What Are the Key Differences in Execution Strategy between Public Equities and Private Market Assets?

Concept

The operational framework for asset execution is fundamentally bifurcated, dictated by the intrinsic structure of the market itself. Public equities and private market assets represent two distinct paradigms of capital formation and transfer, and their execution strategies are a direct consequence of their respective architectures. To view the challenge of execution as a uniform problem across both domains is to misdiagnose the core mechanics at play.

The system for transacting in public securities is a highly-engineered, continuous, and transparent mechanism designed for speed and volume. Conversely, the system for private assets is a fragmented, event-driven, and opaque network built on relationships, protracted negotiations, and specialized legal frameworks.

An allocation to public equities grants access to a centralized nervous system of liquidity. Here, the execution challenge is one of precision and stealth within a sea of continuous data. The price discovery process is dynamic and observable, unfolding in real-time through the interplay of millions of participants interacting with a central limit order book. The primary operational question is how to transact a large position without perturbing the very market that provides its liquidity.

The system’s transparency is its greatest strength and its primary vulnerability from an execution standpoint. Every action creates a data point, and the aggregation of these data points informs the behavior of all other participants. Therefore, the execution strategy becomes a sophisticated game of minimizing information leakage while navigating a complex topography of lit, dark, and semi-lit trading venues.

The core distinction lies in the market’s structure a continuous, transparent system for public equities versus a fragmented, opaque network for private assets.

In stark contrast, private market assets exist within a decentralized and fundamentally illiquid structure. There is no central order book, no continuous price feed, and no anonymous counterparty. Execution is not a matter of placing an order; it is a project of sourcing, negotiating, and closing a bespoke transaction. Price discovery is a deliberate, often arduous process, derived from extensive due diligence, bilateral negotiation, and periodic, model-based valuations rather than constant market interaction.

The key operational challenge shifts from minimizing market impact to overcoming information asymmetry and navigating a complex web of intermediaries, legal constraints, and principal-to-principal relationships. The system is defined by its opacity and the high friction associated with each transaction. Here, the execution strategy is one of network cultivation, due diligence mastery, and structural navigation.

Understanding this fundamental architectural divergence is the prerequisite for designing effective execution protocols. The tools, timelines, risk parameters, and even the definition of “best execution” are completely different. For public equities, the system provides liquidity, and the strategy is to optimize access to it.

For private assets, the strategy must first create the conditions for a transaction to even be possible, a process where liquidity is the outcome of a successful strategy, not a pre-existing condition of the market. This distinction shapes every subsequent decision, from technology architecture to the skill sets required of the execution team.

Strategy

Developing an execution strategy requires a deep appreciation for the underlying market microstructure of each asset class. The strategic objectives for public and private assets are derived from their contrasting environments of liquidity, information flow, and transaction finality. The resulting frameworks are necessarily distinct, one focusing on algorithmic precision and the other on negotiated access.

Public Equity Execution a Strategy of Algorithmic Optimization

The strategic imperative in public equity execution is the management of information leakage and the minimization of market impact. Given the continuous nature of the market and the high degree of transparency, a large order executed carelessly will inevitably move the price adversely, creating implementation shortfall. The strategy, therefore, is to dissect a large parent order into a multitude of smaller child orders and distribute them across time, venues, and price levels in a way that emulates the natural flow of the market.

This approach is inherently quantitative and technology-driven. The core components of the strategy include:

• Algorithmic Selection ▴ The choice of execution algorithm is the primary strategic decision. This is determined by the order’s characteristics (size relative to average daily volume), the security’s volatility profile, and the portfolio manager’s urgency. A passive strategy might use a Time-Weighted Average Price (TWAP) or Volume-Weighted Average Price (VWAP) algorithm to participate with the market over a set period. A more aggressive approach, driven by a strong short-term alpha signal, might deploy an implementation shortfall algorithm designed to front-load execution while balancing impact cost.
• Venue Analysis ▴ The modern public market is a fragmented landscape of national exchanges, alternative trading systems (ATS), and dark pools. A sophisticated strategy involves smart order routing (SOR) technology that dynamically seeks liquidity across these venues. The strategy dictates the routing logic, prioritizing certain venues for their liquidity characteristics or fee structures, while potentially avoiding others known for high concentrations of predatory high-frequency trading activity.
• Transaction Cost Analysis (TCA) ▴ TCA is not merely a post-trade report; it is a critical input into the strategic feedback loop. By analyzing execution performance against benchmarks (e.g. arrival price, VWAP), traders can refine their algorithmic choices, venue preferences, and timing decisions. The strategy is to continuously learn from execution data to improve future performance, creating a cycle of optimization.

Public equity strategy centers on algorithmic precision to minimize market impact across a fragmented, transparent landscape.

The table below outlines a simplified decision matrix for algorithmic selection based on order characteristics and market conditions, a typical component of an institutional execution policy.

Private Market Execution a Strategy of Negotiated Access

Execution strategy in private markets is fundamentally a qualitative and network-driven endeavor. The primary objective is to locate a willing counterparty and agree on a price for an asset that does not have a readily available market value. The strategy is proactive and long-term, focused on building the infrastructure necessary to transact when the opportunity arises.

The core components of this strategy are:

• Network and Intermediary Management ▴ The lifeblood of private market execution is the network of general partners (GPs), limited partners (LPs), investment bankers, and specialized secondary advisors. The strategy involves cultivating deep relationships with these participants to gain access to deal flow and market intelligence. Selecting the right intermediary for a specific transaction is a key strategic decision, as their network and expertise can be the difference between a successful closing and a failed process.
• Due Diligence as a Pricing Tool ▴ Since price is not discovered through a continuous auction, it must be constructed through rigorous due diligence. The strategy involves a multi-faceted analysis of the target company’s financials, operations, management, and competitive landscape. This internal valuation work forms the basis of the initial offer and the subsequent negotiation. The depth and quality of the due diligence directly influence negotiating leverage.
• Structuring and Negotiation ▴ Private market transactions are complex and highly structured. The strategy extends beyond agreeing on a headline price to negotiating a wide range of terms, including representations and warranties, indemnification, and potential earn-outs. The legal and tax implications of the transaction structure are paramount. The negotiation process itself is a strategic exercise in information control, managing timelines, and understanding the counterparty’s motivations.

