AI Analysis · Q3 2026

Byrne Asset Management's $185 million Q2 2026 thirteen-f book is defined by the most asymmetrical change profile in the current cohort: 45 positions reduced and zero increased, while the portfolio still grew by $14.4 million. The reason every major holding posted a positive dollar change despite a decreased classification is that the market did the work — tech and cyclicals rallied so sharply that reduced share counts still translated into higher book values. AMD, Applied Materials, and Corning were the largest notional decreases by absolute value, each declining in shares but rising by $1.9–$2.9 million in value; I am excluding them from the flow narrative because the direction contradicts the change-type classification. Against that backdrop, four genuine new positions — Micron, KKR, American Express, and Qualcomm — were initiated, replacing gold, healthcare, and legacy telecom exposure.

What did the manager actually do? It initiated four new positions: Micron ($2.2 million), KKR ($1.0 million), American Express ($1.0 million), and Qualcomm ($1.0 million). These are semiconductor, private-markets-adjacent, financial-services, and wireless names — a blend that suggests the portfolio is rotating out of passive-sleeve proxies into higher-conviction single stocks. On the exit side, the portfolio sold SPDR Gold Shares ($1.7 million), Abbott Laboratories ($1.2 million), GE Healthcare ($1.2 million), and AT&T ($1.1 million). The gold sale is the most notable: GLD had been held for income and was cleared at what looks like a deliberate repositioning. The exits from Abbott and GE Healthcare remove two healthcare names that had been steady holdings.

The sector picture is heavily weighted toward technology — roughly 26% of assets — with financial services a distant second at 10%. Industrials, healthcare, and basic materials each sit between 6% and 7%. The one clear ETF holding, VOO, is just 1.2% of the book. This is not a platform sleeve; it is a deliberate single-stock portfolio. The whaleScore of 46.50 is toward the lower end for active managers in this cohort, which makes sense: 594 names dilutes concentration relative to a tighter book, but the top 20 still carry meaningful weight.
