Episode notes
Constant in Finance
- In finance and investing, people demand a return for uncertainty, and this principle remains constant.
- However, implementation methods can change as financial laws evolve, unlike the unchanging laws of physics.
Evolving Models
- Financial models, like those in physics, evolve and improve our understanding.
- All models are imperfect representations of reality and should be viewed with skepticism.
Model Skepticism
- Approach financial models with healthy skepticism, considering their potential flaws.
- Prioritize building robust solutions that remain effective even if the model proves incorrect.
