Silver miner Coeur d'Alene Mines has been building support, and yesterday the bulls stepped in with a long-term trade.
OptionMonster's tracking systems detected the purchase of about 3,500 January calls, most of which priced for $1.30. Volume was 14 times open interest at the strike.
Calls lock in the price where investors can buy shares, so they can generate nice leverage in the event of a rally. But they will expire worthless if the stock doesn't move.
CDE shares rose 1.26 percent to $24.10 yesterday. This means that those calls are way out of the money, so the stock needs to make a substantial move in the next year for the trade to pay off.
The stock has bounced several times at its 200-day moving average around $22. The average was also a key level in late August, so some chart watchers may want to get long around that price.
In addition, CDE shares climbed last Thursday, even though the price of silver tumbled almost 4 percent. Such price action suggests that buyers are targeting the shares.
Total option volume was 5 times greater than average yesterday, with calls outnumbering puts by a bullish 8-to-1 ratio.
