Topic 7 Flashcards
Average returns were used to analyse _______ returns in financial markets based on actual events.
historical
__________ of returns of an investment represents its risk and is measured by variance and standard deviation.
Variability
In Part 2, we calculate projected future returns based on probabilities of economic state in future. We call these ___________.
expected returns
________ is a group of assets held by an investor.
Portfolio
___________ is how many percents a particular asset contributes to the total value of the portfolio.
Portfolio weight
_________ on a portfolio is calculated based on portfolio weight.
Expected return
What will determine the value of a share’s return next year?
There are two components: expected and unexpected returns.
Expected return is part of the return that investors already predict, based on the information the shareholders have _______ that will influence the return in upcoming year
today
Unexpected return is the ________ part; the portion that comes from unexpected information revealed within the year, for example:
+ unexpected change in commodity prices (imagine if iron ore prices suddenly fall sharply!)
+ News that company’s sales figures are better than expected
+ News about the CEO’s sudden resignation.
risky
Total return = Expected return + _________ return
R = E(R) + U
Unexpected
So, what is risk?
Risk is the unexpected part of the total return!
Unexpected events comprising the unexpected part of total return can be divided into:
– Systematic risk: Risk affecting a large group of investments; also called _______
– Non-systematic risk: Risk affecting only a single or a small group of investments; also called _______
market risk.
unique risk.
Total return = __________ + Systematic portion + Non-systematic portion
Expected return
THE EFFECT of DIVERSIFICATION:
- If a portfolio contains a number of diversified shares, its standard deviation would be _______ than the average standard deviation of individual share.
- The more the number of shares in the portfolio, the _______ the portfolio’s standard deviation.
lower
lower
A relatively large and diversified portfolio has almost no _________ risk.
non-systematic
Systematic risk principle states that, because non-systematic risk can be eliminated by diversification, expected return on a risky asset depends only on the asset’s ________
systematic risk.
So, how do we measure systematic risk?
Beta coefficient (β) measures the amount of systematic risk in a particular investment relative to an average risky investment in the market.
+ An investment with a beta of 0.50 has half the systematic risk that an average risky investment has.
+ A beta of 2.00 means the investment has twice the systematic risk an average risky investment has.
