The move comes amid a broader trend of underperformance relative to peers and a challenging fundamental backdrop.

What Happened

Novavax Inc. stock has fallen sharply in the session, with the stock opening near $9.85 and quickly trending downward.

The stock has traded at a volume of 0.8 million shares, which is 0.2 times the 3-month average, suggesting limited participation in the move. The decline is part of a broader pattern of weakness, with the stock printing four fresh 52-week lows on September 10.

What The Data Shows

The stock has traded in a wide range this year, from $6.20 to $11.97, and currently sits near the lower end of that range. The company remains unprofitable with a trailing twelve-month net margin of -59.9% and a revenue decline of 61.6% year-to-date. The stock has a beta of 2.45, making it highly volatile compared to the broader market. The recent underperformance is also reflected in the intraday session shape, with the stock unable to maintain early gains and showing a steep decline in the first two hours of trading.
