Basics of U.S. Stock Investment: A Practical Guide for Beginners

Stock Investment is a powerful means to turn the dream of financial freedom into reality, but reckless entry can lead to significant losses. Many beginners fall into the illusion of “easy money” and regret it later. However, with proper knowledge and a systematic plan, stocks can become a reliable investment tool that continuously grows your assets. This article will guide you step-by-step through Basics of U.S. Stock Investment, from choosing a securities firm to account opening, analysis methods, and risk management.

Understanding the Nature of Stocks

What are stocks? Simply put, stocks are certificates of ownership issued by a company. Buying one share means owning a small stake in that company, and you can earn dual returns through stock price appreciation and dividends as the company grows.

For example, holding one share of a large company with a current market cap of several trillion won is only about 0.000001% of the total equity. However, even this tiny stake makes you an official owner of the company and grants you the right to receive a portion of its profits.

Diagnosing Your Investment Profile

Stock investment is not suitable for everyone. Before starting, you should honestly assess your financial situation, risk tolerance, and available time.

The appeal of stocks lies in their excellent returns. Historical data shows that the U.S. S&P 500 index has averaged about 10% annual return since 1957, significantly outpacing inflation over the long term. By leveraging the power of compound interest, your initial capital can multiply several times over 20 or 30 years.

Additionally, stocks are more liquid than real estate. You can sell immediately when needed and convert to cash, which is a major advantage.

However, stock prices exhibit unpredictable volatility. During the COVID-19 pandemic in March 2020, the S&P 500 plummeted about 34% in just one month. Without psychological preparedness for such sharp fluctuations, you might panic and make poor investment decisions.

Various Ways to Invest in Stocks

Before choosing an investment method, it’s important to understand the characteristics of each.

Direct investment in individual stocks is the most basic approach, involving buying and selling specific company shares. If you conduct thorough research and find quality companies, high returns are possible, but the risk of loss due to poor performance of individual companies is also high.

ETFs(Exchange-Traded Funds) and mutual funds bundle stocks of multiple companies into a single product. They offer diversification, reducing risk, which is advantageous for beginners.

Fractional Shares( is a recently popular method allowing investment in high-priced stocks with small amounts of money.

Automatic savings investment involves regularly investing a fixed amount each month. Over time, this can lower your average purchase price and allows consistent investing without emotional interference.

Choosing a Securities Firm and Account Opening Procedures

The first step to successful investing is selecting a trustworthy securities firm.

Consider the following factors when comparing firms:

• Trading Fees: Fees vary among firms. Phone orders through staff may cost around 0.5%, which is relatively expensive, but online or mobile app trades are much cheaper. If you plan to trade frequently over the long term, prioritize low fees.

• Platform Usability: Ensure the mobile app and web interface are intuitive and easy to use. Complex platforms can cause you to miss investment opportunities.

• Customer Service: Check if support is prompt and friendly in case issues arise.

Account opening process involves:

Step 1: Decide on a securities firm
Review fees, app usability, and reputation to select the most suitable one.

Step 2: Identity verification
Download the mobile app, scan your ID)such as a resident registration card, driver’s license, or passport(, and complete phone authentication. This process is part of financial regulatory compliance.

Step 3: Enter personal information
Accurately input details such as income sources, investment experience, and investment goals.

Step 4: Agree to terms
Review and agree to online trading terms, risk disclosures, and service agreements.

Step 5: Completion
Once all steps are completed, you will receive a notification that your account is ready, and you can start trading immediately.

Choosing the account type is also important:

• General Custodial Account: Basic account for stock trading, allowing trading of domestic and international stocks.

• Tax-Advantaged Account: Government-supported accounts encouraging long-term investment, offering tax deductions up to a certain amount, providing significant tax benefits.

• Comprehensive Asset Management Account)CMA(: Flexible account where you can earn interest on deposits while investing in stocks simultaneously.

Note: If you recently opened an account with a specific financial institution, you must wait 20 business days before opening a new account with another institution. This regulation aims to prevent financial crimes.

Two Pillars of Stock Analysis

Thorough analysis of companies and markets is essential before making investment decisions. Two widely used analysis methods in stock investing are:

Technical Analysis predicts future stock prices based on past price and volume patterns. It involves reading charts and using indicators like moving averages)Moving Average( and MACD)Moving Average Convergence Divergence( to determine optimal entry and exit points. This method is mainly used by short-term traders.

Fundamental Analysis evaluates a company’s financial statements, management performance, and industry outlook comprehensively. Indicators like PER)Price-to-Earnings Ratio(, PBR)Price-to-Book Ratio(, and ROE)Return on Equity( help assess the true value of a company. It is more suitable for long-term investors.

Successful investors often combine both analyses: identifying quality companies through fundamental analysis and timing entry points with technical analysis.

Investment Strategies: Short-term vs Long-term

Your investment goals and personality should guide your strategy.

Short-term speculation involves buying and selling within days or weeks to seek quick profits. Day trading is a typical example. While offering high profit opportunities, it also carries significant risk of loss. Frequent trading can also lead to high cumulative fees.

Long-term investing involves holding stocks of quality companies for over 5 years or even decades. Warren Buffett is a prominent long-term investor. The main advantage is the power of compound interest. Over time, dividends and stock appreciation work together to exponentially increase your assets.

Long-term investing can also benefit from tax advantages. Many countries offer lower tax rates or tax-privileged accounts for holding stocks long-term.

Risk Management: Minimizing Losses

Wise investors focus equally on managing losses as on earning profits.

Diversification principle: “Don’t put all your eggs in one basket.” Investing in various companies like Samsung, Hyundai, Naver, etc., reduces the impact of poor performance in any single stock or industry on your entire portfolio.

Setting stop-loss orders: Pre-arranged sell orders trigger automatically if the stock price falls below a certain level, preventing further losses. For example, if you buy at 10,000 won, setting a stop-loss at 9,000 won will sell automatically if the price drops to that point.

Regular portfolio review: Periodically review your holdings and adjust to maintain your target allocation. This helps respond to market changes and keep your portfolio balanced.

Dollar-cost averaging: Invest gradually over multiple times instead of all at once. For example, investing 20 million won monthly over five months instead of a lump sum can lower your average purchase price and reduce market timing risk.

Long-term holding: To avoid being swayed by short-term volatility, it’s important to hold promising companies for the long haul. Reacting emotionally to short-term fluctuations can lead to selling good companies at a loss and regret.

Practical Tips for Beginners

Start with small amounts
You don’t need to invest large sums initially. Starting with 10,000 to 100,000 won helps you learn market dynamics and build confidence.

Avoid following trends blindly
Don’t get caught up in hype around “theme stocks” or “limit-up stocks.” Overheated stocks often end in losses. Investing driven by mass hysteria is risky.

Continuously learn
Spend about 30 minutes daily reading economic news, monitoring earnings reports of companies you’re interested in, and tracking macroeconomic indicators. Investing is a lifelong learning process.

Keep an investment journal
Record reasons for each trade, entry and exit prices, target prices, and outcomes. Over time, this helps analyze your patterns, identify what decisions were correct, and learn from mistakes objectively.

Manage your emotions
Don’t let emotions control you when prices rise or fall. Trust your plan and execute consistently—this is key to success.
