Yesterday, my December option premium selling portfolio delta reached close to -60, a level that I have not experienced before. Although I was not terribly uncomfortable with the value, this market typically don't skyrocket high rapidly and there are about 15 days to expiration, I still felt I had to do some risk management to my portfolio to avoid the unlikely but possible damaging event. So I bought 200 shares of SPY to reduce my delta by 200. I also got rid of a hedging calendar of RUT $740c to reduce the delta by another 10. This resulted a total reduction of delta by 30 approximately and a theta increase by a few dollars since the RUT calendar had negative theta.
