Alliance Capital Management is among about 20 companies under investigation by the New York Stock Exchange for improperly identifying short-sale stock transactions, the asset manager said in its quarterly report to the Securities and Exchange Commission.

According to an Aug. 5 report from the Associated Press, the company's institutional trading and research unit, Sanford C. Bernstein, received a Wells notice from the NYSE. A Wells notice is typically a precursor to a civil suit from the Big Board.

Short sales are a chief concern among regulators, because they could be used to artificially drive down a stock price, the AP report notes. Alliance Capital said it traced the error to a technical snafu that was fixed two years ago.

Alliance Capital also reported that the Bernstein unit received a separate Wells notice form the NASD, because one of its trading analysts allegedly sold shares in companies they had announced a suspension of coverage upon.
