The war in Ukraine has roiled the financial markets, especially the currency and energy markets.  Investors have been flocking to precious metals in recent weeks to hedge against global uncertainty.  With gold becoming expensive in a hurry, some investors have been flocking to silver as a substitute. One of the more popular methods of buying silver is through the iShares Silver Trust (SLV).  One large trade from last week in SLV was an 8500 block of out-of-the-money covered calls that expire in May.
