    S&P 500 additions

    September 7, 2021

    Three companies, Match Group (NASDAQ:MTCH), Ceridian (NYSE:CDAY), and Brown & Brown (NYSE:BRO) are joining the S&P 500, an index containing 500 of the largest US companies.

    • The newly added companies will replace Unum Group (NYSE:UNM), Nov (NYSE:NOV), Perrigo (NYSE:PRGO).

    What’s the big deal? Several funds and ETFs across the world replicate the S&P 500. These funds are required to buy the stocks of companies that join the S&P 500.

    To make it onto the list, companies must meet a couple criteria:

    • Report 4 straight quarters of profit.
    • Have a market capitalization of at least $11.8b.
    • Be listed on the NYSE, Nasdaq or CBOE.

    The company’s stock must also be highly liquid — which makes it easier for investors to buy and sell stock.

    For these reasons, companies on the S&P 500 are often higher quality. For many investors, holding an ETF that replicates the S&P 500 is a safer long-term bet — i.e. iShares Core S&P 500 ETF (NYSE:IVV).

    So being included in the S&P 500 is a good thing for their stocks right? Right?

    Don’t get your hopes up: According to a study of over 500 companies that joined the S&P 500, on average:

    • Between 1997-2007, newly added companies’ stocks jumped 4.9% in the first week after joining the index. That fell to 0.7% between 2007-2017.
    • Between 1997-2017, companies that joined the S&P 500 fell over the next 12 months after being included.

    Which means: S&P 500 inclusion is a poor reason to buy a stock. In most cases, upon the initial announcement, the stocks have already made their moves.
