<li>The SP 500 index tracks the 500 largest (mostly profitable) US-listed names and is one of the most highly-tracked indices in the world.</li>
<li>A spin-off completes next week, and the new company's entry into the SP 500 is expected to trigger an intra-review deletion.</li>
<li>We expect two ADDs and two DELs at the December 2026 rebalance, and two M&amp;A deals could trigger intra-review ADDs before that.</li>

A spin-off completes next week, and the new company's entry into the SP 500 is expected to trigger an intra-review deletion.
We expect two ADDs and two DELs at the December 2026 rebalance, and two M&amp;A deals could trigger intra-review ADDs before that.
