Introduction

Stock exchanges are key components of the financial system, serving as organized platforms for buying and selling securities. They enable investors to trade existing securities in the secondary market, ensuring liquidity and market efficiency. The chapter explores stock exchange functions, trading mechanisms, types of securities, and settlement processes.

Trading Mechanisms on Stock Exchanges

The stock exchange facilitates trading through a well-defined mechanism, ensuring transparency, fairness, and security. Transactions occur electronically, with brokers acting as intermediaries between buyers and sellers.

Types of Securities Traded

1. Listed Cleared Securities:

   • Securities meeting all listing conditions and authorized for trading.
   • Examples: Shares, bonds, and derivatives.

2. Permitted Securities:

   • Securities listed on recognized exchanges but traded with special permission.

Types of Delivery in Trading

1. Spot Delivery:
   • Securities and payments are exchanged on the same or the next working day.
2. Hand Delivery:
   • Transactions settled by a specified delivery date set by exchange authorities.
3. Special Delivery:
   • Delivery occurs beyond the standard timeframe as per specific agreements.

Margin and Margin Trading

Margin refers to a portion of the transaction value paid upfront by the investor, enabling leveraged trading. SEBI introduced margin trading to reduce speculation and price volatility.

Key Terms:

1. Initial Margin:
   • Minimum deposit required before executing a trade, calculated as a percentage of the transaction value.
2. Maintenance Margin:
   • Minimum funds that must remain in the account to hold positions.
3. Margin Call:
   • Triggered when funds fall below the maintenance margin, requiring the investor to replenish the account.

Advantages:

• Enhances purchasing power, allowing investors to control larger positions.
• Helps curb speculative trading, promoting market stability.

Book Closure and Record Date

1. Book Closure:

   • Temporary suspension of share transfers to determine shareholders eligible for dividends, bonuses, or rights issues.
   • Companies must notify the public at least seven days prior through newspaper announcements.

2. Record Date:

   • The cutoff date for identifying shareholders entitled to benefits such as dividends or rights.

Trend Line and Trading Volume

1. Trend Line:

   • Tracks the consistent direction of share prices over time.
   • Bullish Trend: Upward movement with increasing buyer interest.
   • Bearish Trend: Downward movement dominated by sellers.

2. Trading Volume:

   • Indicates market activity and investor interest in specific securities.
   • High volumes during bullish trends signify strong market sentiment.

Clearing and Settlement Procedures

The clearing and settlement process ensures seamless execution of trades, transferring securities to buyers and funds to sellers.

Key Phases:

1. Trading:

   • Orders are placed via brokers and matched electronically.
   • Trades are executed using unique client IDs and ISIN codes for securities.

2. Clearing:

   • Identifies obligations of buyers and sellers.
   • Clearing houses, like NSCCL, oversee the process using multilateral netting.

3. Settlement:

   • Actual transfer of funds and securities between buyers and sellers.
   • Settlements follow a T+2 rolling settlement cycle, where trades are completed two working days after the transaction date.

Settlement Cycle in Rolling Settlement

Activity	Day
Trading	T
Custodial Confirmation	T+1 Working Day
Securities and Funds Pay-In/Out	T+2 Working Day
