Isn't any investor who's not just buying an index fund a value investor by that broad definition?

(Even shortsellers just say: this stuff is worth less than the market says.)

As opposed speculator. "It's going up, i just know it." Or market makers, or technical analysts, or reading tea leaves...etc

Value investor suggests you have valued the assets and have reason for thinking they are underpriced. Shareholders own the company's assets. Managers are their employees and are not owned any more than any employees or indeed humans are owned.
