The “S” ticker on U.S. exchanges most commonly refers to SentinelOne, Inc. (S: NYSE) , and its most recent ending/closing price shown in the data is $17.51. The exact “ending price” depends on which day you mean, but if you’re asking about the latest available close as of early July 2026, that is $17.51.

Which “S” are we talking about?

The symbol S can refer to a few different things:

  • SentinelOne, Inc. – a cybersecurity company listed on the NYSE under ticker S.
  • In some contexts, people might mean S &P 500 (often written “SPX” or “^GSPC”), but that is not literally ticker “S”.
  • Historically, there were other companies with ticker “S” (e.g., Sprint), but those are no longer active under that single-letter code.

Given current market data, the only active, widely traded U.S. stock with a single-letter “S” ticker is SentinelOne.

Latest ending (closing) price for SentinelOne (S)

As of the most recent full trading day in the data (early July 2026):

  • Previous close: $17.59
  • Latest reported close: $17.51
  • Change: –$0.08 (–0.45%).

Other real-time quotes show slightly intraday prices around $18.00–$18.15 , but those are live/mid-day values, not the official day’s “ending price”.

If you had a specific date in mind (e.g., “ending price of S on 30 June 2026”), the exact number would be different and would need to be looked up in a historical price table for that date.

How to find the exact ending price for a specific date
