Sector Exposure

// Concentration Risk

Any single position above 20% of portfolio is considered concentrated. Above 33% is high risk — one bad trade can materially damage overall performance.

// Sector Exposure

Heavy allocation to one sector means economic sector events hit your whole portfolio simultaneously. Aim to diversify across uncorrelated sectors.

// Heatmap Colours

Green tiles = in profit. Red tiles = at a loss. Larger tiles = bigger allocation. A healthy portfolio shows mostly green tiles of balanced sizes.

// Rebalancing

When one position's allocation drifts far above target due to price appreciation, consider trimming to rebalance and realise some of the gain.
