Tom’s picks

In January, Fidelity’s investment director Tom Stevenson published three fund picks for 2026: Dodge & Cox Worldwide - Global Stock, Fidelity Special Situations, and Lazard Emerging Markets. Personal investors were clearly paying attention, as all three are best-sellers this year.

The funds offer different ways to diversify your portfolio away from Big Tech. Dodge & Cox is a value-oriented fund with a wide range of holdings. Only half the portfolio is invested in the US - well below a neutral weighting - while Europe, the UK and emerging markets are over-represented.

Its portfolio is fairly concentrated with under 100 holdings, and it is at the riskier end of the spectrum. As such, it is more suitable for investors with a long time-horizon of ten years or more.

Fidelity Special Situations also hunts for cheap stocks, but it has its eyes squarely on the UK market. Fund manager Alex Wright has years of experience seeking out London-listed companies going through tough times. The portfolio is skewed towards medium- and smaller-sized businesses, but big names like Lloyds and AstraZeneca feature among its top holdings too.

Last up: Lazard. Lazard Emerging Markets mainly invests in Asia and Latin America. It looks for companies that are cheaper than the market but with better fundamental prospects. Emerging markets were among the best performing equity assets last year, but conflict in the Middle East is weighing on the region’s performance recently.

Growth at a reasonable price

‘Growth at a reasonable price’ - or GARP - is also proving popular with ISA and SIPP customers. In simple terms, GARP funds try to find companies that are growing faster than the market but which are also cheaper than their peers. The strategy has taken off in recent years.

Three GARP funds run by Artemis - Artemis SmartGARP European, Artemis SmartGARP Global Emerging Markets, and Artemis SmartGARP UK - are best-sellers this year. All have had a fantastic couple of years, posting gains well ahead of their respective benchmarks.

For Artemis, GARP involves running a digital stock screen every day, which incorporates millions of data points. This ‘systematic’ approach is designed to remove behavioural biases. There is also a layer of human oversight, however, with fund managers reviewing the most promising-looking companies.

Cash is back

Investors steered away from money market funds in early 2026. However, as equities wobble and rate cuts stall, customers are seeking out cash once again. The Fidelity Cash Fund is proving a favourite - particularly for SIPP customers. 

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 Fidelity Cash Fund currently yields 3.8%. Please note this is not guaranteed.

For a long while, investors were expecting the Bank of England to cut interest rates in 2026. Conflict in the Middle East has changed the playbook, however, and markets now expect rates to rise instead. Higher interest rates can make cash funds significantly more attractive.

Dividend giants

Investors are seeking income elsewhere too. The Fidelity Global Dividend Fund and Artemis Global Income Fund are some of the most consistently popular funds on the Fidelity platform - and 2026 is no exception. 

The former is an actively managed fund that targets companies with healthy yields underpinned by rising income. The portfolio is spread across a variety of sectors and geographies, offering a good level of diversification (the US represents less than 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. Indeed, it actively tries to find companies that are not held by similar funds. It is heavily weighted towards the financial sector and has some chunky exposure to emerging markets, including South Korea (Samsung is the top holding as of January). Like the Fidelity fund, however, it has limited its US holdings and is looking for generous dividend yields.

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

Global trackers

World tracker funds are a core part of many portfolios. This year, the Vanguard FTSE Global All Cap Index, the HSBC FTSE All World Index and Fidelity Index World are proving particularly popular. 

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 fund sits somewhere in between.

A big part of the appeal of all three tracker 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%.

Important information - investors should note that the views expressed may no longer be current and may have already been acted upon. Before investing into a fund, please read the relevant key information document which contains important information about the fund. Eligibility to invest in a SIPP or ISA and tax treatment depends on personal circumstances and all tax rules may change in the future. Withdrawals from a SIPP will not normally be possible until you reach age 55 (57 from 2028). Overseas investments will be affected by movements in currency exchange rates. Investments in emerging markets can be more volatile than other more developed markets. Reference to specific securities should not be construed as a recommendation to buy or sell these securities and is included for the purposes of illustration only. There is a risk that the issuers of bonds may not be able to repay the money they have borrowed or make interest payments. When interest rates rise, bonds may fall in value. Rising interest rates may cause the value of your investment to fall. An investment in a money market fund is different from an investment in deposits, as the principal invested in an money market fund is capable of fluctuation. Fidelity’s money market funds do not rely on external support for guaranteeing the liquidity of the money market funds or stabilising the NAV per unit or share. An investment in a money market fund is not guaranteed. This information is not a personal recommendation for any particular investment. If you are unsure about the suitability of an investment you should speak to one of Fidelity’s advisers or an authorised financial adviser of your choice.
