After two years in the market’s penalty box, biotech is showing signs of life again — especially in the small-cap and mid-cap segments. While big names like Amgen and Gilead remain stable plays, the real opportunity may lie in earlier-stage firms with breakthrough therapies and cleaned-up balance sheets.

The iShares Biotechnology ETF (IBB) is up nearly 20% year-to-date, its best stretch since late 2020. That shift isn’t just about macro rotation — it’s being driven by clear signals from the FDA, improving funding conditions, and a renewed appetite for M&A.

Regulatory Green Lights Are Back

From 2022 through early 2024, the FDA took a noticeably conservative stance, and approval timelines became longer and less predictable. That began to shift in mid-2024. So far this year, the agency has already approved 22 novel drugs, including several in oncology and rare disease — both high-value targets for small developers.

Companies like Karuna Therapeutics and Day One Biopharma, once considered too speculative, are now viewed as potential takeover targets following clean Phase 3 readouts. Institutional investors, including biotech-focused hedge funds, have started rotating capital back into these names — often before approval, not after.

Big Pharma Needs Pipelines, Not Just Profits

Large-cap pharmaceutical companies are facing an uncomfortable reality: $200 billion in drug revenue is set to go off-patent by 2030, creating a pipeline pressure not seen since the early 2010s. That has triggered a renewed M&A cycle, with Pfizer, Merck, and Bristol Myers all expressing interest in early-stage biotech assets that can be scaled post-approval.

Unlike the megamergers of the past, today’s deals are more targeted and scientific, focused on companies with validated assets, fast-track designations, and clearly defined patient populations. For small biotech firms with orphan drug exclusivity or biomarker-based treatments, this is the moment they’ve been building toward.

Retail Investors Are Returning — Cautiously

Retail traders largely exited the sector after the 2021 bubble burst. But platforms like XBI and ARKG, which track early-stage and genomic medicine stocks, have seen a steady uptick in flows over the past 90 days. Momentum is coming not from hype, but from clinical success and real revenue potential.

The difference now is discipline. Investors are favoring firms with low cash burn, milestone payments from partners, or existing commercial revenue. Companies like Verona Pharma and Argenx are now drawing more attention than speculative gene-editing names that once dominated headlines.

Biotech in 2025 Feels More Like 2013 Than 2021

Ten years ago, biotech began a multi-year bull run as new platforms like immunotherapy and CAR-T took hold. What followed was a surge in innovation — and returns. The current setup shares some key features: low expectations, innovation in oncology and neurology, and a hungry group of acquirers.

The sector still carries risk, especially with interest rates elevated and investor memory fresh from recent drawdowns. But with volatility comes pricing inefficiency, and that’s exactly where savvy investors thrive.

If history’s any guide, the quiet rally happening in biotech right now might be the start of something much louder.
