New Trade: Silver ETF (SLV) Naked Puts

Today in a taxable account I entered the following short term transaction:

12/22/2011    STO 8 SLV Dec 30 2011 26 Puts @.09                     55.94

This is an 8 day trade in SLV. SLV would have to drop 8.2% in 8 days for these to be in the money.  If these expire worthless we will earn 2.24% on our maintenance requirement of $2496 which equates to 102.2% annual. We are bullish precious metals and are of the belief that SLV has support at present levels of 28 and change.
