2025-12-24 19:08:06

Why Invest in Stocks?

Many people choose stock investing as a means to build wealth. However, successful stock investing requires more than just luck; systematic knowledge and strategies are essential. This guide is designed to help beginners start from opening an account to making investment decisions step by step.

The appeal of stock investing lies in the potential for long-term asset growth. Historical data shows that the S&P 500 index has achieved an average annual return of about 10% since 1957, consistently exceeding inflation rates. Rather than relying solely on bank deposits, participating in corporate growth can be a smarter financial decision.

Is Stock Investing Suitable for Everyone?

To answer this question, you first need to reflect on yourself. Stock investing offers high return potential, but it also involves significant volatility risk. For example, during the COVID-19 pandemic in March 2020, the S&P 500 index dropped about 34% in just one month. It is crucial to assess whether you can psychologically handle such rapid changes and whether you are willing to dedicate enough time to analyze the market.

Becoming a successful stock investor requires continuous learning. You should not simply ride the upward trend or follow popular stocks. It’s important to clearly understand your financial situation, investment preferences, and risk tolerance before proceeding.

What Are Stocks?

Let’s go back to basics. Stocks are securities that represent ownership in a company. Buying stocks means owning a part of that company.

For example, owning one share of Samsung Electronics means owning approximately 0.0000018% of the entire company(as of February 21, 2025). Although this is a tiny stake, as the company grows, your assets also increase.

The returns from holding stocks come in two forms. First is capital gains: selling at a higher price than the purchase price yields profit. Second is dividends: a portion of the company’s profits returned to shareholders. Additionally, stocks are highly liquid, allowing you to quickly convert them into cash when needed.

Opening a Stock Trading Account

Importance of Choosing a Brokerage

To start stock investing, you first need to select a brokerage firm. This choice is more important than many realize. Many investors tend to stick with the brokerage where they initially opened their account. Therefore, choosing a brokerage with low fees and a user-friendly mobile app is advantageous for long-term investing.

As online trading has become standard, trading fees have significantly decreased. Previously, orders placed through staff involved high fees of around 0.5%, but now automated orders via mobile or PC are common, making fees much more affordable.

Understanding Account Types

Various account types can be opened through brokerages:

Custodial Account: The most common trading account, allowing investment in domestic and international stocks and various financial products.
ISA( Individual Savings Account): A tax-advantaged account for medium- to long-term investments, offering income tax benefits and suitable for long-term asset management.
CMA( Cash Management Account): Pays interest on deposits and supports both stock investments and short-term fund management.

Account Opening Procedure

The process of opening an account is simpler than you might think. Most steps can be completed online via a smartphone app:

Download the brokerage’s mobile app.
Complete identity verification using ID such as resident registration card, driver’s license, or passport.
Enter required information like personal details and income sources.
Agree to the contracts and terms, and proceed with digital signing.
Once completed, you will receive a notification of account opening.

Note: If you have recently opened a deposit or withdrawal account with a financial institution, you must wait 20 business days before opening a new account with another financial company. This regulation aims to prevent financial crimes. However, this restriction does not apply to certain partner brokerages of banks like Kakao Bank, K-Bank, or Toss Bank.

Various Methods of Stock Investing

( Direct vs Indirect Investment

Stock investment methods are broadly divided into two types: direct trading of individual stocks and indirect investment through products like ETFs or funds.

Direct stock trading involves selecting and buying specific company shares, which can yield high returns but also carries significant risk of loss. Conversely, ETFs and funds are diversified products that spread investments across multiple stocks, effectively reducing risk.

) Suitable Investment Methods for Beginners

Some popular investment methods today include:

Fractional Trading: Previously, stocks could only be bought in whole units, which posed a high entry barrier for expensive stocks. Fractional trading allows purchasing in units like 0.1 or 0.01 shares, making it ideal for beginners starting with small amounts.

Dollar-Cost Averaging: Investing a fixed amount automatically every month. For example, setting up automatic investments of 2 million KRW into specific stocks each month. This approach is suitable for beginners aiming for long-term asset growth.

Analyzing Stocks

Technical Analysis

Technical analysis involves analyzing past price movements and trading volumes to predict future stock prices, using charts and various indicators.

Key tools include Moving Averages### and MACD###. These indicators help determine trading timing. For example, if the stock price is above the moving average, it indicates an upward trend; below suggests a downward trend.

( Fundamental Analysis

Fundamental analysis deeply examines a company’s financial statements, management performance, and industry trends to assess the true value of a stock.

Key indicators include:

**PER) Price-to-Earnings Ratio(: The stock price divided by net profit; lower values suggest undervaluation.
**PBR) Price-to-Book Ratio###: The stock price divided by the company’s net assets.
**ROE( Return on Equity): Shows how efficiently a company generates profit from shareholders’ equity.

Developing an Investment Strategy

( Short-term Trading vs Long-term Investment

The success of stock investing depends on choosing the right strategy.

Short-term Trading: Engaging in frequent trades over a brief period to seek quick profits. Day trading is a typical example. While it can yield high returns, losses can also occur rapidly. Frequent trading also incurs higher fees and taxes.

Long-term Investment: Holding stocks for over five years. Warren Buffett’s value investing philosophy exemplifies this approach. The main advantage of long-term investing is the power of compound interest. Over time, investment returns can grow exponentially. Many countries also offer tax benefits for long-term investments.

Risk Management and Portfolio Construction

) Principles of Diversification

A core principle of successful investing is “not putting all eggs in one basket.”

Holding a large amount of stock in a single company exposes your entire portfolio to risk if that company faces problems. Conversely, investing across multiple sectors—such as Samsung Electronics, Hyundai Motor, and Naver—minimizes the impact of a decline in any one stock on your overall assets.

( Risk Management Strategies

Specific methods to operate a stable portfolio include:

Stop-Loss Orders: Pre-setting a price point at which stocks are automatically sold to limit losses if the price falls below that level.

Periodic Rebalancing: Reviewing and adjusting your portfolio quarterly or semi-annually to maintain target allocations, responding to market changes.

Dollar-Cost Averaging: Investing a fixed amount like 2 million KRW each month over five months instead of a lump sum of 10 million KRW. This reduces the average purchase price and spreads out risk.

Long-term Holding: Avoiding being swayed by short-term volatility by holding promising stocks for the long term to maximize compound growth.

Practical Tips for Stock Investing Success

) Advice for Beginners

Start Small: Set a modest initial investment to gain experience. It’s important to have room for mistakes and learning.

Don’t Follow Trends Impulsively: Investing in theme stocks or stocks that have doubled quickly can lead to significant losses. Make decisions based on objective analysis.

Continuous Learning and Monitoring: Spend about 30 minutes daily reading economic news, and regularly review earnings reports and key economic indicators of your interest stocks on a weekly basis.

Keep an Investment Journal: Record reasons for each trade, entry points, and final outcomes. This helps objectively analyze your investment patterns and identify areas for improvement.

Conclusion

Starting stock investing is not just about moving capital; it’s about participating in corporate growth and building your assets. Success requires thorough analysis, systematic risk management, and sound investment strategies.

Even beginners can achieve long-term asset growth by calmly building a solid foundation and investing steadily like running a marathon.
