ION Geophysical seldom trades a lot of options, but yesterday it lit up with bullish call buying.
OptionMonster's real-time tracking systems detected the sudden purchase of almost 3,700 November 8 calls for $0.25 against open interest of 1,121 contracts. Those calls lock in an investor's buying price on the stock and stand to appreciate much more rapidly than the shares on a percentage basis if a rally takes place.
The company provides seismic-imaging to drillers in the energy sector. It plunged hard in early August after earnings missed estimates but has been bouncing in a range since then.
Based on yesterday's call buying, a large trader expects ION to make a nice run in the next four weeks. The timing of the next earnings report hasn't been announced yet, but it should take place before the option expiration on Nov. 18.
The stock rose 5.98 percent to $7.09 in the session. It normally trades fewer than 500 contracts a day, so the activity in those November 8s was clearly unusual.
