AI Analysis · Q1 2026

Quanta Services' CUSIP was reissued this quarter, and D L Carlson Investment Group's stake came out the other side at 11,527 shares — just 65 more than the 11,462 it held before. That near-total stillness, buried inside what looks like a full sell-and-rebuy, is the quietest data point in an otherwise active 135-position, $581.8 million book. It also hints at the firm's real discipline: a deliberate bond-duration shortening, with a real $4.4 million cut to the IGIB intermediate-corporate ETF funding real adds to the short-duration IGSB (+17.5%) and GVI (+8.9%) funds. On the equity side, RTX Corp's own CUSIP reissuance masks a genuine 13.3% share reduction, while Microsoft (-12.6%) and Amazon (-14.5%) saw real trims alongside fresh adds to Tesla, GE Aerospace, and Netflix.

The real story is duration, not any single stock

That same discipline shows up with more consequence on the fixed-income side. D L Carlson made a genuine, deliberate shift toward shorter bond duration this quarter: the iShares Intermediate Corporate Bond ETF (IGIB) was cut 37.1% in share terms, a real $4.4 million outflow — the single largest real sale anywhere in the book — while the iShares Short-Term Corporate Bond ETF (IGSB) grew 17.5% (a real $1.8 million buy) and the iShares Intermediate Government/Credit fund (GVI, despite its name a shorter-duration-tilted holding here) grew 8.9% (a real $4.4 million buy, now the portfolio's second-largest position at 9.3%). The broader Aggregate Bond ETF (AGG) was also trimmed 10.3% in real terms. Read together, that's not passive drift — it's an active decision to shorten the bond ladder.
