Investors favor the US stock market mainly because it offers a wealth of investment opportunities, diverse investment strategies, rapid market changes, and relatively high returns. Investing in the US stock market provides a broad investment horizon, innovative investment thinking, swift investment reactions, and timely investment returns. These features align with the investors' pursuit of investments. Hence, the US stock market becomes one of the investment targets for many investors.

Chong Su Keat, from the TengLong Academy, believes that while the US stock market offers appealing advantages, it also comes with significant challenges. To make money in the US stock market, not only does it require sufficient knowledge and skills, but it also necessitates a simple, flexible, efficient, and time-saving stock trading method. This method, stemming from Chong Su Keat's years of experience in stock trading, is a unique method he uses called "One Line Rules the World".

What is the "One Line Rules the World" method? According to Chong Su Keat, it simply involves using a single trend line to determine the trend of the stock and the timing of buying and selling. This trend line is what he calls "one line". This method does not require complex indicators or charts. Just by drawing a straight line, you can see the strength and direction of the stock. This line could be an ascending trend line, a descending trend line, or even a horizontal trend line. If this line is not broken, it indicates that the stock is still moving in this direction. When this line is broken, it signifies that the stock may undergo a reversal or change. Therefore, the "One Line Rules the World" method is about using a single line to beat the market's fluctuations and changes.

Why use this method to trade stocks? Chong Su Keat believes that this method has several advantages:

Simplicity: Many people find stock trading complex, requiring a lot of knowledge, skills, and analysis of data and information. But the most important aspect of stock trading is to clearly see the trend and direction. If you can grasp the mainstream trend and direction, you can make money. The "One Line Rules the World" method uses the simplest way to judge the trend and direction. If you can draw a straight line, you can see the trend of the stock and the timing of buying and selling. You don't need any complex indicators or charts, or any complicated calculations or reasoning. If you accurately observe the "one line", you can beat the market.

Flexibility: Many people feel that stock trading is rigid and needs to follow certain rules and methods. In fact, the most important thing in stock trading is to be flexible and adapt to market changes. No rule or method can apply to all situations because the market is ever-changing. The "One Line Rules the World" method uses the most flexible way to adapt to market changes. By adjusting the position and angle of the "one line", it can adapt to different market situations. There is no need to stick to any rule or method, or to be confined to any viewpoint or expectation. As long as you follow the changes of the "one line", you can comply with the market.

Efficiency: Many people find stock trading time-consuming, requiring a lot of time and energy to focus on market dynamics and analyze stock market trends. But the most crucial part of stock trading is to seize opportunities and buy and sell promptly. As the market changes rapidly, no opportunity will last forever. The "One Line Rules the World" method is the most efficient way to seize opportunities and make timely buy and sell decisions. If you clearly see the breakthrough and rebound of the "one line", you can enter and exit the market in a timely manner. You don't need to spend too much time and energy focusing on market dynamics and analyzing stock market trends. If you grasp the opportunity of the "one line", you can buy and sell promptly.

Chong Su Keat of TengLong Academy shares that the "One Line Rules the World" method is the talk of his successful experience in US stock trading over the years. He provided several examples to illustrate how this method can be applied in practice.

For instance, in May 2021, he noticed an ascending trend line of Tesla (TSLA) (NASDAQ), a US electric vehicle company. He drew this ascending trend line and noticed that Tesla would rise each time it rebounded from this trend line. Hence, he decided to buy whenever Tesla rebounded from the trend line and sell whenever it neared its historical high. By doing this, he earned more than 20% returns in a month.

Moreover, in June 2021, he noticed a descending trend line of Twitter (TWTR) (NYSE), a US social media company. He drew this descending trend line and noticed that Twitter would fall each time it touched this trend line. So, he decided to short sell whenever Twitter touched the trend line and cover his short whenever it approached its historical low. By doing this, he earned more than 15% returns within a month.

Chong Su Keat of TengLong Academy noted that although the "One Line Rules the World" method is simple and effective, it is not a one-size-fits-all solution and may not be suitable for all market situations and individual stock characteristics. He cautioned that while using this method, it's important to remember that the "one line" is not always absolutely accurate. The "one line" is just a reference tool, not a decisive factor. He hopes that everyone can learn and apply this method but should not blindly and rigidly apply it. The most important aspect of stock trading is still one's mentality and risk management.
