“The KOSPI is skyrocketing, but why aren’t my stocks rising?”
Hyoracle, a practical investor who sees through the illusion of a bull market, offers a method for selecting stocks that maximize returns.

The KOSPI index reached an all-time high in 2025.
The market is in a festive mood, with articles like "KOSPI breaks 3,800 for the first time ever" and "Is the KOSPI 4,000 era dawning?" pouring out every day.
The media makes it sound like all stocks are rising, but in reality, only a few large-cap stocks are driving the KOSPI upward.
If you don't own the rising stocks, your returns will remain stagnant or even negative, no matter how much the KOSPI rises.


Although the Korean stock market may appear no different from other countries on the surface, the structure of stock price movements is completely different.
'Stories' and 'issues' move stock prices more than a company's performance or financial statements.
A market where stock prices fluctuate based on new business announcements, political themes, or even a single comment from a celebrity—this is the reality of the Korean stock market.
But this market is actually an opportunity.
Even if you filter out only risky stocks, your returns will increase.
It is much simpler and more certain to filter out stocks that will fall than to predict which stocks will rise.
In other words, knowing 'what not to buy' rather than 'what to buy' is the most realistic way to increase your returns.

《How to Select Stocks with High Profitability》 is a book that establishes criteria for stock selection.
Author Hyoracle is a real investor with 25 million cumulative YouTube views and 229 of the 239 stocks he recommended over the past year have seen gains.
He is a data-proven investor, recording a 255% return even during the COVID-19 bear market.
He reads the market with data, not intuition.
Analyze the events and structures that drive stock prices, and find common signals among plummeting stocks.
It provides concrete examples of market structural pitfalls, such as total risk, political themes, and labor union issues, and provides precise methods for identifying stocks to buy and those to avoid.

In the past, it was said that 'cheap things are expensive', but now 'cheap things are expensive' has become a powerful means to destroy competitors.
Being cheap is never a weakness.
It's a strategy, a structure, and a weapon.
China is killing its competitors with its low prices.
Even if the quality is a little poor, it cannot withstand the onslaught of quantity.
No matter how good your technology is, you cannot survive in a battlefield where there is no profit.
Is the stock you're currently holding competing in the same industry as China? If so, it's like riding a bicycle against a truck speeding at 300 km/h.

The KOSDAQ market survives on ‘optical illusions.’
How are illusions created? First, it's about theme, not performance.
If your name appears in the news, it will definitely rise.
For example, if the government announces a policy related to artificial intelligence, even AI-related stocks with no track record will rise by tens of percent.
Even if the name contains only 'AI', it will rise.
And after a while it falls out again.
This pattern repeats itself in bio.
The stock price hits the upper limit on the news of 'success in phase 1 clinical trial'.
However, the success may be at a meaningless preclinical level, and in many cases, it ends up being meaningless as it fails to pass phase 2 or 3 trials or fails to obtain approval.
Nevertheless, investors are seduced by a single line of hopeful news, and that anticipation creates another illusion.
--- “The Third Commandment.
If you are a long-term investor, don't even look at KOSDAQ.'

Many people firmly believed that Celltrion's true value would be revealed if it went to KOSPI, where there were more excellent companies than KOSDAQ.
The market was dominated by the logic that Celltrion's stock price would naturally rise because numerous ETFs tracking the KOSPI would buy it.
But the stock price had already reflected such things long ago.
The material regarding the brisk sales of Ramsima in Europe, the expanded approval of Trusima, and the listing before KOSPI were already sufficiently spread in the market, and the stock price broke through 300,000 won on the back of these expectations.
No matter how good the material is, if there is no more news to come, expectations are bound to fade.

New keywords such as artificial intelligence and robots are born every day.
Beneficiaries of Nvidia, ChatGPT-related stocks, beneficiaries of the Ukraine War, beneficiaries of the Yellow Envelope Act, and beneficiaries of Korea-US cooperation, etc.
In the endless stream of trends, yesterday's ace becomes tomorrow's overvalued stock.
A stock that looked so good yesterday is not doing so well today.
This is the Korean stock market.
A country where people change trends too quickly, always wanting new things and buying what's changed first.
So, it is a country that global companies use as a test bed to identify trends.
Just as the fashion industry produces new products every season, the stock market also creates new keywords every year.
Stocks often rise not because they are ‘good’ but because they are ‘new’.
And no matter how good a company is, if there is nothing new to offer, its stock price will be ignored.
So remember.
'What was good last year was last year's story.
