The Siaml Pension ETF 40

Most Nigerian equity ETFs track indices based on one criterion: market capitalisation. The 30 or 40 biggest companies by market cap, ranked and weighted accordingly. The NGX Pension 40 Index takes a different approach. It is constructed to reflect the equity securities most commonly and consistently held by Nigeria's institutional Pension Fund Administrators — the regulated entities that manage the retirement savings of Nigerian workers under the Contributory Pension Scheme. By tracking how pension institutions collectively allocate their equity portfolios, the index embeds a degree of institutional due diligence into its construction.

Why would a pension fund's equity allocation look different from a pure market-cap ranking? Several reasons. Nigerian PFAs operate under investment guidelines set by the National Pension Commission (PenCom) that restrict maximum exposure to individual securities and sectors. PFAs tend to favour large, liquid, dividend-paying companies — often called 'quality' companies — rather than simply the largest by market cap. The result is an index that may overlap significantly with the NGX 30 but also includes some companies that would not qualify by pure size, and may weight them differently. The '40' in the name refers to the 40 equities represented in this pension-aligned basket, versus the 30 in the NGX 30 Index.

SIAMLETF40 is managed by Stanbic IBTC Asset Management Limited — the same manager as STANBICETF30 — making this one of two Stanbic IBTC ETFs on the NGX. While STANBICETF30 tracks a pure market-cap ranking (the NGX 30), SIAMLETF40 tracks a pension-influenced selection and weighting (the NGX Pension 40). An investor choosing between them is essentially choosing between a market-cap passive approach and a pension-institution-aligned approach to Nigerian large-cap equity exposure. Neither is inherently superior — but understanding the methodology difference is important before making the choice.

The practical implications for investors are: broader diversification (40 holdings vs 30), a different weighting methodology that reflects PFA preferences rather than pure market cap, and exposure to 10 additional companies not in the NGX 30 at any given time. The fund also embeds a form of institutional quality filter, since the companies held must meet the ongoing investment criteria of Nigeria's regulated pension sector. As PFA allocation preferences evolve, the index composition will evolve with them.
