Coronavirus (COVID-19) update 

The coronavirus outbreak has caused considerable volatility in the stock markets, potentially impacting your investments.

At times like this, it's important not to make any quick decisions when it comes to selling or buying investments. Do your research and beware of investment scams.

You can find the latest updates and answers to your questions in our how to protect your investments story.

You can find out more of the latest updates and advice on our dedicated Which? Coronavirus information hub.

1. Choosing the right investment products

One of the last steps you'll take once you've decided on your ideal portfolio will be how to populate it with actual investments. 

The easiest way of doing this is through investment funds, such as unit trusts, open-ended investment companies (Oeics), investment trusts and exchange traded funds. They're cost-effective, and allow you to further spread risk, compared with investing directly.

Remember, the management costs of your investments can have a big impact on their performance. We suggest you use low-cost tracker funds to fill up your portfolio, although some assets, such as property, may be better suited to higher-cost, actively managed funds.

2. Buying investment products for your investment portfolio

If you decide to invest alone, without the help of a financial adviser, you can cut the cost of investing in funds by using a fund supermarket or discount broker. These are hubs that allow you to buy investment products and monitor their performance in a one-stop shop.

Because you're doing all the hard work of picking your investment, fund supermarkets and discount brokers reduce the commissions that are payable in certain types of investment funds. Cutting these charges can have a significant impact on the performance of your investment portfolio over the long-term.

3. Rebalancing your investment portfolio each year

You’ll need to re-assess and rebalance your portfolio annually. Rebalancing is the process of bringing your portfolio back to its original asset allocation. This is necessary because, over time, your investments may fall out of sync with your original asset allocation; this tends to happen when one asset, usually equities, grows quicker than the others.

For example, if UK equities represent 20% of your portfolio at the beginning of the year, but have grown in value to represent 30% at the end, you’ll need to sell some of your UK equity holding and purchase more of an asset that’s underweight to get back to your original asset allocation.

Try to resist the temptation to tinker with your portfolio, and rebalance after six months or a year. The Money Advice Service has some advice on assessing the performance of your investments
