30Office worker A has recently been checking stock discussion forums more often than a stock app. A says there have been many people around them saying that “everything will go up,” and that they initially intended only to check. When searching for stocks of interest, posts such as “it’s just starting,” “institutions are accumulating,” and “it’s going to hit the upper limit” reportedly caught their eye first. A initially intended only to use the posts as a reference. When similar content was repeated, A pressed the buy button. A said they did not know who had written the posts. A said, “The more I keep reading, the more it feels as if there is information that only I do not know.” A explained that this actually changed their investment behavior. Stock discussion forums, YouTube comments, open chat rooms, and investment bulletin boards are being used by individual investors as channels for obtaining information. Cases in which the same wording is repeated across multiple channels are increasing. The posts contain a mix of claims whose sources are unclear and exaggerated forecasts. Some posts are reportedly clouding individual investors’ judgment. Individual investors are increasingly making trading decisions after viewing posts.
