It is said that an investment motto circulating on Wall Street is called "Cut off losses and let profits run." This sentence has a profound connotation, so profound that it can't be understood in a few words, so profound that it takes several years or even more than ten years or even longer to fully understand it. This sentence is purely ostentation, in fact, I don't know what its profound connotation is. However, which one of my words is not to show off? The so-called speaker does not know, I also talk nonsense. )
