🔰 What Are Stocks? — The Basics You Need to Know
When a company wants to raise capital to expand its business, instead of borrowing from a bank (which requires paying interest), the company can "sell shares" to investors through an IPO (Initial Public Offering) — the first time shares are offered to the public. After the IPO, shares trade on the Secondary Market or stock exchange, where investors buy and sell from each other, with prices moving based on supply and demand.
💡 Advantages of Stocks: High liquidity (easy to trade), long-term returns above inflation, dividends as Passive Income, actual ownership in the company, and you can start investing with a small amount of money.

Choosing Dividend Stocks
Dividend stocks are shares of companies that regularly distribute profits back to shareholders, typically paying 1-2 times per year. This group is suitable for investors seeking Passive Income or a steady cash flow.
Criteria for selecting quality dividend stocks:
- Dividend Yield — Dividend per share ÷ Stock price. Normally 2-6%; if above 8%, it may be a trap
- Payout Ratio — The proportion of profit paid as dividends. Should not exceed 80%; paying too much means no money left for reinvestment
- Dividend payment history — Consistent payments for ≥ 5 years with an upward trend
- Free Cash Flow — Must have sufficient cash flow to pay dividends, not borrowing to pay them
- DPS (Dividend Per Share) — Dividend per share; observe the growth trend
Examples of notable dividend stocks on SET: PTT (Yield 5-6%), SCB (4-5%), ADVANC (3-4%), AOT (1-2% but good Capital Gain), BBL (3-4%), INTUCH (3-5%), TISCO (5-7%)
📌 Tax Benefits: Dividends from Thai stocks are subject to 10% withholding tax, and you can claim a dividend tax credit, meaning low-income earners may receive a tax refund.
Financial Statement Analysis — An Investor's Foundation
Financial statements are a report on a company's financial health. There are 3 main statements investors must learn to read:
- 1. Income Statement — Shows revenue, costs, and profit over a period
→ Revenue → COGS → Gross Profit → Operating Expenses → EBIT → Interest Expense → Tax → Net Profit
- 2. Balance Sheet — A snapshot of financial position at a specific point in time
→ Accounting equation: Assets = Liabilities + Shareholders' Equity
→ Current Assets (Cash, Accounts Receivable, Inventory) vs Non-current Assets (Land, Buildings, Machinery)
- 3. Cash Flow Statement — Actual cash in and out, the most important because "Cash is King"
→ Operating CF — should be positive
→ Investing CF — negative = expanding the business
→ Financing CF — borrowing / paying dividends / raising capital
🚩 Red Flags in Financial Statements: Profit growing but cash flow negative, accounts receivable growing faster than revenue, abnormal inventory buildup, short-term debt exceeding cash, and frequent changes in accounting policies.
🔢 Financial Ratios
Financial ratios help you compare companies of different sizes:
| Ratio |
Formula |
Meaning |
| P/E Ratio | Price ÷ Earnings per Share | How many years to recover your investment. Low P/E = cheap, High P/E = expensive (but high-growth stocks can justify high P/E) |
| P/BV | Price ÷ Book Value per Share | P/BV < 1 = below book value (may be cheap or hiding problems) |
| ROE | Net Profit ÷ Shareholders' Equity | Ability to generate profit from shareholders' capital. ROE > 15% = excellent |
| D/E Ratio | Total Debt ÷ Shareholders' Equity | Debt ratio. D/E > 2 = highly leveraged and risky, D/E < 0.5 = safe |
| Dividend Yield | Dividend per Share ÷ Stock Price | Return from dividends. Higher is better (but beware of traps) |
| Net Profit Margin | Net Profit ÷ Revenue | Net profit margin. Higher = stronger pricing power / better cost control |
| Current Ratio | Current Assets ÷ Current Liabilities | Short-term liquidity. > 1.5 = good, < 1 = risky |
| EV/EBITDA | Enterprise Value ÷ EBITDA | Used for cross-industry comparisons. EV/EBITDA < 10 = cheap |
🎯 Value vs Growth Investing
Two fundamentally different investment approaches:
💎 Value Investing
- Find stocks priced below their true value (Intrinsic Value)
- Use P/E, P/BV, DCF to find "Margin of Safety"
- Hold long-term, waiting for the market to recognize value
- Masters: Benjamin Graham, Warren Buffett
- Examples: Cyclical stocks, dividend stocks, Turnaround stocks
🚀 Growth Investing
- Find stocks with faster-than-average earnings/revenue growth
- Willing to pay a premium (high P/E) if growth justifies it
- Focus on future potential, not cheap price
- Masters: Peter Lynch, Philip Fisher
- Examples: Tech Startups, SaaS, EV, AI
GARP (Growth at a Reasonable Price): A hybrid of Value and Growth — buying growth stocks but not at excessive valuations. Look at the PEG Ratio (P/E ÷ Growth Rate); if PEG < 1 = reasonable.
