I'm a finance and accounting person by education and trade, having worked everywhere from very large corporations to very small companies - doing financial reporting and accounting work, with some IT support mixed in along the way. I grew up in Tacoma, WA, and have lived in Phoenix, AZ since 2003. Blessed to have a great wife and kids.

Dual Momentum Systems is the personal project that grew out of a long-standing desire - as an ordinary investor myself - to capture most of the market's upside while avoiding the worst of its drawdowns. It really took flight when I discovered Gary Antonacci's Global Equities Momentum work, which sparked my interest and passion for creating tactical asset allocation models - this was the genesis of DMS.

Everything on this site - the strategies, the backtests, the tools - is free for personal use. Strategies deemed Premium will not show allocations until after the 10th of the month; you can uncover them during the first 10 days by subscribing. DMS was built to be the kind of resource I wish I'd had when I started thinking seriously about my own portfolio - and I use it all the time myself.

I hope you enjoy the site and become a frequent visitor, finding it a useful tool.

Dual Momentum Systems exists to make disciplined, momentum-based investing transparent and approachable — with an emphasis on avoiding prolonged downturns. Strategies are published with their actual out-of-sample performance alongside long backtests — nothing hidden, nothing cherry-picked.

The foundational principle behind all of it is the same: excellent risk-adjusted returns. Strong returns matter, but how those returns are earned — and how much risk it took to earn them — matters even more.

What you'll find here

Strategies — active momentum strategies, some without leverage and some that use 2X or 3X Smart Leverage.
Stock Strategies — an equities strategy: a rules-based, high-conviction momentum stock strategy.
Allocation strategies — tax-efficient, low-maintenance alternatives to a classic 60/40 portfolio with better risk/reward profiles.
Portfolios — blended mixes of strategies and holdings with compelling risk-adjusted metrics.
AutoPilot — several strategies can be auto-traded through the AutoPilot platform.

Key concepts

Smart Leverage — using leverage opportunistically, when conditions are favorable for the use of leveraged ETFs.
Treasury Duration Limiter — a method of going long or short duration treasuries when going Risk Off in the Global Navigator strategies.

More detail on the mission, each individual strategy, and these concepts is being added here.

Welcome to DMS | Dual Momentum Systems

Capture more of the upside.
Avoid the worst drawdowns.

A collection of disciplined, momentum-based investment strategies and allocation strategies built on one principle: excellent risk-adjusted returns. Published with real out-of-sample results alongside long backtests - nothing hidden, nothing cherry-picked.

Proof, not promises

Strong returns, earned with far less risk. Two examples, measured over the long term against industry benchmarks.

Every number above is computed live from the same data feed that powers the rest of the site, and updates automatically after each month closes. Global Navigator 300 uses Smart Leverage. Past performance doesn't guarantee future results - the biggest drawdown a strategy will experience is still to come.

Built to keep you invested

Shallower drawdowns

Sidestep the worst of bear markets, so recovering doesn't mean climbing out of a deep hole first.

Lower volatility

A smoother ride is easier to stick with - and staying invested is where compounding actually happens.

Strong risk metrics

Sharpe, Sortino, and drawdown numbers that stand up to scrutiny - not just headline returns.

Out-of-sample & backtested

Every strategy shows its real, live results next to a long backtest, so you can judge it for yourself.

Pick the strategies that best suit you.

Tactical Asset Allocation

Momentum strategies

Rules-based models that rotate into strength and step aside from weakness. Run them unleveraged, or with Smart Leverage for a more aggressive profile.

Systematic, emotion-free rules
Unleveraged or Smart Leverage variants
Simple enough to run yourself (DIY)

Allocation

Set-and-forget portfolios

Tax-efficient, low-maintenance alternatives to a classic 60/40 - with better risk/reward and only annual rebalancing.

Rebalance just once a year
Tax-advantaged by design
A better core than 60/40

★ Most asked-about

Smart Leverage

Leverage usually means bigger losses when things go wrong. Smart Leverage flips that: it applies leverage only when the odds are most in your favor, and steps back to safety when they're not.

The aim is simple - higher returns, not higher losses. Global Navigator 300 above nearly doubled the S&P 500's annual return while cutting the worst drawdown by more than half.

When it engages

After a large month-end drawdown in the broad U.S. market (IWB) - leaning in when recoveries have historically paid the most.

The goal

Opportunistic upside, not reckless risk. Leverage is used only when conditions favor it.

Where you'll find it

Offered on select tactical strategies, including the Triad and Global Navigator families.

From the founder

Hi, I'm Randy Harris - the person behind Dual Momentum Systems. I'm an ordinary investor who wanted to capture most of the market's upside while avoiding the worst of its drawdowns.

DMS started with an interest in Gary Antonacci's dual momentum work, and grew into a stable of excellent strategies that I use myself.

The DMS website is a great tool for looking at strategy performance, comparing them to benchmarks and other strategies - so much to take advantage of. Thanks for stopping by, enjoy the site and strategies, and reach out any time with questions or comments.

Thank you,

Randy
