Vertiv, Lumentum and EchoStar recorded intraday gains after S&P Dow Jones Indices announced their inclusion in the S&P 500, with Coherent also named to join. The additions take effect before the open on March 23 as part of the quarterly reconstitution, which will push four other companies into the S&P SmallCap 600 and alter the S&P 100 membership.

Key Points

  • Vertiv (VRT), Lumentum (LITE), EchoStar (SATS) and Coherent (COHR) will join the S&P 500 before the open on March 23 as part of the quarterly rebalance.
  • Match Group (MTCH), Molina Healthcare (MOH), Lamb Weston Holdings (LW) and Paycom Software (PAYC) will move to the S&P SmallCap 600 as replacements.
  • S&P 100 membership will also change: Micron (MU), Lam Research (LRCX), Applied Materials (AMAT) and GE Vernova (GEV) will join; PayPal (PYPL), AIG (AIG), MetLife (MET) and Target (TGT) will exit.

Shares of Vertiv Holdings (NYSE:VRT) rose 3% on Monday, while Lumentum Holdings (NASDAQ:LITE) gained 2% and EchoStar (NASDAQ:SATS) climbed 1.3% after S&P Dow Jones Indices revealed late Friday that the companies will be added to the S&P 500. Coherent (NYSE:COHR) was also named among the entrants.

The index provider said the four companies will join the benchmark before trading opens on March 23 as part of the routine quarterly rebalance. The adjustments are intended to keep each index reflective of its market-capitalization range.

Replacements and classifications

  • The incoming S&P 500 constituents will replace Match Group (NASDAQ:MTCH), Molina Healthcare (NYSE:MOH), Lamb Weston Holdings (NYSE:LW) and Paycom Software (NYSE:PAYC). Those four companies are slated to move to the S&P SmallCap 600.
  • Vertiv is classified within the industrials sector. Lumentum and Coherent are identified as information technology companies. EchoStar is categorized under communication services.

S&P 100 adjustments

  • The quarterly rebalance also updates the S&P 100. Micron Technology (NASDAQ:MU), Lam Research (NASDAQ:LRCX), Applied Materials (NASDAQ:AMAT) and GE Vernova (NYSE:GEV) will join that index.
  • Exiting the S&P 100 will be PayPal Holdings (NASDAQ:PYPL), American International Group (NYSE:AIG), MetLife (NYSE:MET) and Target (NYSE:TGT).

Index inclusion commonly triggers additional buying by funds that track the benchmark, since index-tracking mutual funds and exchange-traded funds typically acquire shares to mirror index composition. The announcement came after the market close on Friday, with the initial share-price responses for several named companies visible on Monday.

Context and limitations

The changes described reflect a routine reconstitution process carried out by S&P Dow Jones Indices. The article reports the specific companies named for addition and removal, their effective date, and the immediate market reaction for three of the named stocks. It does not provide forecasts, estimates of net flows, or further detail on the magnitude or duration of buying by index funds, and no future performance claims are made.

Risks

  • While inclusion typically leads to increased demand from index funds and ETFs, the article does not quantify the size, timing, or persistence of such flows - market impact is therefore uncertain.
  • The article reports short-term share-price movements for three companies following the announcement, but it does not provide information on longer-term performance or whether those gains will continue.
  • Reconstitution alters index composition, which can create redistribution of passive fund flows; the article does not specify how individual sectors beyond those classified for incoming companies may be affected.
