Superior Industries International’s stock rose sharply after Vista Group Ltd. said it would press ahead with efforts to buy the Van Nuys-based maker of wheel rims and other auto accessories. Superior’s common stock closed at $13.625, up $2.125 from Monday in American Stock Exchange composite trading. The shares did not trade Tuesday amid confusion triggered when Vista, a Los Angeles investment firm, announced that it was making a joint bid with Prudential-Bache Securities to buy Superior for $16 a share, or $93 million. Prudential-Bache then denied being involved in the offer. Superior said it was not interested in being acquired in any case.
