With energy markets being highly volatile this year, it’s not a surprise to see large block trades occur in big energy companies.  Oil and gas giant, Exxon Mobil (XOM), tends to have plenty of options volume on a regular basis. However, on a busy day last week, it traded nearly twice the amount of average daily options contracts. The biggest block trade of the day was a 4-month covered call trade collecting over 4% in premiums.
