Alliancebernstein Holding L.p.
A global asset-management and investment-research firm, AllianceBernstein manages mutual funds, separate accounts, hedge funds, and other investments for institutions like pension plans and insurance companies, as well as wealthy individuals and everyday retail investors. The firm was born from a 2000 merger between Alliance Capital Management and Sanford C. Bernstein & Co., the Wall Street firm founded in 1967 by Sanford Bernstein. A fun twist: that founder famously lived "two lives"—after his father's death he became a deeply observant Orthodox Jew and adopted his Hebrew name, Zalman Chaim Bernstein.

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 3 years: +20.76M shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
