to Duke today.  He was our faithful companion for 13 years.  He will be missed.

     

    161204 Saying Goodbye to Duke

     

    We did everything we could, until we couldn't … Then we switched to a different strategy.

     

  • What My Dogs Can Teach Us About Markets

    Yellow Lab Laying Down 200p  Some dogs run fast; other dogs do tricks … my 100 pound lab, Duke's best talent is his ability to remain immobile in almost any situation (some call it "laziness" … I prefer "calm" or "even-tempered").

    At the other end of the spectrum is Boo, our 20 pound mix between a Beagle and a Boston terrier. Let's just say that he has higher metabolism than Duke. 

    When Boo hears a noise, he lets out an involuntary, barely audible, sound.  His body becomes rigid and his head cocks.  He becomes alert and carefully tunes his ears to their most sensitive setting, seeking any information that will help identify the "danger." And now he's waiting for the next intrusion.

    Usually there are no other disturbances to follow, and the noise is cataloged and soon forgotten. His alertness level slowly subsides over the next 10-15 minutes or so.  He'll go back to napping, a little more fitfully this time … and just a little bit on edge.

    Things get a little more interesting when another noise surfaces shortly after the first one.  What could once be dismissed now must be treated as a threat – and just to be safe, a threat of the highest order.  Now the appropriate response is a series of barks, nervous glances, pacing, rushing off in the direction of the noise to investigate, and a barrage of barks meant to sound more menacing than the source of the noise.  Who or what is it? How much harm can they cause? How grave is the threat?

    Boo Alert Duke is a different story.  Nothing upsets Duke more than Boo.  The same noise that prompted Boo to become alert does nothing to Duke.  However the first time that Boo makes noise, that makes Duke alert. And the second time Boo makes noise, Duke starts vocalizing, and the third time, well now both of them start yapping and when they both start yapping, then other dogs in the neighborhood start yapping.

    I realized that the same thing happens in the market with people.

    In the market, it is the second noise – and subsequent noises – that creates the equivalent of the Homeland Security "Red Alert." Once an elevated level of alertness has been established, it takes a long period of relative calm for it to subside.  And when on "Red Alert" … any additional noises (for example, the responses of the other market participants) – big or small – will highlight, magnify and further validate the issue.

    But, like in the story "The Boy Who Cried Wolf," even legitimate threats are ignored after too many false alarms (or prolonged periods of constant alert).  So, bad news about the economy isn't as likely to get people excited after the past few weeks.

  • Feeling Thankful is a Weak Substitute for Being Thankful

    Thanksgiving is a holiday where we're encouraged to feel thankful for all the bounties in our life – and to appreciate those around us. 

    I enjoyed spending time with my kids, watching the Cowboys win, and eating too much.

      

    Fullsizeoutput_40de

     

    That's a great start; but, feeling thankful is different that being thankful.

    Think of it as the difference between passive voice and active living.  

    It reminds me of an idea called "Tikkun Olam" (or – healing the world).

    Even if you're not Jewish, I think we can all agree the world needs a little of that. 

    For example, instead of just feeling thankful, what could you do to make the life of someone around you better?  Likewise, how can you let others know that you're thankful for them?

    Transformational change is often easier than incremental change (because you don't have to drag the past forward).

    So, what can you do that would trigger 10X results?   Will you?

  • Donald Trump Is the President-Elect

    The election was very interesting to me.   

    While Hillary Clinton deftly followed the wisdom of Napoleon: “Never interfere with the enemy when he is in the process of destroying himself.”   It didn't work.

    I believe Trump’s success is a direct result of a broader collective dissatisfaction and negative mood trend in America.

    As unlikely as the outcome was, socioeconomics explains it well.

    Socionomics is the study of how social mood motivates social actions. It studies how waves of social mood regulate changes in social behavior, including changes in the economypolitical preferencesfinancial markets and popular culture.

    Last year, if you told me 2016 would be the year that: the Cubs would win the world series, a reality TV show host would be president, and Britain would leave the EU, I'd have assumed you were on drugs.

    Even three months ago I would have been surprised. 

    Last week, MogIA, an AI, predicted that Donald Trump would win, making it 4 for 4.  If you had been tracking the polls, that would have felt ridiculous, but computers can be more objective than you or me. 

    Trump's campaign was a polarizing affair, with massive backlash from liberals, and a mainstream media which almost completely missed the momentum Trump had.

    There're massive parallels between the way the media reported this campaign, and what happened with Brexit.  The media echo chamber was pro-Clinton and ended up ignoring the feelings of a large group of voters.  In Britain it was the elderly  …  in America, it was working-class white people.

    Trump won swing states like Pennsylvania and Michigan in large part due to those voters feeling ignored and attacked by Clinton. Coal and Gas are their livelihoods, and efforts towards clean renewable energy could leave them jobless.

    Think of all the moving pieces that had to align for Trump to get this far. Look at the candidates in the Republican primary, look at what happened with the Democratic primary, and look at voter turnout:

    If "Did Not Vote" was a candidate, they would have won by a landslide. 

    But, people did vote – and the result is change.

    So, what do you think the effect will be on America and our stock market, long term under Trump?

    Leading into the final days of the election, you can see a steep drop in markets. Uncertainty often has that effect on a market, but since Trump's election, there's been a rebound.

    In fact, the Dow Jones Industrial Average was able to set an all-time high.

    As well, Putin has expressed interest in restoring ties with the U.S.   It will be interesting to see the effects of this on the geopolitical environment. 

    If there's anything to learn from this experience, it's that trying to time the market is dangerous, and that ignoring dissidents makes you out of touch and vulnerable. 

    On a lighter note, here's the President-elect, Donald Trump, wrestling at Wrestlemania 23. He's a regular Ronald Reagan.

     

     

     

  • Clown Hysteria: 2016 in a Nutshell

    This summer, South Carolinians started seeing menacing clowns in the woods.

    As a response to clown hysteria,Target pulled clown masks from shelves , McDonalds scaled down use of Ronald McDonald, and people everywhere have been in a fervor.

    Not everyone has been affected negatively though … Surprisingly (to me), Pornhub has seen a massive increase in clown related searches.

    There you have it … hard data.

    2016 continues to surprise … Celebrities dying, phones exploding, the election, and this.

    It will be interesting to see how 2016 ends, and what the future brings.

    The world changes, but human nature remains relatively constant.
