Best way to grow 100k-300k? (already in the 20-24% tax bracket)

[Josh Brekke]

If I'm already in the 20-24% tax bracket, what would be the best way to grow 100k-300k while minimizing the tax burden (while keeping it somewhat liquid)?  I thought about putting it in the market, and hold it long-term (just over a year, maybe longer).

Thanks,

Josh
