Exposure
Exposure is how much of your money is affected by a change in a price: a $10,000 position has $10,000 of exposure even if you used only $1,000 of margin.
Margin tells you how much money you put down; exposure tells you how much is actually at stake when prices move. With leverage, the two can be very different. Exposure is also how professionals describe a whole portfolio: how much is long, how much is short, and what the net bet on the market is. This entry explains notional, gross and net exposure and how to keep them under control.

Exposure in plain words
If you control $10,000 of an asset, a 1% move changes your account by $100 — whether you paid $10,000 or borrowed most of it.1 That $10,000 is your exposure. See Leverage and Margin.
Across a portfolio, longs and shorts can offset each other. Net exposure is longs minus shorts; gross exposure is longs plus shorts. See Hedging.
How to measure exposure, step by step
Notional value per position
Quantity × price × contract multiplier.
Long exposure
Sum of all long notional values.
Short exposure
Sum of all short notional values.
Net exposure
Long − short: your overall directional bet.
Gross exposure
Long + short: total market activity, linked to leverage.
Compare with equity
Exposure ÷ account equity = effective leverage.
Worked examples
Example 1 — Margin vs. exposure
LeverageA trader posts $1,000 margin to control $10,000 of an index CFD. The index falls 5%.
| Margin | $1,000 |
| Exposure | $10,000 |
| Loss | $500 (half the margin) |
Losses follow exposure, not margin.2 See Contract for Difference.
Example 2 — Net and gross
PortfolioAccount $50,000. Longs $60,000, shorts $40,000.
| Net exposure | $20,000 (40% net long) |
| Gross exposure | $100,000 (2× equity) |
Low net exposure can still hide high gross leverage.
Example 3 — Hidden concentration
ConcentratedFive long positions in different tech stocks, $15,000 each.
| Sector exposure | $75,000 to one theme |
Group exposure by sector or theme, not just by ticker. See Correlation.
Types of exposure
| Aspect | Formula | Tells you |
|---|---|---|
| Notional | Quantity × price × multiplier | Size of one position |
| Net | Long − short | Overall direction |
| Gross | Long + short | Total size and leverage |
| Beta-adjusted | Exposure × beta | Sensitivity to the market. See Beta |
Why exposure matters
Leverage control
Exposure ÷ equity shows real leverage.
Risk limits
Caps on net and gross exposure.
Hedging
Reducing net exposure with offsetting positions.
Concentration checks
Spotting too much in one theme. See Diversification.
Advantages and disadvantages
Advantages
- Shows the true size of what is at stake.
- Reveals leverage hidden by small margins.
- Helps compare positions across products.
Disadvantages
- Notional numbers ignore how far stops are.
- Net figures can hide large gross positions.
- Correlation is not captured by simple totals.

Exposure vs. risk
Beginner
A $10,000 position with a stop 2% away risks about $200. Exposure is the size; risk is what you lose if the stop is hit. See Risk per Trade.
Options exposure
Intermediate
For options, delta-adjusted exposure (notional × delta) is a better measure of directional exposure than the premium paid. See Options.
Currency exposure
Advanced
Holding assets in a foreign currency adds exchange-rate exposure on top of the asset’s own price risk.
Common mistakes
Confusing margin with exposure
Losses follow exposure.
Counting tickers, not themes
Group correlated positions.
Watching only net exposure
Gross exposure drives leverage risk.
Ignoring currency exposure
Foreign assets carry FX risk.
