What are stocks? A beginner's guide

Investing in stocks is one of the most effective ways to build wealth. To better illustrate, let's take the example of Ronald Read, a janitor and gas station attendant. When he passed away at the age of 92, he had accumulated $8 million and donated it to charity. He became the talk of the town.

You may wonder how he accumulated so much money despite his profession. He simply invested in companies he knew well. And he held onto their stocks for decades.

Most beginners get intimidated by stocks. However, with the right research and mindset, it can prove to be lucrative.

With this guide, we'll teach you the basics to help you get started.

What is a stock, and how does it work?

A stock, also referred to as a share or equity, represents a small ownership in a company. When you buy a stock, you're essentially purchasing a piece of that company, which entitles you to a share of its assets and profits. Stocks are traded on stock exchanges, making them easily accessible to investors.

Owning stock in a company means you're a partial owner, and you may benefit from the company's success through dividends (a share of the profits) and an increase in the stock's value. However, you also take on the risk if the company performs poorly.

There are two main types of companies: private and public. A private company is owned by a small group of investors and doesn't sell shares to the public. On the other hand, a public company sells shares to the general public through stock exchanges, allowing anyone to become a shareholder. Public companies are subject to more regulations and transparency requirements compared to private ones.

How are stocks bought and sold?

What is an IPO (Initial Public Offering)?

Before a company's stock becomes available to the public, it must go through an Initial Public Offering (IPO). This process allows private companies to raise funds by selling shares to investors for the first time.

Where are stocks traded?

Once listed, stocks are traded on stock exchanges such as:

• National Stock Exchange (NSE) and Bombay Stock Exchange (BSE) in India
  
• New York Stock Exchange (NYSE) and NASDAQ in the U.S.

Investors buy and sell shares on these exchanges through brokerage platforms, which act as intermediaries between the stock market and individual investors. These platforms allow investors to place orders for stocks, and once the orders are matched with those of other buyers or sellers, transactions occur.

The prices of stocks fluctuate based on supply and demand dynamics. When more people want to buy a stock (demand) than sell it (supply), the price tends to rise. Conversely, when more people want to sell than buy, the price drops. These fluctuations are a result of various factors, including company performance, market sentiment, and external events affecting the economy or industries.

Thus, stock prices are constantly changing throughout the trading day, and investors aim to make a profit by buying at lower prices and selling at a higher price to make a profit.

What are the different types of stocks?

1. Common vs Preferred Stocks

Common stocks offer voting rights and dividends. And preferred stocks do not offer any voting rights. However, shareholders with preferred stocks get priority in terms of dividend payments. Also, when the company is liquidated, they receive their money earlier as compared to common shareholders. Even in preferred stocks there are several types with the two most popular being cumulative and non-cumulative with the former indicating that dividends that are not paid earlier due to some reason will be paid to the shareholder.

2. Market Capitalisation Categories

Companies are categorised based on their market capitalisation (total value of shares outstanding).

• Large-cap stocks- They are generally established, financially stable businesses that tend to be industry leaders. They are often considered less risky and are popular among conservative investors seeking steady, long-term growth. At Value Research, large-cap stocks comprise the top 70 per cent of the total market capitalisation.
  
• Mid-cap stocks - Falling in the next 20 per cent of total market capitalisation, mid-cap companies are typically in a growth phase. They may offer substantial upside potential but can be more volatile than large-cap stocks.
  
• Small-cap stocks - These make up the next 9 per cent. Often operating in niche markets, small-cap firms can be highly volatile. While they might struggle during economic downturns, they can also deliver significant returns for investors who are comfortable with greater risk.
  
• Micro-cap stocks - These companies represent the final 1 per cent and are the smallest listed businesses. They are speculative and risky but can sometimes provide remarkable growth opportunities - albeit with a higher probability of failure.

3. Dividend Stocks vs Growth Stocks

Dividend stocks, such as Coal India or Vedanta, are characterised by high dividend yields. As a result, they pay hefty dividends during profitable periods.

On the other hand, growth stocks reinvest their earnings, looking to boost future returns. In fact, Terry Smithargues that investing in growth stocks is more advantageous as they focus on reinvesting their profits to drive future growth.

By doing so, they aim to achieve higher long-term returns through the efficient use of earnings rather than distributing them as dividends.

4. Cyclical vs Defensive Stocks

Every economy experiences cycles of expansion and contraction. Cyclical stocks belong to industries that are sensitive to these economic fluctuations. Sectors such as paper, mining, and automobiles are prime examples, as their performance tends to mirror the overall demand in the economy.

In contrast, defensive stocks remain relatively unaffected by economic cycles because they belong to sectors that provide essential goods. For instance, the FMCG sector is considered defensive, as demand for products like biscuits, detergent, and soap remains steady regardless of economic conditions. These everyday essentials are always in demand, making defensive stocks more stable during economic downturns.

To buy stocks, you need a Demat account (to store shares digitally) and a trading account (to execute transactions). You can open these accounts with banks or brokerage firms.

Step 2: Choose a Brokerage Platform

Decide between:

• Discount brokers - Lower fees, ideal for self-directed investors.
  
• Full-service brokers - Provide research and advisory services but charge higher fees.

Step 3: Learn How to Place Orders

• Market Order - Buy/sell at the current market price.
  
• Limit Order - Set a specific price to buy/sell.
  
• Stop-Loss Order - Automatically sell a stock when it drops to a certain price.

Step 4: Decide Between Short-Term Trading vs Long-Term Investing

• Short-term trading (day trading, swing trading) aims for quick profits but involves higher risk.
  
• Long-term investing focuses on gradual wealth accumulation through compound growth.

What Are the Best Stock Investing Strategies?

1. Fundamental Analysis

Uses a combination of valuation metrics and a careful study of financial statements to come up with an investment thesis. The aim is to identify potential mispricings in a stock and leverage those opportunities. This is done by identifying the intrinsic value of the company, which goes beyond book value or market value.

2. Technical Analysis

Requires the reading of stock charts and focuses on technical indicators such as the following:

• RSI (Relative Strength Index): The RSI helps identify whether a stock is overbought or oversold, giving investors a sense of when the stock might be due for a price correction. It's used to spot potential turning points in the market.
  
• Moving Averages: Moving averages show the overall trend of a stock's price by smoothing out short-term fluctuations. They help investors understand whether a stock is generally moving up or down, making it easier to identify long-term trends.

3. Value Investing vs Growth Investing

• Value Investing
  This style is popularised by Benjamin Graham, author of the book The Intelligent Investor. It involves identifying stocks that are undervalued in relation to its price based on its fundamentals. By finding such opportunities, you could discover hidden gems that are available at an attractive valuation with the potential for long-term growth.

• Growth Investing
  It is an investment style where you invest in companies that are growing aggressively and reinvesting almost all of their profits paying out little to no dividends. These are called growth or hot stocks and as a result of it investors are willing to pay a premium.

4. Passive Investing Through Index Funds and ETFs

Passive investing is a strategy that involves investing in index funds or exchange-traded funds (ETFs) to match the overall performance of a market index, like the Nifty 50 or Sensex. Unlike active investing, where you pick individual stocks, passive investing takes a hands-off approach by buying into a broad market index or sector. The goal is not to beat the market but to mirror its performance over time.

This strategy requires minimal management since the fund automatically tracks the performance of the index it's designed to follow. Investors don't need to constantly monitor or make frequent adjustments, making it a simple, low-cost way to invest. It's ideal for those who prefer long-term growth with minimal effort and believe that the market, over time, tends to rise rather than trying to predict short-term price movements.
