Talk:S&P 500

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

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.

Proposal to change the opening words
The opening words of the article are:

"The Standard and Poor's 500, or simply the S&P 500, . .."

The official source cited for the name "Standard and Poor's 500" has no mention of that name! Therefore I propose deleting that name.

 * Good catch. I have replaced it with a reference to Encyclopedia Britannica, which verifies both names. Cilidus (talk) 08:58, 31 March 2022 (UTC)

Wording in the opening
Currently as of 4/2/23 :

"The Standard and Poor's 500, or simply the S&P 500, is a stock market index tracking the stock performance of 500 largest companies listed on stock exchanges in the United States."

The highlighted phrase is missing an article. It either needs to be "of  the 500 largest companies" i.e. absolute top 500 or "of 500 of the largest companies" i.e. a selection from the group of the largest companies. As it is, the sentence is ambiguous and should be corrected by an editor that knows which case applies. Thank you. • Bobsd • (talk) 16:14, 2 April 2023 (UTC)


 * Researched me, and according to the selection criteria listed later in the article, I am going to change the phrase to "500 of the largest". It was an edit a few days ago by 178.127.120.227 changing "large" to "largest" without adding an article for clarification.  • Bobsd •  (talk) 16:39, 2 April 2023 (UTC)

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.
