Reports & Presentations
Monthly performance
In January, the biotechnology sector started the year on a constructive note, supported by a positive backdrop around the J.P. Morgan Healthcare Conference. Investor focus centred on companies with advanced pipelines, clear regulatory visibility and credible commercial prospects, which was reflected in improved financing activity. Strategic buyers once again emphasised the importance of external innovation for their R&D pipelines, while the IPO market remained selective. As the month progressed, macroeconomic and monetary policy uncertainty came further into focus, leading to increased volatility. Overall, January reinforced a renewed emphasis on fundamentals and a selective, data-driven risk management approach within the biotechnology sector.
