    How to hold stocks for more than five years?

      There are very few investors who can really hold for more than 5 years. How can we firmly hold stocks for more than 5 years?   Let me talk about my personal experience:   When we have a correct understanding of long-term holding stocks, we must first do: First: make a grand vow   ”We want to hold it for a long time, even for more than five years!” Just like when we all made up our minds when we took the entrance examination, we will not give up until we enter the university. My experience is that the bigger the vow, the easier it is to carry it out. When we want…

    “Odd” and “Even” jointly scan the world   On July 11, 2022, a heavy rain hit Taiyuan City, Shanxi Province. Affected by heavy rainfall, many buses in Taiyuan City were rerouted and suspended.

    From soldier to scientist

    The Amazon rainforest spans 8 countries – Brazil, Colombia, Peru, Venezuela, Ecuador, Bolivia, Guyana and Suriname. It occupies half of the world’s rainforest area and is the largest and most species-rich tropical rainforest in the world.   Deep in the Colombian Amazon rainforest, dozens of sweaty workers navigate a maze of kapok and rubber trees. Armed with machetes, they hacked back and forth through the thick vines, accomplishing their mission with purpose — cataloging and protecting endangered species. Years ago, the guerrillas might have been tracking enemy soldiers, or preparing to kidnap a political prisoner. Now, their targets are even more elusive: giant otters, nimble brown spider monkeys, very eerie Dracula…

    Explaining the Market Crash Mechanism with Complexity Science

      Why did Michael Mobson praise Didier Solnet’s “Why the Stock Market Crashed” in “Devil’s Investing” as “far-reaching and never tire of reading”? Because this book can be seen as a story, a scientific story about how to borrow the most cutting-edge and complex concepts in modern science to understand financial crashes, namely the theory of complex systems and critical phenomena.   Solnet was a pioneer in studying market bubbles. In financial research, he introduced the concept of “log-periodic power-law singularity”, which is a not easy to understand phrase. In short, log periodicity refers to the hierarchy of trading unit sizes and the result of non-linear interactions between trend followers and value…
