A Record-Breaking Week

August 12, 2011

What a week. The S&P 500 had the biggest slump since November 2008. U.S. stocks tumbled. The Dow Jones Industrial Average, NASDAQ Composite, and Russell 2000 – – all tumultuous.

This point in time is certainly disconcerting for people, especially business and financial professionals. Since Bloomberg has many lenses into the moving markets through our data, news, and analytic tools, we wanted to take this opportunity to share with you some of what we are seeing.

The recent market turmoil broke historic highs for market data activity globally, according to Bloomberg’s Research & Development team. Bloomberg processed 43.7 billion ticks on August 10, 2011 (a tick is an upward or downward movement in a security’s trades, bids, and offers prices; tick data provides all market activity, not only volume of shares traded, giving investors full market transparency to make more informed trading decisions). This is 46 percent higher than previous days, including peaks in volatility experienced during the Japanese earthquake, the flash crash, and the apex of the financial crisis.

Market tick volume reaches historic highs had some of its biggest traffic days ever, with more than 60 percent increases over average daily unique visitors and page views. The live TV player on had nearly three times the amount of unique visitors than what we see on average per day. And, we were the first in reporting the announcement of S&P’s downgrade of the U.S.’s credit rating on the Bloomberg Professional service.
