Fortune duly affected during shortage (4,4)

I believe the answer is:

lady luck

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

'fortune' is the definition.
I don't know anything about this answer so I can't judge whether this works.

'duly affected during shortage' is the wordplay.
'affected' indicates anagramming the letters.
'during' indicates putting letters inside.
'shortage' becomes 'lack' (a lack is a shortage of something).
'duly' with letters rearranged gives 'dylu'.
'dylu' placed within 'lack' is 'LADY LUCK'.

Can you help me to learn more?

(Other definitions for lady luck that I've seen before include "Female face of fortune?" , "Dame Fortune" .)

I've seen this clue in The Telegraph.
