The trick is to know which assets to choose as there are so many options out there. With that in mind, here’s how I’d allocate my £20k annual allowance to aim for long-term wealth.

Striking a risk/reward balance

I find I’m often torn between a choice to invest in a safe and stable asset with minimal growth potential, or a high-risk, high-growth asset. On one hand, returns are low but I can sleep easy at night. On the other, I’m anxious but could net great returns.

The solution? Do a bit of both. 

An investment strategy I like is called ‘core-satellite’ investing. It involves investing a lot of money into stable options while reserving a bit extra for more risky assets. Stable options typically include funds like ETFs, investment funds, or global equity funds. These managed funds spread the investment across a wide range of assets, reducing risk through diversification. They seldom return more than 5% per year on average but have a very low risk of collapsing completely.

On the flip side, there’s individual shares in high-growth industries like tech and energy. These investments can sometimes earn up to 20% or more in a single year but are at increased risk from environmental, economic, and geopolitical factors.

Core investing

One example would be the iShares S&P 500 ETF (LSE:IUSA). It provides exposure to top-name US stocks like Microsoft, Apple, Nvidia, and Amazon. Fund manager BlackRock carefully allocates the investment across stocks on the S&P 500 index, one of the best-performing indexes in the US.

Over the past 10 years, the iShares S&P 500 ETF has delivered annualised returns of 12.48%, slightly higher than its S&P 500 benchmark. Only once in 2014 did it perform below the S&P 500 average. However, since it’s focused on a single index in the US, it is prone to any economic risk the country faces. The S&P 500 is also heavily weighted towards tech, leaving it more exposed to risks in this specific industry.

Satellite investing

Take Facebook’s parent company Meta (NASDAQ: META), for example. This mega-cap US stock has risen 631% in the past 10 years, delivering 22% annualised returns. So while this stock is also part of the iShares S&P 500, any money I invested directly into it would have netted me almost twice the returns. However, if Meta failed, all that money would be gone. However, my core investment would only take a small hit.

Meta currently has a fairly high price-to-earnings (P/E) ratio of 25 — slightly higher than the industry average but on par with similar big-tech companies. Having risen 63% in the past year (almost triple the US market) it may struggle to gain more from here. CEO Mark Zuckerberg recently invested a lot into AI, a highly speculative bet that could pay off handsomely – or crash and burn. I think it will work out well for the company but only time can tell.

This is why it’s important to always diversify! I like to keep around 60% of my portfolio in funds and 40% in individual shares.

Of course, there is no real magic involved. 

As Buffett admits himself, his success is largely due to something we all have the ability to harness: compound returns.

The snowball effect

Buffett describes the power of compound returns as similar to that of a snowball: as it rolls downhill, it grows exponentially larger and larger.

In investing, this is exhibited by an increasing degree of growth over time.

The exponential growth of compounding returns

Let’s use the iShares Core S&P 500 ETF (LSE:IUSA) as an example. This UK-listed exchange-traded fund (ETF) provides exposure to major US companies listed on the S&P 500, such as Microsoft, Apple, Amazon, and Buffett’s own Berkshire Hathaway.

The ETF is weighted towards tech stocks (30%) but also includes exposure to sectors such as financials, health care, industrials, and energy.

Over the past 10 years, the ETF provided annualised returns of approximately 12% per year. It’s worth noting that it made losses in 2018 and 2022, by -4.7% and -18.4%. It has an average price-to-earnings (P/E) ratio of 25.5 but the price-to-book (P/B) ratio of 4.44 is quite high, suggesting the shares could be overvalued.

So, based on an average 12% rate of return, if I invested £100 in the iShares Core S&P 500 ETF, I could have £112 after the first year. Does that mean after the second year I’ll have £124? And after the third, £136? 

No.

The magic of compounding returns means my total return grow even more because the initial investment now includes the accumulated returns. So after year one, I would have £112, but in year two, with £112, the returns would be £13.44, bringing my total to £125.44. In year three, the returns would be £15.05, bringing my total to £140.49.

Of course, this is just a simple example — in reality, these numbers would differ slightly due to price fluctuations throughout the year.

Time in the market

The magic of compounding returns is echoed in the popular saying ‘It’s not about timing the market, but about time in the market’.

Timing the market refers to the act of trying to buy and sell at opportune moments. This is opposed to ‘time in the market’, meaning being invested for a long period. Buying and selling frequently can be profitable for some but statistics show that usually it’s less profitable than simply staying invested for long periods.

Of course, it’s not all down to compounding returns. Experienced investors like Warren Buffett have a deep understanding of global markets and spend hours researching potential stock options.

For us lesser experienced investors, investments like the iShares Core S&P 500 ETF provide exposure to a well managed and diverse portfolio of stocks. I see it as a low-risk option that I hope will provide me with consistent and reliable returns for years to come.
