Nike just reported disappointing China sales figures, and that's exactly when analyst Kevin McCarthy sees an opportunity. 'I'd be a buyer on a day like today,' he says. When a major brand faces short-term headwinds in a key market, it often creates a buying window for contrarian investors. The question becomes whether this is just noise or a sign of deeper weakness. Either way, weakness in China sales—especially for a global consumer brand—shouldn't be ignored. It's a signal worth paying attention to when making decisions about market entries and portfolio positioning.
