In review, share stocks lose badly for play writer (3,7)

'in review share stocks' is the definition.
The definition suggests a singular noun which matches the answer.

'lose badly for play writer' is the wordplay.
I cannot really understand how this works, but
'for' could be 'to' (eg both can mean 'in the opinion of') and 'to' is present in the answer.
an anagram of 'lose' is 'eols' which is located in the remaining letters.
'play' could be 'toy' (synonyms) and 'toy' is found within the answer.
A single letter 'l' remains which might be clued in a way I don't see.
This may be the basis of clue (or it may be nonsense).

Can you help me to learn more?
