"For the 13th time in 14 years, option trading volume grew in 2005 at a record pace, and it's beginning to exhaust superlatives and test the thesaurus. More than 1.5 billion options traded in the U.S., a 27% jump from 2004. These included nearly 1.37 billion stock options (up 26%), and about 135 million index options (up 38%), according to the Options Clearing Corp. The 10 busiest trading days in history? They all occurred in 2005."
