Tips from Amazon US holding good type of stock (5)
I believe the answer is:
angus
'stock' is the definition.
(I know that Angus is a type of cattle)
'tips from amazon us holding good type' is the wordplay.
'tips from' says to hollow out the word (remove centre letters).
'holding' says to put letters next to each other.
'good' becomes 'g' (abbreviation).
'type' indicates anagramming the letters.
'amazon' with its middle taken out is 'an'.
'us'+'g'='usg'
'usg' is an anagram of 'gus'.
'an'+'gus'='ANGUS'
'of' acts as a link.
(Other definitions for angus that I've seen before include "Lamb of God - . . . Dei" , "Scot" , "A snug breed from Aberdeen" , "Scottish cattle area" , "man" .)
