Investment management has become increasingly complex. Markets move faster, information flows constantly, regulation continues to evolve, and artificial intelligence is beginning to reshape how decisions are made.
Against this backdrop, one of the most significant developments in South Africa’s investment landscape has been the rapid rise of discretionary fund managers (DFMs). In a recent discussion with Leigh Kohler, Head of DFM at INN8 Invest, and Joao Frasco, Chief Investment Officer, we unpacked not only the growing role of DFMs, but also broader themes around risk, investment philosophy, complexity and AI.
The conversation started with a concept Kohler introduced during an investment summit in Cape Town, “the power of three.” “The number three is just an interesting number generally,” Kohler explained. “What I tried to do in the presentation was build up the relevance of the number three in different contexts.” Eventually, that framework led to market behaviour itself. A market shock, he explained, is generally defined as a 3% daily move in markets, while a “black swan” event is often seen as a 5% negative move.
Using the S&P as a proxy, Kohler noted that since 2020 there had already been 46 market shock events, 16 of which qualified as black swan events. “The point,” he said, “is that there’s a lot of uncertainty in markets. You cannot approach investing like throwing darts at a dartboard.” That uncertainty, he argued, is exactly why advisors increasingly rely on DFMs to help navigate increasingly volatile and complex investment environments.
Kohler described INN8 Invest’s philosophy through what he called the “three Ps”, pedigree, power and partnerships. Pedigree refers to investment experience and institutional depth. “We’ve been managing money as a DFM and multi-manager for 25 years,” he explained. “We’ve seen multiple market cycles and many different events through that period.”
Importantly, he stressed that longevity alone is not enough. “It’s not just that we’ve been there for 25 years, we’ve been there outperforming over that time.” That experience is reinforced by scale. While many DFMs operate with relatively small teams, Kohler pointed out that INN8 Invest has roughly twenty investment professionals spread across Johannesburg, Cape Town, Jersey and London, combining global and local expertise under one structure.
The second “P”, power, relates to institutional scale and the ability to negotiate better investment outcomes. “We negotiate institutional fee classes and pass those benefits on to clients,” Kohler explained. He also highlighted how perceptions around independence have evolved since Covid. “Before 2020, being completely independent was fashionable,” he said. “But after Covid, clients increasingly value the comfort of knowing their DFM is backed by a larger organisation with balance sheet strength and long-term sustainability.”
The final “P”, partnerships, may be the most important. Kohler emphasised that DFMs sit between asset managers and financial advisors, helping both parties work collectively for the benefit of end investors. “What advisors are thinking matters,” he said. “Not every practice needs a cookie-cutter solution.” That collaborative model reflects a broader transformation that has taken place within South Africa’s retail investment market over the past two decades.
According to Kohler, roughly 25% of retail assets on LISP platforms now sit within DFM portfolios, a dramatic increase from the estimated R40 billion managed by DFMs many years ago to roughly R750 billion today. “DFMs have institutionalised the retail investment market,” he explained. Where asset allocation decisions were once heavily influenced by relationships, reputation or marketing, DFMs introduced greater discipline, due diligence and governance into the allocation process.
The growing popularity of DFMs also reflects another reality, advisors increasingly recognise that they cannot do everything themselves. Joao Frasco shared an anecdote from the summit where he overheard two advisors discussing exactly this point. “One advisor said, ‘I don’t get paid to select funds. I don’t have the time to do that. My role is advising clients on their financial needs.’”
That observation, Frasco said, perfectly captures the value proposition of a DFM. With approximately 1 900 local funds available, and tens of thousands globally, advisors simply do not have the time to perform the level of due diligence required to evaluate managers properly. “That’s where the DFM steps in,” Kohler explained. “We provide investment alpha, practice alpha and advice alpha.”
Investment alpha comes from portfolio construction and manager selection. Practice alpha comes from operational efficiencies and scalable portfolio management. Advice alpha allows advisors to focus more deeply on behavioural coaching and client relationships.
Frasco then introduced a fascinating philosophical dimension to the discussion.
Using the analogy of bricks forming a wall, he rejected the idea that investment success comes from a single “silver bullet” or rigid investment style. “A portfolio is not a single brick,” he explained. “It’s many bricks working together.” Those bricks include manager research, portfolio construction, strategic asset allocation, operational due diligence, data systems and people, all contributing collectively to investment outcomes.
That thinking ties closely into what Frasco called the “philosophy of emergence.” Borrowed from biology and systems theory, emergence describes how complex outcomes arise from relatively simple interactions. He used the example of flocks of birds moving in coordinated patterns. “There’s no single bird directing the movement,” he explained. “Complexity emerges from a few simple rules.”
Frasco believes capital markets function similarly. Markets are shaped by millions of interactions between investors, companies, governments and institutions, producing outcomes that are often impossible to predict purely from analysing individual components. That complexity also influences how investment teams themselves are built.
“The single most important factor is people,” Frasco said. He argued strongly against the old “star portfolio manager” model, favouring instead diverse teams with different perspectives, experiences and analytical lenses. “In investments, you actually want disagreement,” he explained. “You want people seeing the world differently.”
That diversity of thought becomes increasingly important in an environment where AI is beginning to transform investment analysis itself. Frasco described AI as “the most consequential technology ever. We’ve essentially invented intelligence,” he said.
He explained how AI is already helping with coding, portfolio analytics, manager analysis and data interpretation within investment businesses. Importantly, he does not see AI replacing human expertise but rather amplifying it. “The DFM gives you structure,” he said. “AI gives you scale.”
For advisors, however, the core lesson remains remarkably simple. As I noted toward the end of our discussion, even after years of training financial advisors myself, I still use a financial advisor personally. Why?
Because in an increasingly specialised and complex world, value comes from knowing where expertise sits and building the right partnerships around it.
