All times ET. 5:42 a.m.: Barbie movie boost to Mattel stock was ‘unexpectedly short,’ JPMorgan warns The “Barbie” boost wasn’t so fantastic after all for Mattel , according to JPMorgan. Analyst Christopher Horvers downgraded the toymaker’s stock to neutral from overweight, citing in part a smaller tailwind from the blockbuster Warner Bros. Discovery movie “Barbie” than anticipated. Horvers also cut $5 from his price target to $19, implying he thinks the stock will shed just 0.1% over the next year instead of climbing. “We believe Barbie provided a significant boost to results in mid-to-late 2023 (concentrated in 3Q),” he wrote in a Monday note to clients. “But the duration proved unexpectedly short and the lap creates difficult comparisons plus a significant wall of worry for investors.” “Barbie” was the talk of the summer , with a huge impact in both in the box office and broader consumer spending . The movie based on Mattel’s iconic doll quickly became a cultural sensation, driving moviegoers to theatres in hot pink and clinching the first-ever cinematic and box office achievement award at the Golden Globes. In addition to the bump to purchasing being shorter than hoped for, Horvers listed other reasons for caution around the stock: Weak 2023 holiday sales within the toy industry, creating a lower base to build on in the new year. Data indicating toymakers will face continued challenges winning wallet share as trends normalize post-Covid. A shorter holiday calendar in 2024. Rising freight costs, which can pressure gross margins. Mattel shares are up less than 1% in the new year. The stock underperformed in 2023, gaining just under 6%. — Alex Harring 5:42 a.m.: Goldman hikes Nvidia price target Things continue to look up for Nvidia , according to Goldman Sachs. The bank raised its price target on the chipmaker to $800 from $625, implying upside of nearly 21% from Friday’s close. Goldman also reiterated its buy rating on the stock. “Consistent with recent years and quarters, we expect Nvidia’s FY4Q (January) results and FY1Q (April) outlook in its core Data Center segment to illustrate the ongoing wallet share shift from general-purpose compute (i.e. CPU) in favor of accelerated computing (i.e. GPU),” analyst Toshiya Hari wrote. “Notably, we are encouraged by various data points from the broader eco-system that point to sustained strength in demand for accelerated computing, including: 1) Early evidence of AI monetization at the likes of Microsoft … 2) constructive commentary on AI-related capital spending by the hyperscalers.” Nvidia is slated to report earnings later this month. Shares are off to a strong start for the year, soaring 33.6%. In 2023, they led the S & P 500 higher with a gain of more than 200%. NVDA YTD mountain NVDA year to date — Fred Imbert
