Dollar Neutral Portfolio Interview Guide

Dollar neutral portfolio interview guide covering long dollars, short dollars, gross exposure, net exposure, risk, and examples.

Candidates discussing long-short construction and gross/net exposure.

Dollar neutrality balances long and short value

A dollar-neutral portfolio has roughly equal long and short dollar exposure, making net dollar exposure close to zero by design.

Gross exposure still creates leverage

A portfolio can have zero net dollars but large gross exposure, which magnifies spread moves, financing needs, and drawdowns.

Concrete example

A book long 100 million dollars of stocks and short 100 million dollars is dollar neutral but has 200 million dollars gross exposure.

Dollar neutrality is not beta neutrality

Long and short sides can have different beta, volatility, sector exposure, liquidity, and borrow costs even with equal dollars.

Common mistakes

Candidates often stop at net exposure. Always discuss gross exposure, factor exposure, financing, and short constraints.
