Situational Awareness filing shows AI bets before forced portfolio sale to Citadel

AI-focused hedge fund Situational Awareness has increased its stake in Japanese electronics manufacturer Taiyo Yuden by 11.62%, sending the company's shares higher. The US-based fund, founded by former OpenAI researcher Leopold Aschenbrenner, had been steadily building its position in Taiyo Yuden since late June and continued doing so through mid-July, according to regulatory filings.

Taiyo Yuden shares rose as much as 6.7% on Wednesday following Situational Awareness's disclosure of surpassing the 5% ownership threshold. This news came more than a month after the regulatory deadline, with additional filings released shortly thereafter revealing the fund's further stake increase. The investment is significant given Situational Awareness's recent struggles; the highly leveraged manager had to sell public equities last month following a sharp decline in technology positions.

Citadel, run by Ken Griffin, bought a substantial portion of the fund's AI-related holdings during that selloff. Taiyo Yuden has benefited greatly from the AI infrastructure boom, with the company manufacturing multilayer ceramic capacitors (MLCCs) crucial for servers and AI data centers. Its shares surged approximately 540% in the first half of the year, driven by expectations of sustained demand from AI-related infrastructure investments.

However, the stock has since retreated amid a broader reversal in AI-related trades, although it remains substantially higher than its year-to-date level. Situational Awareness's substantial new position suggests the fund remains optimistic about companies exposed to the AI infrastructure buildout, even amidst recent sector volatility.

The latest disclosure also follows Taiyo Yuden's share price plummeting to less than half its July peak, potentially presenting an opportunity for investors who believe the correction has gone too far.
