Buffett’s Rules for Stock Investing

Buying stocks is like buying businesses.

Buffett Quote: “You only have to do a very few things right in your life so long as you don’t do too many things wrong.”

  • When you buy a share, you become part owner of that business.

  • Evaluate the purchase of one share as you would if you were to buy the entire business.

  • Do not be concerned by short-term market price fluctuations, or volatility.

  • If you were buying a private business, you wouldn’t be interested in day-to-day valuations of your business.

Buffett’s Rules for Stock Investing

Stay within your circle of competence.

Buffett Quote: “Risk comes from not knowing what you’re doing.”

  • Do you understand the business, its core products and services, and the industry?

  • Can you see out 5, 10, 15 years and have a reasonable probability of gauging the future correctly in terms of the company’s earning power and competitive position?

  • You must have some idea of how the industry will develop and where the company will stand within its industry.

  • You don’t have to invest in anything you don’t like or deem too difficult.
