We have seen this month the highest level ever for the blue sheet FTSE 100 The leading British stock index. This happened on multiple occasions this year.

However, in 2025 it was filled with economic certainty of a large number of reasons, from geopolitical tensions to uncertainty over international tariff systems. Meanwhile, the British economy does not seem to be healthy at all.

So, why are FTSE 100 – and how can investors think about interaction?

Many love, but a lot to worry!

FTSE 100 has a group of different companies.

Some focus on the UK market, while others do most of their business abroad. Some are in mature industries, while others have stronger growth prospects. Some flow on huge sums of excess cash, while others are struggling with their profit.

So I do not see a necessary contradiction between the slow -looking economy and the performance of FTSE 100. Some index companies were performing a strong performance recently.

Meanwhile, the nature of the indicator and its quarterly membership reviews means that companies that have increasing market heads are more likely to keep it inside, while others who suffer from volatile assessments can leave it.

But while the indicator is on the gangs, the broader economic performance ultimately affects FTSE 100 in the long run. I still have some concerns about this result, although it may set some new records in the coming months.

The growth expectations for the UK economy are still noticeable. Although FTSE 100 is still cheap for its counterpart in the United States, its evaluation no longer seems to me like the potential deal I made two years ago.

Buy individual stocks

This is one of the reasons why I have no plans to invest in the FTSE 100 Tracker Fund.

But the main reason is that I prefer to buy individual shares instead of tracking the index.

Although the FTSE 100 index was high, all the shares in it were working well.

For example, keep in mind JD SPORTS (LSE: JD). The share price decreased by 32 % in only one year. Och!

This is not without reason. It also revealed a commercial update today, the sales similar to the first half of the year decreased by 2.5 %. Impressive, sales performance similar to the material was worse in the second quarter of the first quarter in Europe and the United Kingdom.

This can indicate twice the continuous demand in the future, although the company reported a stronger direction in the second quarter of Asia and the Pacific. North American sales decreased similar, but less than the first quarter.

But similar sales such as do not tell the full story. Thanks to the opening of more stores, the company’s total sales continue to grow.

It is highly profitable and gives it an increasingly global imprint. With its broad program for the store in recent years, JD’s capital expenditures are scheduled to decrease, which helps in profitability.

Although it continues to assess the potential impact of American definitions, JD SPORTS now expects this year before taxes and adjusts the elements to match the expectations of analysts. They are currently sitting in the range of 852 million pounds-915 million pounds.

Against, the market value of JD SPORTS is less than 5 billion pounds is low for me. I think it’s one of the FTSE 100 posts that investors should take into account.
