I read Article 19 of Schwarzman: My Experiences and Lessons: "Don't lose money!! objectively assess the risk of each opportunity." ”
We often can't know what risk is, or even just know the word "risk". No one wants to do money-losing trading, but losses are indeed everywhere, which is worth thinking about how to eliminate losses. Can it be determined that the reason for losing money is that they do not fully understand the risks, so they will lose money. If you don't realize the possibility of losing money, or you can't find a reason for it afterwards, it means that you don't know what the risk really is.
I think risk is the way you are prepared for the various outcomes that may arise when you do something, that is, the response to the different outcomes. This way you can make sure that things are out of your control. Don't get out of control and have no solution. That's the risk factor. Don't lose money is the golden rule of investment, you can not make money, but you can't lose money, this is because the capital itself contains the concept of time, if you lose money, not only the loss is the time you invested in this period, but the time accumulated by the principal is also put in, which is the most deadly, time is the most precious for everyone, especially people with huge capital.
Therefore, guarding the safety of capital is the most important compulsory course for investment.
