SouthernSun Asset Management

Phillip Cook serves as President and Chief Investment Officer, overseeing all portfolio management. He leads the investment team in executing the firm's concentrated, fundamental value strategy. Founder Michael Cook remains involved as CEO, providing continuity rooted in the firm's 1989 founding principles.

SouthernSun employs a concentrated, long-only value-equity strategy focused on small- and mid-cap companies. The team builds portfolios of 20–35 names through rigorous bottom-up research, seeking businesses with strong balance sheets and durable moats trading below intrinsic value. The firm is benchmark-agnostic and maintains a low-turnover approach.

The firm was founded in Memphis by Michael Cook and has intentionally remained there to maintain distance from Wall Street consensus-thinking. This geographic isolation supports the firm's patient, independent research culture. For allocators, the location is viewed as reinforcing rather than limiting the strategy's contrarian bent.

SouthernSun is a privately held, founder-led firm with a defined family succession. Founder Michael Cook transitioned the CIO role to his son, Phillip Cook, creating a rare multi-generational governance structure. This arrangement aims to preserve investment philosophy continuity without the disruption of external executive turnover.

The firm invests directly in publicly traded equities through its separately managed accounts and proprietary mutual funds. It does not operate as a fund-of-funds or allocate to external private-market managers. The strategy is purely long-only, concentrated public equity.

SouthernSun's mandate centers on tangible, asset-intensive businesses in industrials, materials, financials, and consumer sectors. The firm has historically avoided speculative technology, pre-revenue biotech, and high-beta, concept-driven names that do not fit its disciplined valuation framework. The CIO has publicly articulated a preference for capital-cycle-exposed sectors where deep value can be analytically mined.

SouthernSun concentrates on small- and mid-capitalization companies, typically those with market values between $500 million and $10 billion at time of initial purchase. This market-cap band offers the inefficiencies and under-coverage the firm's 20-35 stock portfolio exploits. A smaller-cap tilt reflects the firm's view that sell-side neglect creates persistent mispricing.
