The Future Of Machine Learning Is Here

Erez Katz writes about Reducing Turnover Through Quantitative Research

by Erez Katz, CEO and Co-founder of Lucena Research.

Background:

As the market continues to move higher, Lucena’s strategies also continue to outperform. Our strategies -- whether model portfolios or made-to-suit -- are mostly designed to maximize risk-adjusted returns, important distinction from just maximizing returns. Risk exposure is an important element of every strategy we design since it is only a matter of time before markets correct, and corrections occur when they are least expected.

Our strategies are heavily reliant on machine learning disciplines specifically designed to limit exposure to market corrections. In addition, all of our strategies have been tested against challenging market regimes such as the recession of 2008 and, more recently, the correction of 2011.

It’s exciting to see how even the basic application of machine learning can benefit an investment strategy so greatly. This is mainly because many investment professionals still don’t know how to properly adopt machine learning into their investment process. However, it’s only a matter of time before basic machine learning implementation becomes mainstream and loses its competitive edge. Therefore, it’s important to understand the current and future trends in machine learning.

While the content below is mostly technical, I highly recommend reading through it. I have tried to simplify complex concepts, hoping that it will pique your interest to investigate further.

Probabilistic Programming

Before I get into probabilistic programing, let me review some high-level concepts in machine learning.

Machine learning is an application of artificial intelligence (AI) that enables software with the ability to learn and improve from data and experience without being explicitly programmed.

Machine learning can be categorized into two main groups:

  • Supervised Learning and Regression – Deterministic forecasting based on many observations and their respective outcomes. The machine learning process tries to construct a mathematical formula that generalizes the relationship between input variables and a desired outcome. Regression looks mainly at cause and effect or reference based on inductive reasoning where we can simply derive an outcome from plugging in input variables.
  • Unsupervised Learning and Classification – In contrast to supervised learning and regression, unsupervised learning makes no assumption of a desired outcome. The data is grouped based on output similarities or highly correlated end states. This process is also known as clustering. Once clusters are formed, the machine tries to infer or rationalize what path of variables and states provides the highest probability for an output associated with an outcome.

The process of generalization is what enables the inductive and deductive reasoning in machine learning. By generalizing a problem and its solution, the machine can infer an outcome from seemingly unseen situations. Inductive reasoning is often associated with bottom up supervised learning (many samples of input evaluated in the context of a desired outcome). While deductive reasoning is often associated with top down unsupervised learning (inferring which path of events most likely took us to the outcome presented). Many scientists consider unsupervised learning and classification to be more difficult to generalize as the clusters are not constructed with a specific problem in mind and there could be endless paths that could be considered for the way data is classified.

Probabilistic programming is software designed specifically to analyze complex classification problems. Traditional software was developed to work linearly through a linear sequence of code execution. However, linear execution is not suitable to solve complex graphical models such as Bayesian Network or Markov Random Field. Probabilistic Programming is software derived from traditional languages that is designed to “fork” into multiple paths, so that the most statistically significant path is identified as most likely to determine future outcomes.

Conclusion

In the business of machine learning for investment, complacency and stagnation are the kiss of death. Staying ahead of the curve is critical for sustainability and growth. As machine learning and AI evolves, specialized chips developed by the likes of NVIDIA, Intel and AMD are bound to further revolutionize the AI software development movement. We are truly at the infancy of a revolution bound to change just about every aspect of our lives, with machine learning for investment at the forefront. Future solutions will be designed to replicate human intelligence by which decisions are made from a complex set of dependent and independent experiences over time.

The train has already left the station. It’s time to get on!

Strategies Update

As in past weeks, I want to briefly update you on how the model portfolios and the theme-based strategies we covered recently are performing.

Tiebreaker – Lucena’s Long/Short Equity Strategy - YTD return of 14.74% vs. benchmark of -4.38%

Past performance is no guarantee of future returns.

Tiebreaker has been forward traded since 2014 and to date it has enjoyed remarkably low volatility and boasts an impressive return of 52.62%, low volatility as expressed by its max-drawdown of only 6.16%, and a Sharpe of 1.99! (You can see a more detailed view of Tiebreaker’s performance below in this newsletter.)

BlackDog – Lucena’s Risk Parity - YTD return of 17.87 % vs. benchmark of 14.03%

We have recently developed a sophisticated multi-sleeve optimization engine set to provide the most suitable asset allocation for a given risk profile, while respecting multi-level allocation restriction rules.

Essentially, we strive to obtain an optimal decision while taking into consideration the trade-offs between two or more conflicting objectives. For example, if you consider a wide universe of constituents, we can find a subset selection and their respective allocations to satisfy the following:

  • Maximizing Sharpe
  • Widely diversified portfolio with certain allocation restrictions across certain asset classes, market sectors and growth/value classifications
  • Restricting volatility
  • Minimizing turnover

We can also determine the proper rebalance frequency and validate the recommended methodology with a comprehensive backtest.

Utilities - Large-Cap Based Actively Managed - YTD return of 46.70% vs. 16.35% of the benchmark!!!

I wrote about utilities last year in an attempt to demonstrate how Lucena’s technology can be deployed to identify fixed income alternatives. Since November 2016 we have been tracking our utilities portfolio, and it has been performing exceptionally well in both total return and low volatility -- well ahead of the S&P and its benchmark, the XLU.

Past performance is no guarantee of future returns.

Industrials - Large-Cap Based Actively Managed - YTD Return of 20.48% vs. benchmark of 12.84%

I wrote about an industrial-centric portfolio in January this year. This portfolio was designed to anticipate the administration’s strong desire to invest in infrastructure. The portfolio identifies a well-diversified industrial stock set to track and outperform the XLI (its benchmark).

