The largest dollar stake in XFOR belongs to Morgan Stanley, but the position matters far more to Empery Asset Management, LP, who has 37.4% of their own portfolio riding on it — a reminder that the biggest holder by size and the holder with the biggest bet aren't always the same fund.

XFOR
Q2 2026
Top 5 Institutional Movers
XFOR does not currently have enough recent insider (Form 4) trading activity to compute a convergence signal against its 13F institutional flows.
13F data as of 2026-09-30 quarterly filings. Note: many large institutions file close to the 45-day post-quarter deadline, so early-quarter flow figures can shift substantially as more filings arrive.
