“Aren’t you envious of people who claim to have made a fortune in stocks?”
Whether you’re on the subway, at a restaurant during lunch break, or catching up with an old friend over drinks, one topic never fails to come up: “The stock market.” Hearing war stories about how someone made a tidy sum with Tesla, or hit the jackpot with Nvidia, leaves you feeling left behind. You feel an urgent pressure to whip out your smartphone, open a brokerage app, and immediately buy up shares of these global giants.
Countless people around the world jump into the global stock market harboring that sweet dream of financial freedom. But the reality is cold and brutal. Statistics show that the vast majority of individual investors lose their principal, let alone make a profit, and leave the market in bitter defeat. Why is that? Is it simply bad luck? Or is the market rigged by the “powers that be”?
While external factors can’t be entirely ignored, I believe the most fundamental problem lies elsewhere. It is the utter ignorance of investors, specifically the recklessness of pouring hard-earned money into the market without even understanding the most basic terminology.
You Are Currently Walking Through a Global Minefield With Your Eyes Closed
The global stock market is a place that operates on complex and sophisticated mechanisms. Thousands of global corporations compete fiercely, and countless pieces of information from around the world are reflected in real-time, causing stock prices to dance. To survive, and eventually profit, in this massive market, you must know its language: “Stock Market Terminology.”
However, most beginner investors skip this process. They blindly follow stock picks from YouTubers or buy whatever the news claims is good. They do this without possessing the minimal tools to judge what the company actually does to make money, whether its financial health is sound, or if the current stock price is justifiable.
This is akin to traveling through the US without speaking a word of English and getting lost, or a person ignorant of medical terms attempting to perform surgery. Isn’t the outcome obvious? If you don’t know the terms, you will lose your way in this vast maze called the market, ultimately suffering irreversible losses.
If You Don’t Know These Terms, Stop Investing Immediately
Therefore, I have prepared this. The minimum basic literacy, the essential stock market terms you must possess before starting the treacherous journey of stock investing. This is not just studying; it is the minimum toolkit required for survival.
1. Basic Terms: Learning the Rules of the Global Market
- Stock: A certificate representing ownership in a company. When you buy stock, you become a shareholder of that company and gain the right to share in its profits.
- Stock Market Index: A benchmark used to measure the overall performance of a specific stock market. It acts like the market’s thermometer.
- S&P 500: An index that aggregates the stock prices of 500 large-cap companies listed on US stock exchanges. It is one of the most important indicators for grasping the trend of the global stock market.
- NASDAQ: A US stock market primarily listed with technology stocks. It is useful for tracking the trend of tech giants, including companies like Apple, Microsoft, and Google.
- Dow Jones Industrial Average: An index calculated by averaging the stock prices of 30 representative blue-chip companies in the US. Having a long history, it can be referenced to see the long-term trend of the market.
- MSCI World Index: An index that aggregates the stock prices of companies listed in developed markets worldwide. It is widely used as a benchmark for global investment portfolios.
2. Financial Statement Terms: Diagnosing the Health of Global Corporations
- Revenue/Sales: The total income a company receives from its business activities. It is the most basic indicator for judging the scale and growth potential of a company.
- Operating Income: The amount left after subtracting the cost of goods sold (COGS) and selling, general, and administrative expenses (SG&A) from revenue. It shows how much profit the company makes from its core business and is a key metric for judging a company’s actual profitability.
- Net Income: The final profit of the company after adding or subtracting non-operating income and expenses, and subtracting corporate taxes from operating income. While it represents the ultimate bottom line, it must be examined carefully as it may include one-time costs or profits.
3. Investment Ratios: A Compass for Prudent Global Investing
- EPS (Earnings Per Share): Net income divided by the total number of outstanding shares. It shows how much profit was generated per single share. Higher is generally better.
- PER or P/E Ratio (Price-to-Earnings Ratio): The current stock price divided by EPS. It indicates how expensive the stock price is relative to its earnings. Generally, a low PER implies undervalued, and a high PER implies overvalued, but because this varies by industry, comparative analysis is necessary.
- ROE (Return on Equity): Net income divided by shareholder’s equity. It shows how efficiently the company is using shareholders’ money to generate profit. It is an important indicator for judging management capability and a company’s competitiveness.
- Debt-to-Equity Ratio: Total liabilities divided by shareholder’s equity. It is an indicator for judging a company’s financial soundness; generally, below 100% is considered sound, but industry characteristics must be taken into account.
4. Expert Terms (Master These to Escape Beginner Status): For Deeper Analysis
- PBR or P/B Ratio (Price-to-Book Ratio): The stock price divided by the Book Value Per Share (BVPS). It shows how the stock price is formed relative to the company’s asset value. A PBR below 1 means the stock price is lower than its liquidation value, suggesting a high possibility of being undervalued.
- EV/EBITDA (Enterprise Value/Earnings Before Interest, Taxes, Depreciation, and Amortization): The total value of the company (EV, market cap + net debt) divided by the profit obtained through operating activities (EBITDA). It is a metric that complements PER and is useful for judging corporate value relative to cash-generating ability.
- Dividend Yield: The annual dividend per share divided by the current stock price. It shows the cash flow that can be obtained from stock investing. It is also used to judge attractiveness by comparing it with interest rates.
- Volatility: An indicator representing how severely a stock price fluctuates up and down. While high volatility means high risk, it conversely means there are many profit opportunities.
Knowing Terms Is Just the Beginning, Success Is Up to You
While countless other stock market terms exist, those compiled above are the most basic and essential. If you properly understand and utilize these terms, you will be able to grasp the flow of the global stock market, escape from reckless investing, and make more rational investment decisions.
Of course, knowing the terms does not guarantee success. It requires continuous study, market analysis, and your own investment philosophy. However, understanding the terminology is the starting point for all of that.
Are you ready to start global stock investing now? No, are you ready to fully understand these terms, analyze companies yourself, and judge the market? If not, stop investing immediately and start studying. The stock market is a land of opportunity for those who are prepared, but it is a hell for those who are not.
