A re-investment manual from a renowned expert in the field, who has achieved the highest number of recommendations on Naver's Stock Chart Research Center, a Naver stock cafe with over 330,000 members.
In this book, the author advises individual investors who still dream of striking it rich with "one good stock" despite over 90% of them actually suffering losses to change their concept of investment itself.
It is emphasized that in order to survive in the stock market, it is necessary to understand the principles and risks of the stock market.

The author asserts that while many people want to find a way to profit regardless of the market's trends, there is no way to go against the market's flow and always win.
It is also argued that when the principle or focus of all investment is on loss management, paradoxically the market rewards us with 'profits'.
Regarding the flashy techniques that individual investors cling to, he acknowledges that any trading technique can lead to losses, and repeatedly emphasizes that only by preparing countermeasures can one truly become a winner in the stock market.

The stock market is a battlefield where many unexpected variables exist and all kinds of 'operations' are in play.
Because it is a place where blood money flows.
In this scary market, it is difficult to survive, let alone make money, with the naive idea that you can make money by simply buying a certain stock at a certain price and selling it at a certain price. That is the stock market.
---From the "Prologue"

While there are reasonable principles or rules for making money in stocks, there is no absolute way to always make money without losing 100% of your money.
There's only one thing you need to change to survive in the stock market.
Realize that the uncertainty and risk of the stock market are absolutely not something you can avoid no matter how hard you try, and learn how to naturally accept and deal with them. --- From "Ignorance and Misunderstanding About Stock Market Risk"

The only standard by which ants, lacking information, can determine the truth is the movement of the 'price' itself.
Because ultimately, all information is reflected in the price. --- From "Trading Habits That Underestimate the Movement of the Stock Price Itself"

Trying to find the perfect trading strategy or technique using a combination of technical indicators is no different from trying to create a kind of "perpetual motion machine."
Why are technical indicators inherently imperfect? ​​The reason is simple.
Technical indicators are simply shadows of stock prices. --- "Blindly following technical indicators or trading techniques."

The reason I emphasize losing money rather than making money is because losses can be fatal if not properly managed.
The most important reason why loss management is absolutely necessary is the asymmetry of profit and loss.
The asymmetry of profit and loss is the principle that, as the scale of loss increases, the return must be greater than the loss rate to recover it. --- From "The First Step to Successful Investment"

The most important thing in stock trading is psychology.
No matter how good your trading skills are or how firm your principles are, if you're afraid of losing too much money when you actually need to buy, you won't be able to stick to your principles.
Therefore, it is important to set a loss limit that allows you to trade comfortably without being swayed by your psychology.
---From "The Power of the 2% Rule"

It is not the technique or the stock that gives you profit, but the 'market'.
When your account continues to grow, you often feel like you're brilliant at picking stocks or using your trading techniques. The truth is, it's because the market is rising.
There is absolutely no other reason.
Therefore, it is much more important to have a standard for reading market trends before resorting to minor stock selection or trading techniques. --- From "The Second Button to Successful Investment"

The scariest and most fascinating attribute of stock price movements is this 'trend'.
You never know how long a rising stock price will continue to rise, and you never know how long a falling stock price will continue to fall.
That's why your habit of buying in the 'falling zone' is destined to fail someday.
Therefore, the timing for you to buy is not when the index continues to fall and the absolute price continues to decrease, but when the index continues to rise and the price continues to increase. --- From "How to Define an Uptrend"

The principle of all stock trading is to buy when the price breaks through a meaningful resistance line or rebounds near a support line, and sell when the price breaks through a meaningful support line and falls or fails to break through the resistance line.
This is the core principle of trading.
When a stock reaches a support or resistance line, no one knows whether the price will move up or down.
The odds are 50/50.
Nevertheless, the reason for trading at support and resistance lines is because these points have a large profit-loss ratio. --- From "Stock Price Properties - Support and Resistance"

Whether a stock is cheap or expensive is not an absolute concept but a relative one.
If the stock price rises for 5 consecutive days and rises again the next day, then yesterday's price was cheap. If the stock price falls for 50 consecutive days, not just 5, and falls again the next day, then yesterday's price was expensive.
A section that breaks through the box is considered a "cheap spot" because it provides a reasonable basis for the stock price to rise. --- From "The Advantages and Common Misconceptions of Trend-Following Trading"

To rush in solely relying on flashy techniques without any concept of risk management, money management, or market judgment is as reckless as jumping into a minefield teeming with enemy troops, relying solely on your own excellent marksmanship, when the tide of battle has completely turned and your allies are in a state of disarray while retreating.
Only when all these conditions are meticulously met will the technique you have been so obsessed with truly shine.
