Unveiling the January Effect: Europe's Top Stock Picks for a Powerful Start
A new year, a fresh opportunity for investors! European stock markets have kicked off 2026 with a bang, setting new records and igniting excitement. But here's where it gets interesting: January, typically a modest month for European stocks, has been delivering some extraordinary performances lately.
Seasonal patterns suggest a positive, if unremarkable, January for European equities. Yet, recent years have seen the opening month surprise with powerful rallies, especially for a select few. And this is the part most people miss - the hidden gems that shine in January.
According to TradingView, the Euro STOXX 50 has averaged a modest 0.26% gain in January over the past 20 years, finishing higher 56% of the time. National indices like Germany's DAX and France's CAC 40 show similar patterns, with average gains of 0.44% and 0.58%, respectively. However, Italy's FTSE MIB stands out with an average 1.23% rise and a 62% success rate.
While months like April or November have historically offered stronger returns, what sets January apart in this cycle is the magnitude of recent gains. January 2023 and 2025 ranked among the strongest on record for several European indices. The Euro STOXX 50 surged an impressive 9.75% in January 2023 and added another 7.98% in 2025. Similarly, Germany's DAX rose 8.65% and 9.16% in those years, indicating a renewed appetite for cyclical and industrial stocks.
Amid this backdrop, certain stocks have consistently outperformed in January. Here are five European companies with a remarkable seasonal track record, favoring the first month of the year:
Alten SA: This French engineering and technology consultancy boasts a clear positive bias in January. Over the past 20 years, Alten's stock has averaged a 4.13% gain during the month, finishing higher 71% of the time. Recent years have been particularly strong, with gains of 20.46% in 2023, 6.84% in 2024, and 12.9% in 2025. However, the global financial crisis in 2008 and 2009 saw notable exceptions, reminding us that even strong seasonal trends can be overshadowed by macro shocks.
Accor SA: French hospitality group Accor is another reliable January performer. Over the last two decades, Accor's stock has averaged a 4.3% gain in January, with a 67% win rate. The pandemic recovery phase has seen particularly strong momentum, with all four Januarys since then ending positively. January 2023 was exceptional, with a 28.1% surge as travel demand rebounded sharply.
Sopra Steria Group SA: French IT consultancy Sopra Steria boasts one of the most consistent January records among mid-to-large European stocks. Over the last 20 years, Sopra Steria shares have averaged a 5.75% gain in January, with a strong 76% win rate. Excluding the 2022 drop, every January in the past eight years has ended positively. The best performance was in January 2012 with a 23.25% rally, while the worst was during the financial crisis in 2008, with a 22.76% decline.
Sartorius AG: German life sciences supplier Sartorius is another prominent January performer. Over the past two decades, the stock has averaged a 5.85% gain in January, with a 67% win rate. Excluding the 2022 sell-off, the last eight Januarys have all been positive. January 2025 was exceptional, with a 30.11% jump, reflecting renewed investor interest in high-quality healthcare suppliers. The weakest January was in 2008, with a 12.96% decline.
Rheinmetall AG: Topping the leaderboard is German defence giant Rheinmetall, with one of the most striking January patterns in Europe. Over the past 20 years, Rheinmetall's stock has averaged a 7.74% gain in January, with an impressive 90% win rate. Recent years have been particularly strong, with double-digit gains in the past four years: 10.9% in 2022, 15.02% in 2023, 13.17% in 2024, and a whopping 22.9% in 2025. This consistency reflects structural tailwinds for the defence sector and early-year repricing as investors reassess geopolitical risks.
Seasonal patterns offer valuable insights into investor behavior and expectations. However, they are not foolproof and can be overshadowed by macroeconomic events, policy changes, or geopolitical surprises. While January may not be Europe's strongest month on average, it has often provided an early boost for a select group of stocks.
Remember, investing involves risks, and past performance is no guarantee of future results. Always conduct your own research and consult experts before making investment decisions. We aim to provide guidance, but the responsibility for your investments lies with you. Happy investing, and may your January be as bright as these European stocks!
