According to TDn2K’s latest Black Box report, the restaurant industry recorded it best quarter in three years in the third quarter. Although comps traffic has slowed in the last few months, robust sales have been driving the restaurant industry through this period. In 2017, the restaurant industry suffered in the third quarter after hurricanes hit Florida and Texas.This year too, Hurricane Florence in the Carolinas somewhat hit restaurant spending in the third quarter. Moreover, rapidly rising interest rates have also resulted in diners cautiously spending at restaurants. Nonetheless, the restaurant industry seems to be on steady growth track with comps registering four straight months of positive year-over-year gains. Given this scenario it makes restaurant stocks must haves for your portfolio. Restaurant Spending Weigh on Retail SalesPer the Commerce Department, retail sales slowed in September as people spent less at restaurants, bars and department stores. This comes despite a flourishing economy, higher wages and robust consumer spending. That said, the restaurant industry has been facing a lull in traffic for some time. Moreover, concerns of rising interest rates have made diners spend cautiously at restaurants.This definitely has been affecting the industry. Moreover, much like in 2017, the impact of Hurricane Florence too somewhat affected restaurant sales last month. Understandably, these factors have weighed on the restaurant industry in September. However, the impressive sales figures in the third quarter definitely indicate that the restaurant industry is bouncing back and is on steady growth track.Restaurant Sales Hit Three-Year High in Third QuarterDeclining traffic has been a growing concern for the restaurant industry for some time now. Even then, the restaurant industry recorded its best quarter in three years, per TDn2K’s latest Black Box report. Same-store sales grew 1.2% in the third quarter, the best since the July-September period in 2015. Since the fourth quarter of 2015, the restaurant industry has not witnessed a quarter wherein all the three months had positive sales.In September, comps grew 1.2%, marking the fourth straight month of year-over-year gains. Sales growth was spread out across the United States, with all the regions posting improvement during both September and the third quarter. Last year, sales were affected particularly in Florida, with hurricanes playing spoilsport. However, measured against last year, Florida recorded the best year-over-year performance with 5.4% compass and 4.31% traffic.Also, job growth among chain restaurants is on the rise, up 2% year over year in August compared with 1.7% in July. Per the report, turnover for both hourly employees and restaurant managers declined in August. After escalating for years, turnover rates have finally started dropping in recent months. Understandably, the restaurant industry has started showing signs of bouncing back and is poised for growth in the coming days.Our ChoicesA lull in traffic has raised concerns over the growth of the restaurant industry.
