Novavax (NVAX) stock analysis, August 29, 2025: FDA approval, but restricted access: can NVAX hold $7.69?

Published August 29, 2025 · NVAX chart, levels and live analysis

Key Updates

Novavax shares recovered 2.67% to $7.69, staying volatile after the FDA approved its updated COVID-19 vaccine. The company received full Biologics License Application (BLA) approval for Nuvaxovid, a major milestone for the drug's regulatory status. But the FDA restricted access to updated COVID vaccines to older people and high-risk groups only, which could cap the potential market.

Current Trend

The stock is mixed, with a short-term rebound of +12.26% over the past month but a longer-term decline of -4.35% YTD and -7.68% over six months. The current level of $7.69 reflects an attempt to stabilize after a series of volatile moves tied to FDA decisions. The 2.67% gain since the last report points to a positive market reaction to the full BLA approval.

Investment Thesis

The Novavax thesis rests on its position as an alternative COVID vaccine maker using protein-based technology, a different approach from competitors' mRNA platforms. Full FDA approval for Nuvaxovid strengthens the company's regulatory standing and potentially opens new commercial opportunities, despite a narrower target audience.

Thesis Status

The thesis has improved with the key regulatory milestone of BLA approval. However, the FDA's restriction of vaccines to older and high-risk groups creates challenges for scaling commercial potential. Inclusion on a list of cheap biotech stocks favored by hedge funds also points to possible undervaluation.

Key Drivers

The main positive driver is full FDA approval of the Nuvaxovid BLA, which bolsters the company's regulatory position. But FDA limits on updated COVID vaccines to older and high-risk groups are a hurdle to broad commercial use and could cap potential sales revenue.

Technical Picture

Shares are trading at $7.69 after a 2.67% bounce, showing an attempt to stabilize around current levels. The monthly gain of 12.26% signals short-term bullish momentum, but the negative YTD (-4.35%) and six-month (-7.68%) trends point to lingering selling pressure. Recent volatility reflects market uncertainty over the company's commercial prospects.
