Stock

Quick summary

A stock is a share of ownership in a company. When you buy a stock you own part of that company. Stocks let companies raise money and let investors try to grow their savings. Stocks can earn money in two ways. They can pay dividends. Or their price can rise so you sell for a profit. Stocks also can fall in value. That is the main risk.

What is a stock

• A stock, also called a share, represents ownership in a company.
• Owning one share gives you a small claim on the companys assets and profits.
• Stocks trade on markets called exchanges. Buyers and sellers meet there to trade shares.

Think of a company as a pie. Stocks are slices of that pie. The more shares you own the larger your slice.

Types of stocks

• Common stock: Most regular stocks are common. Common shareholders can vote on key company issues. They may get dividends if the company pays them.
• Preferred stock: Preferred shareholders usually get fixed dividends before common shareholders. They have less voting power. Preferred stock sits between common stock and bonds.

How stocks work

• A company issues stock to raise money. This happens at an initial public offering or IPO.
• After the IPO shares trade on an exchange. Prices change based on supply and demand.
• Investors buy shares hoping the company will grow. Growth can raise the companys profits and the stock price.
• If a company makes money it can pay dividends. Or it may reinvest profits to grow faster.

Why companies issue stock

• To fund growth, buy equipment, hire staff, or pay debt.
• To let early owners and employees sell some of their stake.
• Selling stock spreads ownership and risk among many people.

Why people buy stocks

• Potential for higher long term returns than savings accounts or many bonds.
• To earn dividends as income.
• To own part of a business they believe in.
• To diversify a portfolio so risk is spread across assets.

Risks and rewards

Rewards

• Capital gains: sell later for more than you paid.
• Dividends: regular cash payments from profits.
• Ownership benefits: voting rights and insider understanding.

Risks

• Price volatility: stocks can fall sharply.
• Company failure: you can lose most or all of your investment.
• Market risk: the whole market can drop due to economic events.

A simple rule: higher potential return usually means higher risk.

How to buy stocks

1. Pick a broker. This can be an online broker or an app. Compare fees, research tools, and ease of use.
2. Open and fund an account. You may need ID and a bank transfer.
3. Research the stock. Read financial reports, check news, and look at valuation metrics.
4. Decide how many shares to buy. You can buy fractional shares if available.
5. Place an order. Common order types are market orders and limit orders.
6. Monitor your investment. Revisit your reasons for buying and adjust if circumstances change.

Simple example

You buy 10 shares of Company X at $20 per share. Your cost is $200. If the price rises to $30 and you sell, you get $300. Your profit is $100 before fees and taxes. If the price falls to $10 you lose $100.

Practical tips

• Start small. Use money you can afford to leave invested for years.
• Diversify. Own different companies and industries to reduce risk.
