http://www.bloomberg.com/news/2011-08-10/turkey-scrutinizes-short-sales-amid-rout-after-bans-in-greece-south-korea.htmlTurkey moved to curb short sales and threatened “severe penalties” for stock manipulation, joining nations from Greece to South Korea in trying to stem bearish bets after the worst tumble in global shares since 2008.
The minimum cash or equity required to initiate a short sale on the Istanbul Stock Exchange was raised to 70 percent from 50 percent, according to an e-mailed statement from Turkey’s Capital Markets Board today. In a short sale, an investor borrows a security and sells it, expecting to profit from a decline by repurchasing it later at a lower price.
Turkish regulators are investigating whether short sellers manipulated share prices after the ISE National 100 Index tumbled 19 percent this month. South Korea began a three-month ban on short sales yesterday, while Greece started a two-month prohibition on Aug. 9. Italy increased disclosure rules for short sales in July.
The curbs in Turkey are “basically a confidence move to reduce the volatility, particularly in times like these,” Omer Omerbas, head of research at Ekspres Invest, an Istanbul-based brokerage, said in a phone interview today.
