Market Volatility Drives FINRA’s Volume to New Record in 2018

Exceptional market volatility generated an unprecedented amount of processing volume for FINRA in 2018 – 66.7 billion electronic records per day, an 87.4 percent increase over the average daily volume in 2017. FINRA’s pioneering cloud strategy allowed it to handle the record-setting volume smoothly while continuing to perform vigorous regulatory oversight of securities trading.

“The story of 2018 was not just the individual, breakthrough days that set new records – it was also the sustained, high-volume activity that we managed for days and even weeks at a time,” said CIO and Executive Vice President Steve Randich. “Our mission of protecting investors depends on our staying current with the market and continuously monitoring and analyzing for potential suspicious activity. Cloud storage and processing responds instantly to elastic demand, providing our market-surveillance analysts with access to petabytes of data in seconds or minutes, even during periods of uninterrupted record-breaking activity.”

Trading activity in the stock, options and fixed-income markets creates a variety of electronic records that FINRA monitors for regulatory purposes. Every day, FINRA receives order and trade data regarding 42,000 investment products from 17 securities exchanges, more than 60 alternative trading systems and almost 1,400 broker-dealer firms. FINRA runs almost 200 algorithmic “patterns” to look for more than 300 potential threat scenarios including market manipulation, fraud, customer abuse, insider trading, abusive short selling, inaccurate trade reporting, and other rule violations.
