Risk and Return Notes
1. Key Concepts
• Risk = the chance of losing money or earning less than expected.
• Return = the profit or gain from an investment, usually expressed as a percentage.
• General principle: Higher potential return = Higher risk.
2. Types of Risk
• Market Risk – prices go up and down due to economic or political events.
• Business Risk – company profits may fall (poor management, competition).
• Liquidity Risk – difficulty selling the investment quickly without loss.
• Interest Rate Risk – changes in interest rates affect returns (esp. bonds).
• Inflation Risk – rising prices reduce the real value of returns.
• Credit Risk – risk that a borrower/company cannot pay back money owed.
3. Types of Return
capital gains - profits from selling an asset at a higher price (Buying shares that go up in value provide a capital gain. Selling shares before they go down in value can also deliver income if an investor then buys them back at a lower price. You can make a capital gain whether you're buying or selling shares.)
Dividends – the company pays part of its profit to shareholders. (Owning shares allows you to benefit from the company's profits, which can be given to you as dividends (your share of the profit based on how many shares you own) or as extra shares.)
• Interest Income – earned from lending money (e.g., bonds, savings).
• Total Return = Capital Gains + Income (dividends/interest).
4. Risk–Return Relationship
No matter what investment a person may choose, there will be risks to consider, but not all risks are created equal. Understanding the risk levels that come with different asset classes is key to helping a person decide what products are best suited for your current risk appetite and aspirations.
Low risk = low return (e.g., bank savings account, government bonds).
Medium risk = medium return (e.g., managed funds - (A managed fund is made up of a pool of money that comes from many people who have similar investment goals. A professional fund manager invests this money in assets such as shares or property. A managed fund allows a small investor to be involved in the share market and real estate), corporate bonds).
• High risk = high return (e.g., shares, property, cryptocurrency).
• Speculative/high-risk investments can produce very high gains but also large losses.
5. Diversification
• Strategy of spreading money across different investments (shares, bonds, property, cash).
• Reduces risk because poor performance in one area may be balanced by gains in another.
• "Don’t put all your eggs in one basket."
6. Risk Profiles (Investor Types)
• Conservative Investor – prefers safety and steady returns.
• Balanced Investor – mixes safe and growth investments.
• Aggressive Investor – willing to accept high risk for high potential rewards.
Task 3 Preparation
Investment: Using money to generate profit (e.g., shares, property, bonds).
Risk: Chance of financial loss.
Return: Profit or gain expressed as a percentage.
Risk–Return Principle: Higher potential return = Higher risk.
Diversification: Spreading money across different asset types to reduce risk.
Growth Assets: High risk, high return (shares, property).
Defensive Assets: Low risk, low return (bonds, term deposits).
Dividend: Company profit shared with shareholders.
Superannuation: Long-term investment for retirement, tax-advantaged.
Managed Fund: Pool of money invested across multiple assets.
Rate of Return Formula:

Then divide by the number of years
Source A – Investment Returns Table
Property: High fluctuations (e.g., +13% in Year 2, –10% in Year 3). → High risk.
Overseas Shares: Very volatile (e.g., +12% then –18%). → Very high risk.
Australian Shares: Medium volatility (+11%, –8%). → Moderate–high risk.
Government Bonds: Stable (2–3%). → Low risk, low return.
Bank Term Deposits: Safe, small return (3–5%). → Low risk.
Key idea: Growth assets (shares, property) can produce both large gains and losses, while defensive assets (bonds, deposits) are steady but with lower returns.
Source B – Five Portfolios
Albert → Mostly Bank Deposits. Low risk, low return. Conservative investor.
Manuel → Heavy in Australian Shares, some Bank Deposits. Medium-high risk. Balanced but growth-focused.
Sally → Large portion Overseas Shares + mix of others. High risk. Aggressive investor.
Rosa → Heavy Property, with small spread across others. Medium risk but less diversified.
