Traders are digging for gold in Jaguar Mining.
The mining company received a $1 billion acquisition offer from China Shandong Gold in November, valuing the company at $9.30 a share and prompting a strategic process to explore alternatives. But Jaguar's CEO resigned in December, and the stock dipped back under $7 after the firm indicated that the review process may not end in a deal.
Option activity has been interesting in the last month and really lit up Friday morning. Traders were buying the June 8 calls for $0.80, while selling the June 10 calls for $0.15. This call spread traded more than 5,000 times.
The position allows traders to buy Jaguar for $8, but obligates them to sell it for $10 if the stock goes above that level. The bet cost $0.65, so they'll earn more than 200 percent if the stock rallies to $10 or higher.
Traders use this type of “vertical spread” — buying calls at the lower strike and selling the higher strike — to offset the cost of establishing the position, though it limits upside potential.
Jaguar rose 1.68 percent to $7.28 on Friday, and is up 15 percent in the last month as buyers return to the gold-mining space in general.
More than 13,000 Jaguar calls traded versus just 1,300 puts in the session, a reflection of the bullish sentiment. Total option volume was nearly 5 times average levels.
