The search for a stable, long-term wealth creation partner has never been more important. With markets constantly shifting gears and investors demanding clarity over noise, performance alone doesn’t cut it anymore—what matters is consistency, discipline, and the ability to protect capital when the tide turns. Two PMS players often find themselves compared on this front: Marcellus Investment Managers and Buoyant Capital. Both have earned investor trust, both follow differentiated philosophies, and both promise stability—but the way they deliver it is remarkably different. This deep dive explores how these strategies stack up when stability becomes the headline priority for investors evaluating the right fit through platforms like AltPort Funds.

Understanding the Philosophy Behind Each PMS

Before diving into performance behavior and risk characteristics, it helps to understand the DNA of both strategies. A PMS is not just about what it buys; it’s about the thought process behind why it buys, how long it holds, and what rules guide the portfolio through good and bad cycles.

Marcellus Investment Managers: Stability Through Quality and Clean Accounting

Marcellus Investment Managers was built on one central idea—Indian wealth creation becomes simpler and more accessible when capital flows to companies with robust competitive advantages, ethical governance, and consistent capital allocation. The team’s 15-year history of working together has shaped a philosophy grounded in forensic accounting, economic moats, and long-term compounding.

Stability for Marcellus comes from its “quality-first” selection process. By filtering more than 450 mid-sized companies through rigorous clean accounting checks and governance screens inspired by forensic research frameworks, Marcellus eliminates businesses that carry hidden risks. Only those that demonstrate predictable earnings, sustainable return ratios, and disciplined reinvestment models make it to the Rising Giants portfolio.

This focus translates into lower volatility, fewer surprises, and a compounding model that behaves very differently from the fast-paced churn seen across the PMS industry. With 15–20 stocks held over many years, the strategy seeks to capture long-duration earnings growth without frequent rotation.

Buoyant Capital: Stability Through Flexibility and Active Risk Management

Buoyant Capital approaches stability from another direction—portfolio adaptability. The firm combines top-down views with bottom-up research to dynamically shift allocations as economic cycles change. Their objective is simple: deliver better returns relative to the risk taken, regardless of market phase.

Where Marcellus stays planted in its quality universe, Buoyant moves fluidly across large-cap stability, mid-cap growth, cyclical opportunities, turnaround candidates, and cash. The portfolio reflects constant judgment calls on what sectors deserve higher exposure and which need trimming.

The strategy’s sector tilts showcase a willingness to capture upside in areas gaining momentum—such as recent additions in Info Tech, Insurance, and Banking—while reducing exposure to segments like Misc, Healthcare, and Media when conditions demand caution. With core holdings accounting for over half the portfolio and satellite positions adding tactical edge, Buoyant delivers stability through active risk-balancing rather than long-term concentration.

Portfolio Construction: Concentration vs Flexibility

When investors ask for stability, what they often mean is predictability. That predictability can be created either through high conviction or through diversification. Marcellus and Buoyant sit at different ends of this spectrum.

Marcellus: High Conviction, Low Turnover

The Rising Giants portfolio invests only in businesses that pass three robust filters: clean accounting, disciplined capital allocation, and durable competitive moats. From the broader universe, only 15–20 companies survive the entire screening process. This means each company carries real weight in the portfolio and remains there for several years unless fundamentals drastically change.

This style benefits investors who prefer low volatility, elegant simplicity, and long-term clarity. There is no clutter, no frequent buying and selling, and no tactical shifts. The result often looks like a smooth trajectory over long horizons.

Buoyant: Dynamic Allocation, Tactical Adjustments

Buoyant uses a more diversified set of levers. The portfolio spreads across large-, mid-, and small-cap opportunities with the flexibility to shift weights quickly based on economic signals. The blend of core positions (57%) and satellite positions (43%) ensures that while the portfolio maintains a structural backbone, it can tactically participate in emerging opportunities.

This dynamism is evident from the month-on-month and quarter-on-quarter shifts—where sectors like Info Tech and Chemicals see rising weights while areas like Media or NBFC see reductions. For investors who value adaptability, this flexibility can be a major source of stability during changing market environments.

Risk Management: Where Stability Truly Shows Up

Risk management is where the philosophies of both funds become most visible.

Marcellus: Risk Reduction Through Governance and Moats

Marcellus minimizes risk before a stock ever enters the portfolio. The forensic accounting framework eliminates businesses with aggressive accounting, governance issues, or weak cash flows. Companies with sustained ROCE, consistent reinvestment ability, and dominant market positions demonstrate resilience during downturns.

The clean-accounting approach is especially valuable in an Indian market where headline numbers often hide deeper inconsistencies. The final portfolio tends to behave like a low-volatility compounding machine, offering stability through predictability of fundamentals.

Buoyant: Risk Reduction Through Diversification and Beta Control

Buoyant’s risk controls show up in its metrics. With a beta of 0.9 across horizons and steadily improving Sharpe and Sortino ratios (Sortino rising to 4.0 over three years), the strategy demonstrates that active shifts can, in fact, deliver better risk-adjusted returns. The portfolio maintains cash allocations when necessary (currently around 12.5%), which helps buffer volatility.

Sector balancing ensures that no single theme derails performance. This approach offers stability not through the nature of holdings but through the agility with which risk exposures are managed.

Performance Behavior Across Market Cycles

Stability is not just about numbers—it’s about how a strategy behaves across cycles. Marcellus and Buoyant differ significantly here.

Marcellus: Consistency in Trending Markets

Marcellus tends to shine during steady bull markets where earnings compounding becomes the driving force behind equity returns. Since its Rising Giants portfolio is built on companies with structural growth, low leverage, and strong moats, performance remains consistent without dramatic fluctuations. In volatile markets, the portfolio may not move sharply upward, but it avoids steep drawdowns due to the inherent quality of its holdings.

Buoyant: Responsiveness in Choppy Markets

Buoyant demonstrates resilience in choppier cycles due to its flexible allocation model. When certain sectors face headwinds, the manager shifts exposure. When growth pockets emerge, the portfolio pivots to capitalize. This responsiveness becomes a strength during transitional or uncertain market phases. Investors preferring an agile model often gravitate to Buoyant for this reason.

Which PMS Offers More Stability?

The answer depends on what “stability” means for an investor’s personality and goals.

When Marcellus Provides More Stability

Marcellus may be the better option when stability means:

Predictable long-term compounding
Limited portfolio churn
Exposure to companies with clean books and proven governance
Lower volatility and fewer surprises
Staying anchored to structural growth stories

Investors who prefer clarity, quality, and long-term ownership often find Marcellus deeply reassuring.

When Buoyant Provides More Stability

Buoyant may be the preferred choice when stability means:

A portfolio that adapts as markets change
Balancing cyclical, turnaround, and value opportunities
Lower reliance on a concentrated set of companies
Tactical sector rotation to manage volatility
Data-driven decisions supported by continuous top-down and bottom-up research

Investors who appreciate agility and risk-adjusted decision-making find Buoyant better aligned with their needs.

Final Word: The Right Fit Depends on How You View Stability

Both PMS strategies offer stability, but through different philosophies. Marcellus Investment Managers delivers stability through discipline, clean accounting, and long-duration compounding. Buoyant Capital delivers stability through adaptability, diversification, and dynamic risk management. Neither is inherently better—each simply works for a different type of investor.

At AltPort Funds, the real advantage lies in helping investors match their temperament, goals, and risk appetite with the right PMS strategy. When stability becomes the benchmark, the conversation shifts from chasing returns to choosing the investment style that stays steady when it matters most.
