What is the share market? What Does It Do and How Does It Work with examples

Once an investor decides to acquire shares in publicly traded companies, they enter a sophisticated ecosystem designed to facilitate reliable transaction execution and ongoing ownership management. This educational guide explores the practical mechanics of share transactions, ownership implications, and performance measurement methodologies that form the foundation of effective securities investing.

The Transaction Mechanics: From Decision to Execution

The modern share purchase process represents a marvel of technological efficiency—transforming investor intentions into completed transactions within seconds through sophisticated electronic systems. Understanding this process provides valuable context for appreciating the infrastructure supporting contemporary market participation.

The Purchase Initiation

Let us examine a practical scenario: deciding to invest in 200 shares of Tata Consultancy Services (TCS) at ₹3,030 per share with a one-year investment horizon. This straightforward investment decision activates a complex sequence of verification, matching, and settlement processes ensuring reliable transaction completion.

The process begins with accessing your authorised broker’s trading platform—typically through secure digital interfaces available across multiple devices. Once authenticated, you submit a purchase order specifying three critical parameters:

The security identifier: The specific company shares (TCS in this example)

The quantity: The number of shares sought (200 units)

The price parameters: The acceptable purchase price (₹3,030 per share)

The Verification Sequence

Before transmission to the exchange, your broker’s systems conduct comprehensive verification ensuring transaction viability:

• Account validation: Confirming proper authentication and authorisation
• Trading permissions: Verifying appropriate market access rights
• Price verification: Ensuring the specified price falls within acceptable parameters
• Quantity validation: Confirming the requested amount meets minimum and maximum limitations
• Fund sufficiency: Verifying adequate financial resources supporting the total transaction value (₹606,000 in this example)

This multidimensional verification creates essential safeguards preventing invalid or improperly funded transactions from entering market systems—protecting both individual participants and broader market integrity.

The Exchange Interaction

Upon successful verification, your order transmits to the appropriate exchange where sophisticated matching algorithms identify potential counterparties offering compatible sell intentions. These matching systems consider both price alignment and quantity availability, potentially connecting your single buy order with multiple sell orders collectively meeting your requirements.

The exchange creates no distinction regarding counterparty configuration—whether your 200 shares come from a single seller or multiple participants offering smaller quantities makes no difference from your perspective. The exchange simply ensures complete order fulfilment when sufficient compatible selling interest exists at your specified price point.

The Settlement Process

Following successful execution, complex settlement systems ensure reliable transaction completion. These mechanisms transfer both share ownership and payment between participating parties, crediting your depository (DEMAT) account with acquired shares whilst debiting the appropriate payment amount.

Simultaneously, selling participants experience the inverse process—receiving payment credit whilst transferring share ownership. This settlement occurs within established timeframes (typically T+2 days) through regulated clearing corporations ensuring transaction integrity regardless of individual participant behaviour.

Beyond Acquisition: The Ownership Experience

Share acquisition represents merely the beginning of the investment journey, initiating a potentially lengthy ownership relationship requiring ongoing attention and strategic decision-making.

Monitoring Responsibilities

Effective share ownership requires continuous evaluation across multiple dimensions including:

• Corporate performance: Following financial results, operational achievements, and leadership effectiveness
• Strategic developments: Monitoring business model evolution, expansion initiatives, and competitive positioning
• Market perception: Tracking analyst assessments, institutional positioning, and sentiment indicators
• Broader context: Evaluating industry trends, regulatory developments, and macroeconomic influences

This multidimensional monitoring creates the informational foundation supporting ongoing ownership decisions—determining appropriate holding continuation, position augmentation, or divestment timing based on evolving circumstances.

Shareholder Status

Share acquisition establishes partial company ownership proportional to your specific holdings relative to total outstanding shares. While individual retail positions typically represent modest ownership percentages—200 TCS shares constitute approximately 0.000035% of total company equity—this ownership nevertheless confers legitimate shareholder status with associated rights and privileges.

These ownership rights include:

• Dividend participation: Receiving proportional profit distributions when declared
• Corporate action eligibility: Participating in events including stock splits, bonus issues, and rights offerings
• Voting privileges: Contributing to governance decisions through shareholder voting processes
• Information access: Receiving standardised corporate communications and performance updates

These ownership privileges create significant distinctions compared to alternative investment vehicles lacking direct ownership characteristics—providing both tangible economic benefits and intangible participation value.

The Holding Period Consideration

The “holding period”—representing the duration between acquisition and eventual divestment—constitutes an essential investment parameter influencing both strategy selection and performance assessment. This timeframe varies dramatically across different investor categories, reflecting diverse objectives, methodologies, and philosophy variations.

