<prompt> Human: About 10 years ago my grandfather passed away and my brother and I inherited a large sum of money in stocks for the company he worked for. I was not allowed to touch the money until I turned 21, which I will be in a couple months. So Im wondering if it would be better to just leave the stocks alone and hope they grow in value, or if there is a better place to put that money so it builds interest faster?  <response>: If you had the value of the stocks in cash, would you invest it all in your grandfathers company?
