Vous souhaitez investir en bourse? Débutants ou investisseurs chevronnés, voici une liste de 22 adages financiers qu’il faut avoir entendu au moins une fois.
Si vous ne comprenez pas l’une d’entre elles, n’hésitez pas à poser des questions dans les commentaires.
J’aime tout particulièrement les #3, #4,#5 et #17.
1. For all long-term investors, there is only one objective— “maximum total return after taxes.”
2. Achieving a good record takes much study and work, and is a lot harder than most people think.
3. It is impossible to produce a superior performance unless you do something different from the majority.
4. The time of maximum pessimism is the best time to buy, and the time of maximum optimism is the best time to sell.
5. To put “Maxim 4″ in somewhat different terms, in the stock market the only way to get a bargain is to buy what most investors are selling.
6. To buy when others are despondently selling and to sell when others are greedily buying requires the greatest fortitude, even while offering the greatest reward.
7. Bear markets have always been temporary. Share prices turn upward from one to twelve months before the bottom of the business cycle.
8. If a particular industry or type of security becomes popular with investors, that popularity will always prove temporary and, when lost, won’t return for many years
9. In the long run, the stock market indexes fluctuate around the long-term upward trend of earnings per share.
10. In free-enterprise nations, the earnings on stock market indexes fluctuate around the replacement book value of the share of the index.
11. If you buy the same securities as other people, you will have the same results as other people.
12. The time to buy a stock is when the short-term owners have finished their selling, and the time to sell a stock is often when short-term owners have finished their buying
13. Share prices fluctuate much more widely than values. Therefore, index funds will never produce the best total return performance
14. Too many investors focus on “outlook” and “trends.” Therefore, more profit is made by focusing on value.
15. If you search worldwide, you will find more bargains and better bargains than by studying only one nation. Also, you gain the safety of diversification.
16. The fluctuation of share prices is roughly proportional to the square-root of the price.
17. The time to sell an asset is when you have found a much better bargain to replace it.
18. When any method for selecting stocks becomes popular, then switch to unpopular methods. As has been suggested in “Maxim 3,” too many investors can spoil any share-selection method or any market-timing formula.
19. Never adopt permanently any type of asset or any selection method. Try to stay flexible, open-minded and skeptical. Long-term top results are achieved only by changing from popular to unpopular the types of securities you favor and your methods of selection.
20. The skill factor in selection is largest for the common-stock part of your investments.
21. The best performance is produced by a person, not a committee
22. If you begin with prayer, you can think more clearly and make fewer stupid mistakes
