Who can grow their $100,000 to the most by the end of the semester? That is the challenge that my Personal Finance students must face in our Stock Market Challenge. While it is widely known that investing in the short term is somewhat driven by luck the process of researching a company, the process of buying the stock, and deciding whether you should hold or sell are great lessons to learn as a young adult. The Internet has allowed students to invest pretend money in a very life-like way. It often gets very competitive with my students to see who will be the winner at the end of December. I hope this activity gets students interested in their future and how their saving and investing rates can impact their life for the long term.
