Speculator initially selling tin and gold (4)

I believe the answer is:

stag

'speculator' is the definition.
(type of stock market speculator)

'initially selling tin and gold' is the wordplay.
'initially' suggests taking the first letters.
The initial letters of 'selling tin and gold' is 'STAG'.

(Other definitions for stag that I've seen before include "Deer; with only men" , "Male-only" , "speculator wanting quick profit" , "Hart" , "Male animal" .)

I've seen this clue in The Times.
