Low-cost index tracker funds have become the default recommendation in a great deal of investment writing, and for good reason — cost is one of the few things about a fund's future that can actually be known in advance, while future performance cannot. But "cheaper is usually better, all else being equal" is not quite the same as "cheaper is always better regardless of circumstances", and there are specific, reasonable situations where a higher-fee actively managed fund might still be a sensible part of an investor's thinking.
Why cost matters so much in the first place
As covered in the companion article on the OCF, fees compound over time in a way that is entirely predictable and applies regardless of market conditions — a fund's charges are deducted whether markets rise or fall. This is why cost is often treated as a starting-point filter when comparing funds pursuing similar strategies. It does not, however, mean that cost is the only factor worth considering.
Circumstances where a higher-fee fund is sometimes considered
Access to a specialist or niche market
Some market segments — certain emerging markets, small-cap companies, or specialist sectors — are less efficiently priced and less well covered by index providers, or lack a well-established, low-cost tracker option altogether. In these areas, some investors consider that active management, employing analysts who research individual companies directly, may have a more meaningful role to play than in a highly efficient, well-covered market like large-cap US or UK equities, where index trackers are numerous and very cheap.
A specific investment approach not available via a tracker
Certain funds pursue an approach that inherently cannot be replicated by an index — for example, a fund with an explicit focus on capital preservation, a specific income target, or exclusion criteria based on particular ethical or sustainability considerations that don't map onto a standard index. An investor whose priority genuinely includes one of these features, not just raw cost, may reasonably weigh a higher-fee fund that delivers it against a cheaper tracker that does not.
Diversification away from a market-cap-weighted approach
Standard index trackers are usually market-capitalisation weighted, meaning the largest companies make up the largest share of the fund. Some investors are specifically seeking an approach that weights differently — by dividend yield, by company size, or by other factors — which may not be available as a low-cost mainstream tracker in every case, though low-cost "factor" or "smart beta" tracker funds pursuing some of these approaches do increasingly exist.
A long track record of consistent, risk-adjusted performance net of fees
Some actively managed funds have delivered returns that, even after their higher fees, have compared reasonably with relevant benchmarks over long periods. Past performance is not a reliable guide to future returns, and the number of funds that persistently outperform after fees over long periods is a minority — but an investor doing their own research may reasonably conclude that a specific fund's approach and track record justify closer attention, provided this is treated as one input rather than a guarantee.
A worked hypothetical example: what a higher fee needs to overcome
Suppose an investor is comparing a tracker fund with a 0.10% OCF against an actively managed fund with a 0.90% OCF, both held for 10 years on a £40,000 investment, with the tracker assumed to grow at a hypothetical 6% a year before charges.
| Fund | OCF | Net growth assumption | Value after 10 years (hypothetical) |
|---|---|---|---|
| Tracker fund | 0.10% | 5.90% | ≈£70,900 |
| Active fund (fees only, same gross return assumption) | 0.90% | 5.10% | ≈£65,600 |
For the active fund to match the tracker's outcome in this hypothetical scenario, its underlying investment decisions would need to generate roughly an extra 0.8 percentage points of gross return per year, on average, simply to offset the fee difference — before it could be said to have added any further value beyond that. This illustrates why a higher-fee fund needs to clear a real, quantifiable hurdle, not just deliver "good" performance in absolute terms.
Questions worth asking before considering a higher-fee fund
- Is there a genuinely low-cost tracker or passive alternative that achieves a similar underlying exposure, and if so, what specifically would be given up by not using it?
- Does the fund's stated approach clearly justify active management (illiquid or under-researched markets, a specific mandate that can't be indexed), or is it an actively managed fund in a highly efficient, well-covered market segment?
- Has the fund's performance, net of all fees, been assessed over a full market cycle rather than a single strong year?
- What is the total combined cost, including the platform charge, once the fund's OCF is added — as covered in the article on platform fee plus fund fee total cost?
