WisdomTree Copper ETF - COPA - Share Chat

This ETF aims to track the Bloomberg Copper Subindex and provide a collateral yield.

What exactly does that mean?

Curiously Bloomberg is also the name of the agency that supplies my carers.
Nice ladies all of them, good at their jobs most of them.
I doubt it is the same Bloomberg as here. I have noted that care companies pick names that they think will be identified as reliable and British.

Bloomberg is named after Michael Bloomberg - an American billionaire and founder of the respective financial information company. Nothing British here.
Companies are often named after well-known larger companies to fake trustworthiness and success.

Bloomberg doesn’t even sound remotely British. Sounds German to me. Like a flower on a mountain.
