What Happened On December 21, 2020, Tesla TSLA officially joined the S&P 500 index, marking a pivotal moment in the company's history and a significant event for the broader market. The inclusion followed months of anticipation and speculation, which had already fueled a substantial runup in Tesla's stock price. The announcement itself, made in midNovember, triggered a surge, as index funds and active managers were forced to buy billions of dollars worth of TSLA shares to rebalance their portfolios and track the index. This unprecedented demand created a unique trading environment as the actual inclusion date approached. On the day of inclusion, December 21st, 2020, Tesla's stock experienced considerable volatility. The stock saw a flurry of activity as institutional investors completed their portfolio adjustments, leading to massive trading volumes. While there was some expectation of a "sell the news" event, where the stock might retreat after the inclusion, the overall sentiment remained strong, driven by Tesla's growth prospects and its growing influence in the automotive and technology sectors. The day was characterized by intense trading, reflecting the magnitude of the rebalancing act required for such a large and impactful company to enter the benchmark index.
