To Sell or Not to Sell

A friend of mine, SY, asked whether she should sell off her ING Annual Income Climate Structured Fund yesterday as her net profit is approximately 16%+ in 8 months+/-. What do you think?

Me - I asked for more information like:

1. What kind of fund is it?
   Her response: Capital protected fund with guaranteed minimum returns of 5% per annum for 3 years.
2. What was her goal / intention when getting into that fund?
   Her response: For income generation + a possibility of bettering 5% pa.
   
3. Any ideas / opportunities for the lump sum money if redeemed / sold off?
   Her response: Yup.
4. Hungry for much better returns than the current if sold/redeemed now?
   Her response: Nope

 Hehehe - after asking the above questions, she herself already answered her own question of whether to hold or sell / redeem. Sometimes, I think it's not that we do not know the answer we seek, but we may have asked ourselves the wrong question or lost our targets / goals / reasons for getting into something (not just investments) ;P.

What other questions would you have asked?
