UPDATE: Regulators Bans some short selling in Belgium, France, Italy and Spain. From European Securities and Markets Authority: ESMA promotes harmonised regulatory action on short-selling in the EU

• From the NY Times: Europe Considers Ban on Short-Selling

The European Securities and Markets Authority, a body that coordinates the European Union’s market policies, has been requesting information from member states about ... short-sales ... “We are discussing with national authorities and together we will decide whether we need coordinated action,” Victoria Powell, a spokeswoman for the authority, said Thursday.

Banning short sales always looks like desperation.

• From MarketWatch: Second-quarter GDP view cut after trade data. With the higher than expected trade deficit in June it looks like Q2 real GDP growth might have been below 1% for the 2nd straight quarter. The 2nd estimate of Q2 GDP will be released on August 26th.

• From MasterCard: Total U.S. Retail Sales for July Up 8.7% Year-over-Year

Excluding auto sales retail sales grew by 8.7% year-over-year. Retail sales are on par with the average growth of the previous 3 months, and have held onto their momentum despite concerns from other areas of the economy.

Michael McNamara, VP of Research and Analysis for MasterCard Advisors SpendingPulse, noted: “Since March, non seasonally-adjusted retail sales have topped 8% year-over-year. However, much of the 8.7 percent growth is from commodity based inflation in areas such as gasoline, food and cotton prices. While the headline year-over-year increase resembles periods of strong economic growth, when you take a closer look at the comp environment and the year-over-year inflation, it tempers the enthusiasm that would normally accompany this level of year-over-year increase.”

Retail sales for July will be released tomorrow.
