Intraday return predictability: Evidence from commodity ETFs and their related volatility indices

Area of Science:

• Financial Markets
• Quantitative Finance
• Market Microstructure

Background:

• Intraday momentum, the predictability of short-term returns within a trading day, is a key area of financial market microstructure research.
• Understanding intraday return patterns is crucial for developing effective trading strategies and risk management.

Purpose of the Study:

• To analyze intraday return predictability patterns in crude oil, gold, and silver exchange-traded funds (ETFs).
• To investigate the relationship between intraday momentum and market volatility.
• To assess the economic value of market timing strategies based on intraday momentum.

Main Methods:

• Utilized high-frequency data for crude oil, gold, and silver ETFs and their associated volatility indices.
• Employed econometric techniques to identify and quantify intraday return predictability.
• Simulated market timing strategies to evaluate economic value.

Main Results:

• Confirmed the existence of intraday return predictability across all studied markets (crude oil, gold, silver ETFs).
• Observed distinct patterns of predictability, with specific half-hour intervals showing significant predictive power for later intervals.
• Found that intraday momentum is more pronounced on high-volatility days and days with significant price jumps.
• Demonstrated substantial economic value generation through market timing strategies exploiting intraday momentum.

Conclusions:

• Intraday momentum is a prevalent phenomenon in commodity and precious metal ETFs, though its manifestation varies by asset.
• Market volatility and price jumps amplify intraday return predictability.
• A market timing strategy based on intraday momentum can be profitable across these markets.
• Potential explanations include investor behavior such as infrequent portfolio rebalancing and delayed information incorporation.
