The past few days have been all about records at CBOE. There was record SPX volume and record VIX option volume in January. Just when I thought we had all the records covered VIX option volume topped two million contracts changing hands today. It looks like the exact number is 2,382,752 contracts which beat the old record, set on October 8th last year by just over 600,000. I am not one to use headline type phrases, but today’s volume shattered the old record. Now here is the mind boggling number, VIX call volume was 1,850,206 and put volume was 532,546. The call volume alone would have set a record even if a single put never traded. The table below shows the top five volume days for VIX option trading. Note that three of the top five occurred in 2014.
