ACI Growth Fund vs Booster Wealth Growth Fund
Both are Diversified funds available to NZ retail investors. Numbers below are sourced from the FMA Disclose register via Sorted Smart Investor and reflect the latest published quarterly fund updates.
Why these two differ
The most material structural difference between these two funds is their annual fund charge: ACI Growth Fund discloses 1.61%, while Booster Wealth Growth Fund discloses 0.91% — a 70-basis-point gap that compounds meaningfully over time on any invested balance. Both funds sit in the Diversified category with an identical risk indicator of 4 (on a 1–7 scale) and nearly identical growth asset allocations of 78.34% and 78.48% respectively, making the fee differential particularly prominent given the otherwise similar risk profile. Neither fund discloses a five-year return figure in this snapshot, so no historical performance comparison is available here.
The two funds diverge considerably in portfolio construction. ACI Growth Fund's largest exposures are to pooled vehicles — Dimensional Emerging Markets Sustainability Trust (13.3%) and Smartshares NZ Core Equity Trust (12.32%) — giving it a fund-of-funds character with a notable emerging markets tilt. Booster Wealth Growth Fund's disclosed top holdings are predominantly individual securities, including Fisher & Paykel Healthcare (3.02%), NVIDIA Corp (2.34%), and Auckland International Airport (1.87%), with no single position exceeding 3.63%, suggesting broader direct-equity diversification at the holding level. Apple Inc appears in both funds' top-five lists. Fund sizes are comparable — ACI at approximately NZD 7.66 million and Booster at approximately NZD 7.23 million.
