The FTSE 100 is one of the most closely watched indicators of the UK equity market. It tracks 100 of the largest companies listed on the London Stock Exchange and provides a useful snapshot of how major listed businesses are performing. For anyone searching for the FTSE 100 index today, the most useful information includes the current level, daily percentage change, trading range, live chart and the news influencing market movements.
On 28 September 2026, the market snapshot for the FTSE 100 showed an index level of 10,747.89, up 52.64 points, or 0.49%, at 15:14 BST. The day’s opening level was 10,695.19, while the intraday high was 10,758.74 and the low was 10,688.59. These figures provide a useful example of how to interpret an index during an active trading session rather than relying on the headline percentage alone.
Understanding the FTSE 100 Index Today
The FTSE 100 represents 100 large companies listed on the London Stock Exchange, with constituents selected according to market capitalisation. Because the companies differ significantly in size and sector, movements in larger constituents can have a greater influence on the overall index. The index therefore offers a broad view of major UK-listed shares, although it should not be treated as a complete measure of every company or business operating in Britain.
The index level is not a pound price for an individual share. Instead, it is a calculated measure representing the combined performance of its constituents according to the index methodology. Investors usually look at the level alongside its percentage movement and points change. This makes it easier to understand whether the market is rising or falling during a particular session and how significant that move is relative to recent trading.
Current Level and Daily Movement
When checking the FTSE 100 index today, the first figures to examine are the current level, previous close, opening level, daily high and daily low. Together, these numbers show how the market has behaved during the session. A current level above the previous close indicates a gain for the session, while a figure below it indicates a decline. The size of the move is usually displayed in both points and percentage terms.
The 28 September market snapshot also showed a previous close of 10,695.25, compared with the intraday level of 10,747.89 at 15:14 BST. The difference illustrates why timestamps matter when reading market information. An index can move considerably between the opening bell and the end of trading, so readers should always check when a displayed figure was recorded rather than assuming every website is showing precisely the same moment.
FTSE 100 Live Chart and Daily Performance
A live chart gives additional context that a single number cannot provide. It allows readers to see whether the index has moved steadily, experienced sharp fluctuations or traded within a relatively narrow range. Looking at the day’s high and low can also show the width of the trading range. This is particularly useful when the percentage change appears modest but the index has moved substantially during the session.
The FTSE 100 index today can also be compared with previous sessions to understand short-term momentum, although one trading day does not establish a long-term trend. Charts covering several weeks or months can provide a wider perspective, while a 52-week range shows where the current level sits relative to the previous year’s trading extremes. These measures should be viewed as historical context rather than automatic indicators of what happens next.
What Is Moving the FTSE 100 Today?
Several sectors can influence the FTSE 100 at the same time. Housebuilders, miners, banks, energy companies, pharmaceutical businesses and consumer firms can respond differently to economic developments and company-specific news. Because the index contains businesses with international operations, movements in currencies, commodity prices and overseas markets can also affect individual constituents and, in turn, the overall index.
Market reports on 28 September highlighted a rally in UK housebuilders after the government announced a state-backed equity loan initiative for first-time buyers. Reuters reported that the broader European market also gained, while weaker metals and higher oil prices helped limit some of the upside. This illustrates why the FTSE 100’s daily movement can reflect several competing forces rather than one single event.
FTSE 100 Performance and Key Market Indicators
Percentage change is one of the simplest ways to interpret daily performance. For example, a gain of 0.49% indicates that the index was higher than its previous close by that proportion at the recorded time. The points change gives the absolute difference in index points. Both figures describe the same general movement but present it from different perspectives.
The 52-week high and low can provide another useful reference point. In the market information supplied for this article, the 52-week high was 10,989.45 and the 52-week low was 9,266.29. Comparing the current level with these figures can show whether the index is trading relatively close to a recent extreme. However, this comparison describes where the market has been; it does not establish where it will go next.
FTSE 100 News, Companies and Market Sentiment
News affecting individual companies can sometimes have a noticeable impact on the index, particularly when the company has a substantial weighting. Corporate results, acquisitions, trading updates, regulatory developments and changes in expectations can all influence share prices. Sector-wide developments can have an even broader effect when several constituents respond to the same economic or political event.
The international nature of many FTSE 100 companies is also important. Although the index is associated with the UK market, many constituents generate significant revenue outside Britain. Currency movements can therefore influence reported earnings and investor sentiment. Commodity prices can also matter for major mining and energy businesses. This is one reason the index can sometimes behave differently from indicators focused more heavily on domestic UK companies.
How to Follow the FTSE 100 Live
Readers looking for the FTSE 100 index today can use several financial information services to monitor the market. The London Stock Exchange provides official market information, while financial platforms such as Yahoo Finance, Hargreaves Lansdown and TradingView provide charts and additional market data. The information displayed by different providers can vary slightly because of timing, calculation methods and whether the data is delayed.
Before comparing two figures, check the timestamp and whether the service identifies its data as real-time or delayed. The London Stock Exchange states that some displayed market data can be delayed by at least 15 minutes. This is particularly important during periods of rapid movement, when even a short delay can result in noticeably different index levels between platforms.
Conclusion
The FTSE 100 remains an important reference point for following large UK-listed companies and understanding daily movements in the London market. Checking the current level alongside the previous close, percentage change, intraday range and chart provides considerably more information than looking at a single headline figure. News and sector movements can then help explain why the index is moving in a particular direction during the session.
For readers monitoring the FTSE 100 index today, the key is to combine current market data with its timestamp and wider context. The index is a useful snapshot of major listed companies, but it does not represent every part of the UK economy or every UK-listed business. A balanced view therefore comes from considering price data, company news, sector performance and longer-term market history together.
