On the first trading day of the year, the FTSE 100 index made headlines by exceeding the significant milestone of 10,000 points for the first time, reaching an intraday peak of 10,046 before closing the day at 9,951. This surge marks a notable achievement for the index, reflecting a remarkable increase of more than 21% compared to the previous year when it was just over 8,260.
The strong performance of shares included in the index throughout 2025 contributed to this growth. Notably, British brands like Currys and Next saw significant gains, while companies in sectors such as precious metals, defense, and financial services also prospered. Interestingly, this London-based index exceeded the performance of major American stock indexes during the same period, despite ongoing discussions regarding elevated stock valuations in the US.
The FTSE 100, which gauges the performance of the 100 largest companies listed on the London Stock Exchange, generates a substantial portion of its revenues—approximately three-quarters—internationally. This means that while a rise in the index could signal positive trends for investors, including those with pensions invested in the stock market, it doesn’t necessarily reflect the performance of the UK economy directly.
Prominent firms like Rio Tinto benefited from soaring prices in gold and silver, while increased global defense spending aided contractors like Babcock and Rolls-Royce amid rising economic uncertainty and geopolitical tensions. The early trading session after the New Year’s holiday saw the index rise swiftly by more than 1%, showcasing the enthusiasm among investors as the year began.
Independent financial commentator Susannah Streeter emphasized that breaching the 10,000-point barrier is a “psychologically important milestone,” indicating that London’s blue-chip index is gaining favor among investors. The perception of US tech valuations has influenced some investors to turn their attention to the UK market, which is seen as presenting more attractive opportunities.
Dan Coatsworth from investment platform AJ Bell described the surpassing of 10,000 points as a “New Year’s gift” for Chancellor Rachel Reeves, who has been advocating for increased investment in shares to stimulate economic growth. He noted that despite the tendency to view London-quoted companies as “old and boring,” the diversity of industries, including mining and banking, appeals to those seeking stability in uncertain times.
Chancellor Reeves acknowledged the milestone as a “vote of confidence” in Britain’s economy and a promising start to 2026. Even though the FTSE 100 is often regarded as a reflection of the UK’s corporate landscape, the gains largely mirror global market activity, with many companies deriving substantial revenues from international operations.
The index’s resurgence aligns with a broader trend seen across global stock markets driven by anticipation regarding advancements in artificial intelligence (AI) potentially boosting corporate earnings. However, experts caution that should the burgeoning excitement over AI fail to materialize or take longer than expected, it could lead to a swift decline in share values.
In this lively market context, the performance of individual companies varied significantly. Fashion retailer Next raised its profit outlook multiple times over the year, while luxury brand Burberry rebounded from consecutive annual losses to achieve profitability again. Conversely, bakery chain Greggs faced a tumultuous year, seeing its shares drop 39% amidst concerns over its expansion strategy and underwhelming sales growth. Diageo and WH Smith also experienced sharp declines, reflecting the volatility and unpredictability investors face in this dynamic market landscape.
