Provides Joe with a share in investment (5)

I believe the answer is:

gives

I'm a little stuck... Click here to teach me more about this clue!

'provides' is the definition.
(giving is a kind of providing)

'joe with a share in investment' is the wordplay.
I cannot quite understand how this works, but
'joe' could be 'gi' (GI Joe) and 'gi' is found in the answer.
This explanation may well be incorrect...

Can you help me to learn more?

(Another definition for gives that I've seen is " Donates".)

I've seen this clue in the Evening Standard.
