One of the world's largest alternative asset managers, Blackstone invests money on behalf of pensions, insurers, and wealthy individuals across real estate, private equity, credit, and more. Founded in 1985 by Stephen Schwarzman and Peter Peterson, former Lehman Brothers colleagues, its name is a clever mashup of the two founders' names—"black" from the German for Schwarzman and "stone" from the Greek for Peterson. That naming quirk dodged the Wall Street tradition of just stacking two surnames on the door.
Select a row to see that insider’s individual transactions. † Sum of the holdings confirmed in the 12 months before this insider's last filing. A Form 4 reports a holding per line — held directly, or through a named trust, partnership or foundation, and in each share class separately — never a person’s total. Lines not restated in that time are left out and shown apart: an active filer restates what they still hold, so a line they did not restate is more often an entity since renamed, whose shares a successor line reports too. An amber marker means some were left out.
Net open-market activity over the last 5 years: -10.35M shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
