How I Invest with David Weisburd

Alec Litowitz argues adaptability beats certainty in investing

E417: $20B Investor on Risk, Uncertainty & Adaptability

As AI and algorithms make information faster but not necessarily better, Litowitz explains how investors can make decisions without mistaking confidence for knowledge.

3 key takeaways
  1. 1Investors must separate measurable risk from uncertainty, where probabilities and reliable models may not exist.
  2. 2Strong opinions become useful when held provisionally, tested against missing information, and separated from personal identity.
  3. 3Adaptable institutions prioritize exceptional people, recoverable experiments, feedback, and learning over individual trade-making or vindication.

Don't miss

Litowitz explains why separating decisions from identity lets investors run recoverable experiments, revise strong opinions, and learn without treating error as personal defeat.

The brief

Alec Litowitz opens with the distinction between measurable risk and uncertainty, using early convertible-arbitrage and merger investments—including an AbbVie and Shire failure—to show where models stop helping.

The founder of Magnetar argues that good decisions require provisional beliefs, Bayesian updating, and a willingness to ask what trusted information or missing perspective could overturn a thesis.

Litowitz treats culture as an investment system: hire exceptional people, demand high standards, separate identity from decisions, and reward learning rather than personal vindication.

The conversation extends that framework to AI and algorithms, which can amplify emotional extremes or produce average answers unless used to challenge assumptions and expand possibilities.

His closing advice returns to beginner’s mind: uncertainty is not merely a threat, and fear of mistakes can prevent the experimentation that makes adaptability possible.
