The more risk you take with an investment, the more money you will have a chance to make. However, big risk could also mean big loss.
Pretend you decided to buy shares for 5 apple trees instead of 1 because you thought they would do well.
If they all make 60 apples in year two, you will get 150 apples, not 30. BUT…If they all die in a winter storm, you will lose the money for 5 trees, instead of just 1. You have to decide if you want to take that chance.