How Does Liquidity Influence Strategy?

The fundamental difference in liquidity dictates the temporal aspect of the strategy. Public equity strategies operate on a microsecond-to-hours timeframe, optimizing trades within a continuous flow. Private market strategies operate on a weeks-to-months timeframe, involving a sequential process of sourcing, diligence, negotiation, and closing. The former is a high-frequency optimization problem, the latter a long-duration project management exercise.

Execution

The execution phase translates strategy into action, and the operational mechanics for public and private assets could not be more divergent. Public equity execution is a technology-centric workflow managed through sophisticated order management systems. Private market execution is a human-capital-intensive process managed through legal documents and personal networks.

The Operational Playbook for Public Equities

The execution of a large institutional equity order is a systematic, multi-stage process governed by pre-defined protocols and managed through an Execution Management System (EMS). The process is designed for efficiency, control, and the measurable reduction of implicit trading costs.

1. Order Generation and Pre-Trade Analysis ▴ The process begins when a Portfolio Manager sends a large “parent” order to the trading desk. The first step is a pre-trade analysis, where the trader uses TCA tools to estimate the potential market impact, expected cost, and risk of the trade based on its size, the stock’s historical volatility, and current market conditions.
2. Algorithm and Parameter Selection ▴ Based on the pre-trade analysis and the PM’s instructions regarding urgency, the trader selects an appropriate execution algorithm (e.g. VWAP, IS, POV) and sets its parameters. This includes defining the start and end times for the execution, setting price limits, and specifying the level of aggression.
3. Execution and Real-Time Monitoring ▴ The EMS routes “child” orders to various market centers according to the algorithm’s logic. The trader’s role shifts to monitoring the execution in real-time. They watch for adverse price movements, unexpected changes in volume, or news that might affect the stock. The trader can intervene at any point, adjusting the algorithm’s parameters, pausing the execution, or switching to a different strategy if market conditions change dramatically.
4. Post-Trade Analysis and Reporting ▴ Once the parent order is complete, a detailed TCA report is generated. This report compares the execution price against various benchmarks (Arrival, VWAP, Interval VWAP) and breaks down the costs, including commissions and market impact. This data is used to evaluate the effectiveness of the execution strategy and to refine future trading protocols.

The Operational Playbook for Private Markets

Executing a private market transaction is a bespoke, milestone-driven process that relies heavily on specialized expertise and negotiation. It is less about algorithmic precision and more about managing a complex, multi-party project over an extended period.

1. Sourcing and Initial Vetting ▴ The process begins with identifying a potential investment or locating a buyer for an existing position. This is typically achieved through a network of investment bankers, secondary advisors, or direct outreach. Initial vetting involves signing a Non-Disclosure Agreement (NDA) and reviewing a Confidential Information Memorandum (CIM) to determine if there is a strategic fit.
2. Indication of Interest (IOI) and Due Diligence ▴ If the opportunity is attractive, the investor submits a non-binding Indication of Interest, which outlines a potential valuation range. If the IOI is accepted, a period of intensive due diligence begins. This involves creating a data room, conducting management meetings, and engaging legal and financial advisors to scrutinize every aspect of the business.
3. Letter of Intent (LOI) and Definitive Agreements ▴ Following successful due diligence, a more formal Letter of Intent is negotiated. The LOI specifies the price, structure, and key terms of the proposed transaction. This leads to the drafting of definitive legal agreements, such as a Share Purchase Agreement (SPA), which is a lengthy and intensive process involving legal counsel from all parties.
4. Closing and Funding ▴ The final stage involves finalizing all legal documentation, obtaining any necessary regulatory or shareholder approvals, and transferring the funds. The transaction is considered complete only when the funds have cleared and the ownership transfer is legally recorded.

What Are the Primary Execution Costs?

The cost structures for executing in these two markets are fundamentally different. Public market costs are implicit and measured in basis points, while private market costs are explicit and can be a significant percentage of the transaction value.

Execution in public markets is a high-frequency, data-driven process, while private market execution is a long-duration, document-intensive project.

The table below provides a comparative breakdown of typical transaction costs.

This stark contrast in cost structure underscores the different nature of the execution challenge. In public equities, the focus is on the micro-management of implicit costs through technology. In private markets, the focus is on the macro-management of large, explicit, project-based costs through negotiation and expert advisory.

Reflection

The examination of these two execution paradigms reveals a foundational truth about capital markets ▴ the architecture of the market dictates the nature of the game. An institution’s operational framework must be purpose-built to navigate the specific environment in which it chooses to deploy capital. A superior execution capability in public equities, characterized by low-latency technology and quantitative sophistication, provides little advantage in the relationship-driven world of private assets. Similarly, a world-class M&A team is ill-equipped to manage the microsecond complexities of algorithmic trading.

Where Are the Gaps in Your Own Operational Framework?

The critical question for any capital allocator is whether their execution infrastructure is truly aligned with their investment strategy. Does the technological stack for public market access provide the necessary granularity of control and data for continuous improvement? Does the human capital infrastructure for private markets possess the network reach and structuring expertise required to source and close proprietary deals?

Acknowledging the profound differences between these domains is the first step. Building a truly resilient and effective operational system requires a deliberate and distinct approach to mastering each one.
