Top 10 best-selling ISA and SIPP funds in April

April was a stellar month for the stock market. Despite tension in the Middle East, high oil prices, and low consumer confidence, the S&P 500 jumped by 10% to hit a record high. The rally was fuelled by a bumper earnings season - particularly for Big Tech.

Personal investors were paying attention. Having piled into cash funds in March, Fidelity’s SIPP and ISA customers prioritised growth in April, seeking out global tracker funds, generous dividend payers and technology stocks.

Read on for the top 10 ISA and SIPP funds in April, or click on the below for the best-selling investment trusts and ETFs.

Big Tech

Financial results from the world’s biggest tech firms came thick and fast in April. Profit growth was impressive, and investors were enthusiastic - despite plans to invest huge sums in artificial intelligence.

This could explain why Polar Capital Global Technology was a best-seller last month. This actively managed fund invests across the technology sector, holding everything from semiconductor stocks to electrical equipment makers. Over 60% of the fund is invested in the US and Canada, but it also offers some hefty exposure to Asia Pacific.

Top holdings include giants like Nvidia, Alphabet and TSMC, but the 12-person investment team looks slightly further down the food chain as well.

World trackers

World tracker funds were also popular last month, with Fidelity Index World Fund, Vanguard FTSE Global All Cap Index, Legal & General Global Equity Index Fund and HSBC FTSE All World Index all making it onto the best-sellers list.

These tracker funds let you invest in both developed and emerging markets for a relatively low fee. They also offer plenty of exposure to the tech sector, given the ‘Magnificent 7’ represent about a fifth of the global market.

It is easy to think that all tracker funds are the same - but they’re not. The Vanguard fund is more diversified than many, offering exposure to developed and emerging markets. Its top 10 holdings represent just over a fifth of the total portfolio. In contrast, the Fidelity fund focuses exclusively on developed markets, and its top 10 holdings represent 27% of the total portfolio. The HSBC and L&G funds sit somewhere in between.

A big part of the appeal of all these funds, however, is their price. They allow you to ride the ups and downs of the global market for an ongoing charge of between 0.12% and 0.23%.

Dividend giants

Personal investors are on the hunt for dividends too. The Fidelity Global Dividend Fund and Artemis Global Income Fund are some of the most consistently popular funds on the Fidelity platform.

The former is an actively managed fund that targets companies with healthy yields underpinned by rising income. The portfolio invests across a variety of sectors and geographies, offering a good level of diversification (the US represents just a quarter of the portfolio). It also aims to deliver less volatility than the wider market, which may be attractive in today’s unpredictable world.

The Artemis Global Income Fund has a different focus. It is heavily weighted towards the financial sector and has some chunky exposure to emerging markets. Like the Fidelity fund, however, it has limited its US holdings and is looking for generous dividend yields. Free cash flow is its key metric, and it has delivered explosive growth over the past 12 months.

The fund also stands out for its focus on lesser-known companies. While familiar names like Samsung and BAE Systems feature among its top holdings, others - such as Hanwha Aerospace - are less widely covered in the UK.

Emerging markets

Emerging market stocks are having an excellent year. Although they wobbled during the early stages of the Middle East conflict, they have since rebounded, helped by a handful of Asian semiconductor stocks such as South Korea’s Samsung and SK Hynix.

Lazard Emerging Markets Fund - which Fidelity’s investment director Tom Stevenson named as one of his fund picks in January - is a popular choice this year. It mainly invests in Asia and Latin America and looks for companies that are cheaper than the market but with better fundamental prospects. It aims to outperform the MSCI Emerging Markets Index with less volatility.

Cash

After dominating flows in March at the height of ISA season, cash funds fell sharply in the April rankings. However, the Royal London Short Term Money Market Fund remained popular among ISA and SIPP investors.

Money market funds roughly track UK interest rates. They invest in different forms of short-term debt, including Treasury bills and certificates of deposit. Crucially, the holdings are very high quality, liquid, and diversified. This means the funds themselves liquid, stable and low risk - albeit slightly higher risk than a traditional savings account.

The Bank of England kept rates on hold at 3.75% in April despite a rise in inflation triggered by the conflict in the Middle East.
