EV Maker Rivian Beats Expectations for Deliveries as Supply Snag Eases

Rivian stock jumped 20.8% this week. Rivian surpassed analysts' expectations for fourth-quarter deliveries on Friday and said its production was no longer constrained by a component shortage, a positive sign for the electric vehicle maker aiming to turn its first profit.

Rivian handed over 14,183 vehicles in the three months ended Dec. 31, compared with estimates of 13,472, according to 15 analysts polled by Visible Alpha.

That was a 42% jump from the previous quarter and marked Rivian's highest deliveries in more than a year, even though Amazon.com AMZN.O, its biggest backer, takes fewer deliveries in the fourth quarter due to its focus on holiday season sales. Rivian produced 12,727 vehicles in the quarter, compared with estimates of 11,398 units.

MINISO Stock Soars 14% on Strong Financials and Booming ACG Goods Strategy

MINISO Group Holding Limited saw its stock surge 14.55% this week, following the company's positive financial performance and successful strategy in tapping into the booming ACG (animation, comics, games) goods market.

MINISO has demonstrated robust financials, with a remarkably high return on equity (ROE) of 28% and an impressive 70% earnings growth over the past five years, outperforming the industry average.

ARM Holdings Soars 9% as Microsoft's $80B AI Spend Spurs Growth Optimism

Shares of ARM Holdings, a leading semiconductor design company, soared 9% this week, as the company was caught in a wave of optimism surrounding the growth prospects of the artificial intelligence (AI) industry.

The rally in ARM's stock price was likely fueled by a blog post from Microsoft's Vice President Brad Smith, who disclosed that the tech giant plans to invest $80 billion in building AI data centers in the current fiscal year ending in June. This massive spending plan signaled Microsoft's unwavering commitment to the AI sector and its belief in the transformative potential of the technology.

As a key player in the AI semiconductor ecosystem, ARM stands to benefit significantly from the surging demand for chips powering AI applications and data centers. The company's low-power chip architecture is increasingly being adopted in AI-focused chips designed by major cloud providers and chipmakers like NVIDIA, further solidifying ARM's position in this lucrative market.
