What Is The Fishbone Investment Model?


One recurring theme in our investment methodology is that stock prices are a reflection of fundamental intrinsic value and perceived investor emotion / sentiment towards the stock market. This puts an important weighting on behavioral market variables and in our opinion negates the concept of the Efficient Market Hypothesis (EMH).

My background as a Chartered Financial Analyst has focused almost exclusively on the fundamental drivers of a company and its stock price. The basis of almost all of our investment ideas are rooted in the analysis of corporate financials and company variables first and then expecting the stock to trade based on the underlying corporation. Fundamental analysis is sound and proven and is a staple in our investment decision making process. This type pf analysis helps us establish which investments may be a great fundamental endeavor but tells us very little about the near-term movement of the actual stock itself.

Early on in my career I had been thwarted at times when a seemingly fundamentally sound company didn’t have its stock cooperate in my investment thesis. As my studies in behavioral finance expanded I started to realize that fundamental analysis has its uses in pinpointing an appropriate investment but did little to indicate the appropriate entry point to start purchasing the stock. In short, fundamental analysis assisted in establishing which investments to make but did little to provide insight on when to make the investment. 

As my education and research expanded into the field of behavioral finance, it was only then did I realize the importance of investor emotion and sentiment in the investment decision making process. It seemed to contradict many years of teachings that surrounded the EMH but the more I learned about the phycology of investing, the more enlightened I became. It allowed me the opportunity to self-reflect on the shortcomings of focusing exclusively on one field of investment theory. Understand that the use of fundamental analysis still carries a strong influence on the decision making process, but through the works of people like Amos Tversky and Daniel Kahneman it allowed me to grasp a more rounded and holistic approach to portfolio management.

What is Fishbone?

The fishbone model was designed to assist in adding a timing mechanism to the portfolio. The portfolio itself has core holdings that have been introduced based on the fundamental merits of that particular underlying investment vehicle. The Fishbone program allows us to “trade around” our core position to insert portfolio protection when the market trends are unfavorable to the portfolio. It attempts to capture the investor emotion / sentiment part of the equation that if left unchecked can damage even the highest quality fundamentally derived portfolio. The name Fishbone may appear odd but it was given its name by the way it functioned.

While conceptualizing and back-testing the theory, it initially started on a large white board and was a series of “if-then” functions. If the first variable was met, then the model would progress in a straight line to the next variable. If it failed the first variable it would splinter off into a non-investment criteria.

 
 
 
 
 

We completed a twenty year back-test and found that using the Fishbone model indeed offered statistically significant results that indeed enhanced the return of our core fundamentally driven portfolios.

Fishbone Assumptions

Like many other of our quantitative investment theories this one comes with a set of assumptions that we need to believe hold true in the capital markets today.

Assumption #1 – Mean Reversion: What is irrational will soon become rational. Bubbles do exists. There will be times when an investment is profoundly over or under valued based on fundamental analysis. This can create outlier opportunities. The concept of mean reversion is of the utmost importance in our investment methodology. The entire market is a mean-reverting mechanism and finding those outlier opportunities offers the greatest potential for capital appreciation in our view.

Assumption #2 - Overconfidence: We as investors will never be smarter than the whole of the market. That is a key element to understand and respect. Thus the second assumption is that investors are over-confident in their investment abilities. This is a straight forward assumption but very difficult to quantify in practice. Knowing that investor overconfidence (also framed as investor under-reaction) can take stocks and markets to new highs well after the fundamental picture has deteriorated to the point of leaving even the most sophisticated fundamental analyst scratching their head. I attempt to overcome this behavioral shortfall by keeping a healthy respect for the information that the market provides and if a trade or investment isn’t working as anticipated, I don’t wait around for the market to prove me right. In aggregate the Fishbone directional trading probability is right almost 62% of the time. That means it is wrong 38% of the time. Quickly surveying the investment landscape and realizing when one of those 38 percenters have been introduced to the portfolio and eliminating the threat quickly is paramount to portfolio performance. I’d rather take several smaller losses and admit a miscalculation than have a few holdings deteriorate the gains in the portfolio as I stubbornly wait for the market to wise-up to my way of thinking. That doesn’t usually end well.

Assumption #3 – Overreaction: As a result of assumption #2, when it finally comes to light that investors had been wrong in their highly confident investment projections and the market moves against them, there are at times an over-reaction to the new market dynamics. Highly volatile and large price swings can be a result of this phenomenon. This is a condition that I think I struggle with the most. Having the courage and discipline to remain in control and adhere to a contingency plan in the face of extreme market turmoil is difficult. As an investor, I set out to battle through emotional shortcomings when the market dynamics become excessively turbulent. I haven’t always succeeded in the task but the lesson hasn’t been lost and through self-reflection I hope to better control this aspect of portfolio management.

Assumption #4 – Herd Mentality: Market participants will formulate patterns and procedures that become a self-fulfilling prophecy. This herd-like behavior from market participants is what allows technical analysis to flourish in my opinion. Why is it that certain patterns and trends tend to hold so often? The greater a specific pattern or trend is recognized by a group of investors the more relevant it becomes. Trend analysis is a dominant trait in the Fishbone model.

Fishbone Model   

The Fishbone model attempts to recognize oversold opportunities (negative sentiment) in an up-trending market (positive momentum). It also attempts to find overbought opportunities (positive sentiment) in a down-trending market (negative momentum).

To track momentum we incorporate the distance between the 20 and 50 day moving average (DMA) and the 50 and 200 DMA. We also incorporate the moving average convergence divergence (MACD) histogram using the MACD daily variables 60, 130, 45. When aggregated together it produces a bar chart that seeks a mean reverting zero balance. The outer bounds are infinite so the further out the indicator ventures from zero (+/-) the greater the momentum reading. An increasing figure represents positive momentum and a declining figure represents negative momentum. The figures below represent the Fishbone momentum reading back to the year 2007.

 
 
 
 


 
 
 
 
 
 

To track the shorter-term sentiment within the longer-term momentum profile we use a combination of two oscillators. The relative strength indicator RSI (5) and fast stochastics %K (14). This is an oscillator with the outer bounds of 0 to 10. Those investments that exhibit a reading of 8 or better are considered overbought and those investments with a reading of 2 or less are considered to be oversold. The following graphic shows the Fishbone oscillator going back to the year 2007.

 
 
 
 
 
 

While the Fishbone model was designed and tested for use in an established portfolio for the purposes of portfolio protection or enhancement, we launched the model as a standalone investment vehicle and have funded it for the purposes of tracking and monitoring its success or failures. We will be releasing the quarterly results of the model as we progress. While back-testing is important for establishing conceptual integrity, only through actual investments and the building of a track record will the execution of the model be proven. In the model we trade stocks, ETF’s and options on stocks and ETF’s. We do not allocate more than 5% of the total portfolio to any one single idea and are sector agnostic in our equity selection. We do not venture outside companies that reside in the S&P 500. We use a systematic and objective approach to selecting which securities will go in the portfolio but keep a subjective eye towards miscalculation and a low tolerance for positions that are quickly proven to be a net negative to the portfolio (tight stops).

Bottom Line: The Fishbone model was created to focus on the investor phycology part of the investment decision-making process. It combines several behavioral rules and establishes short and long term parameters to find investment opportunities with the highest likelihood of success. We strive to buy securities with positive long-term momentum but negative short-term sentiment. We will short securities with negative long-term momentum but positive short-term sentiment.
