Artisan Partners Asset Management Inc.
A global investment management firm, Artisan Partners runs a range of stock, credit, and alternative strategies for institutional investors, financial advisors, and individuals. It was founded in 1994 by Andrew and Carlene Ziegler, who built it around autonomous investment teams that each follow their own distinctive approach. The name reflects that "artisan" philosophy — treating investing as a craft practiced by specialized, independent experts rather than a one-size-fits-all process.

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 all recorded history: -2.47M shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
