Think of a stock portfolio like a shopping basket — but instead of groceries, you fill it with investments. Which items you choose, how many of each, and how you balance them determines how well you eat over time.
A well-considered portfolio is not put together randomly. It is built with a goal, a time horizon and a risk tolerance in mind.
A stock portfolio can contain:
Most private investors have a portfolio consisting mainly of mutual funds and individual stocks.
Two portfolios can deliver the same average return but have very different risk profiles. A portfolio with ten stocks in the same industry fluctuates far more than a portfolio with a hundred stocks spread across many industries and countries — even if the expected return is the same.
Spread your investments across different companies, industries and countries. If one stock falls 50%, it should not ruin your entire portfolio. A broad global index fund gives instant diversification across thousands of companies.
Decide what proportion of your portfolio should be in stocks, funds, bonds and cash. A rule of thumb: the longer your time horizon, the higher a share of stocks you can handle.
Over time some investments will grow more than others, and your portfolio drifts from its original allocation. Rebalancing means selling a little of what has grown and buying more of what has fallen — so you stick to your plan.
High management fees and frequent trading eat into your returns. A simple portfolio of low-cost index funds often beats a complex portfolio of expensive actively managed funds.
High stock allocation — 80–100%. Suitable for young investors with a long time horizon and high risk tolerance. The goal is maximum growth over time.
Typically 60% stocks and 40% bonds. A classic combination that provides growth with some cushioning during downturns.
Low stock allocation — 20–40%. Suitable for investors approaching retirement or with low risk tolerance. Prioritises preserving capital over growth.
