AI Analysis · Q4 2025

Teilinger Capital's $1.93B Q4 2025 13F is not a rebalanced book — it is a rebuilt one. The filer exited its entire utility-forward structure (Entergy, NextEra, PG&E) and deployed the proceeds into three concentrated growth names: Tesla at 70.2% of the portfolio, Micron at 12.9%, and an Alibaba position that was tripled to 11.9%. The Q/Q data is real and unambiguous: only one of twelve holdings — PPL Corp — survived the quarter unchanged. The whaleScore of 75 does not reflect diversification here; it reflects how large a single-stock bet is when the manager puts $1.35B behind it. The risk is symmetrical: a negative Tesla earnings surprise, a regulatory setback, or a macro-driven growth rotation reprices the entire book in a single session.

Teilinger Capital's Q4 2025 13F reads like a mandate change, not a quarterly update. The previous filing held eight positions, almost all utilities, with a total value of $115M. The current filing holds twelve positions, almost entirely growth/tech, with a total value of $1.93B. That is a 16x AUM increase plus a complete sector rotation compressed into a single quarter. Only PPL Corp survived unchanged — and even then, its share count rose 87% as the manager added to a position that was already 3.7% of the prior book.
