The case for holding various shares (9)
I believe the answer is:
portfolio
This might be a double definition.
'the case' is the first definition.
(portfolio is a kind of case)
'holding various shares' is the second definition.
'portfolio' can be an answer for 'shares' (I've seen this before). I'm not sure about the 'holding various' bit.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for portfolio that I've seen before include "Carrying case for documents" , "Set of collected pieces of creative work" , "governmental responsibility" , "responsibility of minister" , "minister's office" .)
