Key Movers in the Stock Market: Rocket Lab, Bavarian Nordic, H&R Block, and More

In midday trading, several stocks showed significant movement, driven by a combination of company-specific news and broader market dynamics. Among the top gainers, Rocket Lab surged over 16%, reaching a 52-week high after successfully packing and shipping two Mars-bound spacecraft to Cape Canaveral for launch. These spacecraft were developed in collaboration with NASA and the University of California Berkeley’s Space Sciences Laboratory, reflecting Rocket Lab’s growing reputation in the space exploration industry.

Bavarian Nordic, a Danish biotech firm, also saw a sharp rise of more than 16% after it submitted data to the European Union’s drug regulator to extend the use of its mpox vaccine to teenagers. This move is seen as a crucial step in addressing the latest strain of the virus, with CEO Paul Chaplin emphasizing the importance of expanding vaccine approval for individuals aged 12 to 17.

Tax services provider H&R Block experienced a jump of over 16% following its fiscal fourth-quarter results, which exceeded Wall Street estimates. The company not only raised its dividend but also authorized a $1.5 billion stock buyback, signaling confidence in its continued growth. H&R Block’s positive outlook for fiscal 2025, projecting another year of revenue increases, further boosted investor sentiment.

Bayer, the German life sciences giant, climbed more than 10% after winning a legal battle related to its Roundup weed and grass killer. The lawsuit had alleged that exposure to Roundup led to cancer, but Bayer’s recent court victory has eased concerns among investors, contributing to the stock’s rise.

Chinese e-commerce leader JD.com rose more than 5% after reporting stronger-than-expected quarterly earnings. The company’s second-quarter earnings surged 74% year over year, driven by price cuts that attracted cost-conscious consumers. This robust performance exceeded analysts’ expectations, reaffirming JD.com’s competitive position in the market.

In contrast, Applied Materials, a leading semiconductor equipment manufacturer, saw a 3% decline despite posting better-than-expected fiscal third-quarter results. Although the company’s earnings per share and revenue met expectations, the stock’s recent gains of 51% over the past year may have led to some profit-taking.

Packaging giant Amcor slid more than 5% after reporting slower sales in the latest quarter. The company’s net sales fell to $3.54 billion, down from $3.67 billion a year earlier, missing analyst expectations. Amcor faced declines in both its rigid and flexibles segments, contributing to the stock’s downward movement.

Finally, Coherent, an electronics manufacturer, gained 3.1% after exceeding Wall Street’s expectations in its fiscal fourth quarter. The company reported earnings of 61 cents per share on revenue of $1.31 billion, slightly above analysts’ predictions. Meanwhile, Sphere Entertainment rose 6.2% following an upgrade by JPMorgan, which highlighted the success of the company’s Las Vegas Sphere venue as a key attraction in the tourism market. Sphere’s plans to expand internationally also bolstered investor confidence.
