03 Risk Analysis Standing by

Read the risk in this portfolio

Correlation, concentration, volatility, the worst dip it actually took, and which holdings drive the risk — from about two years of real daily closing prices.

Add at least 2 holdings

Risk Drivers?Each holding’s share of your portfolio’s total volatility — its weight combined with how it moves against the rest of the portfolio. A small position that swings hard, or that moves in lockstep with everything else, can drive far more risk than its size suggests.

Which holdings actually generate your risk — and how many independent bets you are really making.

Correlation?Whether your holdings tend to move together (near +1) or independently/oppositely (near 0 or −1) on a given day. Real diversification means LOW correlation — holdings that don’t all rise and fall in lockstep.

How your holdings move relative to one another — low is real diversification.

Concentration?How much of your portfolio depends on a single stock or sector. The more concentrated, the more one company’s — or one industry’s — bad day can hurt your whole portfolio.

How much rides on your single largest position and sector.

Volatility?How much your portfolio’s value swings up and down, annualized. Higher means bigger price swings — not necessarily bigger losses.

How much the whole portfolio swings, annualized — and each holding’s share.

Worst Dip & Its Context?A drawdown is the drop from a peak value to the lowest point that follows. This is the single worst such drop found across your portfolio’s ~2-year price history — one specific past stretch, not a forecast and not a score.

The deepest peak-to-trough drop over ~2 years of real prices — with when it happened and how it recovered.
