Capital ~30k, shorter term, higher risk for growth, what would be your go to strategy?

hi everyone, hypothetical scenario: you have $30k to invest with a shorter time horizon (<5 years). what approaches would you consider?

questions i’d love input on:

1. with a short term horizon, what kinds of investments are even reasonable for a risk-tolerant strategy? (broad index etfs, sector etfs, small cap, individual stocks, etc.)
2. how do you think about risk management over a short timeframe?
3. would you invest lump sum vs. dca in this case, and why?
4. what are common traps when chasing higher returns on a short horizon?
