Zhang Yao is a senior investor whose approach is especially useful for individual investors. The following ten points distill years of his experience.

  1. Any company held as a major position must be within your circle of competence.
  2. Set reasonable return expectations—typically 15% annualized, or a doubling every five years.
  3. Do not let price movements in companies outside your competence influence your emotions or trades.
  4. Do not start with a prediction. Prepare a response for each plausible outcome.
  5. When markets are depressed and a company is undervalued, own as many shares as possible. As markets become euphoric, reduce your position gradually.
  6. Valuation matters. Even a wonderful company must be reasonably priced. Avoid excessive valuations, insist on a margin of safety, and minimize permanent loss.
  7. Follow the macroeconomy as needed, but do not let macroeconomic fluctuations determine decisions about a target company.
  8. Study industries and companies over a long horizon, focusing on competitive advantage.
  9. Think of the number of shares you own multiplied by earnings per share as your profit, and dividends received as your cash flow—think like an owner.
  10. Make decisions as simple and relaxed as possible. Invest only in familiar companies whose quality you can assess quickly; choosing one or two companies every year or two is enough.
