The Australian Stock Market 101 – All You Need to Know

In this article, we break down the AU stock market for anyone interested in exploring investment opportunities Down Under.

1. Australia market overview

Australian Stock Exchange (ASX):

The Australian Securities Exchange (‘ASX’) ranks as one of the largest stock exchanges globally by market capitalisation.

It also operates significant derivatives and commodities markets, with strength in agricultural and energy derivatives that reflect Australia's commodity-focused economy.

Key advantages for beginners include high liquidity in large-cap stocks and exposure to global commodities. However, diversification beyond resources can be critical to mitigate volatility.

What Webull provides for ASX: Equities, ETFs, and Warrants.

Cboe Australia:

Complementing the ASX, Cboe Australia is an alternative trade execution venue that operates under ASIC regulation too. However, Cboe has unique ETFs and may have faster execution on orders since it is a day-only trading exchange for ASX listed companies

What Webull provides for CBOE: Equities, ETFs and Warrants.

CHESS System:

The Clearing House Electronic Subregister System (CHESS) is unique to Australia and provides electronic settlement and registration of shareholdings. CHESS issues Holder Identification Numbers (HINs) that allow investors to sponsor their own holdings or use broker-sponsored arrangements, providing flexibility in share ownership management.

2. Trading Requirements

Before you begin trading on the ASX, understanding the basic requirements and mechanics is essential for successful market participation.

Minimum Investment:

For listed Australian stocks, your initial investment must be at least $500 worth of shares, which is referred to as a “minimum marketable parcel” (MMP). However, once you have established a minimum marketable parcel for a particular security, you can buy smaller amounts of shares for that security to top up your existing holdings subject to Webull's rules.

ETFs and warrants are not subject to the minimum marketable parcel rule on Webull.

Trading Hours:

Trading days are Monday through Friday, excluding public holidays.

1. Pre-Open: 7.00AM - 9:59AM

  • Orders can be entered but not executed.
  • The orders are queued according to price-time priority and will not trade until the market opens

2. Opening Single Price Auction (‘OSPA’): 09.59 AM - 09:59:45 AM

  • The OSPA occurs during a 15 second randomised window beginning at 9:59:00. It will commence no later than 09:59:15. The earliest transition from OSPA to continuous trading (Open) will occur at 09:59:45.
  • The ASX opening price is set where buy/sell orders are matched to find the price that maximises traded volume. It balances supply and demand to establish a fair starting price.

3. Normal Trading: 10:00AM - 4:00PM

  • ASX Trade automatically matches all trades in Price/Time Priority on a continuous basis.

4. Pre-Closing Single Price Auction (‘CSPA’): 4:00PM to 4:10PM

  • No continuous trading
  • Orders can be entered, deleted or amended before the CSPA

5. Closing Single Price Auction: 4:10PM to 4:11PM

  • ASX Trade calculates closing prices during this phase by matching buy and sell orders to find the price that maximises traded volume. If no auction occurs, it uses the last traded price during regular trading hours; if there are no trades, the prior day’s closing price is retained.

6. Post Close: 4:11PM to 4:21PM

These hours overlap with Asian markets (e.g., Japan, Hong Kong), providing opportunities for international news and events to influence opening prices.

Please refer ASX website for more details regarding trading hours.

Settlement:

Australia operates on a T+2 settlement system, meaning trades settle two business days after execution. When you buy shares, payment is due within two business days, and when you sell, you will receive proceeds within the same timeframe.

Order Durations:

Day Orders: Expire at the end of trading day if not executed.

Good-Til-Cancelled (‘GTC’): Active for up to 90 days unless executed or cancelled.

3. Order Types

Understanding different order types is crucial for executing trades according to your investment strategy and risk tolerance.

1. Market to Limit Orders:

Execute at the best available price. Any unfilled shares will rest on market at that best available price. This order type provides immediate execution for the fillable portion while offering price protection for the remaining shares.

2. Limit Orders:

Allow you to specify the maximum price you are willing to pay per share for buying and the minimum price for selling. For example, a $100 limit order to purchase CSL shares ensures you pay no more than $100 per share.

  • These orders provide price control but do not guarantee execution if the market does not reach your specified limit price. Limit orders are particularly useful in volatile markets where prices can fluctuate rapidly.

3. Stop Order:

An instruction to submit a buy or sell market order if and when the client-specified stop price hits. For example, if you hold Qantas shares and place a stop sell at $10, the order is triggered when the market price reaches $10, and a market sell order is then submitted.

4. Stop Limits Order:

A limit order will be triggered if a predefined price is reached. For the Qantas sell example, if place a stop limit order with the limit price as $9 and the stop price at $10, order will be triggered when the price reaches $10, but will only be executed at $9 or higher.

  • This provides downside protection while allowing control over execution price.

4. Corporate Actions

Corporate action refers to any event initiated by a publicly traded company that affects the shares of its stockholders.

Dividend Payments:

Dividends in Australia are paid to eligible shareholders. They are managed by Share Registries who maintain shareholder records, payments, DRPs (Dividend Reinvestment Plans) and tax documentation. Shareholders must ensure their details are current with the registry to receive payments smoothly.

Public companies use share registries to maintain shareholder records and handle administrative duties. In Australia, Computershare, Boardroom, and MUFG Corporate Markets are the primary providers.

Australian companies have a strong dividend-paying culture, with one of the highest dividend yields in the world (4.1% in the 2020s compared to 1.6% in the US). Many established companies pay bi-annual dividends. The unique feature of Australian dividends is franking credits, which represents company tax already paid on profits.

Details of franking credits are listed in the Tax Considerations section.

