How does a company get added to the S&P 500?

To join the index a company must be U.S.-domiciled, carry a float-adjusted market cap above the current minimum threshold (revised periodically by the index committee), report positive as-reported earnings in its most recent quarter and over the trailing four quarters combined, satisfy minimum liquidity requirements, and have been publicly traded for at least 12 months. The final selection is made by a committee — meeting the quantitative criteria is necessary but not automatically sufficient.

What happens to a stock's price when it's added to the S&P 500?

Historically, newly announced additions often saw an immediate price pop as index funds raced to buy shares before the effective date — a dynamic called the "index effect." Academic research shows this premium has narrowed significantly over the past two decades as arbitrage capital learned to anticipate index rebalances in advance. High-profile additions can still move 5–10% on announcement, but on average across all additions the effect is now close to zero. Investors should weigh this carefully rather than treating index inclusion as a reliable catalyst.

When is the next S&P 500 rebalance?

The index is reconstituted on a quarterly schedule — changes typically take effect on the third Friday of March, June, September, and December. Announcements usually come one to two weeks before the effective date. Between scheduled rebalances, unplanned changes occur whenever a constituent is acquired, delisted, or no longer meets the eligibility criteria.

Why was a company removed from the S&P 500?

Removals happen for several reasons: the most common is an acquisition (the acquired company's shares cease to exist independently), followed by a sustained drop in market cap well below the minimum threshold, failure to meet profitability requirements, or a delisting from a major exchange. Spin-offs can also trigger off-cycle changes if the newly created entity or the parent company no longer qualifies.
