Quant Radio: The Intersection of Expected Returns

Dive into the fascinating world of factor investing and discover how a select few stocks—referred to as "overlap stocks"—are the hidden force behind the returns of 164 different investment anomalies.

This video unpacks groundbreaking research by Austin Akka, revealing that these overlap stocks, which consistently appear across multiple strategies, contribute disproportionately to portfolio performance.

Key Takeaways:

Concentration of Returns: Just 10% of overlap stocks drive ~40% of anomaly portfolio returns, with alpha three times greater than non-overlap stocks.

Behavioral Insights: Analyst forecast errors show systematic mispricing—overly pessimistic on winning stocks and overly optimistic on losers.

Simplified Strategy: A focused overlap portfolio (long top 10%, short bottom 10%) historically delivered 12.6% annualized alpha, outperforming even momentum.

Caveats: Transaction costs, performance variability, and real-world trading challenges are critical considerations.

Whether you're a factor investor or just curious about market inefficiencies, this video offers a fresh lens to cut through the "factor zoo" and rethink how you approach alpha generation.
