Cubesmart
A real estate investment trust that owns, operates, and manages self-storage properties across the country, CubeSmart runs a network of about fifteen hundred stores under its own brand and for third-party owners. Founded in 2004 by brothers Robert and Barry Amsdell, it originally went by the name U-Store-It Trust before rebranding to CubeSmart in 2011 — a nod to renting out the cubic space where people stash their stuff. It offers moves with its own moving supplies, trucks, and packing boxes for households and small businesses.

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: -5.75M shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