Forecasting the Top 10 Positions in the S&P

Lucena’s Forecaster uses a predetermined set of 10 factors that are selected from a large set of over 500. Self-adjusting to the most recent data, we apply a genetic algorithm (GA) process that runs over the weekend to identify the most predictive set of factors based on which our price forecasts are assessed. These factors (together called a “model”) are used to forecast the price and its corresponding confidence score of every stock in the S&P. Our machine-learning algorithm travels back in time over a look-back period (or a training period) and searches for historical states in which the underlying equities were similar to their current state. By assessing how prices moved forward in the past, we anticipate their projected price change and forecast their volatility.

The charts below represent the new model and the top 10 positions assessed by Lucena’s Price Forecaster.

Image 5: Default model for the coming week.

The top 10 forecast chart below delineates the ten positions in the S&P with the highest projected market-relative return combined with their highest confidence score.

Image 6: Forecasting the top 10 position in the S&P 500 for the coming week. The yellow stars (0 stars meaning poorest and 5 stars meaning strongest) represent the confidence score based on the forecasted volatility, while the blue stars represent backtest scoring as to how successful the machine was in forecasting the underlying asset over the lookback period -- in our case, the last 3 months.

Appendix

For those of you unfamiliar with BlackDog and Tiebreaker, here is a brief overview: BlackDog and Tiebreaker are two out of an assortment of model strategies that we offer our clients. Our team of quants is constantly on the hunt for innovative investment ideas. Lucena’s model portfolios are a byproduct of some of our best research, packaged into consumable model-portfolios. The performance stats and charts presented here are a reflection of paper traded portfolios on our platform, QuantDesk®. Actual performance of our clients’ portfolios may vary as it is subject to slippage and the manager’s discretionary implementation. We will be happy to facilitate an introduction with one of our clients for those of you interested in reviewing live brokerage accounts that track our model portfolios.

Tiebreaker: Tiebreaker is an actively managed long/short equity strategy. It invests in equities from the S&P 500 and Russell 1000 and is rebalanced bi-weekly using Lucena’s Forecaster, Optimizer and Hedger. Tiebreaker splits its cash evenly between its core and hedge holdings, and its hedge positions consist of long and short equities. Tiebreaker has been able to avoid major market drawdowns while still taking full advantage of subsequent run-ups. Tiebreaker is able to adjust its long/short exposure based on idiosyncratic volatility and risk. Lucena’s Hedge Finder is primarily responsible for driving this long/short exposure tilt.

Tiebreaker Model Portfolio Performance Calculation Methodology Tiebreaker's model portfolio’s performance is a paper trading simulation and it assumes opening account balance of $1,000,000 cash. Tiebreaker started to paper trade on April 28, 2014 as a cash neutral and Bata neutral strategy. However, it was substantially modified to its current dynamic mode on 9/1/2014. Trade execution and return figures assume positions are opened at the 11:00AM EST price quoted by the primary exchange on which the security is traded and unless a stop is triggered, the positions are closed at the 4:00PM EST price quoted by the primary exchange on which the security is traded. In the case of a stop loss, a trailing 5% stop loss is imposed and is measured from the intra-week high (in the case of longs) and low (in the case of shorts). If the stop loss was triggered, an exit from the position 5% below, in the case of longs, and 5% above, in the case of shorts. Tiebreaker assesses the price at which the position is exited with the following modification: prior to March 1st, 2016, at times but not at all times, if, in consultation with a client executing the strategy, it is found that the client received a less favorable price in closing out a position when a stop loss is triggered, the less favorable price is used in determining the exit price. On September 28, 2016 we have applied new allocation algorithms to Tiebreaker and modified its rebalancing sequence to be every two weeks (10 trading days). Since March 1st, 2016, all trades are conducted automatically with no modifications based on the guidelines outlined herein. No manual modifications have been made to the gain stop prices. In instances where a position gaps through the trigger price, the initial open gapped trading price is utilized. Transaction costs are calculated as the larger of 6.95 per trade or $0.0035 * number of shares trades.

BlackDog: BlackDog is a paper trading simulation of a tactical asset allocation strategy that utilizes highly liquid ETFs of large cap and fixed income instruments. The portfolio is adjusted approximately once per month based on Lucena’s Optimizer in conjunction with Lucena’s macroeconomic ensemble voting model. Due to BlackDog’s low volatility (half the market in backtesting) we leveraged it 2X. By exposing twice its original cash assets, we take full advantage of its potential returns while maintaining market-relative low volatility and risk. As evidenced by the chart below, BlackDog 2X is substantially ahead of its benchmark (S&P 500).

In the past year, we covered QuantDesk's Forecaster, Back-tester, Optimizer, Hedger and our Event Study. In future briefings, we will keep you up-to-date on how our live portfolios are executing. We will also showcase new technologies and capabilities that we intend to deploy and make available through our premium strategies and QuantDesk® our flagship cloud-based software.
My hope is that those of you who will be following us closely will gain a good understanding of Machine Learning techniques in statistical forecasting and will gain expertise in our suite of offerings and services.

Specifically:

  • Forecaster - Pattern recognition price prediction
  • Optimizer - Portfolio allocation based on risk profile
  • Hedger - Hedge positions to reduce volatility and maximize risk adjusted return
  • Event Analyzer - Identify predictable behavior following a meaningful event
  • Back Tester - Assess an investment strategy through a historical test drive before risking capital
