Would like to differ respectfully here. My point based on the above scenario - there is no risk of re-investing here as once you are through with 30-40% CAGR for 2-3 years invest that money into the 10 yr 20% compounder straight away. right? More money at the end of the day. So I would invest in 30-40% company for 2-3 years and buy the 20% compounder at the end of 3rd year.
Anyway, different opinions make investors!
