The Zimbabwe Stock Exchange (ZSE), one of Africa’s oldest stock exchanges, is attracting renewed analytical attention following the publication of its first quarter index composition. The data reveals a growing concentration of value among a small number of large firms, a development that local equities research firm Equity Axis argues poses structural risks to market integrity.
According to the research note released on 21 January, three major counters including telecommunications group Econet Wireless Zimbabwe and beverages giant Delta Corporation now account for over seventy per cent of the ZSE’s Top 10 Index. While the Top 15 Index offers slightly broader exposure, its composition remains similarly skewed towards these dominant players.
Equity Axis has characterised this trend as symptomatic of a “structurally contracting” market. The think tank argues that index stability is no longer being driven by organic market expansion or new listings, but by internal reweighting within an increasingly narrow pool of companies. Such a dynamic, they caution, may undermine the reliability of indices as representative indicators of market health.
The ZSE, founded in 1894 and currently comprising approximately 63 listed entities, has been trading in the Zimbabwe Gold (ZWG) currency. However, recent and upcoming departures of major counters may further intensify the concentration dynamic. Econet Wireless Zimbabwe, a major telecommunications and fintech player, has announced plans to delist, citing misalignment between its true valuation and market perception. It plans to spin off its infrastructure segment and list it on the Victoria Falls Stock Exchange, a dollar-based platform under the ZSE umbrella.
The earlier exit of National Tyre Services in December underscores a broader trend of movement within Zimbabwe’s capital ecosystem. Equity Axis notes that such shifts may reduce overall liquidity, heighten index concentration, and shrink the diversity of sectors represented. Passive portfolios and index-tracking funds could face heightened rebalancing pressures, leading to volatility and distorted investor signals.
“The emerging structure of the ZSE indices increasingly reflects a few dominant companies, mostly in consumer, property, and banking sectors,” the research note concludes. “This undermines the role of indices as reliable proxies for broader economic or market trends.”
However, this perspective is not universally shared. Tariro Mandizvidza, a Harare-based financial analyst and portfolio strategist, cautions against overly pessimistic readings.
“While index concentration is a valid concern, it is also reflective of underlying economic realities where only a handful of firms have achieved significant scale and resilience,” she said in an interview. “Rather than viewing this solely as a structural failure, we should also recognise the adaptability of these firms and consider how policy reforms and exchange innovations might encourage the growth of second-tier listings.”
Mandizvidza also highlighted the role of the Victoria Falls Stock Exchange (VFEX) in attracting listings that require more stable and investor-friendly currency environments. “The creation of the VFEX offers a dual-track approach to capital raising. It’s not just about who leaves the ZSE, but where they go and how their reallocation contributes to the evolution of the market ecosystem,” she added.
From a pan African vantage point, Zimbabwe’s experience echoes broader regional challenges, where the dominance of a few mega-cap stocks is common across many exchanges. The limited depth of African capital markets often results in outsized influence of major firms, underscoring the need for more deliberate market development strategies.
Yet, this moment can also be reframed as an opportunity. The evolving market structure presents a case for rethinking index construction, broadening listing incentives, and deepening investor education around portfolio diversification beyond headline indices. It also encourages African capital markets to develop metrics and tools rooted in local realities rather than inherited frameworks.
In this context, the path forward for Zimbabwe’s financial markets may depend less on lamenting departures and more on ensuring that exits, reentries, and listings take place within a coherent, strategically aligned market vision — one that places African resilience and innovation at its centre.
