Key Takeaways:
AI hedge fund Situational Awareness cut its Taiyo Yuden stake to 4.41% from a 16.61% peak after a forced sale to Citadel.
"Buying Taiyo Yuden shares near Citadel's purchase price could yield profits," Tomoichiro Kubota, senior market analyst at Matsui Securities, said.
The fund, led by former OpenAI researcher Leopold Aschenbrenner, filed nine change reports with Japan's Kanto Local Finance Bureau on Aug 12 covering trading from late June through early August. It began accumulating shares on June 23, buying 1.5 million to 1.6 million daily to reach 5.99% by June 29, then kept buying even as the stock hit an all-time high of ¥24,000 on July 1. The stake peaked at 16.61% on July 22 before the fund sold about 1.8 million shares on July 28 and 30 to raise margin collateral, then executed a 14.64 million-share block trade — a 10.81% stake — at ¥9,963 a share on Aug 3, reducing its holding to 4.41% and exiting the 5% disclosure threshold.
Taiyo Yuden shares rose 7.51% on Aug 12, the top gainer among Nikkei 225 constituents, as investors bet the block trade price offered a floor. The company, a major producer of multilayer ceramic capacitors (MLCCs) used in AI servers, recently raised its net profit forecast for the fiscal year ending March 2027 by ¥11 billion to ¥29 billion, a 96% increase year-on-year, citing a book-to-bill ratio that approached 2 in July.
The rapid unwinding came as Situational Awareness faced a liquidity crunch after technology stocks plunged in July. The fund's assets under management fell to about $10 billion from $45 billion, forcing it to sell its public equity positions to Citadel at distressed prices, according to CNBC reports. The block trade on Aug 3 was the largest single disposal in the Taiyo Yuden position.
Ikuo Mitsui, fund manager at Aizawa Securities, said the stock's decline to less than half its July peak highlighted its valuation appeal, though he cautioned that concerns over MLCC supply-demand imbalances may limit long-term share price gains. Taiyo Yuden competes with Murata Manufacturing (6981.T) and TDK (6762.T) in the MLCC market.
The disclosure marks the end of a roughly six-week bet that began in late June. The fund's remaining 4.41% stake falls below Japan's 5% large-shareholding reporting threshold, meaning further changes may not be disclosed. Investors will watch whether Citadel, which absorbed the block trade, holds the position or unwinds it in coming sessions.
