ChatGPT and other conversational bots: useful, but not stock market predictors ChatGPT and other conversational bots have revolutionized the way we interact with technology, providing quick answers, detailed explanations about science, history, or technology, creative content generation, programming assistance, data analysis, translation, and even advice on recipes, study routines, or exercise. Their versatility has led more people to turn to these tools for everyday questions or even personal guidance. One of the most notable recent uses is ChatGPT as a digital "therapist," especially among Generation Z. The accessibility and low monthly cost have made AI an alternative for those seeking emotional support at any hour. However, this use carries significant risks: artificial intelligence cannot and should not replace mental health professionals. Recent cases have shown that blindly following a chatbot's advice can have serious health consequences. The same principle of caution applies to the financial realm. According to a Reuters report based on a survey by eToro of 11,000 retail investors, 13% of individual investors already use AI tools like ChatGPT to make investment decisions. Many prefer to consult these bots rather than human experts, using their analyses to decide their stock market moves. Jeremy Leung, a former UBS analyst, acknowledges that ChatGPT allows him to replicate many of the workflows he previously performed with costly financial data services. Examples like the Finder experiment, which asked ChatGPT to select high-quality stocks and achieved a 55% growth in its portfolio, seem to demonstrate the potential of AI in investing. However, these results should be analyzed with caution. The market context, with indices like the S&P 500 at historic highs, favors almost any stock selection strategy to appear successful. As Dan Moczulski, CEO of eToro in the UK, warns, the danger lies in treating generic models like ChatGPT or Gemini as infallible oracles: they can make mistakes, misinterpret data, and rely too heavily on past trends to predict the future. In conclusion, while artificial intelligence is a powerful and versatile tool, it does not have the ability to foresee stock market behavior. Using it as a complement can be helpful, but it should never replace professional judgment or critical analysis.
