Five Simple Investing Lessons From The Intelligent Investor
Benjamin Graham’s book teaches people to think calmly about investing.
A stock is a small piece of a company, so investors should study the company behind it.
They should not buy only because a price is rising.
Graham’s imaginary partner, Mr Market, may offer cheerful or worried prices each day.
Investors can ignore those changing offers and focus on the business.
A margin of safety means leaving room for mistakes by avoiding prices that seem too high.
Spreading money across investments can reduce dependence on one company, but it cannot remove every risk.
People should choose an investing approach they can understand and maintain.
Treat a share as ownership in a business, not merely a rising price.
Evaluate a company’s earnings, loans, customers and financial health before investing.
View market prices as changing offers rather than instructions to buy or sell.
Use a margin of safety by paying less than your estimated business value, while recognizing losses remain possible.
Diversify investments and choose an approach that fits your time, knowledge and willingness to research.
