ROBOCROBO Global Robotics and Automation Index ETF

WDRNBWisdomTree Physical AI, Humanoids, and Drones Fund

In short

ROBO Robotics as an index, since 2013. ROBO holds roughly 80 automation and robotics names worldwide and tracks the Robo-Stox index it was named for: long-tenured, broadly spread, and priced at the premium end of its group.

WDRN No data

Stated mandate

ROBO The Fund seeks to track, before fees and expenses, the price and yield performance of the Robo-Stox Global Robotics and Automation Index. It normally invests at least 80% of total assets in securities of that Index or related depositary receipts.

WDRN No data

Why people hold it

ROBO Trading since 2013 and now a billion-dollar-plus fund, with moderate day-to-day volume and one of the smoother execution profiles in the robotics cohort.
About 80 holdings spread across global markets, one of the better-diversified baskets in its peer group rather than a bet on three or four megacaps.
The prospectus pins at least 80% of assets to its named index, so you get a published rulebook for what counts as robotics, not a manager's rotating definition.

WDRN No data

Worth knowing

ROBO At 0.95% a year, it charges above the robotics-fund median (near 0.65%) and well above leaner builds like BOTT at 0.35% or IBOT at 0.47%.
One theme, many currencies. Robotics and automation stocks tend to move together, and the global holdings add exchange-rate swings on top.
Distributions land once or twice a year at most. This is a growth-theme equity basket, not an income holding.
