How different types of restaurants behaved differently through the recent recession an analysis of stock market and financial ratios

Abstract

<p>This study attempted to identify, quantify, and explain the possible impact the recession had on restaurant stock performance in comparison with the S&P 500 index using ARIMA with Intervention analysis approach and t-tests. Based on the North American Industry Classification System, limited-service (NAICS code 722211) and full-service restaurant segments (NAICS code722110) were examined. The results of this study suggest that the limited-service restaurant segment was recession-proof and outperformed both the full-service restaurant segment and the S&P 500 index. The findings of this study will not only provide the industry with empirical evidence of restaurant performance during and after the recession; but also fill the gap of literature by applying ARIMA with Intervention Analysis in identifying the lag time of impact an event has on time series.</p>
