We put the power of award winning high-performance investment algorithms in your hands. Our True Sector Rotation algorithms hold the momentum leader during bull markets and our Dual Defense algorithms mitigate bear market downside risk by selecting only defensive leaders. Both are required to simultaneously improve returns and reduce risk.

Low-Noise Momentum Signals
A momentum strategy's performance depends on its ability to extract trend signals from noisy market data. Our low-noise signal processing algorithms employ the cross-disciplinary sciences of both Matched Filter Theory and Differential Signal Processing, which are the same technologies that enable WiFi, USB, iPhones, and remotely controlled rovers on Mars to perform so well. Simply put, cleaner momentum signals lead to better decisions.

Risk mitigation is a complex problem. Diversification’s passive risk dilution is just the start. Research shows that risk avoidance is the most proficient way to reduce risk. Particularly, avoidance of momentum laggards and bear markets. StormGuard assesses market risk using four key metrics: Trend, Momentum, Sentiment , and Volatility, and a dozen other confirmation indicators. Together they form a superb Bull-Bear indicator and trigger Bear Market Strategies.

Dual Defense: Backstops
StormGuard™ acts as the first line of defense when market momentum fails. TrendGuard™ acts as a second line of defense by incorporating a Defensive Backstop to compete directly with the Model’s candidate funds for momentum leadership by providing a performance floor in case the candidate funds begin performing poorly separate from the broader market. It’s like having a guard dog at the front door and a guard dog at the back door to avoiding loss.

Bear Market Strategies
When our StormGuard market direction indicator signals that market conditions have become bearish, its integrated Bear Market Strategy automatically takes charge and substitutes a set of defensive fund candidates in place of the equity fund candidates employed during a bull market. Bear Market Strategies then select the momentum leader from among their defensive candidates, such as a variety of bond, treasury, and commodity funds.

Hindsight Bias Removal
We remove hindsight bias in two ways:

 • Forward-Walk Progressive-Tuning
   FWPT tunes the momentum filter with
   prior data for use only in the future.
   Evaluations use out-of-sample data.

• Genetic Algorithm - Merlyn.AI
   A Genetic Algorithm evolves sets of
   momentum strategy candidate ETFs
   based on past performance and uses
   them only with out-of-sample data.

 Temporal Portfolio Theory:

This Is Not Your Granddaddy's Portfolio Theory!

Temporal Portfolio Theory (TPT) is an extension to Modern Portfolio Theory (MPT) that incorporates the analysis of temporal (time series) data in a manner that was simply not possible in 1952 when MPT was developed. Thus MPT was constrained to buy-and-hold diversify-and-rebalance models. Today, the advent of instant electronic market data and previously unimaginable computing power has changed everything. But TPT is not about the race to trade a microsecond faster, it's not about AI trying to tease out unseen predictive correlations, and it's not about creating one more temporal analysis indicator for today's technical trading platforms. 

It's About Noise Reduction and Risk Avoidance!

In 1948 Claude Shannon of Bell Labs proved that the probability of making a good decision is directly proportional to a system's Signal-to-Noise Ratio. In 1946 J. H. Van Vleck developed Matched Filter Theory to optimize Signal-to-Noise Ratio. In 1993 Jegadeesh and Titman published their seminal academic paper proving momentum exists in market data, but they used a 12-month Simple Moving Average for their momentum filter – definitely far from optimum. Furthermore, the optimum filter depends on the class of assets involved, varies with the market's temperament, and must deal with punctuated events. Solving these problems is what Temporal Portfolio Theory is all about.
