Investing in shares represents one of the most accessible ways for Australians to build wealth and participate in the country’s economic growth. Whether you’re looking to supplement your superannuation, generate passive income, or achieve long-term financial goals, learning how to buy shares is an essential skill when it comes to investing.
The Australian Securities Exchange (ASX) provides a regulated marketplace where investors can purchase ownership stakes in publicly listed companies. From established blue-chip stocks to emerging growth companies, the ASX offers diverse investment opportunities across various sectors including mining, banking, technology, and healthcare. That’s all well and good, but how do you get started?
Understanding Share Trading Fundamentals
Before diving into how to buy shares, it’s crucial to understand what you’re actually purchasing. When you buy shares, you’re acquiring partial ownership in a company, and that gives you to a portion of the company’s profits through dividends (if the company chooses) and potential capital growth as the share price increases over time.
Share prices fluctuate based on numerous factors including company performance, market sentiment, economic conditions, and investor demand. These price movements create opportunities for both gains and losses, making it essential to approach share trading with proper knowledge and preparation. Fundamental analysis involves breaking down a company’s operations into figures you can use to compare, and value them.
The Australian share market operates during specific hours, typically from 10:00 AM to 4:00 PM AEST on weekdays, with pre-market and after-hours trading available through some brokers. Whilst markets are not open on the weekend, some brokers will allow you to open orders during closed periods, but understanding these trading windows helps you plan when to execute your ideas, as placing orders outside of hours can have an impact on price.

Conducting Thorough Research
Successful share investing begins with comprehensive research into which shares might be the best fit. This research phase is fundamental to making informed decisions about how to buy shares that align with your investment objectives and risk tolerance. Start by examining a company’s financial statements, including profit and loss statements, balance sheets, and cash flow statements. These documents reveal crucial information about the company’s financial health, profitability trends, and debt levels.
Pay particular attention to revenue growth, profit margins, and return on equity metrics. We have a share screener you might find useful that highlights the top ASX companies, along with the respective data so you can dig down into the detail, or compare shares on more simple metrics like 1 year return, or P/E ratio.
Industry analysis forms another critical component of your research process. Understanding the sector dynamics, competitive landscape, and future growth prospects helps you evaluate whether a company is well-positioned within its market.
If you want to dig further, company management quality could well play a role in how the future shapes up for a stock. Think Elon Musk, and the role he has had on his particular companies, like Tesla as an example. Research the leadership team’s track record, strategic vision, and corporate governance practices. Market sentiment and analyst opinions offer additional perspectives, but remember that these represent opinions rather than guarantees, and analysts can also change their rating on any given day depending on what is taking place fundamentally. Professional analyst reports can provide detailed industry knowledge and financial modelling, but if you are able, it is always a good idea to carry out some of your own analysis rather than relying solely on external recommendations.
If that all sounds a lot more complicated than you planned, you can consider more broad based investment products like ETFs, that are more diverse, and are designed to follow particular markets or sectors more broadly. This can help provide exposure to the share market, without having to select the shares individually.
Determining Position Sizing
If you have chosen your shares to buy, the next step you need to consider is how much you are planning to invest. Position sizing is just that.
This decision directly impacts your portfolio’s risk profile and potential returns, and proper position sizing helps protect your capital while allowing for meaningful growth opportunities. A common approach involves limiting individual positions to a specific percentage of your total portfolio, typically between 2% and 10% depending on your risk tolerance and diversification strategy. This approach prevents any single investment from disproportionately affecting your overall portfolio performance.
Consider your investment timeframe in this process, as long-term investments might warrant larger positions in high-conviction stocks, while shorter-term trades typically benefit from smaller, more manageable position sizes that allow for quicker adjustments. Dollar-cost averaging represents another effective strategy for position sizing, particularly for beginners learning how to buy shares. This approach involves making regular, fixed-dollar investments regardless of share price fluctuations, helping to smooth out market volatility over time.
Setting Up A Share Dealing Account
Now you are ready with the shares you want to buy, and the position size, you need somewhere to buy them. The first practical step you will need to take to buy shares involves opening a brokerage account with a licensed Australian financial services provider. Online brokers have become increasingly popular due to their competitive fees, user-friendly platforms, and comprehensive research tools. When selecting a broker, consider factors such as brokerage fees, platform functionality, research capabilities, customer support, and the types of markets you can access.
Many brokers offer different account types, but if you are mainly looking to invest in shares, most of the bells and whistles that might be essential for active traders won’t be as important.
The account opening process typically requires providing identification documents, proof of address, tax file number, and completing a risk assessment questionnaire to comply with Australian financial regulations. Don’t be put off by this, it is standard procedure, and the broker is required to request these things. Always verify your chosen broker’s licensing and regulatory status before opening an account, and if you want a list of some of the top rated brokers along with regulation numbers, you can check out what our team think.
Placing Your Trade Order
Once you’ve completed your research and determined your position size, the next step involves placing your trade order through your broker’s platform. Understanding different order types helps ensure your trades execute according to your intentions and risk parameters.
Market orders represent the simplest order type, instructing your broker to buy shares immediately at the current market price. While market orders typically execute quickly, they may result in paying slightly more than expected during volatile market conditions.
Limit orders allow you to specify the maximum price you’re willing to pay for shares. This order type provides price control but may not execute if the share price doesn’t reach your specified level. Limit orders are particularly useful when buying shares in less liquid stocks or during volatile market periods.
Stop-loss orders help manage risk by automatically selling shares if the price falls to a predetermined level. While not always necessary for long-term investors, stop-loss orders can protect against significant losses in volatile positions.
Good-till-cancelled (GTC) orders remain active until you cancel them or they execute, while day orders expire at the end of the trading session. Choose the appropriate order duration based on your investment strategy and market outlook.
Confirming Trade Execution
After placing your order, monitoring the execution process ensures your trade completes as intended. Most modern trading platforms provide real-time updates on order status, from pending to partially filled to completely executed. Trade confirmations typically include essential details such as the number of shares purchased, execution price, brokerage fees, and settlement date.
Settlement in the Australian market typically occurs on T+2 basis, meaning ownership transfers and payment processing complete two business days after the trade date. During this period, most online brokers will still allow to sell the shares, although funds will take those 2 working days to clear back into your account if you are looking at making a withdrawal. It is advisable to keep a detailed records of all your share transactions for tax purposes, as reporting capital gains and dividend income is an important part of the process.
Building An Investment Strategy
Learning how to buy shares effectively extends beyond individual transactions to developing a comprehensive investment strategy. Consider factors such as diversification across different sectors and company sizes, regular portfolio reviews, and maintaining discipline during market volatility.
Successful share investing requires patience, continuous learning, and emotional discipline. Market fluctuations are normal, and maintaining a long-term perspective helps avoid costly emotional decisions during temporary market downturns. Consider starting with a small portfolio and gradually increasing your investments as you gain experience and confidence. This approach allows you to learn from mistakes without risking significant capital while building the knowledge and skills necessary for successful investing long term.
