Linden Advisors LP's disclosed holdings carry a Herfindahl concentration index of 0.012 — mathematically equivalent to about 83 equally-sized positions, well below its 638 actual disclosed holdings. That gap points to a strategy built around a small core of high-conviction bets rather than broad diversification.
Position sizes vary widely across the portfolio (a coefficient of variation of 2.58), with a handful of outsized bets alongside many smaller positions.
No strong tilt toward either adding to existing winners or initiating outsized new positions was observed in the latest reported quarter.
Sector classification currently covers about 48% of this portfolio's disclosed value; the remainder includes holdings (e.g. unmapped tickers, options, or other security types) not yet covered by our sector mapping.

This quarter, LINDEN ADVISORS executed a clear rotation: it slashed or fully exited its LITE convertible positions (2028 and 2026 maturities), while actively adding to VSH, GH, and MKSI convertibles and initiating two small new positions. Elevated turnover (74.6%) confirms active repositioning rather than passive weight drift.
The shift away from LITE (optical communications) toward industrials, healthcare, and semiconductor equipment issuers may reflect a sector rotation tied to expectations about tech capex cycles or interest-rate sensitivity. However, with only this limited data, such a link is inferential, not confirmable.
With Information Technology commanding a 40.45% weight and several convertible positions concentrated in a handful of issuers, the portfolio's apparent diversification masks a concentrated credit/sector risk that could amplify drawdowns if tech-related convertible spreads widen unexpectedly.
