One fund, a whole portfolio
A multi-asset fund packages global shares, bonds and sometimes property and cash into a single product, then rebalances itself to keep the target mix. For a pension this is hugely valuable: you get a diversified, professionally maintained portfolio without ever having to trade or rebalance. The main decision is which risk level (equity percentage) to choose and which provider to trust.
The leading multi-asset ranges in 2026
| Fund range | OCF | Approach | UK tilt? |
|---|---|---|---|
| Vanguard LifeStrategy | 0.22% | Fixed equity bands (20-100%) | Yes (~25% of equity) |
| HSBC Global Strategy | 0.18% | Risk-targeted, global cap-weighted | Minimal |
| BlackRock MyMap | 0.17% | Risk-targeted, volatility-managed | Minimal |
| L&G Multi-Index | 0.31% | Risk-rated 1-7, actively allocated | Moderate |
| Fidelity Multi Asset Allocator | 0.20% | Index-based, fixed bands | Moderate |
LifeStrategy is the best known and the simplest - you just pick an equity percentage. Its quirk is a deliberate UK overweight of about 25% of the equity portion, which has lagged a cap-weighted approach recently. HSBC Global Strategy and BlackRock MyMap avoid that tilt, follow global market weights, and cost a touch less.
Fixed-band versus risk-targeted
The ranges split into two styles. Fixed-band funds (LifeStrategy, Fidelity Allocator) hold a set equity percentage no matter what markets do - simple and transparent. Risk-targeted funds (HSBC, MyMap, L&G) aim to keep volatility within a band, adjusting the mix as conditions change. Neither is clearly better; fixed-band is more predictable, risk-targeted is smoother in theory.
- Want maximum simplicity: Vanguard LifeStrategy at your chosen equity level.
- Want lowest cost and no UK tilt: HSBC Global Strategy or BlackRock MyMap.
- Want active oversight: L&G Multi-Index, at a higher 0.31%.
What is inside a multi-asset fund?
Lift the lid on a typical multi-asset fund and you find not one investment but dozens, usually built from the provider's own index trackers. A LifeStrategy 60% fund, for example, holds a global equity tracker, a UK equity tracker, several government and corporate bond trackers, and sometimes inflation-linked bonds, all in fixed proportions. This "fund of funds" structure is what gives you instant diversification across thousands of underlying holdings in a single purchase. The provider handles all the buying, selling and rebalancing internally, which is why the OCF you pay covers the whole package, not just one fund.
The rebalancing advantage
Left alone, a portfolio drifts: after a strong run for shares, your equity weighting creeps up and so does your risk, often just before a fall. A multi-asset fund automatically trims what has risen and tops up what has lagged, keeping your risk level steady and quietly enforcing the discipline of "sell high, buy low". Doing this yourself across several funds requires regular attention and the emotional strength to sell winners. Outsourcing it to the fund is one of the most underrated benefits of the multi-asset approach, particularly for savers who would otherwise never get round to it.
Verdict
Vanguard LifeStrategy remains the easiest multi-asset pension fund to understand and use, but HSBC Global Strategy and BlackRock MyMap edge it on cost and avoid the UK overweight. Any of the three makes an excellent single-fund pension core.
