Stock Market Basics: Shares, Indices, Orders and How to Start

What a share is, what an index tracks, order types and how to start investing or trading stocks carefully.

Shares and indices

A share is a small piece of ownership in a company. An index such as the S&P 500 or Nasdaq 100 tracks a basket of shares so you can see the market's overall direction. Index funds and ETFs let you buy the whole basket in one step.

Order types

A market order buys or sells at the best available price now. A limit order sets the price you will accept. A stop order triggers a market order when price reaches a level, commonly used as a stop loss. Use limit orders in thin markets to avoid bad fills.

Investing versus trading

Investors hold for years and focus on business quality and diversification. Traders hold for days or minutes and focus on price. They need different skills and different risk plans, so decide which one you are doing.

Start safely

Open an account with a regulated broker, start small, diversify and avoid borrowing to buy shares until you understand the risks. Read about taxes in your country, because rules on dividends and gains vary.

Common beginner mistakes

Buying a single stock on a tip, putting all savings into one sector, using margin before understanding it and selling in panic during a normal 10% pullback.

A diversified fund, regular contributions and a long time horizon avoid most of these, and let you learn trading with a small separate account.

Reading a stock quote

A quote shows the last price, the bid and ask, the day's range, volume, market capitalisation and the price-to-earnings ratio. Volume that is far above average means unusual interest. The bid-ask spread tells you how liquid the stock is. Check earnings dates, because prices can gap sharply on results.

Key takeaways

Shares are ownership; indices track baskets.
Limit orders control price.
Investing and trading are different.
Start small and diversify.