The role of survivorship bias and fund selection difficulty
One challenge specific to evaluating active funds is that the funds an investor sees performing well today are, by definition, survivors — funds that performed poorly over long periods are often merged into other funds, closed, or renamed, meaning historical comparisons of "the active funds available today" versus an index can overstate how active management has performed as a whole, since the underperforming and closed funds have effectively disappeared from the sample being viewed. This is sometimes called survivorship bias, and it's a reason why broad studies looking at all active funds that existed at a given starting point, including those that later closed, tend to show a less favourable picture of active management overall than looking only at currently available funds with strong track records.
The practical difficulty of identifying likely future outperformers in advance
Even setting survivorship bias aside, the harder practical problem is that identifying, in advance, which specific active fund will outperform over the next 10 or 20 years is genuinely difficult — a fund's strong past performance is not a reliable indicator that the same performance will continue, since manager changes, strategy drift, and changing market conditions can all affect a fund's future results in ways that are not predictable from historical data alone. This is precisely why some investors choose to treat cost as the primary decision factor for a large "core" portion of their portfolio, while reserving a smaller "satellite" allocation, if desired, for higher-conviction active fund choices where the potential impact of getting the selection wrong is more contained.
Fund manager tenure and consistency of approach
Where an investor is specifically evaluating an active fund on the strength of its historical performance, it's worth checking how much of that track record occurred under the current fund manager, since a change in manager can represent a meaningful change in the fund's actual investment process, even if the fund's name, strategy description, and OCF remain unchanged. A long track record achieved under a manager who has since left is a materially weaker piece of evidence for a fund's likely future performance than the same track record achieved under a manager still in place.
A balanced view
None of this amounts to a claim that active management "doesn't work" or that index tracking is always the superior approach — both are legitimate, widely used strategies, and many diversified portfolios combine elements of both. The educational point is simply that a higher fee is a real, certain, compounding cost that needs to be weighed consciously against what it might realistically buy, rather than assumed away or ignored because a fund has a strong recent track record.
Blending active and passive within a single portfolio
Rather than treating this as a binary all-active or all-passive choice, many investors build a portfolio that combines both — for example, using low-cost tracker funds for well-covered, efficient markets such as large UK and US equities, while allocating a smaller portion to actively managed funds in markets or strategies where they specifically believe active management may have more to offer, such as certain smaller company or specialist sectors. This "core and satellite" style approach, covered in more detail in a companion article on building a core and satellite portfolio, allows an investor to keep the bulk of their overall cost low while still expressing a considered view in a more targeted, smaller part of the portfolio, rather than committing the whole portfolio to either extreme.
Setting realistic expectations before choosing an active fund
Where an investor does decide, after careful consideration, to include a higher-fee active fund in their portfolio, it's worth setting realistic expectations from the outset: that the fund may underperform a comparable low-cost tracker in any given year, that this alone doesn't necessarily mean the original reasoning for choosing it was wrong, and that judging the decision fairly requires looking at performance net of fees over a reasonably long period (several years at minimum) rather than reacting to short-term results in either direction. Deciding in advance what would actually change the original decision — for example, a sustained multi-year period of underperformance against a clearly stated benchmark, or a change in fund manager — can help avoid either abandoning a reasonable long-term choice too early because of short-term noise, or persisting with an unsuitable fund for too long simply out of inertia.
Key takeaways
- Cost is one of the few certain, predictable factors about a fund's future, which is why low fees are often treated as a sensible starting filter.
- Specialist or niche markets, non-standard investment approaches, and funds with features that can't be replicated by an index are situations where active management is sometimes considered to have a more meaningful role.
- A higher-fee fund needs to generate meaningfully higher gross returns just to match a lower-fee alternative's net outcome — the fee difference is a real hurdle, not a rounding error.
- Past performance, even net of fees, is not a reliable guide to future returns and should be treated as one input among several, not a guarantee.
- Weighing a higher-fee fund is a matter of personal judgement based on specific circumstances, not a universal rule in either direction.
