The major U.S. stock indexes experienced a slowdown at the beginning of December after a positive week at the end of November. The Nasdaq edged down by 0.4%, the S&P 500 fell by 0.5%, and the Dow saw a decline of 0.9%. For further details, the market movements of that day can be checked.
Moderna (MRNA), largely reliant on COVID-19 vaccine sales, saw a 7% drop, leading the losses within the S&P 500 index. This decline was triggered by reports indicating that the Food and Drug Administration intends to revamp its vaccine assessment process, now requiring greater evidence of both safety and effectiveness. Other vaccine producers like Novavax (NVAX), BioNTech (BNTX), and Pfizer (PFE) also experienced stock declines.
SanDisk (SNDK), known for memory cards and other data storage solutions, saw its shares fall nearly 6%. With this downturn, SanDisk reversed last week’s gains fueled by excitement over its S&P 500 listing. Even with this fall in December, the stock has significantly risen since the spinoff from Western Digital (WDC) earlier this year, driven by AI-related memory demand.
Meanwhile, despite glimpses of recovery last week, Bitcoin (BTCUSD) and other major cryptocurrencies took a hit on Monday. Coinbase Global (COIN), a cryptocurrency exchange operator, saw its shares decrease by about 5%, and Robinhood Markets (HOOD), which offers cryptocurrency trading, faced a 4% drop.
Synopsys (SNPS) emerged as the top stock performer on Monday, with its shares climbing by about 5% after announcing an expanded partnership with AI chip leader Nvidia (NVDA). As part of the agreement, Nvidia will invest $2 billion in Synopsys and both companies will work together on AI applications. Nvidia’s stock rose by 1.7% as well.
Shares of footwear and apparel brand Deckers Outdoor (DECK) increased by 4.5%. Late last month, analysts from Stifel upgraded Deckers’ stock from “hold” to “buy,” citing promising growth for the Hoka footwear line, strong demand for its Ugg brand, and robust international sales. The company even provided a rare discount on Hoka sneakers during Black Friday.
Additionally, two logistics companies saw stock increases following optimistic assessments from BMO Capital analysts. Shares of Old Dominion Freight Line (ODFL) and JB Hunt Transport Services (JBHT) each rose over 3% after receiving an “outperform” rating from the analysts.
