What to invest in on the stock market? Six stocks to have on your radar in December 2025

KGHM

The state-owned copper giant, KGHM, was on the radar of many investors in November. Company w Ticker Rank searchesi.e. the ranking of companies that arouse the greatest interest among users of the popular website Stooq.pl, was overtaken by, among others, Orlen, which has an almost permanent position at the top of the ranking.

This week, KGHM shares broke the level of PLN 200 for the second time in history, which gives the market value of the plant exceeding PLN 42 billion.. The company had never been at such levels before November this year. It is supported by copper, silver and gold prices on world stock exchanges.

It is worth keeping KGHM on the radar also in December, because on the one hand, the recent increases encourage investment by people who hope that they will be able to ride this wave for a while. Recent recommendations from brokerage house analysts suggested that there is potential for an increase in share prices to around PLN 213-220. On the other hand, these levels are already so close that shareholders should keep their finger on the pulse in case a deeper correction occurs. After over 80 percent growth this year it wouldn't be strange.

Amica

Among the above-mentioned recommendations of stock market analysts from November, Amica, a popular Polish brand of household appliances, deserves a mention Noble Securities has the potential to increase the stock market by approximately 65%. Ultimately, one share may be worth PLN 97.90, and at the end of November they could be purchased on the stock exchange for approximately PLN 59. This is a significant breakthrough that cannot be overlooked by investors.

“The first half of 2025, despite the continuing pressure on sales decline, was dictated by savings, which was visible in the second quarter, when the company surprised with a gross margin on sales of 28 percent. We consider it a good prognosticator for subsequent periods” – comments Mateusz Chrzanowski from Noble Securities.

In its recommendation, Noble Securities forecasts Amica's sales in the second half of the year at a level similar to last year, which will allow it to close 2025 with an EBITDA profit of PLN 133 million (+6.3% y/y) and PLN 24 million of net profit (+80% y/y).

The increase in Amica's valuation is expected to be supported by the ongoing restructuring of foreign subsidiaries, the return of greater demand for household appliances and production optimization.

Medicalgorithmics

Among the favorites of brokerage house analysts is also a Polish company from the telemedicine industry, which is also expanding on foreign markets. Medicalgorithmics specializes in non-invasive cardiac diagnostics using modern software and algorithms based on artificial intelligence (AI). The main area of ​​activity is the analysis of ECG signals and the detection of cardiac arrhythmias. The flagship product is the PocketECG system.

According to the latest recommendation of East Value Research (EVR) Medicalgorithmics shares have the potential to grow by more than 50%. up to PLN 48.60. At the end of November, they could be purchased on the Warsaw Stock Exchange for approximately PLN 32, after the company's quotations dropped compared to October throughout the month.

“Medicalgorithmics' results for the third quarter and nine months of 2025 were better than our expectations. They reflect the impact 19 new customers acquired so far in 2025.including the fifth largest independent diagnostic facility (IDTF) in the USA,” points out Adrian Kowollik from EVR.

He notes that at the beginning of November, the company also signed a new agreement for the use of the DeepRhythm Platform (DRP) with one of the largest IDTFs in Great Britain and Ireland, which, according to estimates, generates over PLN 100,000. ECG reports annually.

Polenergy

Controlled by the richest Pole, Dominika Kulczyk, Polenergia recorded a net loss of PLN 11.3 million in the third quarter of 2025. This is the second quarter in a row with a loss, which has not happened to this company in eight years. The data shows that the key generator of results, i.e. windmills, achieved a quarter lower profits than a year earlier, and the company is starting to repay large debts incurred for investments in the Baltic Sea.

It is worth keeping Polenergia on the radar, because according to analysts of the BOŚ Brokerage House, the company's shares are overvalued, or at least their valuation suggests that they should be at around PLN 45.50. Meanwhile, at the end of November they were trading at around PLN 58 on the stock exchange. The difference is over 20 percent. It is difficult to find an equally pessimistic recommendation in November.

“The company is in the process of building an offshore segment and has launched the Bałtyk 2 and Bałtyk 3 projects in equal partnership with Equinor. Although the projects may look solid from a long-term perspective, we believe that in the short term, they are likely to be unacceptable to most minority shareholders due to their very large scale. The Company's share in expenditure on these projects is expected to amount to as much as PLN 13.5 billion (compared to the current market value of Polenergia shares of PLN 4.5 billion),” says Łukasz Prokopiuk from DM BOŚ.

He adds that “if everything goes well, from 2028, after the completion of both investments, the company would triple its ability to generate consolidated EBITDA from PLN 0.6 billion to PLN 1.8 billion, but at the same time its net debt should increase to gigantic levels of over PLN 12 billion“.

The analyst emphasizes that he is aware that the projects are organized in a safe manner and that after 2028, operating wind farms will be very good cash generators, but it is expected that Reducing such high debt will be a slow and long process.

Digital Network

In December, it is also worth watching one of the heroes of November, i.e. Digital Network, the leader of the digital outdoor advertising market in Poland. Her shares jumped by over 40% within a month.reaching the highest levels in the several-year history of presence on the Warsaw Stock Exchange.

They have been in an upward trend since the outbreak of the coronavirus pandemic at the beginning of 2020. Then they were valued at a few zlotys, and now they are worth PLN 132.

Digital Network reported a few weeks ago that takes over Braughman Group Media Outdoor, a company operating in the outdoor advertising industry. The transaction was valued at over PLN 130 million. This is expected to at least double Digital Network's share in the outdoor advertising market.

The Management Board of Digital Network plans to update its current investment plans and sales and pricing strategy for 2026 in the coming weeks.

Boom

In December, unlike Digital Network, it is also worth watching one of the antiheroes of November, i.e. Bumech. Only in September it was a star of the Warsaw Stock Exchange, and now a Polish company based in Katowice, specializing in providing services for the coal industry and the production of mining machinery and equipment, saw a decline in shares by approximately 45%.

There is a lot going on around the Katowice company. In recent weeks, she informed, among others: on signing an agreement for the preparation of complete documentation for the MSE-ME1 investment, under which: an energy storage facility will be built.

Later Bumech submitted an offer to purchase 9 million shares of Capital Partners in liquidation for a total price of PLN 1.8 million. As a result, the Katowice company would own 50 percent. all CP shares and would become the largest shareholder. “Immediately after the registration of the increase in the share capital of CP, Bumech will apply to convene a general meeting in order to adopt a resolution on abandoning the liquidation of CP,” the press release reads.

The culmination of November was the publication of financial results for the third quarter of 2025. The Bumech Group recorded a net loss of PLN 3.93 million compared to a PLN 20.85 million loss a year earlier. Her sales in a year dropped from PLN 86.7 million to PLN 65 million.

“The diversification of the Bumech Group's operations is not an addition to the strategy – it is its foundation. We systematically develop new business areas in order to build stable sources of income that are resistant to market volatility. (…) This is why we are simultaneously implementing energy storage projects, developing multi-utility activities, investing in biomass production and entering the defense sector – all these activities create a coherent and long-term strategy for strengthening our market position,” said Vice President Andrzej Bukowczyk after the publication of the results.
