In contrast to the terrifying movements noticeable in some stocks in the pond, FTSE 100 It was mighty in 2025. A 5% boost means that it is on the course for the best month for over two years!

At least part of this depends on some ponderous hitters setting fresh 52-week high.

London Stock Exchange Group

Shares in the infrastructure of financial markets and data provider London Stock Exchange Group (LSE: LSEG) also increased by almost 5% in January. But its value is constantly growing for some time – 35% in the last year itself.

Take a closer look, and it begins to make sense. This year, LSEG plans to introduce fresh functions of artificial intelligence in products he is working on with American Titan technology Microsoft. If everything goes to the set, this development can boost its market share.

The question is how much is valued now. Shares are now trading in a profit forecasting ratio (P/E) of 30. This seems high, taking into account that margins have dropped in recent years. The number of initial public offers in Great Britain (IPO) – another source of income for the company – was also pathetic.

With this in mind, the market response to all -season numbers at the end of February will be fascinating. This is before we thought about what could happen if global markets have continuous hesitation. It is worrying that the actions turned out to be quite unstable during a technological disaster after postpandemical.

Experian

Global data company Experian (LSE: EXPN) is another member of the highest level that operates for shareholders. In fact, it flies in January – it increases by 14% as you write.

At least some of them certainly depends on the encouraging trade update for three months to the end of 2024.Another mighty quarter“It led the company to notification by an 8% boost in revenues. Trade in North America was particularly solid, supported by the business segment.

Again, this is not a supply for value hunters. Experian shares change their hands to 32 times FY25 earnings. So this is probably another candidate for a huge fall, if (and the key word is “if”) the investor’s mood changes down for any reason. It is also worth noting that competition in this work is growing.

Like LSEG, it goes to my observation list for now.

Halma

Completing our trio inventory experiencing a huge rush is a life provider of a technology supplier Halma (LSE: HLMA). Its value increased by a similar percentage to the experiment in January. Based on how he finished 2024, this is not a surprise.

In November, the company’s shares increased by almost 10% in one day after a 13% boost in revenues of half a year (to 1.07 billion GBP) and 18% of the profit hill (up to just over 209 million GBP) were recorded. In addition to the behavior of the guidelines regarding the entire year, the management also chose to boost the transient dividend by 7%.

But Halma is far from budget-friendly to buy. AP/E 34 This budget year makes it the most high-priced of these three. And this growth strategy after buying is naturally dependent on finding a sufficient number of good companies to buy.

Broker Berenberg has a target price of 3250p, but this is another one I prefer to buy when investors are afraid.

For now, I watch them all, but I do not buy yet.
