What is Dual-Momentum Investing?

Dual-Momentum Investing refers to a strategy that considers both absolute momentum (also known as time-series momentum) and relative momentum. Absolute momentum looks at an asset's performance against its own past performance, whereas relative momentum compares the performance against other assets.

Theory Behind Dual-Momentum

Absolute vs. Relative Momentum

• Absolute Momentum: Checks an asset's performance against itself based on historical data.
• Relative Momentum: Compares the performance of various assets to one another, selecting those that performed the best.

Foundations of Dual-Momentum Backtesting

How to Conduct a Dual-Momentum Backtest

To carry out a dual-momentum backtest, one must possess a certain level of understanding of both investment strategies and statistical analysis. The use of statistical software or a platform that allows for backtesting of strategies is essential in obtaining useful data.

Steps in Dual-Momentum Backtesting

1. Data Collection:

• Requires historical price data of the assets you wish to test.

1. Identifying the Look-Back Period:

• Determining the timeframe over which to measure momentum.

1. Calculation of Momentum:

• Utilizing the chosen look-back period to calculate momentum.

1. Strategy Implementation:

• Applying absolute and relative momentum criteria to decide on asset allocation.

1. Performance Assessment:

• Evaluating the results of the backtest to measure the success of the strategy.

Tools and Resources for Backtesting

• Software like R, Python, or specialized backtesting platforms
• Historical market data sources

FAQs on Dual-Momentum Backtesting

What is the ideal look-back period for dual-momentum strategies?
The ideal look-back period can vary and is often determined by individual strategy preference and historical data's availability.

Can dual-momentum strategies be applied to asset classes other than stocks?
Yes, dual-momentum strategies can be used with a variety of asset classes, including bonds, commodities, and currencies.

How do I know if my backtesting results are statistically significant?
Statistical significance is measured through p-values and confidence intervals, where lower p-values typically indicate that the results are less likely due to random chance.

Remember that backtesting is not a guarantee of future performance, and the markets are always changing, which means strategies must adapt accordingly.
