Dec. 7 (Bloomberg) -- Foreign investors’ holdings in companies listed on the Greek stock exchange were little changed last month from a year earlier, according to data released by Hellenic Exchanges SA, the operator of the Athens bourse.

Non-resident investors held 49.1 percent of the market value of all stocks listed on the Athens Stock Exchange in November, compared with 50.4 percent in November 2010. In October, foreign investors owned 51.4 percent.

Greece’s benchmark ASE share index lost 15.6 percent in November, after former Prime Minister George Papandreou said on Oct. 31 he planned a referendum on the terms of a second bailout, roiling markets and placing Greece’s commitment to the euro in question.

Foreign investors accounted for 41.6 percent of total turnover in November, according to today’s statement.
