The UK’s most powerful investment funds, from M&G to Invesco to Vanguard

Updated on 12 November 2018 | 0 Comments

With billions of pounds under management, a handful of investment funds have grown to dominate the market. But, as Rob Griffin explains, you should think twice before investing.

They are the investment industry’s equivalent of football bosses José Mourinho and Pep Guardiola. Fund management superstars at the peak of their powers.

These investors have day-to-day control over billions of pounds that can be used to buy exciting, innovative companies from around the world.

It’s a high-pressure job that puts them under constant scrutiny. Their performance – or lack of it – is on display in the statistics for everyone to see.

If they make the right decisions, their clients will enjoy bumper profits. If they get it wrong, they can wipe out someone’s life savings virtually overnight.

So, should you invest in one of these powerhouse funds?

Why are they so large?

In simple terms, they have grown to this size because they are popular with investors and there are several reasons why this may be the case.

For some, it’s due to delivering great returns, while for others it’s having strong marketing teams, according to Darius McDermott, managing director of Chelsea Financial Services.

“A fund may have also been in a ‘fashionable’ asset class, or with a fund manager who is very popular for some reason,” he says.

While there are constant – and totally fair – warnings not to base decisions on past performances, these nevertheless often influence people’s desire to invest in them.

“If something has performed well, there is the possibility it will do so in the future and that the strategy has worked, but that’s not always the case,” he adds.

Which funds have become the biggest?

UK investors’ favoured funds don’t necessarily have the same focus. Some will invest in global equities, while others embrace a variety of asset classes.

However, they share one or more key characteristics, according to Patrick Connolly, a chartered financial planner at Chase de Vere.

“These can be having strong performance records, a respected manager, low charges, or strong channels of distribution,” he explains.

Typically, it’s only so-called passive funds that can compete in terms of charges because they replicate particular indices, rather than being run by an active manager.

This means the person at the helm has less freedom to search the market for exciting opportunities as they need their fund to buy companies on the index itself.

“Distribution channels are also hugely important to fund sizes,” says Connolly. “All funds with aspirations to be larger need to be available on the main investment platforms.”

Having such a presence can boost inflows if they appear on the best buy lists of the largest fund sellers.

“We’ve seen, time and again, how the funds promoted by Hargreaves Lansdown attract high levels of new investments,” he adds.

Pros and cons of large funds

A fund’s size can make it powerful because it usually owns a decent percentage of individual companies.

As meaningful shareholders, this gives the fund’s managers a strong voice. “They can potentially influence management teams to do better,” points out Chelsea’s McDermott.

However, there are potential downsides. While many large funds have grown in popularity due to strong past performance figures, it doesn’t mean this will continue.

“Funds can get too big, the manager has to change their strategy to deal with the extra assets, and then it doesn’t do so well,” he adds.

It also depends on what the fund invests in, according to Patrick Connolly, a chartered financial planner at Chase de Vere.

“It may be easy to buy and sell the largest companies listed on the main stock markets, but this becomes more difficult if you’re investing in smaller companies or less liquid markets, such as the emerging economies,” he explains.

This is why it’s important to understand how funds are managed – and to constantly monitor them to ensure they’re meeting your needs.

“There are very few funds which become much larger and then continue to maintain the impressive performance which made them popular in the first place,” adds Connolly.
