Cemex has pulled back after a big run, and the bulls are noticing.
OptionMonster's tracking systems detected the purchase of 6,800 October 10 calls for $1.24. Volume was almost twice previous open interest at the strike, indicating that new money was put to work.
These calls lock in the price where shares can be purchased in the Mexican cement giant, letting investors cheaply control a move to the upside. The contracts can also be used to leverage a rally. For instance, a 26 percent move in the stock would more than double the value of the contracts.