Minh → Mix of Property, Overseas Shares, Australian Shares, Bonds, Deposits. Diversified. Medium risk.
Compare and contrast risk levels by checking balance between growth vs defensive assets.
Extended Response Focus
You will need to:
Refer directly to Source A (investment returns) and Source B (portfolios).
Show understanding of risk and return for each type of investment.
Discuss diversification and why it matters.
Justify which portfolio is most suitable for different investor profiles (e.g., young person, pre-retiree).
Use terminology (risk, return, diversification, defensive/growth assets).
Sample points to include in an extended response:
“As shown in Source A, overseas shares had a return of +12% in Year 1 but –18% in Year 2, showing they are high risk, high return investments.”
“Albert’s portfolio is dominated by bank term deposits, meaning he has a low-risk strategy suited to someone close to retirement.”
“Sally’s portfolio contains a high percentage of overseas shares, making her portfolio high risk but potentially high return, suitable for a younger investor with a long time horizon.”
“Minh’s portfolio is diversified across property, shares, bonds, and deposits, reducing risk by balancing volatile and stable investments.”
Investment Portfolio/Asset Portfolios (Growth vs Defensive)
Investment Portfolios
An investment portfolio is a collection of assets, such as shares and bonds, cash, real estate, or even cryptocurrency, owned by one person or entity. Diversifying a portfolio aims to balance any losses in one investment against gains in others. It can also be known as a collection of financial investments. There are many different financial products available to investors, and they may choose to invest in more than one. It is important to diversify investments by creating this portfolio. Your portfolio will depend on your risk tolerance.
Growth Assets
Definition: Investments designed to grow wealth over time. They usually provide higher returns but are more volatile in the short term (values can rise or fall quickly).
Purpose: Long-term wealth creation, beating inflation.
Risk Level: Higher risk.
Examples:
Shares (Overseas & Australian) → returns come from dividends + capital gains, but prices fluctuate due to company performance and market conditions.
Property → can increase in value significantly but is subject to housing market cycles and economic conditions.
Positives
They generate income through capital gains (asset value increasing).
Best suited for younger investors who have time to recover from downturns.
Negatives
They are initially high risk, meaning that as prices fluctuate, it could result in loss
Defensive Assets
Definition: Investments designed to protect wealth and provide stable, reliable income. Returns are lower but more predictable.
Purpose: Security, capital preservation, steady income.
Risk Level: Lower risk.
Examples:
Government Bonds → fixed interest paid regularly, safe because governments rarely default.
Bank Term Deposits → guaranteed returns at a fixed rate, little to no risk of losing money.
Positives
They focus on income and stability instead of capital growth.
Best suited for older investors or retirees who want to minimise risk.
Negatives
As they mainly focus on income and stability, it takes longer to build up money
Portfolios
A portfolio is a mix of growth and defensive assets. The balance determines the risk profile:
Aggressive Portfolio (High Growth) → 80–100% in growth assets (shares, property).
Balanced Portfolio (Mix) → roughly 60% growth, 40% defensive.
Conservative Portfolio (Defensive) → 70–100% in defensive assets (bonds, deposits).
Why Mix Both?
Growth = long-term wealth.
Defensive = safety and income.
A diversified portfolio smooths out returns (if one asset drops, others may stay stable or rise).
Influences on Investment Decisions
People’s influences on their investment choices are characterised by two categories: Personal factors, which are Individual life events that change their money needs, and economic factors, which are the Conditions of the economy that affect investment performance
Personal Factors | Economic Factors |
|---|---|
Job loss – less income → less money available to invest | Recession – economy slows, share prices usually fall, businesses earn less |
Promotion – higher income → ability to invest more | Economic growth – economy expands, profits rise → investments often increase in value |
Illness/medical costs – may need to sell investments for cash | Wage growth – when incomes rise, people have more disposable income to invest |
Relocation – moving can be expensive → change in savings/investment plans | Government changes – new taxes, policies, interest rate changes can affect investment returns |
Starting a family – higher expenses → less risk-taking, more defensive assets | |
Retirement – move towards safer investments to protect wealth |
Law in Action
What Is a Crime?
