In recent years, especially during and after the pandemic period, the structure of financial markets, the habits/profiles of stock market investors and the speed of information flow have undergone a radical transformation. One of the most visible reasons for this transformation was undoubtedly social media platforms. Platforms such as X, Telegram, Youtube, Discord etc. have completely changed the way investors follow the market, follow the news, interact with each other and even act collectively. Especially traders who make intraday transactions are among those who benefit most from this transformation.
In fact, the connection between social media and financial markets started and continued under the influence of forums from the early 2000s to the 2012s. In 2012 and later, now known as Many new investors were attracted to the market, especially with the impact of public offerings, and especially this new audience directly preferred social media instead of traditional media or analysis reports as a source of information. Financial communities on X, which we call "FinTwit" today, bring together individual users, fund managers, economists and journalists with thousands of followers.
When we look at it; Today, X is still the platform where financial news spreads the fastest. A tweet sent by a company executive can cause 5-10 percent movements in the stock price within minutes. This effect also applies to individual accounts: users who have reached a large enough follower base can direct the market, at least in stocks with a certain depth, with the messages they send. The algorithmic structure of
On YouTube, long-term analysis channels reach large audiences. However, on both platforms, unrealistic expectations and inadequate risk warnings pose a serious problem for investors. Telegram and Discord are places where closed/open groups act for marketing and manipulation in crypto and other exchanges. The impact of social media on intraday trading operates through several different channels:
Speed of information dissemination: A news that may take minutes or hours in traditional media can reach hundreds of thousands of people in seconds in X. The investor who receives the first information can take a position before the price is adjusted.
Emotions: The intensity of sharing in the same direction creates a collective psychological tendency. This makes knowing what the majority thinks more important than individual decisions.
Herd psychology: People tend to do what the crowd does most of the time. Social media manages to make this trend instantaneous and visible. Investors who see that a particular stock/fund or a different investment instrument is active/popular prefer to get on that train without doing their own research.
Algorithmic triggers: High-frequency trading (HFT) algorithms make automatic buying and selling decisions by feeding social media sentiment data. This can cause a small fluctuation on social media to turn into a big movement in the market. Rapidly spreading, unverified, and unknown-origin news flows can lead to very harsh movements on financial instruments.
The impact of social media on transactions in financial markets is not only negative but also has some positive effects.
Information accessibility: Small investors can now more easily access information that was once only available to institutional investors. Social media makes this data accessible, at least partially, to analyses, educational content and instant news.
Increased transparency: Companies and managers can now communicate directly to their stakeholders via social media. Although this communication can be used for good purposes, there are managers who use it for different purposes today. There are new resources to detect insider trading, but the intervention of authorities in this regard is still debatable.
The power of the community: As in the case of GameStop, individual investors can collectively take positions against large institutional players. This has the potential to change the power imbalance in the market to some extent. However, making timing mistakes is still a big problem for many investors.
However, the negative effects of social media on intraday trading are also considerable:
Increase in volatility: When many investors move in the same direction at the same time, it causes sudden and sharp fluctuations in prices. This means unpredictability, especially for intraday traders. However, many investors who are fascinated by volatility may open wrong positions.
Pump and dump: Some groups aggressively raise a stock, then share it through certain accounts on social media, continue to artificially increase the price, and then sell their own positions, leaving other investors to the inevitable end. Such manipulations, which are especially common on the crypto side, have increased in traditional markets as well as social media.
Misleading information: Unverified rumors, false financial data or deliberately produced disinformation can reach many investors within seconds and cause them to make wrong decisions.
Overconfidence and FOMO: Investors who are exposed to constant profit stories of accounts seeking interaction without even a serious investment on social media are stuck with unrealistic expectations. FOMO (fear of missing out) unfortunately leads to the abandonment of disciplined trading strategies.
Addiction and mental health: Constant notifications, instant chart tracking and community pressure can cause anxiety, depression and even addiction-like behavior patterns in many investors. Remember, the stock market is not gambling, but it can be turned into gambling by the people who trade. It's up to you which side you choose.
The US Securities and Exchange Commission (SEC) has taken various steps against social media-driven market manipulations. Following the GameStop incident, reports reviewing the market structure were published; Increasing short position reporting transparency was brought to the agenda. Posts of social media influencers that constitute "financial advice" are being re-evaluated in terms of securities law. Accounts that offer "special" advice, especially through paid subscription models, may face charges of unregistered investment advice. In the European Union, monitoring of manipulative content on social media has been tightened within the scope of the Market Abuse Regulation (MAR).
As the power of social media inevitably increases, a few basic principles for a successful day trader stand out:
Diversify the source of information. Be sure to verify news coming from social media with basic data and traditional sources.
Follow your data and strategies, not your emotions. When the wave of excitement on social media forces you to make a decision, stick to your own strategy.
Never neglect risk management. Stop-loss levels and position size must be maintained despite all the emotions and news flow.
Be wary of the speed of algorithms. Information on social media may already be reflected in prices by algorithms before you read it and convert it into transactions, so be sure to check the information on prices before opening a transaction.
Manage your timing well and control your Position size. Heavy social media traffic before market opening and closing contains both opportunity and danger; In these cases, it may be wise to review position sizes.
The impact of social media on financial markets will increase further in the coming years. Artificial intelligence-supported sentiment analysis, real-time news processing and algorithmic trading strategies fed directly from social media continue to become widespread. X, Discord servers and even closed Telegram groups are now part of the information flow around the world. Whether the regulatory framework can keep up with this pace and take the necessary measures in a timely manner remains a critical question and problem in terms of market integrity.
Social media has irreversibly changed the nature of intraday trading. It democratized access to information, made community power visible, and increased market participation. But it also brought volatility, risk of manipulation and psychological pressure. A successful intraday trader must learn to position social media in this new environment not as a weapon, but as a tool that must be used carefully, and to fight against manipulators who use social media as a weapon.
