Honeywell Aerospace Replaces Conagra in S&P 500 Index

Standard & Poor's announced on 24 June 2026 that Honeywell Aerospace will replace Conagra Brands in the S&P 500 index. The change is effective at the close of trading on the same day. Honeywell Aerospace's stock traded at $222.37 as of 05:03 UTC today, a decline of 2.90% on the session. The broader S&P 500 index has returned over 8% year-to-date, highlighting the selective growth sparking index changes. This reshuffle shifts billions in passive capital between the industrial and consumer staples sectors.

Context — [why this matters now]

Momentum in aerospace and defense stocks has outperformed the broader consumer packaged goods sector throughout 2026. The S&P 500 Aerospace & Defense sub-industry index has gained 18% year-to-date, while the S&P 500 Food Products index has lagged with a 3% return. This performance divergence is a primary driver behind index committee decisions to maintain the S&P 500's representation of the largest and most relevant U.S. companies. The last major industrial-for-consumer swap occurred in September 2025 when a robotics firm replaced a declining retailer. Index changes are typically triggered by corporate actions like spinoffs or significant shifts in a company's market capitalization and sector representation. Conagra's spin-off of its frozen meals division in late 2025 reduced its overall market footprint, creating an opening for a high-growth industrial segment.

Data — [what the numbers show]

Honeywell Aerospace's market capitalization now exceeds $150 billion, qualifying it for immediate inclusion in the large-cap benchmark. Conagra Brands' market cap has contracted to approximately $18 billion following its corporate restructuring. The price move for HON on the announcement day was within its typical daily range of $220.64 to $225.78. Passive funds tracking the S&P 500 collectively manage an estimated $13.5 trillion in assets. These funds will be forced to sell roughly $18 billion worth of Conagra shares and purchase an equivalent dollar amount of Honeywell Aerospace stock to realign their portfolios. This mandated trading represents a significant liquidity event for both securities. The reshuffle also triggers adjustments in numerous sector-specific and smart-beta ETFs that use the S&P 500 as a construction universe.

Analysis — [what it means for markets / sectors / tickers]

The immediate second-order effect is a direct capital inflow of approximately $18 billion into Honeywell Aerospace shares from index funds. Outflows of the same magnitude will hit Conagra Brands. This mechanical flow provides a structural bid for HON and a headwind for CAG around the rebalancing date. Industrial sector ETFs and mutual funds may see increased interest as the S&P 500's weighting toward industrials grows marginally. Aerospace peers like Raytheon and Lockheed Martin could see sympathetic buying as sector-focused funds rebalance to account for HON's increased prominence. A key counter-argument is that the market impact is often front-run by arbitrageurs, diminishing the price effect on the official rebalancing day. Hedge funds and proprietary trading desks frequently establish positions weeks in advance to profit from the predictable fund flows, which can mute the final move. Current positioning data shows elevated short interest in consumer staples ETFs and increased call option volume on major industrials.

Outlook — [what to watch next]

The next scheduled quarterly S&P 500 rebalancing is set for after the close on 18 September 2026. Market participants will monitor the earnings results for both Honeywell Aerospace on 24 July and Conagra Brands on 13 August for post-reshuffle performance guidance. A key level to watch for HON is the $225.78 daily high from today's session; a sustained break above could signal continued momentum. For CAG, support will be tested by the forced selling from index funds, and its price action relative to the consumer staples sector will be telling. If the Federal Reserve's policy stance shifts at the July FOMC meeting, it could alter the growth outlook for industrials versus defensive staples, influencing the long-term success of this index change. The reshuffle's final volume will be reported by major exchanges after market close on 24 June.

Frequently Asked Questions

What does an S&P 500 reshuffle mean for retail investors?

Retail investors holding index funds or ETFs that track the S&P 500 will automatically have their Conagra Brands shares sold and replaced with Honeywell Aerospace shares, with no action required. The transaction occurs at the closing prices on the effective date. For direct stock owners, the forced selling from index funds can create temporary price pressure on the removed stock and buying support for the added stock around the rebalance date.

How does this change compare to other recent S&P 500 additions?

This reshuffle follows the pattern of recent years where high-growth technology or industrial companies replace slower-growth consumer or energy firms. It is similar in magnitude to the September 2025 change where a automation company replaced a department store chain. The $18 billion market cap swing is considered a standard, mid-sized reshuffle, not as large as the mega-cap tech additions seen earlier in the decade.

What is the historical impact on stock performance after index inclusion?

Academic studies show a persistent but small positive effect on a stock's price and liquidity following S&P 500 inclusion, often referred to as the "index effect." This is primarily due to increased institutional ownership and analyst coverage. However, much of this effect is often arbitraged away in the weeks leading up to the official change date, making post-inclusion returns less predictable and more dependent on company fundamentals.

Bottom Line

Niche industrial growth is displacing mature consumer brands at the core of the U.S. equity benchmark.