Dividend Reinvestment Plans (‘DRPs’):

Many Australian companies offer DRPs, allowing shareholders to automatically reinvest dividend payments into additional shares, often at a discount to market price. DRPs can be an effective way to compound returns over time:

  • To participate in DRP you will need to reach out to the companies’ Share Registry for information on how to enrol and participate.

Rights Issues:

Companies may offer existing shareholders the right to purchase additional shares at a discounted price, usually to raise capital for expansion or debt reduction. You will usually receive direct email communication from the company if you are eligible.

Stock split:

When a share undergoes a stock split, the number of outstanding shares in the market increases, but the overall value of the shares should remain the same. As a result, the price per share typically decreases at the same ratio the stock split. We will automatically update your holdings to reflect the new share quantity, ensuring a seamless transition for your equity positions.

5. Announcements

Staying informed about company announcements is essential for making informed investment decisions and understanding market movements.

Reporting Periods:

Australian companies follow a structured reporting calendar:

  • February: Half-year results (August–December).
  • August: Full-year results (July–June).

Continuous Disclosure:

Under ASX listing rule, listed companies must immediately announce any information that could materially affect their share price. This continuous disclosure regime ensures that all investors have equal access to price-sensitive information, promoting market fairness and transparency.

Types of Announcements:

Companies release various announcements including quarterly reports, management presentations and material contract announcement etc. Each type carries different implications for share price movements and investment decisions.

Market Sensitivity:

Australian markets are particularly sensitive to commodity price movements due to the heavy weighting of resource companies. Additionally, economic data from China, Australia's largest trading partner, can significantly influence market sentiment and individual stock prices across multiple sectors.

6. Share Categories & Indices

Understanding the different categories of securities and key market indices helps investors navigate the Australian market structure and benchmark performance.

Ordinary Shares:

These represent standard equity ownership in Australian companies, providing voting rights and potential dividend entitlements.

Exchange Traded Funds (‘ETFs’):

ETFs provide diversified exposure to market indices, sectors, or themes through a single security.

Key Market Indices:

  • S&P/ASX 200: Tracks the performance of the top 200 Australian companies by market capitalisation, rebalanced quarterly.
  • All Ordinaries: Provides broader market coverage of approximately 500 companies.
  • S&P/ASX 300: Encompasses the top 300 companies by market capitalisation, including smaller-cap companies.

Market Capitalisation Segments:

The Australian market is divided into large-cap (ASX 100), mid-cap (ASX 200 excluding ASX 100), and small-cap (outside ASX 200) segments. Each segment exhibits different risk and return characteristics, with small-caps typically offering higher growth potential but greater volatility.

7. Tax Considerations:

Fully franked dividends:

Include franking credits, which represent the Australian company tax already paid on by the company on their profits used to fund the dividend. Australian resident shareholders may potentially be able to use these credits to reduce their personal tax liability, making Australian shares particularly attractive for income-focused investors.

Example:

Sarah receives a $1,050 fully franked dividend from Woolworths Group (ASX: WOW) with a $450 franking credit, which means WOW has already paid company tax of $450 on the underlying profit.

  • For tax purposes, this results in $1,500 of income (the dividend plus the franking credit).
  • If her marginal tax rate is 32.5%, the tax owed on that income would be $1,500 × 32.5% = $487.5. The $450 franking credit would reduce the tax payable on the outcome to $37.50.k Please enter a stock symbol
  • In this scenario, Sarah’s franking credits reduce her tax liability from $487.50 to $37.50. The $450 franking credit effectively offsets most of the tax she would otherwise owed on her WOW dividend income.

Capital Gains Tax (CGT):

Discounts on assets held longer than 12 months, reducing taxable capital gains by 50%.

8. Key Regulations

Understanding the regulatory framework governing Australian securities markets helps investors trade confidently and comply with relevant obligations.

  • The Australian Securities and Investments Commission (‘ASIC’) serves as the primary market regulator, overseeing market conduct, licensing, and consumer protection.
  • Australian Transaction Reports and Analysis Centre (‘AUSTRAC’) is Australia’s financial intelligence agency and anti-money laundering regulator, responsible for detecting and preventing financial crimes including money laundering and terrorism financing.
  • Australian Financial Complaints Authority (‘AFCA’) is Australia's external dispute resolution scheme that handles financial service complaints when they are unable to be resolved internally. The complaint service is completely free for consumers.

9. Market Characteristics

Currency Impact:

Resource companies, which generate significant foreign currency revenues, are particularly sensitive to AUD movements against major trading partner currencies.

Commodity Sensitivity:

Australia's heavy reliance on commodity exports makes the market highly sensitive to global commodity price cycles. Economic conditions in China, Australia's largest trading partner, can significantly impact Australian resource company valuations and broader market performance. Key commodity sensitivities include:

• Iron ore: Directly tied to China's steel output and infrastructure development

• Thermal coal: Benefited in 2022-23 as EU sanctions on Russian energy forced alternative sourcing

• Lithium: Volatile due to EV adoption rates and Chinese battery maker inventory cycles

Dividend Culture:

The higher dividend payout ratios create a market focused on income generation, attracting yield-seeking investors and retirees. The dividend focus can lead to different market dynamics compared to growth-oriented markets.

Retail Investor Participation:

Self-Managed Super Fund (‘SMSF’) investors represent a significant portion of retail market participation, bringing long-term investment perspectives but also creating concentrated flows around dividend payment periods.

Market Liquidity:

While major ASX 200 companies often maintain good liquidity, smaller companies may exhibit lower trading volumes and wider bid-ask spreads.
