In the filing, Citadel disclosed ownership of 573,691 shares. The initial public offering of Cherry Hill Mortgage Investment Corporation involved around 6.5 million shares of common stock at a price of $20 per share and ended last Wednesday.
Update: In a series of Form 4 filings just reported, Citadel has made a few changes in its Cherry Hill stake. After briefly upping its position above 600,000 shares, Griffin's firm now reports that it owns 400,000 shares. This represents a little over 5% of Cherry Hill's outstanding shares.
