The Philadelphia Stock Exchange, which has one of the country's biggest options trading floors, said last week it had broken its own volume record. Good thing, because given the market turmoil driving up options trading everywhere, anything but a big increase might look a bit off: On Dec. 20, the PHLX recorded 6.399 million contracts traded, giving it roughly 31.5 percent of options market that day.
The other big options exchanges also have been bustling. The Chicago Board Options Exchange (CBOE) and Intenational Securities Exchange (ISE), both usually bigger than PHLX by volume, also have both declared they broke their own monthly records for November.
