The study explores why some stocks don't follow the usual rules of stock market predictions. By using a different model called the consumption-based CAPM, the researchers found that it can explain these anomalies. This model suggests that low-risk stocks actually give higher returns than expected, while high-risk stocks give lower returns. It also shows that smaller and undervalued companies tend to perform better than predicted. This new approach sheds light on why some stocks behave differently in the market.
