周二盘中，美国快餐连锁巨头温蒂汉堡（WEN）股价出现大幅下跌，跌幅高达5.03%。虽然公司本身未发布任何重大消息，但行业内的一则新闻可能对其股价造成了影响。
据报道，温蒂汉堡的主要竞争对手汉堡王正面临一项集体诉讼。该诉讼指控汉堡王在广告中误导消费者，夸大其招牌产品Whopper三明治和其他菜品的尺寸。美国迈阿密地区法官罗伊·奥特曼裁定，这项诉讼可以继续进行，理由是"一些"合理的消费者可能会被汉堡王的广告所欺骗。
尽管这起诉讼直接针对的是汉堡王，但它可能引发投资者对整个快餐行业的担忧。如果诉讼成功，可能会影响快餐行业的广告策略，并可能损害消费者对快餐品牌的信任。作为行业内的主要竞争者之一，温蒂汉堡的股价可能受到这一消息的连带影响。投资者可能担心类似的诉讼风险也会影响到温蒂汉堡，或者整个行业的广告效果可能会受到影响，从而导致销售额下降。
