Signet Jewelers' shares have climbed nearly 20% in the past month, according to Benzinga. The rally is helped by pop culture momentum from Taylor Swift’s engagement to Travis Kelce and strong second-quarter earnings. CEO J.K. Symancyk told CNBC’s Jim Cramer that Swift’s engagement fueled a surge in consumer interest for cushion-cut diamond rings, lifting Signet’s stock more than 3% immediately after the news. The company posted adjusted EPS of $1.61 on revenue of $1.53 billion, up 3% year-over-year and ahead of Wall Street expectations. Same-store sales across its brands, including Kay, Zales, and Jared, rose 5% in the quarter. Telsey Advisory Group noted progress under Symancyk’s leadership, citing sales, gross margin, and SG&A beats, while maintaining a Market Perform rating and $92 price target. Shares traded 1.29% lower at $89.29 on Wednesday.
