Are Japanese companies engaging in technological innovation, productivity improvement, and market development?
There may be some companies that continue to grow sustainably, but overall, it seems that there are many that do not.
Therefore, there seems to be no intrinsic factors for the rise in stock prices.
However, other factors, such as investors' (speculative) actions, are separate from this and may become factors that push up stock prices.
However, it is unlikely to have the momentum of a US company that continues to grow exponentially like an index etf.

It seems to greatly depend on who understands what and to what extent.
Even if all existing successful people were like that, would all people other than those existing successful people, those who will succeed in the future, and those who will fail in the future achieve success by acting in the same way?
Moreover, it does not seem to be related that someone understands something about the company and the company's performance or stock price.
However, from the perspective of the scramble for a limited number of shares, if many people are interested and actually acquire shares, the apparent value will increase.
