Lubber, the increase in volatility immediately prior to expiry, followed by the decrease immediately afterwards happens to all stocks. And indices. I'm not aware that anybody uses this technique routinely.

Where I do use this phenomena is with higher priced, more volatile stocks. I buy the underlying, write both puts and calls. If the underlying turns south, I sell the long stock and then short it, as protection against the short put. This technique is profitable mostly for high-priced, very volatile stocks.

Meanwhile, I'm looking forward to the answers to your question about "what margin is required for short puts."

Good trading, Glen
