Modular Wealth: Building Your Portfolio in Blocks

A professional portfolio isn't a random collection of stocks; it's a modular system designed for specific outcomes.

Core Blocks (70-80%)

This is the foundation. Index funds, large-cap equities, and high-quality debt. Its job is to grow steadily with the economy and provide stability.

Satellite Blocks (20-30%)

This is the growth engine. Sectoral funds, mid-caps, or individual stock picks. This block has higher risk but offers the potential for 'Alpha' (outperforming the market).

The Boundary Layer

Cash and short-term debt acting as the buffer between your life expenses and your long-term wealth blocks. This separation prevents emotional selling during market drawdown events.
