Historical context

254 sessions

Volatility10.0%
44th percentile of the last 234 readings — typical. Annualised from the last twenty sessions, then ranked against the same calculation on every twenty-session window of the past year.
Latest session+0.14%
21st percentile of the last 253 readings — below typical. Ranked on size and not direction, so an unusually large fall reads as unusual rather than as a low return.
Five sessions+0.34%
49th percentile of the last 249 readings — typical. Ranked among every five-session change of the past year, direction included.
Twenty sessions-0.90%
18th percentile of the last 234 readings — low. Ranked among every twenty-session change of the past year, direction included.

A percentile is the share of the past year’s readings at or below the current one. The multi-session rows keep direction, so a high rank there means a strong rise; volatility and the latest session are ranked on size alone, so a high rank means a large move either way. All of it describes how ordinary today is by this instrument’s own standards, which is a statement about the record and not about what happens next.

Reported context

Written by sonar-pro

Recent reports say the FTSE 100 has been affected by movements in oil prices, elevated bond yields and developments in the Middle East, including US-Iran talks and tensions around Saudi Arabia. On 25 September, lower oil prices and gains in banking and mining shares helped the index rise 0.1% to 10,695.25 at the close. The index had fallen for three consecutive trading days by 24 September and was down 1.33% month to date, according to reported market data.

What these figures mean

Written by gpt-5.4-mini

Over the trailing year, the FTSE 100 rose by 16.2%, while its annualised volatility of 11.5% means its price typically moved around by a little over 11% over a year, rather than staying flat. The largest peak-to-trough fall was -9.3%, which means that at one point it dropped 9.3% from a previous high before recovering later in the period. With a period high of 10,910.60 and a period low of 9,214.00, the current price being 88% of the way from the low to the high means it is much nearer the high than the low.
