How to choose a fund: five checks in order

There are many funds, they differ in the details, and it is the details that decide the result.

First: what is inside

The holdings and the rules for forming them. The name describes the intention; the asset structure describes reality — What is actually inside a fund.

Second: what ownership costs

The management fee plus the fund's other expenses. Deducted daily, invisible in a broker statement, and substantial once accumulated over a decade.

Third: how closely it tracks

The actual lag behind the stated benchmark over several years. A lag of roughly the fee is normal; a materially larger one is a question — Tracking error: how far a fund trails its index.

Fourth: liquidity and spread

The unit's daily turnover and the width of the spread. A fund cheap on fees but wide on spread can work out more expensive over a short holding period — Liquidity: noticed only once it runs out.

Fifth: the price-to-assets gap

How far the exchange price of a unit diverges from net asset value. A systematic premium means overpaying on every purchase.

The tax frame

If the horizon is long, check whether ownership relief applies and how the fund is taxed — Tax on funds: where the relief works and where it does not.
