Single-Stock Concentration Risk Calculator
When one position (RSUs, founder stock) dominates — its share of net worth and the drawdown it can inflict.
Formula
Tech employees routinely hold 40%+ of net worth in one employer's stock — the same company paying their salary, so job and portfolio crash together. Disciplined diversification (10b5-1 plans, collars, exchange funds) beats the lottery-ticket hope. The first 10% sold always feels too early and rarely is.
