In today's fast-paced world, consumers are frequently on the lookout for quick and convenient eating options. This assertion, along with benign early fall weather, may help to explain the uptick in September restaurant sales. Restaurant same-store sales increased by 1.2% in the final month of the third quarter, rounding out four months of consecutive growth. Moreover, the third quarter of 2018 was the first time in three years that all regions in the United States have posted positive sales growth.

Despite the positive sales numbers, some industry experts believe that restaurants are likely to see more moderate growth ahead due to a restraint on consumer spending caused by gradual wage growth, higher gas and utility prices, and rising interest rates. Investors who wish to navigate the risk and reward of investing in fast food restaurant stocks should look over these leading names in the space.

McDonald's Corporation (MCD)

With a market capitalization of $140.69 billion, McDonald's is one of the world's largest and most recognized food franchises. The company, headquartered in Chicago, Illinois, operates roughly 37,000 restaurants as of November 2018.

As of Nov. 7, 2018, McDonald's stock has a year-to-date (YTD) return of 6.57% and offers a 2.57% dividend yield.

McDonald's share price broke out of a six-month trading range after the fast food company beat top and bottom line third quarter earnings estimates. The stock has continued with follow-through gains and made a YTD high of $182.86 on Nov. 6. McDonald's share price looks overbought in the short term, with the relative strength index (RSI) giving a reading above 70.
