What this dated FTSE 100 record means

For FTSE 100, local trading hours and the observation timestamp control the description. A pre-open latest close is historical; an intraday value remains unfinished until the closing process. The FTSE 100 snapshot is a historical checkpoint. CapKet preserves later observations at different URLs so that publication order and market evolution remain auditable.

Why the observation mattered

FTSE 100 is a benchmark for the largest London-listed companies. The useful comparison for FTSE 100 is another observation with the same unit, source method and market state. A later number without those controls can create a false impression of precision.

What readers were watching

Watch sterling, gilt yields, energy shares and Bank of England expectations. The archived FTSE 100 reading remains useful only with its limitations visible. Replacing it silently with today’s quote would erase the factual record and misstate the article’s age.
