A change is this filing measured against the one before it. A 13F does not disclose trades, so the price paid and the day it happened are not in the record.
Questions
What does HBK Capital Management hold?
HBK Capital Management disclosed 276 positions worth $10.2B in the Q2 2026 13F filing. The largest is BLD at 9.1% of the disclosed book. A 13F lists long US equity positions only.
What did HBK Capital Management buy and sell last quarter?
Comparing the Q2 2026 filing with the quarter before, the largest moves were New BLD, Exited HOLX, New TECH, Trimmed NVDA. Changes are measured against the previous filing, not against trades, because a 13F does not disclose trades.
How current is this?
This is the Q2 2026 filing, covering positions held on Jun 30, 2026. A 13F is due 45 days after the quarter ends, so the most recent filing is always at least six weeks behind the market, and the manager may have changed the book since.
