Okta and Other Companies Set for Major Index Changes in November 2026

Major Changes to Key Stock Indices

In a significant financial development, S&P Dow Jones Indices has announced that several key changes will be made to its major indices, including the S&P 500, S&P MidCap 400, and S&P SmallCap 600. These adjustments will take effect prior to the market opening on November 4, 2026, and they involve the inclusion and exclusion of notable companies in the stock market landscape.

One of the biggest shifts is the addition of Okta Inc. (NASDAQ: OKTA) to the S&P 500, a prestigious index that highlights large-cap companies and their performance. Okta, a leading identity and access management company, will take the spot of Kenvue Inc. (NYSE: KVUE), a move prompted by Kenvue’s upcoming acquisition by Kimberly-Clark (NASDAQ: KMB). This acquisition is anticipated to close shortly, further reshaping the index’s composition.

Impact on S&P MidCap 400

With Okta moving to the S&P 500, the S&P MidCap 400 will see Glaukos Corp. (NYSE: GKOS) stepping in as Okta’s replacement. Glaukos, known for its innovations in glaucoma treatment and eye care technologies, adds valuable health care expertise to the mid-cap index. This change represents a dynamic shift in the health sector representation within the MidCap index.

Changes in S&P SmallCap 600

Meanwhile, the changes extend to the S&P SmallCap 600, where McGrath RentCorp (NASDAQ: MGRC) will replace Glaukos. McGrath, which specializes in rental equipment and providing temporary space solutions, brings an industrial focus to the index. Additionally, Loar Holdings Inc. (NYSE: LOAR) will replace LiveRamp Holdings Inc. (NYSE: RAMP) in the SmallCap index, following LiveRamp’s forthcoming acquisition by Publicis Groupe (Euronext Paris: PUB). This marks another significant reconfiguration of the SmallCap landscape.

What These Changes Mean

The movement of Okta into the S&P 500 is particularly noteworthy. Being part of this index can have substantial implications for a company’s visibility and credibility, often leading to increased investment and market interest. Index funds and ETFs are major players in the market, and inclusion in the S&P 500 may attract significant fund inflows.

When considering the overall health of the indices, these changes reflect current market trends, particularly the strong performance of technology and health care companies. Additionally, the acquisitions underscore a trend of consolidation in various industries, where larger companies are absorbing smaller ones to enhance their portfolios and market reach.

Conclusion

As these changes take effect, investors and market analysts will be closely watching the reactions from both the companies involved and the broader market. The S&P Dow Jones Indices plays a crucial role in guiding investment strategies and assessing market performance. With Okta's addition to the S&P 500 and the other shifts, this November marks a new chapter for these companies and the indices they will soon call home.
