Chart to Watch: Biotech bounces back
Optimism is returning to the biotech space as clinical successes, a pickup in M&A activity, and easing regulatory concerns have driven a substantial performance turnaround.

Key takeaways:
- While biotech stocks saw a steady drawdown from the U.S. presidential election through early April, the Nasdaq Biotechnology Index has fully recovered from its post-election low and development stage biotech stocks are up over 75% since April 8.
- Biotech stocks have gained traction due to positive clinical trial data, new product launches, and a strong pace of FDA drug approvals. Increasing merger and acquisition (M&A) activity and the prospect of lower interest rates also bode well for the sector.
- We believe durable performance drivers are in place as policy overhangs on the sector lift and innovation and medical advances continue.

Source: Bloomberg. Cumulative total return as of 11 September 2025. Drawdown = U.S. election on 5 November 2024 through April low on 8 April 2025. Recovery = 8 April 2025 through 11 September 2025. Full period = 5 November 2024 through 11 September 2025.
Though we remain mindful that there could be near-term volatility as drug pricing policy is finalized, we believe the most acute phase of policy uncertainty for biotech may be behind us. And, given the recent uptick in M&A activity, the industry seems to agree. With Big Pharma facing numerous patent expirations in coming years, we’d expect this activity to continue, particularly in a more accommodative interest rate environment. It’s worth noting that, in the past, a resurgence of M&A activity has been a catalyst for recoveries from biotech downturns. Also of promise is the fact that the FDA has approved 36 new medicines in 2025, on pace with 2024, and positive clinical trial data and product launches highlight that the biotech sector remains a hub of innovation.
