Reflecting changing industry conditions and updating key issues

To invest in stocks, you need to understand the business model of a company and how it makes money, and analyze its financial data to see exactly how much money it has made.
However, this task is not only difficult and tedious for amateur investors who have other jobs, but also for professionals whose main job is investing.
It costs a lot of money to get help.
Therefore, the most realistic and efficient way is to select a good book, read it, and utilize it.

The "2025 Listed Company Industry Map" provides simple yet concrete, key data.
We created 25 industry baskets, and installed partitions in each basket according to the characteristics of the company.

Industry History as Seen Through Stock Indices
Energy transition and aging populations will become increasingly important in the future.

Part 1 looked at the history of the Korean stock market through stock indices.
The Korean stock market began with 12 companies in 1956 and grew to approximately 2,400 companies by 2024.
The book examines the ups and downs of industries from 2000 to 2024, analyzing interest rates, oil prices, economic growth rates, politics, and leading industries that influence the KOSPI index.


For example, when the global financial crisis broke out in 2008, the KOSPI index plummeted from 1,700 points to 1,100 points, but liquidity was supplied thereafter, and a liquidity boom unfolded from 2009 to 2011, leading to a craze for 'cha·hwa·jeong (automobiles, chemicals, and oil refining).
The period after 2023 will be the era of artificial intelligence, symbolized by ChatGPT.
The author presented ‘energy transition’ and ‘aging’ as paradigms that will have a major impact in the future.

Four themes to watch, from energy to defense
Seize the opportunity to enjoy growth together

The four themes to watch in 2025 were selected as 'energy, bio, beauty, and defense industry.'
What they have in common is that they are recording differential changes and rapid growth.
Since the 2000s, the transition to 'decarbonized and eco-friendly' energy has been implemented, but the brakes have been applied due to unstable power generation and power grid shortages.
Therefore, there are opportunities for companies involved in power grid expansion and nuclear power generation.
Biotech companies have strengths in the bioplatform sector, which enables accurate and rapid drug delivery, and the opportunity has grown further with the US decision to sanction Chinese biotech companies under the Biosecurity Act.


K-beauty is gaining popularity in North America and Japan as a result of collaborations between indie brands, ODMs, and distribution platforms, and cosmetic medical devices such as botox, fillers, lifting, and home beauty devices are expanding their base to the global market thanks to social media.
Defense industry companies are experiencing a surge in export orders amid the "new Cold War-deglobalization" atmosphere, fueled by the Russia-Ukraine war and the Israeli conflict.
By focusing on companies that are leading the way in these fields, you can create opportunities to share in their growth.

Analysis of 25 industries and holding companies
Added PBR band, a useful indicator for investment.

In Part 3, all stocks of approximately 2,400 listed companies are classified into 25 industries, and the companies within each industry are linked by "business field" and "supply chain," and the characteristics and trends of the industries are briefly explained.

Finally, the landlord was added.

In this book, we have condensed the sectors from 91 to 89 to more clearly organize the companies within them.
The stock market is constantly changing due to frequent corporate mergers and acquisitions, delistings, and new listings.
A company's business model may change, and its industry may change.
The book reflects the changing landscape of the industry and updates key issues.


It's good to just group together the industry maps for reference
Special Appendix: "Stock Discovery Chain Map"

The mind maps included up to the 2021 edition were well-received for their advantage of showing the overall flow.
However, some pointed out that it was difficult to decipher due to the complex branch shapes, irregular lines, and small letters.
So, starting with the 2023 edition, we are producing industry maps in a flow diagram format that is as simple as possible to improve visibility and readability.
Just by looking at the industry map, categorized by industry-sector-subcategory, you can grasp the big picture of the manufacturing process and ecosystem and identify companies that are competing while conducting equal business.

It is not easy for individual investors who lack professional knowledge to classify industries and analyze companies based on their own criteria.
It is even more difficult to grasp the stock market at a glance, predict the future, and find good stocks.
Some people suffer huge losses by investing solely based on popular YouTube channels, blogs, stock reading rooms, and stock news.
However, if you use this book, which comprehensively examines all stock market sectors, as a stock-discovery navigator, it will establish a standard for viewing the market and help improve your investment performance.
