Stock Market Explained: Basics, Trading, Returns & Strategies
Learn how the stock market works, what moves prices, how trades happen, and how to calculate returns with simple explanations and examples.
Public Limited Company and Its Role in Markets
A public limited company is a business entity that offers its shares to the general public. Once a company decides to raise capital through an Initial Public Offering (IPO), it transitions from being privately owned to publicly traded. This transformation brings both opportunities and responsibilities.
One of the most important responsibilities of a public limited company is transparency. It must regularly disclose financial results, major decisions, risks, and operational updates. These disclosures help investors make informed decisions.
Once listed, the company’s shares are traded daily on stock exchanges. Investors and traders actively participate in buying and selling these shares based on their expectations, strategies, and interpretations of information.
What is the Stock Market?
The stock market is essentially an electronic marketplace where buyers and sellers interact. It is not a physical place where people shout bids anymore; instead, everything happens digitally through trading platforms.
At its core, the stock market performs one simple but powerful function:
It matches buyers and sellers based on their price expectations.
Imagine a situation where a company is going through uncertainty, such as leadership changes. Some people may believe the company’s future is uncertain and decide to sell. Others may see it as an opportunity and decide to buy at lower prices. This difference in opinion creates trading activity.
So, the stock market thrives on diverse opinions. Without disagreement between participants, there would be no trades.
Why Do People Trade in the Stock Market?
Market participants trade stocks for various reasons, including:
- Profit-making opportunities
- Long-term wealth creation
- Portfolio diversification
- Hedging against risks
- Speculation based on news or trends
Each participant enters the market with a different goal, and this diversity creates liquidity and efficiency.
What Moves Stock Prices?
Stock prices are constantly changing, and this movement is driven by information, expectations, and emotions.
1. Impact of News
News plays a major role in price movement:
- Positive news (e.g., strong earnings, new leadership, expansion plans) → Prices rise
- Negative news (e.g., declining profits, regulatory issues, industry slowdown) → Prices fall
When good news is announced, buyers rush to purchase shares, often willing to pay higher prices. This leads to a rapid increase in stock prices, creating a bullish trend.
2. Industry and Economic Factors
Sometimes, news does not affect just one company but an entire sector. For example:
- A drop in IT spending affects all IT companies
- Changes in government policy impact multiple industries
In such cases, the entire sector may move together.
3. Demand and Supply
Even without major news, prices can change due to demand and supply:
- More buyers than sellers → Price rises
- More sellers than buyers → Price falls
Large, well-known companies tend to see continuous trading activity, while smaller companies may experience little to no movement due to lack of interest.
4. Market Sentiment
Investor psychology also plays a key role. Optimism leads to buying, while fear leads to selling. This emotional component can sometimes drive prices beyond their fundamental value.
How Does a Stock Trade Actually Happen?
When you decide to buy shares, a structured process takes place behind the scenes:
- Order Placement
You log into your trading account and place a buy or sell order. - Validation by Broker
Your broker checks:- Account details
- Available funds or shares
- Order price and quantity
- Order Transmission
The order is sent to the stock exchange. - Order Matching
The exchange matches your order with an opposite order:- Buyer matches with seller
- Matching is based on price and quantity
- Trade Execution
Once matched, the trade is executed instantly. - Settlement
- Shares are credited to your DEMAT account
- Money is transferred to the seller
This entire process happens within seconds due to advanced technology.
What Happens After You Own a Stock?
Owning shares makes you a partial owner of the company. Even a small number of shares gives you certain rights and benefits.
Shareholder Benefits
- Dividends – A portion of company profits
- Bonus Shares – Additional shares issued for free
- Stock Splits – Division of shares to improve liquidity
- Voting Rights – Participation in key decisions
- Rights Issues – Opportunity to buy additional shares
These benefits enhance the value of your investment over time.
Understanding the Holding Period
The holding period refers to how long you keep a stock after purchasing it.
- Short-term (minutes to days) – Common among traders
- Medium-term (weeks to months) – Swing trading
- Long-term (years) – Investing
Some investors prefer holding stocks for decades, believing in long-term wealth creation. Others prefer quick trades to capture short-term price movements.
How to Calculate Returns
Returns are the ultimate measure of success in the stock market.
Absolute Return
This measures total percentage gain or loss.
Formula:
Example:
- Buy at ₹3030
- Sell at ₹3550
- Return ≈ 17.16%
This is useful for short-term evaluation.
Compounded Annual Growth Rate (CAGR)
CAGR shows the annual growth rate over a period.
Where:
- ( n ) = number of years
CAGR is more accurate for comparing long-term investments because it accounts for time.
Annualized Return
If returns are generated in less than a year, they can be annualized for comparison.
Example:
- 17% return in 6 months ≈ 34% annualized
This helps compare different investments fairly.
Traders vs Investors
Every market participant falls broadly into two categories:
Traders
Traders focus on short-term price movements and quick profits.
Types of Traders
- Day Traders – Open and close positions within the same day
- Scalpers – Make very small profits multiple times a day
- Swing Traders – Hold positions for days or weeks
Traders are highly active and constantly monitor the market.
Investors
Investors focus on long-term wealth creation and company growth.
Types of Investors
- Growth Investors – Invest in companies with high future potential
- Value Investors – Invest in undervalued stocks with strong fundamentals
Investors are patient and rely more on fundamentals than short-term fluctuations.
Where Do You Fit In?
Your role in the stock market depends on:
- Risk tolerance
- Time availability
- Financial goals
- Knowledge and experience
Some people prefer the fast-paced nature of trading, while others choose the steady approach of investing. Over time, many participants develop a hybrid strategy.
