Converting Unstructured To Structured Data With Prattle Analytics
by Erez Katz, CEO and Co-founder of Lucena Research.
One of our more exciting data partners on the Nasdaq Analytics Hub is Prattle, a company that prides itself on transforming unstructured communications into structured data from which it’s easier to derive intelligence. In a previous newsletter, I covered how Prattle is able to discern macro-level sentiment from monetary policy communications of central bank officials (in both spoken and written forms). Specifically, I demonstrated how Prattle’s data can be used in a foreign exchange strategy.
Prattle has recently expanded its offerings to include corporate communication data. Similar to macro-level sentiment, Prattle can now identify equity level sentiment through applying natural language processing (NLP) and machine learning of unstructured corporate earnings calls and their corresponding follow-up Q&A sessions.
What Is The Difference Between Structured And Unstructured Data?
Structured data refers to digitized information with a high degree of organization in a readily searchable format (for example, time series data that can be expressed in rows and columns). Unstructured data is essentially data that is not easily searchable such as verbal communication or free text. This lack of organization makes deriving intelligence from such data a time and energy-consuming task.
Prattle Corporate Communication-Based Sentiment
Lucena was tasked with two main goals:
- Validate Prattle's equity sentiment through its corporate communication data historically.
- Enhance Prattle’s core expertise by introducing machine-learning-friendly features.
Through a regimented process, we loaded Prattle’s historical dataset and analyzed their data for consistency, completion, survivor bias and more. More importantly we’ve analyzed the correlation between Prattle’s corporate sentiment data and future returns. We then created additional features to allow our machine learning disciplines to further hone in on the most predictive set of features for various market regimes.
Below is a backtest conducted on QuantDesk® that identifies which features (both Prattles’ native features and Lucena’s enhanced features) are most suitable for the Dow 30.
Prattle DJI Long is predicated on two Prattle earnings calls score indicators:
- The Average Score Value is the rolling simple average of earnings call scores over a 252-day period.
- The Score Difference Rank is the difference between the most recent earnings call score and the preceding earnings call score (as long as it not older than 252 days), then ranked against the Russell 1000.
A buy signal occurs when stocks in the Dow conform to both indicators. Positions are held in the portfolio as long as they continue to conform to both indicators. When one or the other indicator is no longer active, a sell signal occurs.
Combining Prattle’s Data With Traditional Fundamental And Technical Data
In addition to evaluating a strategy utilizing Prattle’s data exclusively, Lucena’s technology is capable of identifying those indicators that, when used together with Prattle’s, can provide even greater forecasting capabilities.
Prattle Corp Comm is a long-only backtest that demonstrates the efficacy of applying machine learning to create a multi-factor model based on Prattle's corporate communications sentiment combined with fundamental and technical data. The backtest trades daily based on a conditional scan. Every day the system scans the Russell 1,000 and searches for stocks that meet a multi-factor scan criteria. Including:
- Beta Rank
- Free Cash-flow Rank
- Prattle Most Recent Sentiment Score
The stocks that met the scan are then equally weighted based on a predetermined daily allocation. The positions stay in the portfolio as long as they continue to meet the scan criteria. The concept of holding stocks conditionally vs. predetermining an arbitrary hold time (one month, for example) allows for a more dynamic holding time based on market and stocks’ idiosyncratic conditions. The in-sample training timeframe is limited to 2010. All remaining years are completely out of sample. Transaction costs are estimated at 5 bps round trip and are netted out of the total return. Benchmark is RUI (the Russell 1000 index).
Through a well-defined process, Lucena is able to validate if a data source is production-ready and predictive. Additionally, Lucena is able to create machine learning-friendly features and determine if combining a data vendor’s features with those of Lucena (as well as unrelated features, such as fundamental and technical) can enhance the data’s predictive power.
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 has been forward traded since 2014 and to date it has enjoyed remarkably low volatility and boasts an impressive return of 50.93%, low volatility as expressed by its max-drawdown of only 6.16%, and a Sharpe of 1.95! (You can see a more detailed view of Tiebreaker’s performance below in this newsletter.)
BlackDog – Lucena’s Risk Parity - YTD return of 14.85 % vs. benchmark of 12.63%
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 41.35% vs. 14.11% 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.
Industrials - Large-Cap Based Actively Managed - YTD Return of 19.80% vs. benchmark of 13.20%
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.
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.

The table below presents the trailing 12-month performance and a YTD comparison between the two model strategies we cover in this newsletter (BlackDog and Tiebreaker), as well as the two ETFs representing the major US indexes (the DOW and the S&P).
Model Tiebreaker, Lucena's Active Long/Short US Equities Strategy:
Model BlackDog 2X: Lucena's Tactical Asset Allocation Strategy:
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).
