I borrowed a book called “The Loser's Game” at the library and read it. Written by Charles Ellis, translated by Kage Yuji and Kage Fusako. According to this book, people with poor abilities in tennis matches will get tired and lose if they continue to make shots that earn points. That's not it. An example was introduced where by continuing a rally, you wait for your opponent to get sick and then move to value in a match. When I slide this to individual investors, it was described about the splendor of the so-called dollar cost averaging method, where individual investors readily invest a fixed amount at a fixed timing regardless of how high or low the market price is. This time, too, it will be a factor in changes in market prices, but I would like to keep accumulating money without changing my investment strategy.
