The family office playbook for concentrated stock: financing, hedging, and long-term stewardship

For many wealthy families, a large block of shares in one listed company is not just a portfolio holding. It is the main store of family wealth, often built over decades. It may have come from founding the firm, from inheritance, or from the slow purchase of a strategic stake. The family’s identity may be bound up with the shares. So may its ties to company management and its standing in the wider business world. Selling the shares, even in part, can feel like giving up more than a financial asset. Yet the practical strains of concentration are real. The family may need cash that its other assets cannot supply. Later generations may see risk differently. And estate planning may call for diversified trusts to be built over time.

Several factors set the loan-to-value ratio on a concentrated listed position. They include how liquid the shares are in the open market. They also include the size of the position against average daily trading volumes. The sector and geography of the issuer matter, as does the borrower’s overall financial profile. Some blocks are genuinely illiquid — selling them would take many months without moving the market. Here a specialist lender like Black Haven may offer a better LTV than a retail bank or prime broker. That is because Black Haven builds its facilities with a full grasp of the block-trade dynamic. The LTV is set to protect the lender against adverse price moves. At the same time, it gives the family real access to the value in their holding.

Black Haven treats family office relationships as long-term partnerships, not one-off transactions. A concentrated position is complex on many fronts. There are questions of governance and a succession-planning overlay. There are cross-border tax issues. And there is the family’s own relationship with the company. The financing must be designed with care, and it must adapt as circumstances change. Black Haven commits its own capital as principal lender. It keeps matters confidential, with the discretion that family clients require. It works alongside the family’s existing advisers rather than seeking to replace them. Every engagement starts with a confidential conversation. It covers the family’s aims and the nature of the position.
