Historically, private equity was pursued for its potential outperformance (alpha). Today, with shrinking public markets, its main value is providing diversification and access to a growing universe of private companies that are no longer available on public exchanges. This makes it a core portfolio completion tool.

During due diligence, it's crucial to look beyond returns. Top allocators analyze a manager's decision-making process, not just the outcome. They penalize managers who were “right for the wrong reasons” (luck) and give credit to those who were “wrong for the right reasons” (good process, bad luck).

A common mistake for emerging managers is pitching LPs solely on the potential for huge returns. Institutional LPs are often more concerned with how a fund's specific strategy, size, and focus align with their overall portfolio construction. Demonstrating a clear, disciplined strategy is more compelling than promising an 8x return.

In a world of highly skilled money managers, absolute skill becomes table stakes and luck plays a larger role in outcomes. According to Michael Mauboussin's "paradox of skill," an allocator's job is to identify managers whose *relative* skill—a specific, durable edge—still dominates results.

Many LPs focus solely on backing the 'best people.' However, a manager's chosen strategy and market (the 'neighborhood') is a more critical determinant of success. A brilliant manager playing a difficult game may underperform a good manager in a structurally advantaged area.

The era of generating returns through leverage and multiple expansion is over. Future success in PE will come from driving revenue growth, entering at lower multiples, and adding operational expertise, particularly in the fragmented middle market where these opportunities are more prevalent.

A fund manager's fiduciary duty incentivizes them to trade potentially higher, more volatile returns for guaranteed, quicker multiples (e.g., a 3.5x over a 7x). Unlike a personal investor who can accept high dispersion (big winners, total losses), a GP must prioritize returning capital to LPs like pensions and endowments.

The majority of venture capital funds fail to return capital, with a 60% loss-making base rate. This highlights that VC is a power-law-driven asset class. The key to success is not picking consistently good funds, but ensuring access to the tiny fraction of funds that generate extraordinary, outlier returns.

When a private equity investment thesis is primarily built around a single person (e.g., a star CEO), it's a sign of weak conviction in the underlying business. If that person fails or leaves, the entire rationale for the investment collapses, revealing a lack of fundamental belief in the company's industry or competitive position.
