Trading volumes in both derivative securities such as futures and options, as well as basic stocks, were more than 20 percent below year-ago levels in May for NYSE Euronext.
The biggest plunge: Trading in U.S. stocks, which dropped 45.5 percent from May 2010 levels, according to the operator of the New York Stock Exchange
The culprit in all cases: Comparison to … May 2010, when volumes were inflated by the sudden drop and resurgence in trading across futures, equities and other markets by the Flash Crash of May 6.
For May 2011, NYSE Euronext said its average daily volume of derivatives contracts, in all markets worldwide, was 10.6 million contracts. This was down 20.6 percent from a year ago.
The exchange operator attributed that to last year when there was “unseasonally strong trading volumes due to heightened market volatility driven by the sovereign debt crisis in Europe.
The emergent debt crisis in Greece helped stoke fears on May 6, when stocks plunged nearly 1,000 points at the worst point. The joint Securities Exchange Commission and Commodity Futures Trading Commission report on that day’s events noted that there was a “ nearly ten-fold increase in volume that occurred as prices in many securities rapidly declined.’’
Which is one backdrop to the NYSE’s report that European stock trading volume in May of this year was 22.0 percent below last year, but that trading in stocks in the U.S. this year was 45.5 percent below May of 2010.
Trading volumes in stocks in U.S. markets stayed at elevated levels for weeks after the May 6 Flash Crash.
