Planning a four-month portfolio challenge from December through March? Here's a structured approach: dividing your positions across three market cap tiers—top 50 by market cap, the 51-150 range, and projects beyond 150—creates nice diversification across established and emerging plays. The real opportunity sits in that 51-150 sweet spot though. This tier often gets overlooked by retail but typically shows outsized volatility during bull runs. You're hunting for assets with solid fundamentals that haven't peaked yet on the hype cycle. Think projects with active development, genuine adoption, or those positioned to benefit from the next wave of interest. For a December-to-March window, you'll want to balance between proven performers and calculated risks. The mid-cap range specifically tends to reward patient investors who spot momentum before it becomes consensus.
