🔰 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.

🚩 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 RatioPrice ÷ Earnings per ShareHow many years to recover your investment. Low P/E = cheap, High P/E = expensive (but high-growth stocks can justify high P/E)
P/BVPrice ÷ Book Value per ShareP/BV < 1 = below book value (may be cheap or hiding problems)
ROENet Profit ÷ Shareholders' EquityAbility to generate profit from shareholders' capital. ROE > 15% = excellent
D/E RatioTotal Debt ÷ Shareholders' EquityDebt ratio. D/E > 2 = highly leveraged and risky, D/E < 0.5 = safe
Dividend YieldDividend per Share ÷ Stock PriceReturn from dividends. Higher is better (but beware of traps)
Net Profit MarginNet Profit ÷ RevenueNet profit margin. Higher = stronger pricing power / better cost control
Current RatioCurrent Assets ÷ Current LiabilitiesShort-term liquidity. > 1.5 = good, < 1 = risky
EV/EBITDAEnterprise Value ÷ EBITDAUsed 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.
