Introductory sentence in lead

I changed the wording (without the "note a") from "consists of" to "that tracks", in the first sentence:

The Standard and Poor's 500, or simply the S&P 500, is a stock market index that tracks 500 large companies listed on stock exchanges in the United States. It is one of the most commonly followed equity indices. As of December 31st, 2020, more than $4.6 trillion was invested in assets tied to the performance of the index.

I noticed that the previous wording of the article could give an incorrect impression about the relationship between the "index" and the "500 companies" in the index. To clarify this, I considered adding a note with references to the article but ultimately decided against it. However, I still wanted to explain the reasoning behind my edit, which is why I am including this note. Thank you to the user with IP address 49.177.30.125 for making good edits to the article.

I want to make it clear that I have never edited this page before and did not make any changes to the contributions of user ExpandD2003. I believe there may have been a misunderstanding, but there is no excuse for making another editor feel uncomfortable. My edits, which I believe are useful, are made anonymously and should not be a point of contention.

I thought ExpandD2003's edit to the article was the best and clearest so far, and I respect their contributions. However, I am afraid to interact with them in any way and ask that they also refrain from interacting with me on Wikipedia. I understand that I am an anonymous IP address and will avoid editing in areas where ExpandD2003 is active.

Thank you for reading.

How is Volume calculated?

The S&P 500 index reported daily comes with a volume stat as well as the price. Is the S&P 500 volume just the volume of all the shares traded for every component of the index, or is it weighted somehow? 2600:8800:1180:25:7CB4:C4B7:5E65:353A (talk) 21:16, 22 January 2024 (UTC)

Selection criteria market cap is incorrect

The S&P500 market cap requirement is $8 B, not $18 B. The reference (23) is for the S&P Composite 1500. 73.239.153.82 (talk) 14:16, 16 May 2024 (UTC)

look at the reference. the market cap requirement for additions to the S&P 500 is at least $18 billion.

Edit war re mass deletions

@Pats322: To end this edit war, you must obviously understand that including facts about the S&P 500 does not make it an "investing guide" as your edit comment claims. You've blasted various unrelated, factual content out of this article under a vague and false premise. At the very least, you should return the article to its former state and then--if justified--deal item by item with individual passages or charts. The same holds true for the NASDAQ article. Are you aware that your "average edit size" across Wikipedia is minus 641.8 bytes? —RCraig09 (talk) 16:20, 24 July 2026 (UTC)

Pats322 (talk) 13:04, 25 July 2026 (UTC)I am the one who added all of that info to the article in the first place. I also added it to Nasdaq-100. I want it in...It was deleted from Nasdaq-100 because they said it was not encyclopedia content. So why should it be in S&P 500? You editors need to be consistent.

@Pats322: You definitely did not add "all" the information that you deleted. I've just replaced a chart that I inserted. Again: we must justify additions and deletions item by item. The fact that similar(?) material was deleted from another article, does not imply the reasoning in the other article was correct; you can go argue there. If content is neutral and reliably sourced, it does not have to be excluded simply because someone "might" use it in investment decisions as you seem to imply. From what I've seen, the content you now want deleted does not generally violate WP:NOTHOWTO, which is the applicable policy. —RCraig09 (talk) 17:26, 25 July 2026 (UTC)
