OPULION

The universe under watch

The investment companies we follow

Seventeen listed investment companies, two readings of one set: the globe places each head office, the table compares them fact by fact. Every discount is measured on published NAV, dated and sourced; no price target, no directional signal.

Seventeen head offices, one universe

From Stockholm to Omaha, every company is pinned at its head office. The table below gives the same reading, complete and accessible.