A crime is an act or omission that breaks a law and is harmful to society.
If behaviour is criminal, the State (police + courts) steps in.
Criminal vs Civil Law — Comparison
Feature | Criminal Law | Civil Law |
|---|---|---|
Purpose | punish offender + protect society | resolve disputes between individuals |
Who brings the case? | the State (police / DPP) | private individual / business |
Outcome | jail, fine, community order | compensation for loss/damages |
Standard of Proof | beyond reasonable doubt | balance of probabilities |
Example | theft, assault, robbery, murder | contract disputes, negligence, property damage |
Elements of a Crime
Most crimes require two elements:
Actus Reus — the act of committing the crime
Mens Rea — the intention / guilty mind
Example:
If someone hits another person with the intention to hurt them → both elements exist → crime.
If it was purely accidental → mens rea might be missing → maybe not a crime.
Age of Criminal Responsibility
Under 10 → cannot be charged with a crime.
Age 10–14 → can only be found guilty if the prosecution can prove the child understood their actions were seriously wrong.
14 and above → full criminal responsibility (still treated differently to adults, especially in sentencing).
Burden + Standard of Proof
Burden of proof = who must prove the case → the prosecution.
Standard of proof = how convincing the evidence must be → criminal cases require proof beyond reasonable doubt.
Meaning: the court must be almost certain the accused committed the crime before finding them guilty.
Police Powers
Police have special legal powers to investigate crime. Powers include:
stop and question people who they reasonably suspect are involved in crime
search people, vehicles, and property in certain situations (with or without a warrant)
arrest a person if they reasonably suspect a crime has been or will be committed
seize evidence during searches
Police powers are not unlimited — they are controlled by laws to protect individuals.
Your Rights When Dealing with Police
If Police Stop You:
you must provide your name and address
you do not have to answer other questions
(right to silence)
If Police Want to Search You:
police usually need a reasonable suspicion
in some cases they need a warrant (signed by a court)
you can ask “What is your reason for searching me?”
If Police Want to Arrest You:
they must have a reasonable belief you committed a crime
they must tell you:
you are being arrested
why you are being arrested
You must go with police if you are arrested.
Police Questioning
When police question someone:
you have the right to remain silent
(except for basic identification details)you can say “I want to speak to a lawyer.”
you do not have to make a statement
Rights: Adults vs Young People
Group | Rights During Interview |
|---|---|
Adults (18+) | can refuse to answer most questions beyond name + address |
Young People (under 18) | must have a parent/guardian or another adult present when questioned |
Police must take extra steps to protect young people when interviewing them because young people are considered more vulnerable.
The Court Hierarchy (simplified)
Court | What it deals with |
|---|---|
Local/ Magistrates Court | minor criminal offences, small civil cases (no jury) |
District Court | more serious criminal cases (e.g. assault), larger civil cases, juries used sometimes |
Supreme Court | most serious criminal offences (e.g. murder), highest civil claims |
High Court of Australia | appeals on major legal issues, constitutional matters |
Why we have a hierarchy:
allows appeals (reviewing decisions)
each court specialises in the seriousness of matters
Legal Personnel / Roles in Court
Role | What they do |
|---|---|
Judge | runs the trial, decides the law and sentencing (in higher courts) |
Magistrate | similar to judge but in lower courts (no jury cases) |
Jury | 12 people; decide guilty or not guilty based on evidence (criminal trials only) |
Prosecutor | lawyer for the State/Government, tries to prove the accused is guilty |
Defence Lawyer | represents the accused, challenges evidence, tries to show reasonable doubt |
Witness | gives evidence; what they saw, heard or know |
Why juries are important
reflect community values
protect citizens from government power
ensure the verdict is based on evidence, not emotion
Civil vs Criminal (quick compare)
Criminal Case | Civil Case |
|---|---|
State vs person | Person vs person/group |
Goal: punish offender | Goal: fix a dispute / compensation |
Standard of proof: beyond reasonable doubt | balance of probabilities |
Example: robbery, assault | Example: property damage, contract dispute |
Purposes of Punishment
Punishment in criminal law is not just about revenge — it serves several purposes:
Retribution – making the offender “pay” for their crime.
