A bad time to sell wild plums (5)

I believe the answer is:

slump

I'm a little stuck... Click here to teach me more about this clue!

'a bad time to sell' is the definition.
I can't tell whether this defines the answer.

'wild plums' is the wordplay.
'wild' indicates an anagram.
'plums' anagrammed gives 'SLUMP'.

Can you help me to learn more?

(Other definitions for slump that I've seen before include "Sit badly" , "Heavy fall" , "Sudden market drop" , "Marked decline" , "Deep recession" .)

I've seen this clue in The Globe and Mail.
