The stock market is a dynamic landscape, and keeping up with the latest news is crucial for investors. Here's a quick rundown of recent developments concerning Rivian, Marvell, Duolingo, and MACOM Technology Solutions Holdings.
Rivian's Turning Point
Rivian Automotive (NASDAQ: RIVN) has reached a significant milestone. After struggling to turn a profit on its popular electric vehicles (EVs), the company finally posted a positive gross margin in the fourth quarter of 2024. This marks a major step forward for the young company.

The company's first-ever quarterly gross profit was a modest $170 million, with a gross margin rate of 9.8%. This is a significant improvement from the negative 46% a year ago. The automotive segment contributed $110 million in gross profits with a 7% margin, while the software and services segment added $60 million with a 28% margin.
However, analysts caution that Rivian still has a long way to go. "2025 is likely to be both a transitional and transformative year," according to market experts. It remains to be seen if Rivian can sustain its profitability and continue its growth trajectory.
Marvell's AI Disappointment
Marvell Technology (NASDAQ: MRVL), a semiconductor company specializing in data infrastructure, experienced a significant stock drop of nearly 15% in Wednesday's after-hours trading session. This followed the release of its report for the fourth quarter of fiscal year 2025 (ended Feb. 1).
While the quarter's revenue and earnings were largely in line with Wall Street's estimates, investors were disappointed with the company's guidance. In the fast-paced world of artificial intelligence (AI), high expectations are the norm. As one analyst put it, "Being in line with expectations isn't enough in the AI space."

Despite the recent setback, Marvell's stock had an impressive run in 2024, gaining 83.1%. This highlights the volatile nature of the stock market, particularly for companies involved in cutting-edge technologies like AI.
Duolingo and MACOM: Share Adjustments
Oppenheimer Asset Management Inc. reduced its stake in Duolingo, Inc. (NASDAQ: DUOL) by 12.9% during the fourth quarter. The fund sold 180 shares, leaving it with 1,220 shares valued at $396,000, according to HoldingsChannel.com.
Meanwhile, Proficio Capital Partners LLC acquired a new position in MACOM Technology Solutions Holdings, Inc. (NASDAQ: MTSI) in the fourth quarter, purchasing 16,888 shares valued at approximately $2,194,000. Other institutional investors, including UMB Bank n.a., have also adjusted their holdings in the semiconductor company.

These adjustments reflect the ongoing shifts and strategies within the investment community. Staying informed about these changes can provide valuable insights into the market's sentiment and potential future movements.
