Details circulating to Raul, an investor (10)
I believe the answer is:
speculator
'an investor' is the definition.
The answer and definition can be both people as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'details circulating to raul' is the wordplay.
'details' becomes 'spec' (I am not sure about this - if you are sure you should believe this answer much more).
'circulating' indicates anagramming the letters.
'to'+'raul'='toraul'
'toraul' with letters rearranged gives 'ulator'.
'spec'+'ulator'='SPECULATOR'
Can you help me to learn more?
(Other definitions for speculator that I've seen before include "Stock market gambler" , "better" , "One gambling on the stock exchange" , "Investor in stocks, etc" .)
