Three companies, CRH Plc, Carvana Co., and Comfort Systems USA Inc., are set to join the S&P 500 index as part of a quarterly rebalancing scheduled for the end of December. According to S&P Dow Jones Indices, these firms will replace LKQ Corp., Solstice Advanced Materials Inc., and Mohawk Industries Inc. before trading begins on December 22.
Following the announcement, shares of Carvana, a used car retailer, and CRH, a building materials company, surged by more than 7% during post-market trading. Comfort Systems, which specializes in heating and ventilation solutions, saw an increase of about 2%.
Carvana, based in Tempe, Arizona, has experienced remarkable growth, with its stock price soaring from a low of under $4 in 2022 to approximately $400 at present—a staggering gain of 10,000%. This significant rise in value can be attributed to the company’s successful efforts to reduce costs and restructure its debt, leading to improved earnings. Notably, Carvana reported selling a record 156,000 vehicles in the most recent quarter.
The inclusion of companies in the S&P 500 has become increasingly crucial amid the rise of passive investing. As more index-tracking funds align their portfolios with the S&P 500, demand for shares from newly included companies typically increases. To qualify for the S&P 500, firms must maintain a market capitalization of at least $22.7 billion and meet specific profitability, liquidity, and share-float requirements.
However, being removed from the index can negatively impact stock prices, kicking off a selling wave by index funds that need to adjust their holdings. Analysts from Bloomberg Intelligence had previously identified Carvana, CRH, and Comfort Systems as strong contenders for inclusion, highlighting Carvana’s alignment with diversity criteria and substantial stock gains of nearly 100% this year.
While the excitement generated by inclusion announcements often leads to brief stock price spikes, some market strategists caution that this demand typically diminishes quickly once a stock officially enters the index. Despite this, the relevance of such announcements continues to grow in a market increasingly dominated by index-tracking investment strategies.