Deterrence – discouraging the offender and others from committing crimes.
General deterrence: warns the community.
Specific deterrence: discourages the individual offender.
Rehabilitation – help the offender change behaviour and rejoin society.
Protection of society – keeping dangerous offenders away from the public.
Denunciation – society expresses its disapproval of the crime.
Types of Punishment (Sanctions)
Punishment | Description | Suitable For |
|---|---|---|
Fines | Payment of money to the court | Minor crimes |
Good behaviour bond | Young offender agrees to behave for up to 2 years; breach results in punishment | Minor youth offences |
Community service | Unpaid work for the community | Low to medium risk offenders |
Suspended sentence | Jail sentence delayed; only served if conditions breached | Medium offences |
Imprisonment | Removal from society for a set time | Serious offences |
Capital punishment | Execution (note: abolished in Australia) | Historically for most serious crimes |
Factors Affecting Sentencing
Aggravating Factors (make sentence harsher)
Prior convictions
Crime committed in front of children
Violence or use of weapons
Victim was vulnerable
Mitigating Factors (make sentence lighter)
First offence
Remorse shown
Cooperation with police
Young age or special circumstances
Young People and Sentencing
Children and adolescents are treated differently:
More focus on rehabilitation than punishment
Good behaviour bonds and community orders are common
Court may consider age, maturity, and family background
Impact of Punishment
Deterrence: prevents crime if penalties are known
Rehabilitation: reduces likelihood of reoffending
Protection: removes dangerous individuals temporarily
Justice for victims: sense that wrongdoing is addressed
What is ADR?
Alternative Dispute Resolution (ADR) is any method of resolving disputes without going to court.
It is often quicker, cheaper, and less formal than traditional court processes.
Common forms include:
Mediation – an impartial third party helps both sides negotiate a solution. The mediator cannot impose a decision.
Conciliation – like mediation, but the conciliator can suggest solutions.
Arbitration – a third party (arbitrator or judge) listens and makes a binding decision that both sides must follow.
Community Conferencing – used for young offenders; involves the child, victim, support people, and youth officers to agree on a plan.
Comparison Table: ADR Methods
Method | Role of Third Party | Decision Binding? | Typical Use |
|---|---|---|---|
Mediation | Facilitator | No | Family disputes, minor civil cases |
Conciliation | Facilitator + suggests solutions | No | Workplace disputes, consumer complaints |
Arbitration | Decides outcome | Yes | Commercial contracts, some workplace issues |
Community Conferencing | Guides discussion | Yes (plan agreed by all) | Youth justice, minor criminal cases |
Why ADR is Effective
Reduces stress compared to court trials
Cost-effective – usually cheaper than court
Faster outcomes
Encourages cooperation and understanding between parties
Can be more flexible and culturally appropriate, e.g., in Aboriginal and Torres Strait Islander communities
Limitations of ADR
Not legally binding in all cases (except arbitration or agreed community conference plans)
Requires willingness of both parties
May not work for very serious crimes or highly adversarial disputes
ADR in Aboriginal and Torres Strait Islander Communities
Often uses customary law practices
Emphasis on restoring relationships and community harmony rather than punishment
Elders or community leaders guide discussions and outcomes
What is a Contract?
A contract is a legally binding agreement between two or more parties. It creates rights and obligations that the law will enforce.
Key Elements of a Contract
Offer – one party proposes terms.
Acceptance – the other party agrees to those terms.
Consideration – something of value is exchanged (money, goods, or services).
