Today, I saw a friend on Twitter saying that ByteDance is a doomsday options betting dog, because several successful times of luck have achieved high returns and landed. Actually, it can be understood that anyone who sees an ordinary person suddenly become rich and go against the tide like the protagonist of Shuangwen would feel a little unwilling. Why? I always want to find a reason, preferably something wrong, so that I can feel much more comfortable in my heart. High odds betting on dogs is a good reason, whether it's the former Liangzi or Wynn, they are both very popular, and then there is no such person found. But after reading his article, I think there may still be some bias. After all, the fact that one can discover Alpha from small things in life, conduct investment research with reason and evidence, find support, and then invest is quite different from the real doomsday gambling dog I know. When the principal is small, it is necessary to use leverage, but those who can rely on leverage for a long time and survive must have a few brushes, not purely relying on luck. Many of my financially independent friends around me have also seized an opportunity and leveraged themselves to make the first few buckets of gold, then changed their way of thinking and started to steadily move forward. Unless unexpected, they will not fall back to their original level. Learning to accept and acknowledge the strengths of others, and then finding areas worth learning from, is more helpful than simply labeling others as reasons for their success. His method of assessing the breadth of fund holdings has valuable reference value for me and is quite good.
