What Are Stocks?
Stocks, also known as shares or equities, represent ownership in a corporation. When you purchase a stock, you're buying a small piece of that company. As a shareholder, you're entitled to a portion of the company's assets and earnings proportional to the number of shares you own.
Companies issue stocks to raise capital for various purposes such as expanding operations, funding research and development, or paying off debt. In return, investors hope to profit from the company's growth through stock price appreciation and dividends.
- Common Stock: Provides voting rights and potential dividends
- Preferred Stock: Fixed dividends, priority over common stock in bankruptcy
- Growth Stocks: Companies expected to grow faster than average
- Value Stocks: Undervalued companies trading below their intrinsic worth
- Dividend Stocks: Companies that regularly distribute profits to shareholders
How Is Stock Price Determined?
Stock prices are determined by supply and demand in the market. When more people want to buy a stock (demand) than sell it (supply), the price goes up. Conversely, when more people want to sell than buy, the price goes down.
Factors Affecting Stock Price
- Company Earnings: Strong profits typically lead to higher stock prices
- Revenue Growth: Increasing sales signal a healthy business
- Industry Trends: Sector-wide changes affect related stocks
- Economic Conditions: Interest rates, inflation, and GDP growth
- Market Sentiment: Investor confidence and speculation
- Company News: Product launches, leadership changes, acquisitions
How to Calculate Stock Profit
Calculating your stock profit involves comparing what you paid for the shares with what you receive when selling them, minus any fees or commissions.
Gross Profit = (Selling Price - Purchase Price) × Number of Shares
Net Profit = Gross Profit - Buy Commission - Sell Commission
ROI (%) = (Net Profit / Total Investment) × 100
Example Calculation
Let's calculate the profit for an investment:
- Bought 100 shares at $50 each = $5,000
- Sold 100 shares at $75 each = $7,500
- Buy commission: $10
- Sell commission: $10
- Total Investment: $5,000 + $10 = $5,010
- Total Revenue: $7,500 - $10 = $7,490
- Net Profit: $7,490 - $5,010 = $2,480
- ROI: ($2,480 / $5,010) × 100 = 49.50%
Understanding Return on Investment
Return on Investment (ROI) is a performance measure used to evaluate the efficiency of an investment. It compares the amount gained or lost relative to the initial investment.
| ROI Range | Performance | Interpretation |
|---|---|---|
| > 20% | Excellent | Outstanding returns, outperforming most benchmarks |
| 10-20% | Good | Solid returns, meeting or exceeding market average |
| 0-10% | Moderate | Positive but below average market returns |
| < 0% | Loss | Investment lost money |
Trading Fees and Commissions
When buying and selling stocks, you may incur various fees that reduce your overall profit:
- Brokerage Commission: Fee charged by your broker per trade
- SEC Fee: Small regulatory fee on sell orders
- Exchange Fees: Fees charged by stock exchanges
- Spread: Difference between bid and ask prices
- Account Maintenance: Monthly or annual account fees

Frequently Asked Questions
What is a good return on stocks?
The S&P 500 has historically returned approximately 10% per year on average. Individual stock returns can vary widely. A return that beats the market average is generally considered good, but expectations should be realistic and based on your investment timeline and risk tolerance.
What are "stonks"?
"Stonks" is internet slang for stocks, often used humorously or ironically, particularly in meme culture. It originated from a meme featuring the word "stonks" and has become popular among retail investors, especially those trading speculative or meme stocks.
How do I buy stocks?
To buy stocks, you need to:
- Open a brokerage account with a licensed broker
- Fund your account with money to invest
- Research stocks you want to buy
- Place a buy order through your broker's platform
- Monitor your investments regularly
Should I invest in individual stocks or index funds?
For most investors, index funds offer diversification and lower risk compared to individual stocks. Individual stocks can provide higher returns but also carry more risk. A balanced approach might include both: index funds for core holdings and individual stocks for additional growth potential.
How do taxes affect stock profits?
