A £5,000 investment in Greggs shares just one month ago would now be worth approximately £6,200, representing a striking short-term return for patient investors.
The bakery chain’s shares had struggled for an extended period before experiencing this sharp upward move, raising questions about whether the rally has lasting power.
The catalyst behind the jump was a set of solid first-half 2026 results, published on 29 July, that reassured investors after a prolonged run of disappointing performance.
For the first half of the year, Greggs reported total sales up 7.2% year on year, reaching £1,101.5 million, while like-for-like sales rose 2.1% over the same period.
Profit before tax climbed a notable 19.7% to £76 million, a figure that clearly resonated positively with a market that had grown accustomed to weaker updates from the company.
CEO Roisin Currie noted that “Greggs continued to outperform the market and has delivered an improved sales performance and strong cost control through the first half of 2026, resulting in profitable growth.”
The results were not without limitations, as the company offered no upgrade to its full-year guidance and did not announce any increase to its dividend payment.
However, the rally may have been amplified by short-seller activity, since closing a short position requires buying back borrowed shares, which adds further upward pressure to a rising stock price.
Greggs has been actively building out its grocery retail channel through partnerships with Tesco and Iceland, with that segment described as delivering strong growth at present.
Menu innovation is also playing a role in supporting performance, with the company rolling out products including iced matcha lattes, new salads, and a chicken roll to drive like-for-like sales.
On the valuation front, the stock’s forward price-to-earnings ratio currently sits at around 16, which looks stretched given that no earnings growth is expected this year amid higher capacity investment costs.
A number of headwinds remain in play, including rising costs, the growing influence of GLP-1 weight-loss drugs, squeezed consumer cash flow, and shifting consumer tastes and preferences.
The average analyst 12-month price target for Greggs currently stands at 1,665p, which sits approximately 15% below where the shares are trading today.
Short sellers have not yet exited their positions in meaningful numbers, signalling that bearish investors still expect the stock to give back a portion of its recent gains.
While the breakout from a year-long trading range is technically encouraging, the combination of full valuation, cautious analyst targets, and lingering short interest suggests the investment case remains far from straightforward.
