Why is Buffett's investment mainly concentrated in traditional industries?

Buffett's investment companies always put the interests of shareholders first. Buffett always favors those enterprises that are stable in operation, pay attention to integrity and have high dividend returns, so as to avoid stock price fluctuations to the maximum extent and ensure the preservation and appreciation of investment. As for those enterprises that always want to squeeze the blood and sweat of investors through rights issue and additional issuance, they are all turned away.

He wants to invest in enterprises that are easy to understand and have good prospects. Buffett believes that all stocks invested should be self-aware and have good industry prospects. Unfamiliar and unpredictable enterprises are not tempted even if they are hype. During the period of 1969, the whole Wall Street entered the stage of crazy speculation. Faced with a record stock market, Buffett calmly sold all the stocks when the stock rose to 20%.

In 2000, so-called network concept stocks appeared in stock markets all over the world, but Buffett said that he did not understand high technology and would not invest. A year later, global high-tech internet stocks collapsed.
