Profit and loss share the same source, fulfilling the inertia of individual investors The phrase 'profit and loss come from the same source' has been criticized by many people as misleading Wang Chuan said: Profit and loss come from the same source. If you participate in speculative games, after making a big profit, you will definitely be unable to stop and eventually return to the starting point, even losing more. What does this mean? Speculation can lead to negative agreement. But what is speculation? Unclear definition Saying it is equivalent to saying it for nothing Wizards talk about profit and loss sharing: In the field I understand, profits far outweigh losses; In unfamiliar fields, losses far outweigh profits. From the perspective of a wizard, it means there is no profit or loss in this matter, only understanding or not understanding Teacher Wufan said that profit and loss come from the same source: Profit and loss come from the same source because we often speculate Value investing does not have the same source of profit and loss Sha Ge believes that profit and loss are the same source, and what he is talking about should be a single strategy, which has different effects on different market structures, targets, and liquidity environments. Sometimes earn a Maserati, sometimes lose a Maserati It is actually difficult to reproduce the same source of profit and loss. Strictly speaking, it is difficult to establish the concept of profit and loss sharing the same source Because a normal market participant's cognition is constantly evolving, the structure of the market is also constantly evolving, and the target itself is also changing Almost no perfect symmetry occurs, which means that it is difficult for the same source of profit and loss to be fully established in terms of conditions But individual investors are just making profits and losses, and they don't understand why they are making profits and losses, nor do they bother to think deeply about it One exclamation: Profit and loss come from the same source. This is certainly laziness in thinking. But in fact, the reasons for profit and loss almost always have deviations and differences. Because it is difficult to have a neutral strategy over time for different market structures, targets, and liquidity environments In practice, the Aum's Razor principle can completely ignore the perspective of profit and loss from the same source Simply conduct a retrospective analysis of each profit and loss Finally, I don't know which great genius invented the perspective of profit and loss sharing. It has facilitated the inertia of thinking among a large number of retail investors
