The explosion of semiconductors and storage has caused anxiety and unease among many brothers. Afraid of stepping into the air and afraid of chasing high. Xiao Deng vs Lao Deng, they were arguing fiercely. Let me tell you, brothers, the core still needs to have its own system and mode. Think about the US stock market. Currently, technology stocks are booming, but Buffett is holding a handful of cash and waiting for a decline. From a historical perspective, Ba Lao has never heavily invested in technology stocks. When he bought apples, they were still considered consumer stocks In the last round of bull market in science and technology stocks, Sister Mu made a huge profit and became a popular Crispy fried chicken. The interim return rate far exceeds Buffett's. But as technology stocks receded, Buffett's returns gradually surpassed hers again. In short, not buying technology stocks is definitely not wrong, it does not mean that all sectors can make long-term profits. As long as you have your own system and mode, there is no problem. … After folding the armor above, I must say: Most of the old investors who buy stocks are not affiliated with Buffett. They are the old Deng with outdated thinking, immersion in the previous era, and stubbornness. When they can't hold on and sell old stocks on a large scale and buy small stocks... it's time to reach the top. On the contrary If they persist in not selling old stocks, then small stocks will continue to rise. Rise until they can no longer hold on. This is the stock market. After you get old (referring to thinking and cognition), wealth will be taken away.
