NYSE adds 30 stocks to SEC's short sale ban
WASHINGTON (Reuters) - The New York Stock Exchange has added 30 stocks of companies that engage in financial services to a temporary ban on short selling ordered last week by U.S. regulators.
The NYSE list, issued on Monday, includes shares of General Electric , M&T Bank Corp , Legg Mason and General Motors Corp .
The U.S. Securities and Exchange Commission, besieged by complaints that its list of 799 stocks issued on Friday had missed companies with major financial operations, decided over the weekend to let exchanges add to its list.
The SEC emergency order against short sales in financial stocks will last through October 2. It may be extended further if the agency deems it necessary, but it can only last a total of 30 calendar days.
The SEC order followed similar action by the U.K. Financial Services Authority, which imposed a temporary four-month ban on short-selling of financial stocks.
Other companies on the NYSE list include Capital One Financial Corp , Discover Financial Services and U.S.-traded shares of several Canadian banks including Toronto Dominion Bank .
