Quant Radio: Can Dividend-Price Ratio Predict Stock Return?
In this video, we explore a fundamental question in finance: Are stock returns predictable? We focus on one classic metric — the Dividend-Price (DP) Ratio — and dive into a major research study that puts its predictive power to the test.
What You'll Learn:
- What the DP ratio is and why it might predict market returns
- How researchers tested this idea using nearly 90 years of S&P 500 data (1927–2017)
- The difference between in-sample and out-of-sample testing
- What statistical significance and RMSE (Root Mean Square Error) mean for forecasting accuracy
- The study’s findings, including a meaningful 7.8% R² in-sample and a 3.42% RMSE out-of-sample
- Important limitations: short-term focus, single-variable model, and implications for long-term investors
Whether you're a finance student, investor, or just curious about how market prediction works, this video offers an insightful look into academic research and the methods behind it.
Join us as we unpack the data, the theory, and the limitations — and ask what it really tells us about market predictability.
