1. **State the problem:**
An investor buys a bond with a face value of 1000, paying 5% annual interest, for 3 years. The investor sells it after 2 years for 950. We need to find the realized annual compound return.
2. **Formula used:**
The compound annual growth rate (CAGR) formula is:
$$\text{CAGR} = \left(\frac{\text{Ending Value}}{\text{Beginning Value}}\right)^{\frac{1}{n}} - 1$$
where $n$ is the number of years.
3. **Calculate Beginning Value:**
The investor receives 5% interest annually on 1000, so after 2 years, the total value before selling is:
$$1000 + 2 \times (0.05 \times 1000) = 1000 + 100 = 1100$$
4. **Calculate CAGR:**
Using the formula with Beginning Value = 1000, Ending Value = 950 + interest received, but since the investor sells at 950, the total return includes the interest payments received during the 2 years.
The investor received $50 each year for 2 years, total $100 in interest, plus $950 from selling the bond.
Total amount received after 2 years = $950 + $100 = $1050
Now calculate CAGR:
$$\text{CAGR} = \left(\frac{1050}{1000}\right)^{\frac{1}{2}} - 1 = (1.05)^{0.5} - 1$$
5. **Simplify:**
$$ (1.05)^{0.5} = \sqrt{1.05} \approx 1.0247$$
6. **Final answer:**
$$\text{CAGR} \approx 1.0247 - 1 = 0.0247 = 2.47\%$$
The investor's realized annual compound return is approximately 2.47%.
