Introduction
No perfect security exists that meets all the needs of every investor. If it did exist, there would be no need for investment and portfolio management, and no need to measure the return and risk of investments.
t might signal a poor investment choice.
The more common practice is to express returns as a percentage, called the rate of return or yield. To convert a dollar amount to a percentage, divide the total dollar returns by the amount invested.
$$
\text{Return %} = \frac{\text{Cash Flow} + (\text{Ending Value}  \text{Beginning Value})}{\text{Beginning Value}} \times 100
$$
Rate of Return Calculation
Consider the following three scenarios to calculate rate of return:
 Scenario 1: You purchase a stock for $10 and sell it one year later for $12.
$$
Rate of Return = \frac{0 + (12  10)}{10} \times 100 = 20%
$$
 Scenario 2: You purchase a stock for $20 and sell it one year later for $22, and during this period, you receive $1 in dividends.
$$
Rate of Return = \frac{1 + (22  20)}{20} \times 100 = 15%
$$
 Scenario 3: You purchase a stock for $10 and receive $2 in dividends, but one year later you sell it for only $9.
$$
Rate of Return = \frac{2 + (9  10)}{10} \times 100 = 10%
$$
These examples show how cash flow and capital gains or losses are used in calculating a rate of return. All trading periods in the examples are set for one year, hence the percentage of return is also called the annual rate of return. If the transaction period were longer or shorter than a year, the return would be called the holding period return.
Nominal and Real Rates of Return
So far, we have looked only at a simple rate of return, otherwise known as the nominal rate of return. Besides that, the real rate of return takes into consideration the effects of inflation.
$$
Real Return = Nominal Rate  Annual Inflation Rate
$$
Example:
If a client earns a 10% nominal return on an investment with a 2% inflation rate over the same period:
$$
Real Return = 10%  2% = 8%
$$
The RiskFree Rate of Return
Tbills often represent the riskfree rate of return, given that there is essentially zero risk with this type of investment. Other securities must pay at least the Tbill rate plus a risk premium to compensate investors for the added risk.
Historical Returns
You can gain important insights into the market and determine appropriate investments and investment strategies by studying historical data.
The more common practice is to express returns as a percentage, called the rate of return or yield. To convert a dollar amount to a percentage, divide the total dollar returns by the amount invested.
$$
\text{Rate of Return} = \frac{\text{Ending Value}  \text{Beginning Value} + \text{Income}}{\text{Beginning Value}}\times 100
$$

Key Takeaways

Rate of Return: Always express investment returns as a percentage to better grasp the significance of the return relative to the amount invested.

Real Rate of Return: Adjust nominal returns for inflation to understand the true earning power of an investment.

RiskFree Rate of Return: Represents the base return with zero risk upon which other investments with higher risks are compared.

Historical Returns: While useful for insights, always remember that historical returns do not guarantee future performance.

Diversification: Essential to risk reduction by spreading investments across various securities or sectors.
Did You Know?

The return on an investment is often referred to as the expected return to emphasize the nonguarantee of returns.

Capital gains and losses contribute significantly to the overall return on an investment.
Rates of return can be defined as ExAnte or ExPost:
 ExAnte: These are expected returns based on forecasts.
 ExPost: These are returns evaluated after the investment has matured, showing historical performance.
Understanding the intricate relationship between risk and return is crucial for anyone involved in the Canadian Securities Course. This knowledge allows for better portfolio diversification and, ultimately, better client outcomes.

## What is the formula to calculate the expected return of a single security?
 [ ] (Expected Cash Flow  Expected Capital Gain) / Beginning Value
 [x] (Expected Cash Flow + Expected Capital Gain) / Beginning Value
 [ ] (Expected Cash Flow  Expected Capital Gain + Expected Ending Value) / Beginning Value
 [ ] (Expected Cash Flow + Expected Ending Value) / Beginning Value
> **Explanation:** The expected return of a single security is calculated using the sum of the expected cash flow and expected capital gain or loss divided by the beginning value of the investment.
## What is the nominal rate of return?
 [ ] Return on investment adjusted for inflation
 [x] Return on investment without adjustment for inflation
 [ ] Return after adjusting for taxes
 [ ] Return after adjusting for fees
> **Explanation:** The nominal rate of return is the return on investment without adjusting for inflation. It is the simple percentage gain calculated from the initial investment.
## How does one calculate the real rate of return?
 [x] Nominal Rate  Annual Inflation Rate
 [ ] Nominal Rate  Taxes and Fees
 [ ] Nominal Rate + Annual Inflation Rate
 [ ] Nominal Rate + Expected Return Rate
> **Explanation:** The real rate of return is calculated by subtracting the annual inflation rate from the nominal rate of return, indicating the purchasing power gain.
## What does the riskfree rate of return typically represent?
 [x] The yield on Treasury bills (Tbills)
 [ ] The return on corporate bonds
 [ ] The return on equities
 [ ] The return on government bonds
> **Explanation:** The riskfree rate of return usually represents the yield on Treasury bills (Tbills) because they are considered to have negligible risk.
## Which type of risk can be reduced through diversification?
 [ ] Systematic risk
 [x] Specific risk
 [ ] Market risk
 [ ] Inflation risk
> **Explanation:** Specific risk, or unsystematic risk, can be reduced through diversification by investing in a variety of securities, unlike systematic risk which affects the entire market.
## What is capital gain?
 [ ] The return received in the form of dividends or interest
 [x] Selling a security for more than its purchase price
 [ ] Selling a security for less than its purchase price
 [ ] The regular payment received from fixedincome securities
> **Explanation:** Capital gain is the profit earned by selling a security for more than its purchase price.
## What does "standard deviation" measure in portfolio management?
 [ ] Expected return
 [ ] Inflation rate
 [ ] Nominal rate of return
 [x] The volatility or risk of the investment’s return
> **Explanation:** Standard deviation measures the volatility or risk of an investment’s return. It indicates how much the return can deviate from the expected return.
## What is the significance of the holding period return?
 [x] It represents the return over the entire holding period, regardless of the length.
 [ ] It represents the annualized return of the investment.
 [ ] It represents the minimum return obtained on investment.
 [ ] It represents the difference between the nominal and real rate of return.
> **Explanation:** Holding period return represents the total return earned over the entire period an investment is held, irrespective of the length of the holding period.
## What does a higher standard deviation indicate about an investment?
 [ ] Lower risk and lower expected return
 [ ] Lower risk and higher expected return
 [x] Higher risk and higher expected return
 [ ] Higher risk and lower expected return
> **Explanation:** A higher standard deviation indicates higher risk, which can potentially lead to higher returns, reflecting more uncertainty and greater fluctuations in the investment’s returns.
## Why might an investor consider the Treasury bill rate while choosing an expected rate of return?
 [x] As a benchmark for the riskfree rate
 [ ] To compare with inflation rates
 [ ] To calculate capital gain
 [ ] To determine standard deviation
> **Explanation:** Investors use the Treasury bill rate as a benchmark for the riskfree rate while choosing an expected rate of return because Tbills are considered to carry negligible risk.
