AlphaDroid investment strategies and portfolios level the playing field with Wall Street by putting the power of award-winning, high-performance investment algorithms in your hands.

Cleaner momentum signals lead to better decisions.


Momentum Detection: It’s About Reducing Noise

The performance of momentum investing depends on its proficiency in extracting trend signals from noisy market data. Our advanced signal processing algorithms employ the cross-disciplinary sciences of Matched Filter Theory and Differential Signal Processing – the same technologies that enable WiFi, USB, iPhones, and remotely controlled rovers on Mars to perform so well.

Our goal is to produce low noise momentum that leads to:

  • Better fund selection
  • True sector rotation owning only the leader and avoiding the laggards

StormGuard™ – Market Risk Assessment

Risk is a complex problem, and diversification’s passive “risk dilution” is only just the start. Our research shows the most proficient way to reduce risk is through “avoidance” – specifically, avoidance of laggards and bear markets. StormGuard assesses the risk of U.S. equity markets using four key metrics: price-trend, market momentum, value sentiment, and market volatility.

StormGuard, our proprietary Bull-Bear Indicator clarifies our process to:

  • Pick defensive funds
  • Avoid rather than dilute risk

Bear Market Indicated

Bull Market Indicated

When StormGuard indicates a bear market, each of the portfolio’s underlying strategies selects a momentum leader from among a defensive set of candidate ETFs (such as bonds, treasuries, commodities, and others). StormGuard acts as Dual Defense’s first line of defense.

In Bull Markets, each of the underlying momentum strategies within a portfolio select a momentum leader from among a set of candidate equity funds, which includes a broad “backstop” fund designed to act as a performance floor for the Strategy. We refer to the backstop’s defensive benefit as “TrendGuard,” the second line of defense of Dual Defense. Most AlphaSheet portfolios incorporate the TRM (Tactical Risk Mitigation) Portfolio as its backstop.

Conquering The Seven Faces of Risk

"This book is one of the very few ‘must read’ books. For those who have been burned by the ‘diversify and rebalance’ mantra, Conquering the Seven Faces of Risk is sorely needed, and Scott Juds truly delivers. As a fiduciary, I find SectorSurfer’s risk mitigation algorithms to be so far superior to the conventional buy-hold-and-rebalance models that I cannot justify risking my clients’ assets with the latter. I am impressed with Scott Juds’ mission to educate the retail investing community."

  • The FEDS (FINRA, ERISA, DOL, SEC) are silent on quantitative measures defining suitable and prudent risk management.
  • While a wide latitude helps advisors satisfy client needs, it provides no basis for defense in a risk management audit.
  • However, industry consensus definitions for risk-ranked portfolios are entrenched and accepted by the FEDS. Thus, their risk measures quantify suitable and prudent risk.
  • Extracting trend signals from noisy  market data in a manner that has been the most  predictive of next month's performance.
  • Walking forward in time through new out-of-sample data using the previously determined best performing momentum algorithm.
  • Fully automating the process to allow investor to focus on the higher level task of choosing candidate sets of funds that play well together.
  • Modern Portfolio Theory is 65 years old, developed long before computers could analyze daily time domain data.
  • Temporal Portfolio Theory extends MPT by utilizing the cross-disciplinary sciences of Holistic Risk Management, Matched Filter Theory and Differential Signal Processing
    to improve overall investment performance.
  • Only by owning the trend leader and avoiding the laggards can one simultaneously improve returns and reduce risk!

We believe momentum detection is the key to profitable fund selection for both bull and bear market holdings. The challenge is to see past market noise to select momentum leaders. In unusual equity markets like we’ve experienced from 2021 through 2023, momentum signals can become degraded by market noise resulting from policy-induced reversals. TrendGuard can then become an important defensive tool that seeks to provide a performance floor when longer term momentum can’t get traction. Together with StormGuard, this approach provides what we call Dual Defense.
