Key Points

  • Toast, IES Holdings and National Health Investors were named to S&P indices and saw premarket gains after the index changes were announced - impacting midcap and smallcap stocks.
  • TopBuild and Janus Henderson are being replaced in the S&P MidCap 400 amid pending acquisitions, while Apollo Commercial Real Estate Finance is being removed from the S&P SmallCap 600 amid liquidation activity.
  • Honeywell Aerospace will be added to the S&P 500 and S&P 100; Conagra Brands will move into the S&P SmallCap 600 to replace Grid Dynamics, reflecting broader index rebalancing across market-cap tiers.

Stocks of Toast Inc. (NYSE:TOST), IES Holdings Inc. (NASDAQ:IESC) and National Health Investors Inc. (NYSE:NHI) showed premarket strength on Wednesday, with each name rising following an announcement by S&P Dow Jones Indices that reshuffled constituents in its midcap and smallcap indexes.

Index additions and effective dates

Toast will be added to the S&P MidCap 400, taking the place of TopBuild Corp. (NYSE:BLD), with the change effective prior to the opening of trading on Wednesday, July 1. The announcement notes that QXO Inc. (NYSE:QXO) is acquiring TopBuild in a transaction expected to close soon, subject to final closing conditions.

IES Holdings is also slated for inclusion in the S&P MidCap 400, replacing Janus Henderson Group plc. (NYSE:JHG). That change is scheduled to take effect prior to the opening of trading on Wednesday, July 1. The filing states that Trian Fund Management LP and General Catalyst Group Management are acquiring Janus Henderson Group in a deal expected to close soon, pending final closing conditions.

On the small-cap side, National Health Investors will enter the S&P SmallCap 600, replacing Apollo Commercial Real Estate Finance Inc. (NYSE:ARI) effective prior to the opening of trading on Tuesday, June 30. The committee said Apollo Commercial Real Estate Finance has announced ongoing liquidation activities and is no longer appropriate for the S&P SmallCap 600.

Additional S&P adjustments

S&P Dow Jones Indices also confirmed that Honeywell Aerospace Inc. (NASDAQ:HONA) will be added to both the S&P 500 and the S&P 100 on Monday, June 29. Honeywell Aerospace will replace Conagra Brands Inc. (NYSE:CAG) in the S&P 500, and Conagra Brands will move into the S&P SmallCap 600 to replace Grid Dynamics Holdings Inc. (NASDAQ:GDYN) - with the Conagra-to-SmallCap change effective prior to the opening of trading on Tuesday, June 30.

Market implications

Inclusion in S&P indexes typically results in incremental buying pressure from index funds and exchange-traded funds that track those benchmarks, which can affect trading volumes and short-term demand for the securities being added.

Risks

  • Pending acquisitions - The replacements for TopBuild and Janus Henderson are tied to deals that are "expected to close soon, pending final closing conditions," creating uncertainty for those companies and potential volatility in related stocks - this affects the industrials and financial sectors.
  • Liquidation and eligibility - Apollo Commercial Real Estate Finance's announced liquidation activities led to its removal from the S&P SmallCap 600; ongoing liquidation introduces uncertainty for holders of the company's securities and impacts the real estate finance sector.
  • Index-driven demand - While inclusion often brings buying from index-tracking funds, the timing and magnitude of that demand can vary, potentially causing short-term price swings for newly added midcap and smallcap names.
