Twilio (TWLO) is making history this week. The cloud communications company will join the S&P 500 ($SPX) before the opening bell on Tuesday, Oct. 6, replacing Warner Bros. Discovery (WBD) in the most widely followed benchmark for U.S. stocks.
And it should be a catalyst for Twilio’s stock price. More than a dozen exchange-traded funds and hundreds of conventional index mutual funds follow the S&P 500, so when Twilio comes on board, each will buy Twilio as they adjust their holdings.
