The Convergence of AI and Stocks: An Author Who Reads the Trends

 

 

2026.07

 

 

Stocks and artificial intelligence are captivating South Korea in 2026. Amids this phenomenon, there is an author who published a book this past April on stock investment secrets using the generative AI “Gemini.” We would like to listen to the story of author Cho Sung-ho, who wrote about Korea’s stock fever and how to establish an investment headquarters by using AI as a personal secretary.

 

 

 

 

Q. The combination of Gemini and stocks seems to epitomize South Korea’s trends in 2026. Could you please introduce yourself and share what inspired you to write this book?

 

I am currently serving as a professor in the Department of AI and Software at Hanshin University. I have spent many years researching and teaching computer science and software, and personally, I also hold a deep interest in economics, psychology, and journalism and mass communication. While these may seem like entirely different fields at first glance, I believe they are profoundly connected in that they ultimately study human choice and judgment.

 

The era when I first learned computer science is a completely different world from today. In particular, I feel that the emergence of generative artificial intelligence represents a shift on par with the birth of the internet. The shock I experienced when I first used ChatGPT remains vivid to this day. I saw immense potential in it, recognizing that it was not merely a tool for answering questions, but a new form of instrument that helps organize thoughts, expand ideas, and assist in decision-making.

 

On a personal note, I have been investing in stocks for several years. In the beginning, I invested based on just a few news articles and experienced significant losses. Since then, I studied by looking into books, lectures, corporate reports, and investment videos, but I realized that studying extensively did not necessarily guarantee better investment performance.

 

What I learned through investing is that the stock market is not simply a game of finding good stocks. It simultaneously requires the patience to wait long enough, the self-control to regulate greed, and the judgment to sell at the appropriate moment. This is why the saying “Buying is a technique, but selling is an art” seems to circulate among investors.

 

In reality, the investment process is more complex than one might think. You have to analyze economic trends, discover promising industries, investigate relevant companies, check financial statements and public disclosures, and analyze charts. It is by no means easy for office workers or students to carry out this entire process consistently.

 

Amidst this, I tried utilizing Google’s Gemini, which is connected to vast amounts of information, and the results were astonishing. Data research and information organization that used to take several hours in the past were accomplished much faster. While the final judgment ultimately rests with the investor, the process of collecting and organizing information could be drastically reduced.

 

Currently, many books on utilizing Gemini in the market focus primarily on introducing its features, while investment books explain the investment techniques themselves. However, there were not many books connecting these two domains. Gemini Stock Investing was born precisely to fill that gap. Through this book, I wanted to introduce readers to methods for collecting investment information more quickly and accurately using Gemini, thereby enabling them to make rational decisions.

 

 

 

 

 

Q. We are curious to know whether you also utilize artificial intelligence for various tasks in your daily life.

 

Artificial intelligence has now become a part of my daily routine. In the past, when I had a question, I would open a Naver or Google search window. Today, I toss my questions to Gemini or ChatGPT first. While searching was a process of finding information, conversing with AI is closer to a process of understanding and organizing information.

 

I also receive immense help when preparing for my lectures. There are many times when I deliberate over how to explain difficult concepts to students. In those moments, I ask the AI for various metaphors and examples. Sometimes, I request it to explain the exact same content customized respectively to the eye levels of an elementary school student, a college student, and an office worker. When I do this, I often discover perspectives that I had not managed to think of myself.

 

I gain a lot of assistance in the process of writing as well. I utilize it when reviewing a book’s table of contents or checking for any lacking aspects from a reader’s standpoint. Although I write the final manuscript myself, it plays the role of an excellent assistant in the process of organizing ideas and reviewing diverse viewpoints.

 

The same applies to stock investing. Previously, in order to analyze a single company, I had to move back and forth between multiple websites to gather data. Now, because artificial intelligence helps with data collection and summarization, I can focus more on the critical judgments. I believe that in the future, people who utilize artificial intelligence effectively will come to possess a greater competitive edge than those who do not.

 

 

 

 

Q. Could you please introduce your book, Gemini Stock Investing, and share what kind of value you hope to deliver to your readers?

 

I believe that a book must be beneficial and, above all, do no harm to its readers.

 

These days, it is easy to come across provocative phrases like “stocks that will rise tenfold,” “life-changing stocks,” or “investment methods that guarantee money.” Of course, I understand that this is an effort to draw readers’ attention amidst a flood of content. However, if it instills excessive expectations and ultimately inflicts losses on someone, I do not believe it qualifies as good information.

 

For that reason, Gemini Stock Investing contains no talk of “stocks skyrocketing by 1000%” or “the next SK Hynix.” Instead, it focuses entirely on helping beginners and everyday investors make more rational decisions.

 

Every individual has a different way of investing. Some people analyze charts, some look into financial statements, and others study the future of industries. This book does not force a specific investment style upon you. Instead, it explains how you can utilize Gemini regardless of the methodology you choose to invest by.

 

To ensure that readers can put it to use immediately, the book includes more than 200 practical, real-world prompts. I have organized questions that can be applied to actual investment processes, covering corporate analysis, industry outlooks, understanding financial statements, analyzing public disclosures, interpreting news, chart analysis, fund and bond trading, and tax-saving strategies.

 

This book does not intend to change your investment philosophy. It is a guide on how to utilize artificial intelligence when you want to double-check before investing based solely on someone else’s recommendation, when making a judgment becomes difficult due to losses, or when you want to comprehend complex corporate information.

 

However, I would like to make one thing absolutely clear. The ultimate responsibility for any investment lies with the investor themselves. While artificial intelligence is an excellent assistant, it is not an entity that prophesies the future. Therefore, the book addresses not only the methods of utilization but also its limitations and precautions.

 

 

 

 

Q. Do you have any plans for writing more books in the future? Please briefly introduce your upcoming plans.

 

I still find great joy in lecturing and writing books. In particular, I feel a deep sense of reward in the process of explaining complex content so that anyone can easily understand it. For that reason, I have put a lot of thought into ensuring that students can easily comprehend the books I have authored so far, such as Easy Learning Operating System, Data Communications and Networking, Introduction to Computer Science, Miracle JAVA Programming, and Miracle Web Programming. I plan to steadily continue writing specialized books in the field of computer science in the future as well.

 

 

While authoring more than ten computer science textbooks over the years, I have always wished to one day write a book that communicates with general readers. The first fruit of that desire was Why Did Steve Jobs Kill Squid Game?, and Gemini Stock Investing is my second general education book. In the future, I would like to continue writing books that allow me to connect with the general public.

 

As an extension of that effort, I have recently completed the manuscript for Gemini Wealth Management, which connects generative artificial intelligence with overall personal finance, including real estate, ETFs, pensions, and taxes, moving beyond just stocks. Moving forward, I intend to steadily write books that easily and practically convey how artificial intelligence is changing our lives and how ordinary people can utilize it.

 

I believe that a good book possesses the power to change a reader’s life for the better, even if only by a fraction, rather than simply transferring knowledge. I wish to continue communicating with readers for a long time through books of such caliber.
