Gross exposure is the total of long and short positions as a share of capital. Net exposure is long minus short: how much the portfolio leans on the market’s direction. Together they show how much is at work and which way it points.

How much is invested follows the evidence.

Why it matters. A fully invested stock account is 100% gross and 100% net: every move in the market passes straight through. A hedge fund running 150% gross and 20% net holds more positions than it has capital, but most of the market’s moves cancel out. Two portfolios with the same holdings can carry very different risk depending on these two numbers, and neither shows up on a pie chart of holdings.

The math. Gross = (long + short) ÷ capital. Net = (long − short) ÷ capital. On $10 million with $8 million long and $3 million short, gross is 110% and net is 50%. Cash counts as zero. Options count by delta, how much the option moves per dollar move in the stock: puts on $4 million of stock with a delta of −0.5 offset about $2 million of long exposure, and the offset grows as the stock falls.

How it’s applied in ASYMMETRY® Managed Portfolios. Exposure is the result of the process, not a target. A position is bought when its trend and the risk budget allow and sold when its exit is hit, so total exposure rises as trends confirm and falls as they break, toward cash when there’s no good opportunity. A hedge can lower net exposure without selling what’s owned.

Common misconceptions. Low net exposure isn’t low risk. A portfolio 150% long and 150% short is market-neutral on paper and can still lose heavily if its longs fall and its shorts rise. Gross exposure above 100% means leverage. And equal dollars aren’t equal risk: $1 million of a volatile stock can lose far more than $1 million of short-term bonds. Exposure tells you how much is at work. Predefined risk tells you how much can be lost.

Related terms. Predefined risk: what exposure doesn’t tell you. Beta: exposure weighted by sensitivity to the market. Tactical management, hedge funds, tail risk hedging and asymmetric leverage follow in the lexicon. Part of the ASYMMETRY® guide to asymmetric investing.
