MerQube, a U.S.-based provider of rules‑based investment technology, has teamed with Oribi Capital Partners and Prescient Management Company to launch an exchange‑traded fund that tracks the newly created South Africa Top 30 Index. The product, named the Oribi South Africa Top 30 Prescient ETF, aims to give investors a more balanced exposure to equities listed on the Johannesburg Stock Exchange.
How the index is built
The index, officially titled the MerQube South Africa Top 30 Price Return Index (ZAR) (MQZA30P), selects the ten largest firms from each of three equity segments: Resources, Financials and Diversified. By assigning an equal 33.3 % weight to each sector, the benchmark reduces the concentration risk that often plagues traditional South African indices.
Eligibility requires companies to be common equities primarily listed on the JSE, domiciled in South Africa, and to have a free‑float factor of at least 10 %. Within each sector, constituents are ranked by free‑float market capitalisation, and the top ten are chosen. The index is calculated in three variants—price return, total return and net total return—to accommodate different investment mandates.
Rebalancing occurs annually. Data as of the end of February determine the new composition, and changes are applied on the third Friday of March. This schedule aligns with the typical corporate reporting calendar for many South African firms.

ETF structure and market impact
The ETF gives investors a listed vehicle that mirrors the index’s performance. Oribi and Prescient manage the fund, while MerQube acts as sponsor, administrator and calculation agent. The partnership handles methodology design, sector classification, rebalancing and daily index calculations.
According to Zack Bezuidenhoudt, head of sales for EMEA and APAC at MerQube, the index was created to address “concentration risk for investors” that stems from the dominance of a few mega‑cap companies in existing South African benchmarks. He added that the new structure “provides a transparent, rules‑based benchmark that spreads exposure across sectors without sacrificing scale or investability.”
By offering a sector‑balanced approach, the ETF may attract investors who have been wary of the skew toward resources‑heavy holdings in traditional indices. The equal weighting at both sector and constituent levels also means that performance is less likely to be driven by a single company’s fortunes.
One possible implication is that asset managers could see a shift in allocation patterns toward more diversified South African exposure. If the ETF gains traction, it might prompt other issuers to develop similar products, potentially broadening the market’s overall liquidity.

The launch marks MerQube’s continued expansion into emerging‑market index solutions. In addition to the South Africa Top 30, the firm plans to introduce benchmarks for markets such as South Korea and Taiwan, signaling a broader strategy to provide sector‑aware tools for a range of economies.
Investors interested in the ETF can track its performance through standard market data feeds, and the index’s methodology is publicly available for review. As the first of its kind in the South African space, the product offers a new avenue for diversified equity investment without the heavy tilt toward a handful of large‑cap names.
