BJ’s Wholesale Club stock will be added to the S&P MidCap 400 on Nov. 5.
The index is a distinct benchmark for mid-sized companies. Westborough-based BJ’s will replace Covetrus Inc., a Maine animal-health technology and services company that will be moved to the S&P SmallCap 600, which more accurately reflects the company’s market capitalization, according to a release from the S&P Dow Jones Indices. BJ’s went public in June 2018 after about four years as a private company under Leonard Green & Partners.
The announcement prompted BJ’s stock to leap by over 6% in early trading on Thursday.
