Assets invested in passively managed equity mutual funds and exchange traded funds (ETFs) have grown steadily in recent years, reaching more than one trillion dollars at the end of 2010. Through a battery of tests, we establish that the rise in popularity of index investing contributes to higher...

The authors found that the rise in popularity of index trading — assets invested in index funds reached more than $1 trillion at the end of 2010 — contributes to higher systematic equity market risk. More equity index trading corresponds to increased cross-sectional trading commonality,...

Therefore, investors who seek...

Using a comprehensive sample of investment recommendations, we investigate differences in the performance, behavior, and career outcomes of male and female sell-side analysts. Compared to their male counterparts, we find that the recommendations of female analysts produce similar abnormal...
