With the passage of time, the "noise" of the stock market is also escalating. TV commentators, financial writers, analysts and market strategists compete with each other and are jealous of each other in order to attract the attention of investors. At the same time, individual investors are addicted to chat rooms and message boards, seduced by suspicious and even misleading investment techniques. But even so, investors are finding it increasingly difficult to make money in the stock market. Some investors are difficult to sustain because of repeated defeats and battles. Share prices soar for no reason, and then plummet, leaving retail investors who invest in their children's education and retirement frightened and frightened. There seems to be no rhythm or reason in this market, only stupidity and madness.

Warren Buffett's investment wisdom and skill advice completely transcended the madness of the market. In an environment that seems to favour speculators rather than investors, time has shown time and again that Warren Buffett's investment advice has become a haven for millions of lossmaking investors.

For years, critics have argued that Warren Buffett's personalized approach to investment cannot be replicated. I don't agree that Buffett's investment approach is unique in a market that emphasizes frenzied buying and selling stocks, and Buffett's "buy and hold" investment philosophy is not unusual. On the contrary, I do have doubts about those who say that only Buffett can fulfill the "Buffett investment purpose".

"the Nature of Investment: Buffett's 12 Investment purposes" shows Buffett's complete 12 investment purposes, so that all investors, whether retail investors or professional investors, can accept these methods and use them for my own use. At the same time, Buffett's ideas are successfully applied to the "new economy".

The author Robert Hagstrom is an expert on Buffett's investment ideas and strategies. "the Nature of Investment: Buffett's 12 Investment purposes" draws on the best-selling books "Buffett's way" and "Buffett's portfolio" on how to choose companies and stocks. And how to manage Berkshire's portfolio strategy.
