UBS OCONNOR A Shifts Holdings, Acquiring TE Connectivity and Wabtec, Trimming Delta and Vertiv

OCONNOR A Distinct Business Unit reported that after trimming Delta Air Lines by 49% it held 58,731 shares, having sold 56,417 shares in the quarter; the position was valued at about $4.076 million in its most recent SEC filing. The article also notes 69.93% of Delta stock is held by institutional investors.
For Cameco, the article adds company-specific context: it cites a debt-to-equity ratio of 0.14, a quick ratio of 2.09, and a current ratio of 3.08, along with a listed market cap of about $46.59 billion and a price-to-earnings ratio of 99.04.
TE Connectivity: the report includes an insider transaction, stating that insider Shadrak W. Kroeger sold 9,400 shares at an average price of $215.00 (total value $2.021 million). After the sale, the insider reportedly owned 25,976 shares.
Wabtec: the article also reports an insider sale by CEO Rafael Santana—selling 1,163 shares at an average price of $261.06 (total proceeds shown as $...), with the transaction dated Monday, June 8.
Vertiv: beyond generic “buy” coverage, the report specifies price targets and ratings—Roth Mkm reiterated a “buy” and set a $355.00 target, while Morgan Stanley raised its target to $350.00 from $285.00 and maintained an “overweight” rating.
UBS Asset Management Americas' O'Connor unit has taken a new $5.67 million stake in TE Connectivity, buying 26,355 shares, while also entering Wabtec for the first time with 10,000 shares worth roughly $2.61 million, according to Watchlist News. The moves came as the same unit slashed its Delta Air Lines position by 49% and cut its Cameco holding by nearly 85%.
The filings paint a clear picture: O'Connor is rotating out of high-flying sectors like nuclear energy and AI data centers, and into industrial components and rail logistics infrastructure.
O'Connor cut its Cameco stake by 84.9%, leaving just 7,138 shares worth about $653,000, according to Watchlist News. Cameco trades at a price-to-earnings ratio of 99.04 and carries a market cap of roughly $46.59 billion. Despite strong liquidity — a current ratio of 3.08 and a quick ratio of 2.09 — O'Connor appears to view the valuation as stretched after the uranium sector's two-year rally.
The unit also cut Vertiv by 77.1%, reducing its stake to 22,057 shares. It sold off roughly 74,200 shares during the quarter. That exit came even as Morgan Stanley raised its Vertiv price target to $350.00 from $285.00 and kept an "Overweight" rating. Roth MKM went further, reiterating a "Buy" and setting a $355.00 target. O'Connor's move suggests it believes the easy gains in AI data center stocks are already behind them.
O'Connor's new 26,355-share stake in TE Connectivity is valued at approximately $5.67 million. TE Connectivity makes connectors and sensors used in electric vehicles and high-speed data systems — the "picks and shovels" of industrial modernization. The unit also added 10,000 shares of Wabtec, a rail equipment maker, worth about $2.61 million. Both are first-time positions, signaling a deliberate shift toward hard industrial infrastructure.
The timing is notable. Wabtec CEO Rafael Santana sold 1,163 shares at $261.06 each on June 8, even as O'Connor was building its new position. At TE Connectivity, insider Shadrak W. Kroeger sold 9,400 shares at $215.00 per share — a $2.021 million transaction — leaving him with 25,976 shares. Insider sales are often pre-scheduled, but the simultaneous buying by O'Connor and selling by executives creates a visible contrast in short-term conviction.
O'Connor cut its Delta Air Lines position by 49%, selling 56,417 shares and keeping 58,731. The remaining stake is worth about $4.076 million. The move stands out because 69.93% of Delta's float is held by institutional investors — and many of them are moving in the opposite direction, adding to their positions rather than cutting.
The split reflects a broader debate about the airline sector. O'Connor appears to be hedging against a possible consumer slowdown. Other large institutions, by contrast, are betting that international travel demand stays strong. Neither side has made a definitive call — the divergence simply shows that smart money is not reading the same playbook right now.
Taken together, O'Connor's trades tell a coherent story. The unit is locking in profits from sectors that have already had big runs — nuclear energy, AI cooling systems, and airline recovery plays. It is redeploying that capital into companies tied to re-industrialization: rail infrastructure and electronic components for EVs and data transmission.
If other hedge fund units follow O'Connor's lead out of Vertiv, the stock could hit a ceiling despite the bullish analyst targets. Cameco's near-85% reduction may also signal a cooling period for uranium stocks more broadly. For now, the filings show one well-resourced unit making a clear, directional bet — away from hype and toward hard infrastructure.
