Answer:
40%
Step-by-step explanation:
The computation of the Nico's realized holding period return is shown below:
= (End year price - beginning year price + dividend per share at the end of 2018 + dividend per share at the end of 2019 + dividend per share at the end of 2020) ÷ (beginning year price)
= ($33 per share - $30 per share + $2 per share + $3 per share + $4 per share) ÷ ($30 per share)
= ($12 per share) ÷ ($30 per share)
= 40%
