Fundamental concepts (e.g., What is a stock broker?)

 Great — let’s start with the fundamental investing concepts 👇


🧩 1. What is a Stock Broker?

A stock broker is a company or individual that helps you buy and sell stocks (or other securities) in the stock market.

  • Think of a broker as a bridge between you (the investor) and the stock exchange (like NASDAQ or NYSE).
  • You can’t directly buy shares from the exchange yourself — you must go through a licensed broker.

Examples:

  • Online brokers: Charles Schwab, Fidelity, Interactive Brokers, Robinhood, eToro, etc.
  • Traditional brokers: Merrill Lynch, Morgan Stanley (with human advisors).

How they earn money:

  • Commissions or spreads on trades.
  • Account fees (in some cases).
  • Interest on uninvested cash.

💡 2. What is a Stock?

A stock (or share) represents ownership in a company.

  • When you buy a stock, you own a small part of that company.
  • If the company grows and earns profits, your stock value can increase and you may receive dividends.

💰 3. What is the Stock Market?

The stock market is where people buy and sell ownership shares of companies.

  • It’s like a marketplace for investors.
  • Examples: New York Stock Exchange (NYSE), NASDAQ, Tokyo Stock Exchange.

🏦 4. What is an Investment Account?

It’s the account you open with a broker to hold and manage your investments.
Common types:

  • Cash account: You buy stocks with your own money.
  • Margin account: You can borrow money from the broker to buy more (higher risk).
  • Retirement account (IRA, Roth IRA): Used for long-term investing with tax benefits.

📈 5. What is an ETF (Exchange-Traded Fund)?

An ETF is a basket of many stocks or bonds that you can buy like a single stock.

  • Example: SPY (tracks S&P 500 index).
  • It’s good for diversification and lower risk.

⚖️ 6. What is a Dividend?

A dividend is money paid by a company to its shareholders, usually from its profits.

  • Example: If a company pays $1 per share annually and you own 100 shares, you receive $100 per year.
  • Not all companies pay dividends — growth companies often reinvest profits.

📊 7. What is a Portfolio?

Your portfolio is your collection of investments, such as:

  • Stocks
  • ETFs
  • Bonds
  • Cash

Good investors diversify their portfolios to balance risk and reward.
