Why this structure behaves this way
Cash-Secured Put is shaped by positive delta and short vega exposure
Positive delta from the short put means the position gains as the stock rises or stays flat. Theta is collected daily; IV contraction helps, and short gamma exposes the position to accelerating losses on a sharp drop.
