1) I would like to reorganize the historical components section of the page and 2) move it onto it’s own page, while keeping the most recent changes dating back to 2020 on the main page. Rube Dali, the DodoHorse (talk) 17:24, 6 January 2025 (UTC)[reply]

Agree, it would be preferable for this portion to be arranged in the same way as the regular rebalancing of the S&P 500. GrldDB (talk) 14:24, 21 May 2025 (UTC)[reply]

I am currently working on converting the “Yearly Changes” section to tabular format similar to the “S&P 500 Companies” page. Probably once this section is completed, the current components along with the “Yearly Changes” can be migrated to a new page. GrldDB (talk) 13:38, 29 May 2025 (UTC)[reply]

Finished converting the changes. Feel free to move it to a separate article if you prefer. GrldDB (talk) 10:36, 23 June 2025 (UTC)[reply]

In July it was reported that Thomson Reuters would replace ANSYSS, who were acquired by Synopsys. However, the NASDAQ website, which is linked as a reference [1] does not include TRI on August 10. I had removed TRI accordingly, but this was undone. Was this entry changed by NASDAQ or is it a mistake in their list? Wosch21149 (talk) 11:09, 10 August 2025 (UTC)[reply]

Finally Nasdaq corrected it. Now TRI is in their components list. Wosch21149 (talk) 16:03, 31 August 2025 (UTC)[reply]

I have changed the sector and industry classification of NASDAQ-100 component stocks from GICS to ICB. Please note that the methodology document explicitly provides for the ICB classification, not the GICS classification.[2]

This change was necessary especially for Paypal (PYPL) which is classified by GICS as “Financials/Transaction & Payment Processing Services” but by ICB as “Industrials/Diversified Commercial Services” which explained for its inclusion in the Nasdaq-100 index.

I may have to adjust some changes which @Ksu6500 made on the industry classifications. As I emphasized here, NASDAQ itself uses ICB and not GICS in its own methodology sheet for NASDAQ-100 above. Nasdaq reported the change in 2020 as cited here (and is already an in-line citation):

I saw a new file from LSE Group containing new ICB codes given below, which I expect to address the apparent discrepancies between the listed industry classification in NASDAQ individual stock pages (using ICB) and the more familiar GICS:

To document the discrepancies and the corrections made from new ICB classification codes:

• TSLA: Industry/Auto Manufacturing (New Code & Correction: 401010 – Consumer Discretionary/Automobiles and Parts)
• FAST: Consumer Discretionary/Retail – Building Materials (New Code & Correction: 501010 – Industrials/Construction and Materials)

(ICB notes: New ICB from current ICB Building Materials and Fixtures – 2353, which primarily maps to new ICB: Building Materials: Other – 50101035.)

• TMUS: Telecommunications/Telecommunications Equipment (New Code: Telecommunications/(New Sub: Telecommunication Service Providers (151020) / Telecommunication Services (15102015)) — Correction should be: Telecommunications/Telecommunication Service Providers

(ICB created a second subsector Telecommunication Service Providers under Telecommunications, in addition to existing Telecommunications Equipment. Probably this is a shortcoming of the ICB classification, and NASDAQ was forced to use the single erroneous subclass Telecommunications Equipment, which necessitated ICB to add this new subclass)

• MELI: Real Estate/Real Estate (Correction – classification should be aligned with AMZN: Consumer Discretionary/Catalog/Specialty Distribution)

(The sector I initially indicated there is what reflected in NASDAQ’s website for the stock, but the misclassification seems to be severely palpable)

For the time being, I will be amending the affected stocks with the possible new codes from ICB. It is really egregious for NASDAQ to make those erroneous classifications. Due to Wikipedia standards, however, we have to primarily stick with what’s indicated in the NASDAQ page for the stock unless the editors believe that the stock is misclassified. Nevertheless, the correction should be still within the ICB’s framework for consistency and we cannot insist back to GICS classification, in recognition to NASDAQ’s preferences which I believe was made to align with NASDAQ’s European subsidiaries.
