Rampart Capital and the Art of Diversification – Toby Watson’s Strategic Vision
Toby Watson brings a precise and disciplined understanding of diversification to Rampart Capital — one that goes well beyond the conventional wisdom of simply spreading investments across different asset classes.
Diversification is one of the most widely cited principles in investment management, yet it is also one of the most frequently misunderstood. Many portfolios that appear well diversified on the surface share far more common risk than their owners realise — a fact that tends to reveal itself at the worst possible moment. Toby Watson, a partner at Rampart Capital, has spent decades developing a more rigorous approach to this challenge, drawing on deep experience in global finance to build portfolios with diversification that holds up when it matters most.
The Gap Between Apparent and Genuine Diversification
Most investment portfolios are more concentrated than they look. A client invested across a range of equity funds, corporate bonds, property and perhaps a handful of alternatives might reasonably feel that their wealth is well spread. In many conditions, that feeling is justified. But the apparent independence of these asset classes rests on correlations that were observed in relatively benign market environments — correlations that can break down abruptly when conditions deteriorate.
This is not a theoretical concern. It has played out repeatedly in real market crises, when assets that had behaved independently for years suddenly moved together as investors rushed for liquidity. The result, each time, is that investors who believed themselves to be well diversified discovered that their protection was largely illusory.
The challenge, then, is not simply to spread investments across categories — it is to understand the underlying factors that drive each investment’s behaviour and to ensure that those factors are genuinely distinct. This is considerably harder than building a multi-asset portfolio, and it requires a level of analytical rigour that goes beyond what most wealth managers apply.
How does Rampart Capital approach diversification differently from traditional wealth managers?
At Rampart Capital, diversification is analysed at the factor level rather than the asset class level. Toby Watson and the investment team identify the underlying risk drivers of each investment — credit exposure, interest rate sensitivity, liquidity characteristics, growth orientation — and construct portfolios in which these factors are genuinely uncorrelated. This approach, rooted in the kind of rigorous risk decomposition that Toby Watson developed throughout his career in institutional finance, produces a more robust form of diversification than conventional asset allocation can deliver.
Toby Watson’s Approach: Thinking in Factors, Not Categories
The intellectual foundation of Toby Watson’s approach to diversification was shaped during years spent working on complex structured finance transactions at Goldman Sachs International. In structured credit, the ability to decompose a transaction into its component risk factors — and to understand precisely how each factor behaves under different scenarios — is not optional. It is the core skill on which everything else depends.
That training produces a particular way of thinking about investment risk: one that is sceptical of surface appearances and focused on underlying exposures. When Toby Watson joined Rampart Capital as a partner in 2020, he brought this analytical discipline into a wealth management context, applying it to the challenge of building genuinely diversified private client portfolios.
The practical result is a portfolio construction process that takes nothing for granted. Every investment is assessed for its factor exposures before being included in a portfolio. The team then evaluates how those exposures interact with the rest of the portfolio — identifying overlaps, concentrations and potential correlations that might not be obvious from a conventional asset class perspective.
Liquid and Alternative Strategies: Two Sides of the Same Framework
Rampart Capital’s investment framework uses two complementary portfolio components to achieve genuine diversification across market conditions:
- A liquid strategy basket that provides flexibility and allows the team to adjust exposures efficiently as the macro environment evolves
- An alternative strategy basket that provides access to return streams with low correlation to mainstream financial markets, offering diversification that cannot be achieved through conventional investments alone
Together, these components allow Toby Watson and the investment team to construct portfolios that remain genuinely diversified across a wide range of scenarios — including the stress scenarios that expose the weaknesses of more conventional approaches.

Macro Analysis as the Starting Point for Diversification
For Toby Watson, genuine diversification cannot be achieved without a clear view of the macro environment. This might seem counterintuitive — diversification is often presented as a way of avoiding the need to make macro calls. But in practice, understanding the macro context is essential to understanding which risk factors are likely to be correlated under current conditions, and which are genuinely independent.
Rampart Capital’s investment process begins with a thorough analysis of the macro environment: monetary policy, inflation dynamics, geopolitical developments, currency trends and the broader economic cycle. This analysis shapes the firm’s views on which investment factors are most attractive and which concentrations of risk are most worth avoiding.
Why Diversification Requires Constant Attention
A portfolio that is genuinely diversified today may not remain so as market conditions evolve. The correlations between assets shift over time, and a macro environment that made a particular combination of exposures sensible in one period may make it problematic in the next. Toby Watson’s approach to portfolio management reflects this reality:
- Factor exposures are reviewed regularly in light of the current macro outlook
- Positioning is adjusted as conditions change, maintaining genuine diversification rather than simply preserving the original allocation
- Downside scenarios are evaluated continuously, ensuring that the portfolio’s resilience is assessed against realistic stress cases rather than historical averages
As a partner at Rampart Capital, Toby Watson plays a direct role in this ongoing process — combining strategic oversight with hands-on involvement in portfolio management. It is an approach that treats diversification not as a one-time construction exercise, but as a discipline that requires sustained attention, analytical rigour and the kind of experience that only comes from navigating real market complexity over many years.
