Portable Alpha and Alpha Extension Explained

In this episode of CIO Perspectives, Sid Ahl and Erika Pagel, Co-CIOs for Private Clients, Endowments and Foundations at Brown Advisory, sit down with Jordan Wruble, partner and head of Investment Solutions at the firm. Jordan brings three decades of experience across investment banking, private equity, hedge funds and manager research, offering a unique perspective on how the art and science of investing has evolved—and what it takes to identify exceptional managers in today’s competitive landscape.

The conversation explores timeless principles of fundamental investing, the rise of data-driven strategies and the five sources of “edge” that top managers leverage to outperform. Jordan shares how Brown Advisory evaluates managers beyond performance—focusing on process, discipline and alignment—and why passion and curiosity remain the ultimate differentiators.

Macro themes also take center stage: the Fed’s “hawkish cuts,” AI-driven capital expenditure, market concentration and the bifurcation of the U.S. economy. Jordan discusses how these dynamics are shaping opportunities across global markets and why patience and selectivity are critical in an environment dominated by mega-cap tech and narrative-driven trades.

The episode closes with insights on portfolio construction, risk management and the role of AI as a research accelerator—not a replacement for judgment. Sid and Erika reflect on Jordan’s thoughtful approach and the importance of staying grounded in fundamentals amid rapid change.

Hedge Funds involve complex tax and legal structures. Investment in any particular Fund or hedge funds, generally, is only suitable for sophisticated investors for whom such an investment does not constitute a complete investment program and who fully understand and are willing to assume the risks involved in such investment.

Private investments are characterized by a high degree of risk, volatility and illiquidity due, among other things, to the nature of the investments. A prospective investor should thoroughly review the Offering Materials pertaining to any investment and carefully consider whether such an investment is suitable to the investor’s financial situation and goals. Investors should have the financial ability and willingness to accept the risks and lack of liquidity that are characteristic of these types of investments. There can be no assurance that any investment objectives will be achieved, or that investors will receive a return of their capital. Accordingly, investors should only invest in private credit investments if such investors are able to withstand a total loss of their investment.
