Delta Neutral
A position whose net delta is about zero, so direction barely moves its value.
Definition
Delta neutral describes a portfolio whose combined delta is close to zero. Because the positive and negative deltas of its legs cancel out, the position has little exposure to small moves in the underlying and instead profits or loses from other factors such as volatility and time decay.
Why it matters
Going delta neutral lets a trader express a view on volatility or time rather than direction. Sellers of straddles and strangles, for instance, are typically delta neutral at entry so they earn theta if the index stays calm. Buyers can be delta neutral to bet on a volatility expansion. The neutrality is rarely permanent — as price moves, gamma changes the net delta, so the book usually needs delta hedging to stay balanced.
Example
You sell one at-the-money Nifty call (delta about +0.50 to the underlying, so -0.50 to you as the seller) and one at-the-money put (delta about -0.50, so +0.50 to you). The two deltas roughly offset, leaving the short straddle delta neutral at the start. You now profit if Nifty stays near the strike and lose if it makes a large move in either direction.
Formula
Net delta = sum of (position delta x quantity) across every leg. A position is delta neutral when this sum is approximately 0.
