Shareholders quick to move? (5)
I believe the answer is:
hares
'shareholders' is the definition.
Although both the answer and definition are plural nouns, I can't see how one could define the other.
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for hares that I've seen before include "Share of wild animals" , "Swift long-eared mammals" , "Fleet-footed animals" , "Fast animals" , "Long-eared animals" .)
