Introduction

In this insightful episode of Excess Returns, hosts Jack Forehand, Justin Carbonneau, and Matt Ziegler delve into the profound insights shared by Cliff Asness, the founder of AQR Capital Management. Drawing from their comprehensive interview, the hosts extract and analyze the most valuable lessons for long-term investors, touching upon topics such as market efficiency, passive investing, factor strategies, and the psychological aspects of investing.

1. Morning Routines: Debunking the Myth

The episode opens with a light-hearted discussion about morning routines, challenging the conventional belief that a rigid and strenuous morning regimen is essential for success.

• Jack Forehand [02:13]: “I asked Cliff what he thinks about it. I was really excited that you gave all of us a little bit of hope... my morning routine is, alarm goes off at 5:30am I text my trainer, not today. I sleep another hour... I get mad, mad about something.”

• Cliff Asness [03:42]: “These morning routines may be correlated with very highly productive people... but I don't think it's as causative as people think.”

Key Takeaway:
Cliff emphasizes that while morning routines are often associated with productivity, they are not a direct cause of success. Different individuals thrive with varying routines, and it's essential to find what genuinely works for you rather than adhering to societal expectations.

2. Market Efficiency: The Less Efficient Market Hypothesis

A significant portion of the discussion centers around Cliff Asness's perspective on market efficiency, particularly his observation that markets have become less efficient over time.

• Cliff Asness [07:57]: “I believe markets have gotten somewhat less efficient... the speed of trading, the cost of trading has gone down... but the difference is 10 minutes versus 10 milliseconds.”

• Jack Forehand [25:48]: “Cliff's not arguing like there's no efficiency in the market, but you could argue the market is getting less efficient because things are blowing out relative to their value more than they have now.”

Key Takeaway:
Cliff argues that while markets have historically been efficient, recent anomalies like the dot-com bubble and the COVID-19 valuation surges indicate a decline in efficiency. Technological advancements have increased the speed of information dissemination, but the accurate processing of this information hasn't kept pace, leading to potential inefficiencies.

3. Embracing Discomfort in Investing

Cliff Asness underscores the importance of being comfortable with the inherent discomfort that comes with various investment strategies, especially those that may underperform in the short term.

• Cliff Asness [16:12]: “The more you talk about it, I have a presentation where I talk about... get more long term. Don't obsess about the short term as much.”

• Matt Ziegler [20:20]: “Anticipating stress is most of financial planning... you’re only hiring somebody like me or you to do stuff if you’ve actually amassed some wealth or you’re off on some path where you can afford to do the thing.”

Key Takeaway:
Investors must prepare mentally for periods of underperformance and volatility. By adopting a long-term perspective and understanding the cyclical nature of markets, investors can better withstand short-term discomfort and stay committed to their investment strategies.

4. The Passive Investing Debate

The hosts explore the contentious topic of passive investing and its impact on market efficiency, referencing Cliff Asness's discussion on the subject.

• Cliff Asness [28:21]: “There’s only one number we know for sure that can’t be 100%... free riding off everybody else. It’s hard to think about.”

• Jack Forehand [32:24]: “If you believe even if you believe what he's saying about passive... owning The S&P 500 is probably the best thing you could be doing.”

Key Takeaway:
While passive investing offers simplicity and often reliable returns, Cliff cautions against an overly passive market. He suggests that a significant majority of the market cannot be passive without disrupting market efficiency. The debate remains open, with no definitive threshold established for the optimal level of passive investing.

5. Factor Investing and Advancements in Research

The conversation transitions to factor investing, particularly the emergence of factors that lack traditional economic explanations but still deliver returns.

• Cliff Asness [46:17]: “We’re still dealing with economic data, returns, accounting information... we’re moving in the direction of that paper and that is a little hard for me when you've touted something for many years.”

• Matt Ziegler [55:27]: “Cliff was able to give us a response for thinking through this and talk about how it's working inside of AQR. That's very impressive.”

Key Takeaway:
Cliff acknowledges the rise of factor strategies that don't necessarily have a clear economic rationale but have demonstrated empirical success. He advocates for a balanced approach that leverages both economic intuition and advanced statistical techniques, such as machine learning, to uncover and utilize these factors effectively.

6. Managing Behavioral Biases: Look Less Often

Cliff Asness offers a practical piece of advice for investors: minimize the frequency of portfolio reviews to avoid behavioral biases.

• Cliff Asness [37:49]: “Look at your portfolio as little as possible... whoever looks at it more loses.”

• Jack Forehand [40:04]: “What are the positive things that could come of me looking at my portfolio?... nothing for me to change.”

Key Takeaway:
Frequent portfolio monitoring can lead to unnecessary stress and impulsive decision-making. By adopting a long-term investment horizon and reducing the frequency of portfolio checks, investors can mitigate the influence of behavioral biases and focus on their overarching investment goals.

7. Final Insights and Closing Thoughts

In conclusion, the hosts reflect on the valuable lessons learned from Cliff Asness's perspectives, emphasizing the importance of adaptability, open-mindedness, and disciplined investing.

• Cliff Asness [51:22]: “The capital asset pricing model might be one of the best theories in the world. Makes perfect sense... it's a spectacular failure for 75 years everywhere it's been tried.”

• Jack Forehand [56:36]: “This is a great research paper. It's really well written... all of us have to look at it and say, like, what type of conclusion should we draw from it.”

Key Takeaway:
The dynamic nature of financial markets necessitates continuous learning and adaptation. Investors must remain open to new research and methodologies while maintaining a solid foundation in proven investment principles. Cliff's willingness to evolve his thinking in response to new evidence serves as a model for effective, evidence-based investing.
