Castleark Management Actively Adjusts Portfolio, Trimming Kratos and Adding Tower Semiconductor

Castleark held 109,634 KTOS shares, about 0.06% of Kratos Defense, worth roughly $7.73 million; hedge funds and institutional investors collectively own about 75.92% of KTOS.
Tower Semiconductor has a hedge-fund-heavy ownership base, with 70.51% of its stock held by hedge funds and institutional investors; multiple analysts issued new ratings/targets (Benchmark: Buy; Susquehanna: target $330; Wedbush: target $300; UBS: Buy).
Toll Brothers dividend update: Toll Brothers disclosed a quarterly dividend, which was paid on Friday, July 24.
iShares 20+ Year Treasury Bond ETF (TLT) is highly institutional-owned, with 73.33% of its stock held by institutional investors.
Castleark Management LLC made a series of notable portfolio moves in the first quarter, cutting its stake in Kratos Defense & Security Solutions by 28.3% while opening a brand-new position in Tower Semiconductor. The Chicago-based hedge fund now holds about 109,600 shares of Kratos worth roughly $7.7 million, and picked up 53,240 shares of Tower Semiconductor for about $9.34 million, according to Ticker Report.
The trades signal an active reshuffling across defense, semiconductors, homebuilding, and Treasury bonds. Castleark did not sit still in any single sector — it added, cut, and opened positions across multiple asset classes in the same quarter.
Castleark sold 43,600 shares of Kratos Defense, trimming its position by 28.3%. The remaining 109,634 shares are worth about $7.73 million. That stake represents just 0.06% of the company. Kratos is heavily owned by big investors — hedge funds and institutions together hold about 75.92% of all KTOS shares, according to Ticker Report.
Despite the trim, Kratos remains in the portfolio. The defense sector has drawn strong investor interest as global military spending rises. Castleark appears to be sizing down rather than walking away entirely.
Castleark's new Tower Semiconductor position — 53,240 shares worth $9.34 million — comes as Wall Street turns bullish on the stock. Benchmark rates it a Buy. Susquehanna set a price target of $330. Wedbush set a target of $300. UBS also rates it a Buy, according to Ticker Report.
Tower Semiconductor has a heavily institutional ownership base. Hedge funds and institutional investors control about 70.51% of the company's shares. Castleark's new stake puts it in good company — many large funds are betting on the chipmaker's growth.
Castleark grew its position in the iShares 20+ Year Treasury Bond ETF — known by its ticker TLT — by 45.2%. It now holds 137,270 shares worth about $11.9 million. TLT tracks long-term U.S. government bonds. Institutional investors own about 73.33% of TLT, according to Ticker Report.
On the other side of the ledger, Castleark cut TTM Technologies by 30.8%, dropping to 91,230 shares valued at roughly $8.9 million. The fund trimmed TTM while it was building up bond exposure — a possible sign it expects interest rates to fall, which tends to push long-term bond prices higher.
Castleark also boosted its Toll Brothers position by 25.1%, bringing total holdings to 51,403 shares worth about $7.0 million. The homebuilder paid out its quarterly dividend on Friday, July 24, according to Watchlist News.
The move into Toll Brothers comes alongside broader bets on rate-sensitive assets like TLT. Lower interest rates tend to help homebuilders by making mortgages cheaper. Castleark's simultaneous buys in both sectors suggest it may be positioning for a rate-cutting environment ahead.
