Understanding Securities Market Terms is essential for anyone starting their investment journey. From stocks and bonds to market indices and trading orders, knowing these terms helps you interpret market movements, follow financial news, and make smarter investment decisions. 

This article covers the most commonly used Securities Market Terms in a simple and practical way.

What Are Securities Market Terms?

Before buying your first share, you must understand the environment you are entering. The financial ecosystem relies on specific words to describe its daily operations and participants.

A securities market is a general place where financial assets like shares, bonds, and derivatives are bought and sold. It serves as a platform that connects companies looking for capital with individuals who want to grow their savings.

To help you get started, here is a list of the foundational entities you will encounter:

  • Stock Exchange: A regulated platform where buyers and sellers meet to trade existing shares. Examples include major global and national exchanges.

  • Broker: A registered middleman or firm that executes buy and sell orders on behalf of an investor.

  • Demat Account: A digital account used to hold your shares and financial securities in an electronic format, eliminating the need for physical certificates.

  • Trading Account: An account linked to your bank and Demat accounts, used specifically to place buy and sell orders in the market.

How Do Primary and Secondary Markets Work in the Securities Market?

The market is split into two distinct areas depending on how and when a financial asset is sold. Understanding this division is a core part of mastering investment basics.

The Primary Market

The primary market is where a company creates and issues new shares to the public for the very first time. This process is commonly known as an Initial Public Offering (IPO). When you buy shares in an IPO, your money goes directly to the company to help it expand its operations, launch new products, or pay off old corporate debts.

The Secondary Market

Once the IPO is complete, those shares move to the secondary market, which is what most people refer to when they talk about the stock market. In this space, investors trade existing shares among themselves. The company that issued the shares is not directly involved in these daily transactions, and the money changes hands purely between buyers and sellers.

Which Securities Market Terms Explain Price Movements?

When you watch financial news, you will constantly hear analysts use colourful financial market terminology to describe whether prices are going up or down. Learning these phrases helps you understand market sentiment quickly.

Bull and Bear Markets

A bull market refers to a financial period where share prices are rising consistently, and investor confidence is incredibly high. People are optimistic, which encourages more buying.

Conversely, a bear market is a period where share prices fall by approximately 20% or more from recent highs, driven by widespread pessimism and fear. Investors tend to sell their assets to protect their capital, which pushes prices even lower.

Volatility and Liquidity

Two other critical terms you will encounter daily are liquidity and volatility:

  • Volatility: A measurement of how quickly and drastically a share price moves up or down over a short period. High volatility means big price swings.

  • Liquidity: The ease with which an asset can be converted into cash without affecting its market price. A highly liquid share has plenty of active buyers and sellers at any given moment.

Quick Tip: For beginners, focusing on highly liquid shares with low volatility is generally safer because it allows you to enter and exit trades easily without experiencing sudden, massive price drops.

What are the Main Securities Market Terms for Order Execution?

When you open your trading platform to place your very first transaction, you will be faced with several options regarding how your order should be processed.

Types of Orders

You do not always have to buy a share at its current flashing price. Understanding order types gives you greater control over your capital:

  • Market Order: An instruction to buy or sell a share immediately at the best available current market price.

  • Limit Order: An instruction to buy or sell a share only at a specific price that you set, or better. The trade will not execute unless the market hits your target.

  • Stop-Loss Order: A safety order placed to limit an investor's potential loss. If the share price drops to a specific level, the order triggers automatically to sell the asset and stop further financial damage.

Technical Analysis Tools

Traders often use specific charts and numbers to predict future price movements. Two common terms used in this process are:

  • Support Level: A price point where a falling share price historically tends to stop dropping and bounce back up, due to a concentration of buying interest.

  • Resistance Level: A price point where a rising share price historically struggles to break through, as sellers usually enter the market to take profits.

How Do Securities Market Terms Explain Corporate Actions?

Companies frequently make structural adjustments that directly affect their shareholders. These actions can alter the number of shares you own or give you direct payouts.

Dividends and Earnings

A dividend is a portion of a company's net earnings that its board of directors decides to distribute directly to shareholders as a reward for their investment. Dividends are usually paid out in cash per share, offering a steady stream of passive income.

Share Splits and Bonus Shares

Sometimes a company wants to make its shares more affordable for retail investors, so it uses corporate actions to alter its share structure:

  • Stock Split: An action where a company divides its existing shares into multiple new shares to lower the individual share price. While the number of shares you own increases, the total value of your investment remains exactly the same.

  • Bonus Shares: Extra shares given to existing shareholders at zero additional cost, distributed based on the number of shares an investor already holds.

What are the Common Securities Market Terms Used in Company Valuation?

Before buying a piece of a company, you need to know if it is reasonably priced or far too expensive. Investors use specific ratios to evaluate a share's worth.

Market Capitalisation

Market capitalisation, or market cap, represents the total market value of a company’s outstanding shares. It is calculated by multiplying a company's total shares by the current price of a single share. This number allows investors to categorise businesses into different risk levels:

  • Large-Cap: Massive, well-established businesses that are generally stable but grow at a slower, steady pace.

  • Mid-Cap: Medium-sized companies that offer a balanced mix of growth potential and moderate risk.

  • Small-Cap: Younger, smaller companies that have high growth potential but come with a much higher risk of financial failure.

Valuation Ratios

To dive deeper into a company's financial health, you should learn these basic metrics:

  • Price-to-Earnings (P/E) Ratio: A ratio calculated by dividing the current share price by the company's earnings per share. It helps you see how much the market is willing to pay for every pound the company earns.

  • Book Value: The net asset value of a company if it were to be liquidated immediately, representing the core physical worth of the business.

Understanding these basic securities market terms changes the way you look at financial news and manage your money. By mastering this stock market glossary, you move away from guesswork and closer to making informed, data-driven financial choices.

FAQs

What is the difference between equity and bonds?

Equity represents owning a fractional piece of a company, which offers potential profits through price growth but carries higher risk. Bonds are loans you make to a government or corporation that pay you back with fixed interest over time, offering lower risk.

What does it mean when a share is shorted?

Short selling is a trading strategy where an investor borrows shares and sells them immediately, hoping the price will drop in the future. The investor aims to buy the shares back later at a lower price to return them, pocketing the difference as profit.

How does inflation affect the securities market?

High inflation typically reduces consumer spending power and raises corporate costs, which can lower company profits. Central banks often raise interest rates to combat inflation, which can cause share prices to decline as borrowing becomes more expensive.

What is a mutual fund compared to a single stock?

A single stock represents an investment in just one specific company, exposing you to concentrated risk. A mutual fund pools money from many investors to buy a diversified basket of multiple shares or bonds, managed by a professional.

What triggers a circuit breaker in trading?

A circuit breaker is an automatic regulatory mechanism that temporarily halts all trading on an exchange during severe market declines. It is triggered by sudden, massive percentage drops in major indexes to prevent panic selling and restore stability.
