Open interest is distinct from volume: volume counts how many contracts are traded in a session, while open interest counts how many remain open at the end of the day. Rising TBLU options open interest alongside rising volume suggests new positions are being built, while falling open interest signals positions are being closed. Heavy open interest at specific strikes often acts as a magnet near expiration and can hint at where dealers and large traders expect Tortoise Global Water ETF to settle.

TBLU offers exposure to developed-market all-cap water companies.

Water equipment companies are those who provide water pipes, valves, pumps or water efficiency products such as filtration, treatment, and testing of water. Service companies provide technologies that facilitate management of water distribution, usage, treatment, and irrigation.
