3 Tips For Building a Diversified Portfolio Within a GIA

The United Kingdom has gained a reputation for preferring saving over investing, but times appear to be changing. 

According to a recent survey, more than one in five (21%) of adults say they are likely to start a small regular investment of £10 to £50 in 2026. 

Interest in investing is higher among young people, with 41% of Gen Z and 33% of Millennials claiming that they will consider investing on a regular basis this year. 

This indicates that GIAs are undergoing a popularity boom. But if you’re looking to get started with a General Investment Account, what key considerations should you keep in mind?

One of the most important factors to remember is that investing is riskier than saving, because the stocks and other equities you hold within your portfolio can go down as well as up. 

Although recent years have seen both the S&P 500 in the US and FTSE 100 in the UK far outpace the level of money that can be made through high-interest savings accounts, it’s always important to diversify your holdings to ensure that you’re protected against downturns in certain industries. 

It can be tempting to fill your GIA with tech stocks because they’ve gained the most recently, but any market stresses could see you lose more money than if you’d picked a more mixed range of stocks to hold. 

But how can you build a well-rounded portfolio? Let’s take a look at three essential tips for building a diversified portfolio within your GIA: 

1. Look at Global Index Funds and ETFs

The great thing about GIAs is that they can incorporate different funds when building a portfolio. Global index funds and exchange-traded funds (ETFs) are great because they can do your diversification work for you. 

Rather than manually buying individual stocks and paying extra dealing fees, you can use low-cost index funds or ETFs to diversify your portfolio on an international scale. This means that you’ll not only have better protection against industry downturns but also geographical risks like localised economic or geopolitical pressures. 

To action this, look at major world indices like the MSCI All Country World Index (ACWI) or FTSE All-World to expose your GIA to a wide range of companies throughout developed and emerging markets, spreading your geographic risk without having to manage individual overseas assets. 

2. Blend Mixed Income and Real Assets 

Stocks are great for providing long-term growth for your portfolio, but it’s important to take measures to protect against volatility. This means that you should spread your money across different asset classes. 

Allocate some of your portfolio to fixed-income assets like UK Gilts or global government bonds and real assets like REITs or gold. 

Diversification means more than spreading your ownership of different stocks, and incorporating various types of assets means that when markets dip, you’re in a better position to retain the value of your portfolio. 

Assets like bonds and real assets typically hold their value better than stocks during a market downturn and are more capable of providing a steady income to smooth out your portfolio’s long-term returns. 

3. Keep Tax Efficiency in Mind

Unlike ISAs or your pension, GIAs are subject to tax. But this doesn’t have to mean that you can’t make your portfolio more tax-efficient by becoming more strategic with your holdings. 

For instance, if you prioritise accumulating funds like ETFs and index funds, the dividends you receive are automatically reinvested rather than distributed, meaning that you won’t incur dividend tax on them. 

You can also adopt a ‘Bed and ISA’ strategy where you transfer £20,000 of your GIA investments into an Individual Savings Account (ISA) at the beginning of each tax year to help reach your annual tax-free allowance.

By using this strategy to shift any dividend-paying stocks to a Stocks and Shares ISA, you can continue to hold a diversified portfolio while making sure you pay as little tax as possible on the money you earn. 

Making the Most of Your GIA

General Investment Accounts are a great way to earn money on your terms, and by taking some careful measures, your portfolio will be more resilient when it comes to market downturns, and the ability to incorporate funds means that you have a better chance to diversify your holdings across industries and geographies automatically. 

Although GIAs aren’t as tax-efficient as ISAs, there are no limits on the amount of money you can deposit into your account, making it far more effective to build your wealth over time. 

By taking the right measures to diversify your portfolio, it’s easier to grow your wealth safely and sustainably into the future.
