Commodity funds predict market returns, changing investment strategies forever.
The study looked at how commodity mutual funds and commodity markets are related from 1997 to 2015. Traditional tests didn't show a clear connection, but when using wavelets to analyze the data, a positive relationship was found in the short-term and from 2008 to 2015. Specifically, fund flows predicted returns from 2008 to 2012, but then the causality switched. This shows that a time-varying approach is important when studying commodity returns and flows, especially when dealing with nonlinearity and structural breaks.
