Shake Shack (NYSE:SHAK) shares outpaced the market by a wide margin last month as the stock gained 33% compared to a 2% decrease in the S&P 500, according to data provided by S&P Global Market Intelligence.
The rally pushed the "better burger" specialist to more than a 100% return so far in 2019.
Investors in consumer goods celebrated news from the company that showed building operating momentum. Shake Shack achieved head-turning sales growth as it added 11 new locations to its relatively small footprint. But the better news was that revenue is in solidly positive territory at existing restaurants, too, which marks an improvement over the 2018 fiscal year.
CEO Randy Garutti and his team were encouraged enough by the latest growth trends that they lifted their outlook for the year. They now see comparable-store sales rising by a firm 2% rather than the 1% to 2% uptick they had predicted. While that would still trail industry leader McDonald's (NYSE:MCD) by a wide margin, the customer traffic gains are supporting an even faster expansion pace for Shake Shack, which now plans to open around 39 new stores to represent a roughly 50% increase year over year.
