He said that although he initially intended to use them only as a reference, he found himself reaching for the buy button as similar posts were repeated. He confessed, "I don't even know who wrote them, but as I keep reading, it feels like there is information that only I don't know. " The influence of online communities and social networking services (SNS) on stock investing is growing.
Stock discussion forums, YouTube comments, open chat rooms, and investment bulletin boards have become channels for individual investors to obtain information. However, concerns are being raised that posts with unclear sources and exaggerated predictions are mixed in, potentially clouding investment judgment. Confident posts.
The Dilemma of Pressing the 'Buy Button' Posts in stock discussion forums are short and definitive. They follow the pattern of "Good news is coming," "Market manipulators are accumulating," or "If you don't buy today, it's too late. " While there are posts analyzing corporate earnings or disclosures, there are also many baseless rumors.

The responsibility for anonymous posts is unclear; even if they are wrong, one can simply delete the post. These posts have an even stronger impact on working investors. This is because it is difficult to read corporate reports or disclosures in detail during market hours.

Mr. B, a working professional in his 40s, lamented, "I don't have time to read all the disclosures, so I end up looking at posts that others have summarized in the discussion forums.
" He added, "When I look back later, there were many claims that hadn't been fact-checked, but at the time, I was swept up in the atmosphere. " The problem is that the more posts one reads, the more certain one becomes. When multiple people write the same argument, it feels like the truth.
When dissenting opinions arise, they are sometimes labeled as "short-selling paid trolls" or "intimidation posts. " Investors believe they are viewing diverse information, but in reality, they may repeatedly encounter only arguments that follow the same direction. **Impromptu Buying Fueled by Mobile Trading** The influence of online posts is also linked to the mobile trading environment.
According to data on "Mobile Trading by Individual Investors in the Stock Market" released by the Korea Capital Market Institute in 2022, an analysis of the trading records of 134,000 domestic individual investors from March to October 2020 revealed that mobile investors had higher trading turnover and a higher proportion of intraday trading compared to users of other trading platforms. They also showed a strong tendency to buy stocks that had surged in price, while their investment performance was found to be relatively poor. Mobile trading offers high accessibility.

He expressed regret, saying, "At first, I intended to just look at stocks of interest, but as I read the posts, I find myself immediately going to the order window," and added, "There have even been times when I only thought about why I bought it after I had already done so. " When stock prices rise, stock discussion forums become more heated.
The more a stock surges, the more posts there are, and the more posts there are, the more investors join. However, the atmosphere changes rapidly after the price drops.
Posts saying "just hold on" and "I was tricked" become mixed together, making it easy for investors to miss their selling criteria. You must be more cautious of information from "trading rooms" and social media.

It also pointed out that buying stocks solely because the price has surged without any specific positive news is highly likely to lead to a subsequent sharp decline.

According to an analysis of data submitted by the Financial Supervisory Service to the office of Representative Heo Young of the National Assembly's Political Affairs Committee last October, 5,103 complaints related to unregistered investment advisory businesses were received between 2020 and 2024.
Of these, 843 cases were referred for investigation due to illegal activities. Complaints regarding refunds and contract cancellations were the most frequent, and reports concerning unregistered investment advisory services and false or exaggerated advertising were also included.

They must also distinguish between mere forecasts and content that has been confirmed as fact.
Ultimately, office worker Mr. B recently reduced the time he spends checking stock discussion forums.
He said, "There are good posts, but after reading them, I feel like I have to do something," adding, "These days, I try to check the public disclosures first rather than buying immediately after reading a post. " The Financial Services Commission advised, "Do not be misled by baseless information and rumors, and carefully verify the source and basis of the information.
" It also stated that one should check on the Financial Supervisory Service's financial consumer information portal, 'FINE,' whether the operator of a 'leading room' is an investment advisor registered with the Financial Services Commission.
