Taaffeite Capital Management

"Is a new kind of quant, combining AI wizardry with old-school biology to trade futures."

- Bloomberg

A letter from our Founders

For years, quantitative investing has been about using computers to find patterns or inefficiencies in market data that can be exploited systematically for profit.

Quant 2.0 is the next generation of quantitative investing.  It is about using artificial intelligence (AI) techniques that avoid over-fitting, look for all profitable patterns in data (not just trends), only trade liquid markets, and are much more disciplined on left-tail risk (not just using volatility to measure risk).  This is what makes TCM's Program so significant.

For over 10 years, Desmond's academic work has focused on unraveling the complex interactions that underlie living cells using machine learning and other computational methods.  As he did this work, it occurred to him that financial markets are similar to cells — both are highly-complex systems that arise from extremely large networks of interactions. So he utilized ideas from his work in computational biology to develop systems that predict the behavior of financial markets, culminating in the TCM Program, which began trading in 2013.


We seek to deliver absolute return that is scalable, uncorrelated with major asset classes, and consistent over diverse market conditions. We see that machine learning is beginning to have a significant impact on asset management, but firms with deep expertise and a robust, sophisticated, tested strategy are very rare. Our name Taaffeite (one of the world's rarest gemstones) was chosen to connote this sense of rarity, and we will utilize our unique expertise and technology for the benefit of our investors.


We look forward to working with our investors at the forefront of the technology of asset management.

An Interview with our CIO, Dr. Lun

Dr. Desmond Lun discusses quantitative investing.

Our History

Taaffeite Capital Management was co-founded by Howard Siow and Dr. Desmond Lun, a renowned academic with a 15-year career spanning MIT, Harvard, and Rutgers, and a leading global expert in computational biology and artificial intelligence.


Taaffeite utilizes a machine learning trading system, the TCM Liquid Alpha Program, that Dr. Lun developed over 10+ years.   This trading strategy, which leverages ideas and techniques from Dr. Lun’s extensive academic work in computational biology, identifies highly-complex, persistent price patterns that are used to predict future price movements of a strategic basket of futures contracts.  Dr. Lun began trading his own capital using the Taaffeite AI system in 2013, and the TCM Liquid Alpha Program was officially launched.


“Dr. Desmond Lun's research into one of the natural world’s most byzantine systems — the biological cell — has given him an edge in untangling the secrets of financial markets.”


What We Do

TCM Liquid Alpha Program:


The TCM Liquid Alpha Program trading strategy holds a diversified strategic basket of long and short positions in 25 liquid global indices.  This basket is systematically rebalanced once a day based on a probabilistic forecast of how those indices will move over the next 24-hours.  The system trades index futures, as opposed to other instruments, to capitalize on the liquidity and lower transaction costs of futures.


Examples of the indices traded:

  • Equities:  S&P 500, FTSE 100, Euro STOXX 50, DAX 30
  • Interest Rate:  US Treasury Notes, Euro-Bund, 10-Year Govt. of Canada Bond
  • Foreign Exchange: Euro, British Pound, Japanese Yen, Canadian Dollar

Our Investment Process

TCM’s investment philosophy is based on the notion that price patterns exist but profitable price patterns are highly complex and short-lived.  Furthermore, identifiable price patterns that exist in single markets are already crowded and unlikely to yield significant profit and could incur significant tail risk if they use rules like stop-losses.


Instead, the key is to search for and identify price patterns involving a large number of markets simultaneously.  Because of the huge number of variables and possible interdependencies that must be considered, humans have little hope of successfully identifying such patterns with any reliability.  TCM’s AI-based system is well-suited for such complex pattern recognition tasks.

The TCM Liquid Alpha Program executes four steps in real time:

Find predictive relationships in the data


Forecast movement of instruments over next 24 hours


Construct the portfolio with focus on capital preservation


Learn and improve


Risk Management

The TCM Liquid Alpha Program constructs the portfolio each day with a focus on capital preservation.  Protecting investors’ capital against tail events means adhering to five core principles:

Investment Objective

Portfolio is selected for capital preservation.

Diversifying into negatively correlated positions.



Alpha Decay

Kolmogorov-Smirnov test is used to determine if last 20 days of daily returns are distributed as expected.  If otherwise, the Program is paused for analysis.

Highly Liquid Instruments

Less than 1% of daily liquidity of instruments so the Program does not get stuck in any positions.



Positive Skew

Many strategies have negatively skewed return distributions.  TCM’s strategy has a longer, fatter, positive tail. (see chart)

Position Management

100% Systematic.  Actively scales in and out of trades.  This allows the Program to maintain some exposure if timing is early and market moves against position.


“Causal interactions are important for both biological and financial systems. It’s what makes them complex,” notes Dr. Desmond Lun. “If you have a causal relationship, you can make predictions and be somewhat confident in them.”
