Surrender return on investment (5)
I believe the answer is:
yield
I believe this clue is a double definition.
'surrender' is the first definition.
(yield can mean to give up or surrender)
'return on investment' is the second definition.
(I've seen this in another clue)
(Other definitions for yield that I've seen before include "volte-face" , "Stop defending" , "Supply" , "Render" , "Income" .)
