Evaluating Fund Performance and Selection: Comprehensive Guide (Part 1)
This guide provides high-quality technical notes on evaluating fund performance and selecting appropriate retirement products, based on the NISM Series-XVII: Retirement Adviser Certification Workbook.
1. Understanding Return on Investment (RoI)
Return on Investment (RoI) is a fundamental metric used to evaluate the performance of an investment product by relating its total earnings to the initial cost of acquisition. Before selecting a fund, an investor must evaluate the type, certainty, and risks associated with these returns to ensure they align with retirement goals.
Core Components of Investment Returns
Investment returns generally manifest in two distinct forms:
- Periodic Income: This includes recurring payments such as interest from debt securities or dividends from equity holdings.
- Value Fluctuation: This refers to the capital gains or losses resulting from an increase or decrease in the market value of the investment.
Key Characteristics of Returns
- Predictability: Periodic income may be fixed and known in advance (e.g., debt interest) or variable and unknown at the time of investment (e.g., dividends).
- Realisation: Capital gains or losses may be realised through the actual sale of the asset, or they may be unrealised (notional), representing paper changes in value that still impact return calculations.
- Net Totals: Total return is the sum of periodic income and value changes; this figure can be positive or negative.
- Guarantees vs. Variables: Some products, like bank fixed deposits, offer fixed interest, while others, like the Public Provident Fund (PPF), offer guaranteed but variable interest that is reset quarterly.
2. Primary Methods of Return Calculation
To effectively compare different investment opportunities, advisers use several mathematical approaches to calculate performance.
2.1 Absolute and Percentage Returns
Absolute return is a simple comparison of the total rupees earned (income plus capital gains) against the original amount invested. While absolute figures show the total wealth gain, they fail to account for the size of the principal.
To resolve this, the percentage rate of return is used to create a common base of Rs. 100 for comparison.
- Formula: Percentage Return = (Return on Investment / Original Investment) * 100.
2.2 Annualized Returns
When investments have different holding periods, their returns cannot be compared directly. Annualization converts an absolute rate of return into a standard one-year holding period.
Standard Annualization Formulas:
- By Days: Absolute Rate of Return * (365 / Number of days held).
- By Months: Absolute Rate of Return * (12 / Number of months held).
- By Years: Absolute Rate of Return * (1 / Number of years held).
2.3 Compounded Annual Growth Rate (CAGR)
For investments held longer than one year, CAGR is the standard measure. It calculates the average annual rate at which an investment grows from start to finish, accounting for the time value of money and the compounding of returns.
- Formula: CAGR = ((End Value of Investment / Beginning Value of Investment)^(1 / n)) - 1. (Note: 'n' represents the holding period in years).
2.4 Internal Rate of Return (XIRR)
The XIRR function (Extended Internal Rate of Return) is utilised in MS Excel to calculate returns for investments characterized by volatile returns and multiple cash flows occurring at different times.
Required Data for XIRR Calculation:
- Cash Outflows: The value of each investment made (represented as a negative number).
- Cash Inflows: Dividends, interest received, and the final sale value.
- Specific Dates: The corresponding calendar dates for every inflow and outflow.
Key Terms for Exam Preparation
| Term | Definition |
|---|---|
| Periodic Income | Regular payments such as interest or dividends received from an investment. |
| Capital Gains/Losses | The change in the market value of an asset over its holding period. |
| Notional Returns | Unrealised gains or losses based on current market valuation rather than an actual sale. |
| Compounding | The process where an investment's earnings, from both previous principal and accumulated interest, are reinvested to generate additional earnings. |
Key Takeaways
- RoI is the primary metric for evaluating investment performance relative to cost.
- Absolute returns are insufficient for comparison; percentage returns and annualization are required to normalize data across different principal amounts and timeframes.
- CAGR is essential for long-term retirement planning as it reflects the true geometric growth of a corpus over years.
- XIRR is the most accurate tool for calculating returns on periodic investments like Systematic Investment Plans (SIPs).
