Investment Analysis for Actuarial Exams
Welcome to the module on Investment Analysis, a crucial component for actuarial exams. This section will equip you with the fundamental principles and techniques used to evaluate investment strategies, understand risk, and make informed financial decisions. We'll cover key concepts like present and future values, interest rates, and the valuation of various financial instruments.
Core Concepts: Time Value of Money
The cornerstone of investment analysis is the Time Value of Money (TVM). This principle states that a sum of money is worth more now than the same sum will be in the future due to its potential earning capacity. Understanding TVM is essential for comparing cash flows that occur at different points in time.

Interest Rates and Their Impact
Interest rates are the price of borrowing money or the return on lending money. They play a pivotal role in investment analysis, influencing both the growth of investments and the cost of capital. We will explore different types of interest rates and their implications.
| Concept | Simple Interest | Compound Interest |
|---|---|---|
| Calculation Basis | Interest is calculated only on the principal amount. | |
| Growth | Linear growth over time. | |
| Formula (for FV) | FV = P * (1 + rt) | |
| Calculation Basis | Interest is calculated on the principal amount plus accumulated interest. | |
| Growth | Exponential growth over time. | |
| Formula (for FV) | FV = P * (1 + i)^n |
Understanding the difference between simple and compound interest is crucial. Compound interest, often referred to as 'interest on interest,' leads to significantly higher returns over longer periods, making it a key driver of wealth accumulation.
Valuation of Financial Instruments
Actuaries are often tasked with valuing financial instruments. This involves determining their fair market price based on expected future cash flows and the required rate of return.
The concept of discounting future cash flows to their present value is fundamental to investment analysis. Imagine a series of future payments. To find their current worth, we apply a discount rate, which reflects the risk and opportunity cost associated with receiving that money later. The further into the future a cash flow occurs, the lower its present value will be, assuming a positive discount rate. This process is visualized as a series of cash flows shrinking as they are brought back to the present.

Risk and Return
Investment analysis inherently involves managing risk. Higher potential returns are typically associated with higher levels of risk. Understanding and quantifying this relationship is key to constructing optimal investment portfolios.
The fundamental trade-off in finance: higher expected returns usually come with higher risk.
Key metrics for assessing risk include standard deviation (volatility) and beta (sensitivity to market movements). Actuaries use these measures to model potential outcomes and make recommendations that align with client risk tolerances.
Key Formulas and Applications