Capacity – parties must be able to understand the contract and its consequences.
Intention – parties must intend for the contract to be legally binding.
Legality – purpose of the contract must be lawful.
Terms to Know
Deceptive and Misleading Conduct – providing false information to persuade someone to enter a contract.
Guarantor – a person who agrees to pay another person’s debt if they cannot or will not pay themselves.
Contracts and Young People
Legal Capacity: Legal capacity is a person's ability to make their own legal decisions and enter into binding agreements. It requires an individual to understand the facts of a situation, the potential consequences of their choices, and to be able to communicate their decision. Adults are presumed to have legal capacity unless proven otherwise, and capacity is specific to a given decision and can fluctuate
Minors (under 18) have limited legal capacity:
Can enter everyday contracts (e.g., buying food, clothing)
Cannot enter complex or high-risk contracts (e.g., loans, mortgages) without parental consent
If a minor enters a contract they cannot fully understand, it may be voidable (they can cancel it).
Breach of Contract
If a party fails to meet obligations, the other party can:
Seek compensation/damages
Demand specific performance (forcing them to comply)
Cancel the contract
Examples of Contract Situations
Buying a car → everyday contract, minor may need parent consent
Taking a loan → requires adult capacity or guarantor
Employment agreements → young people can usually agree, but hours/pay must comply with law
Consent
Consent must be voluntary and informed
Cannot be given if a person is:
Forced, threatened, or misled
Incapable due to age, illness, or intoxication
Importance of Contracts
Protects both parties legally
Ensures obligations are clear
Provides a mechanism for legal remedies if agreements are broken
What Are Human Rights?
Definition (Australian Human Rights Commission): Basic rights and freedoms that belong to all individuals, regardless of race, nationality, gender, or other status.
Purpose: Protect people from unfair treatment, promote equality, and ensure dignity and safety.
Examples of Human Rights Laws in Australia
Australian Human Rights Commission Act 1986 – protects human rights and investigates complaints
Racial Discrimination Act 1975 (Cth) – prohibits racial discrimination
Sex Discrimination Act 1984 (Cth) – prohibits discrimination based on sex, pregnancy, marital status, or sexual orientation
International Treaties Australia Upholds
Convention on the Rights of the Child (CRC) – protects children’s rights
International Covenant on Civil and Political Rights (ICCPR) – protects freedom of speech, religion, and fair trial
Convention on the Elimination of All Forms of Discrimination Against Women (CEDAW) – protects women’s rights
Bill/Charter of Rights
Definition: Legal document outlining fundamental rights and freedoms of individuals
Other nations with Bills/Charters: USA, UK, Canada, New Zealand
Arguments for in Australia:
Protects citizens from government overreach
Ensures equality and safety
Arguments against:
Could limit Parliament’s law-making powers
Existing laws already provide some protections
Discrimination
Occurs when a person or group is treated unfairly based on characteristics such as race, gender, age, disability, or religion.
Forms:
Direct: explicit unfair treatment
Indirect: policies or practices that disadvantage certain groups
Role of Law Enforcement & Agencies
NSW Police, AFP, ABF, ACIC, ACSC, ASIO – enforce laws, investigate crimes, protect citizens, maintain public safety
Australian Human Rights Commission (AHRC) – investigates complaints, promotes equality, and educates the public
Protecting Children
Convention on the Rights of the Child (CRC):
Protects from abuse, exploitation, and neglect
Guarantees education, health, and safety
Special legal provisions for youth:
Juvenile courts
Good behaviour bonds
Community conferencing
Comparisons
Australia | Other Countries |
|---|---|
Laws protecting children’s rights | Vary – some countries lack legal protections |
Anti-discrimination laws | Different scope; some have broader or narrower protections |
Bill/Charter of Rights | Australia does not have a federal charter; some countries do |
Human Rights and Technology
Cyberbullying: criminal and civil responses exist
Laws aim to protect victims, punish offenders, and educate the community
