“Don’t jump into the stock market without your own secret weapon!”
A Guide to Investing in US Stocks: Turning a novice into a master in no time

"I want to get rich by investing in stocks." "Retirement is just around the corner. What should I do next?" "I want to become a FIRE investor." Countless people are tapping into the stock market, dreaming of financial freedom.
For individual investors dreaming of wealth, stocks are the most attractive option.
But behind the sweet experience of profit, there is always anxiety and loss.
The volatile stock market is therefore both an opportunity and a source of fear.

Why does the vicious cycle of losing money by chasing buys in a rising market and then selling in a bear market driven by fear persist? It's because we lack a unique weapon, a "secret weapon."
The author, who has been investing in the domestic and international stock markets for over 20 years and has honed his own unique skills to survive, advises that one must have his own secret weapon to survive in the market for a long time.

The stock market does not discriminate between experts and non-experts.
Whether you're a large operator or an ordinary office worker, you all trade based on the same charts and news.
Despite this, some people consistently make profits, while others experience what is called a 'blank account'.
Should individual investors pass up this opportunity because it's a disadvantage? No.
Institutions that manage large funds are pressured to achieve short-term results, and thus cannot freely use the weapon called 'time'.
On the other hand, individual investors are the owners of their assets and decision makers.
If you take advantage of your strengths of sufficient time, flexible strategy, and response, it is by no means an unfavorable fight.

This book systematically presents technical analysis tools, practical trading techniques, and investment psychology management methods that can be readily applied by both beginner and intermediate investors to help them survive in the market.
To survive in the market, you shouldn't simply buy stocks that others say are good.
You need to analyze market and corporate performance data and charts, read market sentiment, and find and implement a strategy that suits you.

Investing isn't about right or wrong.
Expanding your horizons globally will reveal more opportunities.
Some people worry that investing in the United States will lead to an outflow of national wealth.
However, as of the end of May 2025, the National Pension Service's overseas stock investment ratio reached 35%.
By country, North America has the largest share at 70.5%, and by sector, IT has the highest share at 26.6%.
Looking at the stocks, familiar names such as Apple, Microsoft, Amazon, and Nvidia occupy the top spots in terms of market capitalization.

The proposition that the stock market and interest rates are inversely related is true in the long term, but it is not true at the point in time when the base interest rate has just changed and during the process.
For example, if a 100bp interest rate cut is announced to prevent the spread of the crisis, the stock market will pay more attention to the spread of the crisis and face downward pressure.
Because the impact of the economic downturn is greater than the effect of the interest rate cut.
The effects of continued interest rate cuts only begin to appear when interest rates reach a low level.

The 'W' rule is to identify the real bottom and break through the trend line.
To do this, we need to confirm the bottom not once, but twice, and break above the previous high to break the trend line.
The stock market is always sensitive to uncertainty.

The strike zone is the most advantageous area for applying signals for stock trading.
It is about finding a confidence interval with a high hit rate in a flow that cannot be predicted in any direction.
The stock market is a collection of variables.
The task is to find a point with high probability in the absence of set rules.
Because no matter how promising a company is, if you buy it at the peak of its overvalued range, you cannot avoid long-term stress.
This also destroys the virtuous cycle of long-term investment.
This is a risk that can be completely avoided if you know how to utilize trading signals in the strike zone that is advantageous for trading.

There is a proverb that says, 'Even a frog must be shaken before it can jump.'
This is a phrase that refers to preparation for a long jump, and there is a strategy in the same vein in stock patterns.
If you zoom out on the stock price graph and take a step back, you can spot a peculiarity.
There is a characteristic of moving averages converging before a significant stock price movement.
It utilizes the characteristic of moving averages that converge and then diverge, like a frog crouching.
