A $31.20 billion industrial-sector fund made a rare clean sweep on Oct. 29, 2026, adding to every single one of its positions without trimming a single share.

State Street Industrial Select Sector SPDR ETF (NYSEARCA: XLI) deployed $178.6 million across all 83 of its holdings in one session, with its gross traded total precisely matching its net purchased figure.

The absence of any reductions means the fund expressed uniform conviction across the entire portfolio, a pattern that investors will be watching to see if it holds in subsequent sessions.

General Electric (GE) attracted the largest single allocation, with XLI purchasing 34,293 shares worth $10.7 million, lifting GE’s weight within the fund to 6.01%.

Caterpillar (CAT) ranked second among the session’s largest buys, drawing $9.8 million through 15,204 additional shares, giving it a 5.51% weighting in the portfolio.

RTX Corp (RTX) came in third at $8.9 million, representing 44,541 shares added and a 4.97% position within the fund.

GE Vernova (GEV) and Union Pacific (UNP) rounded out the five largest purchases, attracting $7.8 million and $5.9 million respectively, with GEV at 4.38% and UNP at 3.32% of total assets.

None of the five largest purchases represented new entries into the portfolio, meaning the fund was deepening existing exposures rather than diversifying into fresh names.

XLI concentrates its top 10 holdings at 37.5% of total assets, with industrials comprising 93.1% of classified stocks, technology at 6.3%, and basic materials at just 0.4%.

The fund is overwhelmingly oriented toward large-cap companies, which account for 99.9% of its market-cap mix, and it carries a lean expense ratio of 0.08%.

On valuation metrics, XLI trades at a price-to-earnings ratio of 28.07 and a price-to-book ratio of 6.21, with a dividend yield of 1.09%.

The fund has posted a year-to-date return of 8.78% and carries a GF Score of 82 out of 100, reflecting solid but not exceptional composite quality ratings.

On the day of the purchases, XLI itself gained 1.91%, while GE rose 4.23% and GEV climbed 4.25%, suggesting favorable momentum aligned with the fund’s heaviest buying activity.

The key question for investors is whether XLI sustains this across-the-board accumulation pattern or begins to show selective trimming as its largest positions grow relative to their target weights.
