The FTSE 100 stood at 10,685.37 on Wednesday, September 16, 2026, in a delayed Yahoo Finance quote timestamped 08:47:17 UTC, or 09:47:17 in London. That was 27.24 points, or 0.26%, above Tuesday’s 10,658.13 close. London trading was still under way; this is not a closing report.
A flat start, followed by a modest advance
The vendor’s opening reading was 10,658.22 at 08:00 London time, just 0.09 point above the previous close. By the quoted snapshot, the benchmark was 27.15 points above that opening level. Almost all of the net advance therefore developed after the vendor’s recorded start, rather than arriving as a substantial opening gap.
The reported session range so far was 10,655.82 to 10,712.56. The latest reading lay 27.19 points below the high and 29.55 points above the low, placing it near the middle of that 56.74-point range. Those distances describe the price position at the snapshot; they do not establish the direction of the next move.
Tuesday’s closing reference is corroborated by a dated September 15 closing report. Yahoo’s adjacent daily history shows the same level at one-decimal precision. The difference is rounding, not an additional market move.
FTSE Russell defines the FTSE 100 as the large-company benchmark of 100 highly capitalised blue-chip companies listed in London. Its aggregate gain does not establish that most constituents advanced, and this snapshot contains no verified sector-contribution breakdown.
The next useful comparison is whether subsequent readings retain the gain over Tuesday’s close and where they sit against the morning range. The quote feed is delayed, so its timestamp should travel with the level. A later official closing figure must be reported separately.
