optionMONSTER's tracking systems spotted unusual activity the August 26.50 calls, which traded more than 10,000 times, mostly for $0.84 to $0.89. Those expire at the end of today's session, so traders are obviously looking for the metal to move in a hurry.
Calls lock in the price of buying the exchange-traded fund, which tracks the price of silver. The options can generate some nice leverage if the stock climbs, but they can lose all of their value from just a small decline.
There was plenty of activity in other strikes, like the September 28s, the August 27.50s, and the August 28s.
The SLV rose 1.56 percent to $27.39 yesterday. Calls outpaced puts in the fund by about 4 to 1, reflecting the session's bullish sentiment. Total volume in the name was almost twice its daily average.
