What does variance measure?
Expert Solution & Answer
Summary Introduction
To discuss: The measures of variance.
Introduction:
Variance refers to the average difference of squared deviations of the actual data from the mean or expected return.
Explanation of Solution
The variance can measure two factors. They are as follows:
- The variances can measure on the spread of investment returns.
- This helps to determine the riskiness of returns of a security.
Conclusion
Variance is the sum of the difference of squared deviations of possible returns and the expected return multiplied by their respective probabilities.

An insurance company has liabilities of £7 million due in 10 years' time and
£9 million due in 17 years' time.
The assets of the company consist of two zero-coupon bonds, one paying
£X million in 7 years' time and the other paying £Y million in 20 years' time.
The current interest rate is 6% per annum effective.
Find the nominal value of X (i.e. the amount, IN MILLIONS, that bond X pays
in 7 year's time) such that the first two conditions for Redington's theory of
immunisation are satisfied.
Express your answer to THREE DECIMAL PLACES.
An individual is investing in a market where spot rates and forward rates
apply.
In this market, if at time t=0 he agrees to invest £5.3 for two years, he will
receive £7.4 at time t=2 years. Alternatively, if at time t=0 he agrees to invest
£5.3 at time t=1 for either one year or two years, he will receive £7.5 or £7.3
at times t=2 and t=3, respectively.
Calculate the price per £5,000 nominal that the individual should pay for a
fixed-interest bond bearing annual interest of 6.6% and is redeemable after 3
years at 110%. State your answer at 2 decimal places.
The one-year forward rates of interest, f+, are given by:
.
fo
= 5.06%,
f₁ = 6.38%, and
f2
= 5.73%.
Calculate, to 4 decimal places (in percentages), the three-year par yield.
