Equity investments represent ownership in a company. When investors purchase shares of a company, they become partial owners and are entitled to a portion of the company’s profits and assets.
Equity markets allow companies to raise capital for growth and expansion while providing investors with opportunities to earn returns through capital appreciation and dividends.
Equity investments play a central role in portfolio management and long term wealth creation.
This module introduces the structure of equity markets, the concept of market efficiency, and the fundamental methods used to value stocks.
7.1 Market Structure
Equity markets are organized systems where investors buy and sell shares of publicly listed companies.
These markets facilitate the transfer of ownership between investors and allow companies to raise capital.
Equity markets operate through two main segments.
Primary Market
The primary market is where new securities are issued for the first time. In this market, companies raise capital directly from investors.
When a company wants to raise funds, it can issue shares through processes such as:
Initial Public Offering (IPO)
A private company offers shares to the public for the first time.
Follow On Public Offering (FPO)
A publicly listed company issues additional shares to raise more capital.
Rights Issue
Existing shareholders are given the right to purchase additional shares.
The funds raised in the primary market go directly to the company to support business activities such as expansion, research, or debt repayment.
Secondary Market
The secondary market is where investors trade existing shares among themselves.
Once shares are issued in the primary market, they begin trading on stock exchanges such as:
- New York Stock Exchange
- NASDAQ
- London Stock Exchange
- National Stock Exchange
In the secondary market, the company does not receive funds from share trading. Instead, investors buy and sell shares based on their expectations about future performance.
Secondary markets provide liquidity, allowing investors to easily buy or sell shares.
7.2 Market Efficiency
Market efficiency refers to how quickly and accurately financial markets incorporate information into stock prices.
The Efficient Market Hypothesis states that stock prices reflect available information, making it difficult for investors to consistently outperform the market.
There are three forms of market efficiency.
Weak Form Efficiency
In weak form efficiency, stock prices reflect all past trading information.
This includes:
- historical prices
- trading volumes
- past market trends
If markets are weak form efficient, investors cannot earn abnormal profits using technical analysis based on historical data.
Semi Strong Form Efficiency
In semi strong form efficiency, stock prices reflect all publicly available information.
This includes:
- financial statements
- company announcements
- economic news
- analyst reports
If markets are semi strong efficient, investors cannot consistently achieve superior returns using fundamental analysis because new information is quickly incorporated into prices.
Strong Form Efficiency
Strong form efficiency assumes that stock prices reflect all information, including both public and private information.
If markets were strongly efficient, even insiders with privileged information would not be able to consistently earn abnormal profits.
In reality, most financial markets are considered semi strong efficient, while strong form efficiency rarely holds true.
7.3 Equity Valuation
Equity valuation is the process of estimating the intrinsic value of a company’s stock.
Investors compare intrinsic value with the current market price to determine whether a stock is overvalued or undervalued.
If intrinsic value is greater than market price, the stock may be considered undervalued and attractive to investors.
If intrinsic value is lower than market price, the stock may be considered overvalued.
Several models are used to estimate stock value.
Dividend Discount Model
The Dividend Discount Model values a stock based on the present value of expected future dividends.
The basic idea is that the value of a stock equals the sum of all future dividend payments discounted to present value.
Dividend Discount Model formula
Stock Value = Dividend next year / (Required return − Dividend growth rate)
Where
Dividend next year = expected dividend payment
Required return = investor’s required rate of return
Growth rate = expected annual growth in dividends
Constant Growth Dividend Model
When dividends grow at a constant rate indefinitely, the Gordon Growth Model can be used.
Stock Value = D1 / (r − g)
Where
D1 = expected dividend next year
r = required rate of return
g = constant growth rate of dividends
Factors Affecting Equity Valuation
Several factors influence stock valuation.
Company earnings
Higher earnings usually increase stock value.
Growth potential
Companies with strong growth prospects often trade at higher valuations.
Risk level
Higher risk may reduce the value investors are willing to pay.
Interest rates
Rising interest rates can reduce stock valuations.
Importance of Equity Investments
Equity investments are important because they:
- provide long term capital growth
- allow investors to participate in company profits
- offer diversification opportunities
- support economic growth by providing capital to businesses
Equities are generally considered higher risk than bonds but often offer higher long term returns.
