What happens if the market drops 10%?
A risk question asks how much of a portfolio depends on one thing going right — a single position, a sector, a country. Concentration is read as a share of the total, which is what the figures below show.
Worked through on a sample portfolio. The figures below are that portfolio’s, not yours.
I ran a scenario that applies a uniform -10% shock to market-exposed holdings today (your current holdings at their current values). Assumptions:
- Shock: Equities and ETFs: -10%; Crypto: -10% (applied to Crypto holdings); Precious metal: -10%; Cash unchanged.
- Applied to today's holdings at their current market values.
- No buying or selling during the scenario; exchange rates unchanged; no dividends or fees.
Result (hypothetical): your portfolio value would fall from 90.983,96 € to 82.885,56 € (a change of -8.098,40 €).
Table — impact by asset class
| Asset | Value (€) | Change (€) |
|---|---|---|
| Stock | 44.666,25 € | -4.466,63 € |
| ETF | 28.397,93 € | -2.839,79 € |
| Crypto | 7.833,76 € | -783,38 € |
| Precious metal | 4.575,79 € | -457,58 € |
| Cash | 5.510,23 € | 0,00% € |
What it means: in this scenario the total hypothetical loss is -8.098,40 €, driven mainly by the stock and ETF holdings. Cash cushions the drop because it is unchanged.
Would you like me to run a different shock (for example equities -20%, crypto -30%)?
