NAV premium / discount

A BDC's NAV premium or discount is the gap between its share price and its net asset value per share. A BDC with a $15.00 NAV trading at $13.50 sits at a 10% discount; the same BDC at $16.50 trades at a 10% premium. Because a BDC is essentially a portfolio of loans in a listed wrapper, this gap is the market's real-time verdict on the portfolio's stated value — and on the manager's ability to grow it.

Persistent discounts usually encode one of three judgments: the market believes the marks are optimistic (stated NAV overstates what the loans would fetch), it expects credit losses ahead of what's reserved, or it discounts the management — fees too high, underwriting record too weak. Premiums encode the reverse: confidence in the marks plus a franchise the market believes can originate above-market returns. Sector-wide discount waves also happen — in risk-off periods the whole BDC space can trade 10-20% below NAV regardless of individual quality.

For analysts, the premium/discount is most useful cross-sectionally and against mark quality. A BDC trading at a deep discount while marking its book near par is making an implicit claim the market disputes — and comparing its marks on shared credits against peer marks on the same credits is one of the few direct ways to test who's right. A discount paired with peer-consistent marks reads very differently from a discount paired with marks that sit above every peer's.

SpreadVista tracks NAV per share across 86 BDCs from their own filings and pairs it with position-level mark comparison, so the "is the discount justified?" question can be answered with the credit-level evidence rather than sentiment.
