On the Persistence of Growth and Value Stocks

While analysts underwrite high growth for companies that have grown quickly and slow growth for companies that have grown slowly in the past, a large body of evidence demonstrates that reversion to the mean of both positive and negative abnormal earnings growth is the norm.

Can ChatGPT Improve Your Stock Picks?

One use of the NLP (natural language processing) features of ChatGPT is to search out patterns in the immense amounts of news, data and other sources of information about specific stocks, and then efficiently convert them into summaries valuable for all types of investors.  Can this be accomplished with useful results?

Band of Brothers Attacking Short Sellers: Game Stop for Hedge Funds

Advisors and investors should be aware that fund families that invest systematically have found ways to incorporate the research findings on the limits to arbitrage and the evolving changes we have discussed to improve returns over those of a pure index replication strategy.

Professional Athletes and Money Skills

Trend to Passive Investing Negatively Affecting Active Funds

While the evidence makes clear that active management is a loser’s game (one that it is possible to win but so unlikely you should not try), we don’t want active managers to disappear.

Fifty Shades of Grey Swans: Timeless Risks with a Modern Twist

The world is complex and ever-changing; news travels at warp speed, events happen fast, and popular narratives can distract and mislead us.

Good risk management can be described as a balancing act that employs the first principles of investing, lessons from history, behavioral psychology, a little math, and even our imagination in service of our objective: to detect and defend against the risks we can foresee and fortify our portfolios against those we cannot. In short: we need informed creativity, not calculation.
