Explanation

Let's analyze the risk characteristics:

Gamma-negative positions: These are short gamma positions (typically short options). Gamma-negative positions are exposed to large losses from large price movements in either direction.

Delta-positive positions: These are long positions in the underlying asset, exposed to directional risk if prices decline.

Gamma-negative, delta-positive (Option C): This is the most dangerous combination because:

• Gamma-negative means the position loses money from large price movements
• Delta-positive means the position is already long the underlying
• If prices decline significantly, the delta-positive position loses value, and the gamma-negative position amplifies these losses

Other positions:

• A: Gamma-negative, delta-neutral - risky but less than C
• B: Gamma-positive, delta-positive - less risky as gamma-positive provides some protection
• D: Gamma-positive, delta-neutral - least risky among these

Correct Answer: C