Whilst traditional investment approaches emphasise long-term perspectives—with Warren Buffett famously suggesting his favourite holding period is “forever”—contemporary markets accommodate extraordinarily diverse time horizons. Some professional strategies involve holding periods measured in minutes or even seconds, utilising sophisticated quantitative approaches identifying momentary price inefficiencies.

The TCS example illustrates this potential time horizon diversity—with price movement from ₹3,000 to ₹3,016 within five minutes potentially satisfying short-term investment objectives despite representing modest absolute gains. Different investors would interpret this same price movement very differently based on their specific time horizons, return expectations, and strategic approaches.

Performance Measurement: Evaluating Investment Success

Investment returns represent the fundamental performance metric determining investment success—combining income components (dividends, interest) with capital appreciation to measure overall financial benefit. Understanding appropriate calculation methodologies provides essential assessment capabilities supporting informed decision-making.

The Return Calculation Fundamentals

At its core, investment return represents the financial benefit generated through capital deployment, measured as the percentage relationship between gains and initial investment value. Different calculation approaches provide varying perspectives on this fundamental relationship, with methodology selection depending on specific circumstances and analytical objectives.

Absolute Return Measurement

The simplest performance assessment method—absolute return—measures percentage change between initial investment and final value without considering time dimensions. This straightforward calculation provides direct insight regarding total value change across the entire holding period regardless of duration.

The calculation follows a straightforward formula:

[(Ending Value ÷ Starting Value) – 1] × 100

Applying this methodology to our TCS example with purchase at ₹3,030 and sale at ₹3,550:

[(3,550 ÷ 3,030) – 1] × 100 = 17.16%

This calculation demonstrates significant absolute performance—17.16% total return representing substantial value creation through this investment. However, this methodology provides limited comparative value when evaluating investments with different holding periods, as it disregards the time dimension entirely.

Time-Adjusted Performance: The CAGR Approach

To enable meaningful comparison between investments with different holding periods, sophisticated investors utilise Compound Annual Growth Rate (CAGR) methodology—incorporating time dimensions when measuring performance. This approach calculates annualised returns regardless of actual holding duration, enabling standardised comparison across different investment opportunities.

The CAGR calculation follows this formula:

[(Ending Value ÷ Starting Value)^(1÷Years) – 1] × 100

Applying this approach to our TCS example, assuming a two-year holding period:

[(3,550 ÷ 3,030)^(1÷2) – 1] × 100 = 8.2%

This time-adjusted calculation reveals 8.2% annualised performance, still representing attractive returns compared to traditional fixed income alternatives offering approximately 5.5% whilst providing principal protection. This methodology enables proper contextualisation within broader investment landscapes by standardising performance measurement regardless of specific holding durations.

Methodology Selection Guidelines

Appropriate return calculation selection depends on specific circumstances and analytical objectives:

Absolute Return: Most appropriate for holding periods under one year or when comparing investments with identical time horizons

CAGR: Essential when evaluating investments with different holding periods, enabling standardised comparison through annualised performance measurement

Understanding these methodological distinctions enables meaningful performance assessment supporting informed investment decision-making across diverse opportunity landscapes.

Annualised Performance Interpretation

For investments with non-annual holding periods, converting absolute returns to annualised equivalents provides meaningful comparative value. This approach multiplies short-term returns proportionally to create annual equivalents, enabling comparison against standardised benchmarks and alternative opportunities.

For example, the 17.16% absolute return from our TCS example over six months would translate to approximately 34.32% annualised performance, demonstrating extraordinary value creation when expressed in standardised annual terms. This conversion enables proper contextualisation within broader investment landscapes, facilitating informed resource allocation across diverse opportunity sets.

Strategic Considerations: Beyond Mechanical Elements

Beyond these technical aspects, several strategic considerations influence effective securities investing:

Time Horizon Alignment

Successful investment strategies require careful alignment between selected securities, analytical approaches, and intended holding periods. Different market segments and individual securities demonstrate varying characteristics across different timeframes, requiring appropriate methodology selection based on specific investment objectives.

Diversification Implementation

Whilst individual securities like TCS may demonstrate attractive performance characteristics, prudent investment approaches typically involve diversification across multiple holdings. This approach reduces concentration risk whilst potentially stabilising overall portfolio performance during variable market conditions.

Income versus Appreciation Balance

Different securities offer varying combinations of income (dividends) and capital appreciation potential. Strategic portfolio construction considers this balance based on investor preferences, tax considerations, and specific financial requirements.

Transaction Cost Awareness

Frequent trading involving shorter holding periods necessarily increases transaction costs through brokerage fees, securities transaction taxes, and potential market impact. These cumulative costs can significantly impact net returns, particularly for strategies employing frequent position adjustments.
