If AI Is The Future Then The Future Is Here!

Erez Katz writes about Betting On US Defense Stocks

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

In my nearly three decades-long career as a serial technology entrepreneur, I have witnessed three distinct “aha” moments in which I realized that the world was about to change in a profound and permanent way. The first was after suffering an injury in my 20s and had to spend six months on bedrest and crutches, rarely leaving the house. My father, watching me become nearly insane with boredom, bought me my first PC (an Apple 2e) in the late 80’s.

It was well before PCs became ubiquitous, but I knew that I was witnessing one of the biggest technological marvels in history. It was then that I made a conscious decision to make software development a career goal.

The second “aha” moment came while I already had a successful software business and the first PDA (Personal Digital Assistant), the Palm Pilot, made its debut in the late 90’s and early 2000’s. I knew that bringing computing power to someone’s pocket with the ability to consolidate information and act on it on-the-go was revolutionary and would change the way people live their lives. (I recall the moment when it hit me, when I was on vacation with my wife and kids in the Cayman Islands. While everyone else was swimming and enjoying the beauty of the island, I kept holding my Palm device, testing my first software application. When my daughter came up to me and said “Daddy, put that thing down!” I told her “You don’t understand. The world is about to change in a major way!” People stared at me as if I lost my mind, and my family laughs about it to this day.)

Image 2: Palm Pilot was popular in the early 2000. It helped paved the path to the smartphones we use today.

Now, about two decades later, the same excitement has hit me now for the third time. Artificial Intelligence using neural networks and deep learning is so profoundly transformational that I am confident that it will continue to change our lives in a major way. As in previous “aha” moments, the realization of major, transformational changes took a few years to be broadly adopted and become ubiquitous. Today, many hear about artificial intelligence and data science but very few truly understand the magnitude of its impact. Through this medium we can bridge between complex academic concepts and real-life applications. Very soon, applying artificial intelligence to decision making (finance included) will be essential to staying relevant, not to mention competitive, and will transform our lives in an extraordinary way.

In the coming weeks, I will attempt to reference real-life examples coupled with cool and informative online short videos of how AI and specifically deep neural networks (deep nets) are solving complex real-life problems. I believe that within short order it will become apparent to you as well where this data-meet-science revolution is heading.

Introduction to Artificial Intelligence Investing

To get us started, here is a great introduction to Neural Network video that showcases the concept of hand writing recognition (the “Hello World” of AI and Neural Nets) in a beautifully annotated graphical animation.

In the coming weeks, I will attempt to reference real-life examples coupled with similar informative short videos of how AI and specifically deep neural networks (deep nets) are solving complex real-life problems. I believe that within short order it will become apparent to you as well where this data-meet-science revolution is heading.

Strategies Update

As in the past, we will provide weekly updates on how the model portfolios and the theme-based strategies we cover in this newsletter are performing.

Tiebreaker – Lucena’s Long/Short Equity Strategy - YTD return of -0.64% vs. benchmark of 0.43%
Image 1: Tiebreaker YTD– benchmark is VMNIX (Vanguard Market Neutral Fund Institutional Shares)
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 50.65%, low volatility as expressed by its max-drawdown of only 6.16%, and a Sharpe of 1.74! (You can see a more detailed view of Tiebreaker’s performance below in this newsletter.)

BlackDog – Lucena’s Risk Parity - YTD return of -0.76% vs. benchmark of -1.53%

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.

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.

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 4: 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.

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.
