NASDAQ:EVOK 4 November 2025

April 12, 2026, 4:08 AM EDT. Greggs (LSE:GRG) shares have tumbled, sparking heavy short interest at 13.8%, equivalent to about £219 million wagered against the stock, according to Research Tree. The FTSE 250 bakery chain faces growth challenges as it nears UK market saturation, limiting new store openings and relying on weak like-for-like sales amid subdued consumer spending. Rising energy and staff costs are pressuring profit margins, contributing to the share price decline. Despite these headwinds, Greggs' solid customer value proposition and cost efficiency maintain long-term appeal. However, its current price-to-earnings (P/E) ratio of 13.5 reflects caution, leaving room for further downside if earnings fail to improve. Investors are weighing these factors amid volatile market sentiment and potential short-squeeze scenarios.
