Summary
Investing.com UK reported a Form 4 insider filing for Blackstone Multi-Strategy Hedge Fund L.P. listing Riad M. Abrahams, who serves as Director and Chief Executive Officer, with a transaction date of October 22. Form 4 filings are required under U.S. securities rules when corporate insiders report changes in beneficial ownership, so the notice signals a reportable holding change for Abrahams in the fund's registered interests.

The same publisher and its Canadian edition carried related filings for other insiders at the fund. Director Philip Daniel Collins and Chief Compliance Officer William Simpson Gardiner were each the subject of Form 4 reports dated September 22. Taken together, the filings show activity among both board-level and compliance personnel at the vehicle over the reporting period.

The source material does not disclose the size of the transactions, the number of units or interests involved, or the price at which they occurred. Readers seeking those details should consult the underlying SEC filing directly.

Separately, Investing.com also published Form 4 notices for Ramin Kamfar, a director of Bluerock Private Real Estate Fund, covering September 21 and October 22. These relate to a different fund and are noted only as parallel insider-disclosure activity in the same syndication feed.
