All times ET. 5:58 a.m.: DataDog shares could jump nearly 23%, according to Wells Fargo Wells Fargo thinks DataDog is headed for a period of outperformance in fiscal year 2024. Analyst Andrew Nowinski upgraded the cloud-based monitoring and analytics platform to overweight and raised his price target by $20 to $150, which suggests 22.9% potential upside for the stock. Shares are up 0.6% this year. “We believe Datadog has many ways to drive upside in FY24, including vendor consolidation, security cross-sell and Gen AI,” Nowinski wrote in a Tuesday note. According to the analyst, the company is seeing an end to cost optimization as customers now focus on modernizing their infrastructure, which should begin to drive consumption. DataDog is winning larger deals as customers consolidate vendors, which has a larger impact on its bookings, he added. Other tailwinds to the stock include DataDog’s opportunity to cross-sell security solutions to existing customers, generative AI workloads potentially accounting for 10% of the company’s annual recurring revenue in fiscal year 2025 and management’s plans to ramp up hiring in fiscal year 2024. — Pia Singh 5:56 a.m.: Loop Capital initiates MongoDB, says it is the ‘de facto standard’ developer platform for cloud apps The recent dip in MongoDB share price is an opportunity for investors, according to Loop Capital analyst Yun Kim. Kim initiated coverage of the database program with a buy rating and $415 price target, which suggests shares could climb 22% over the next year. The stock is down 16.8% year to date. “With our industry checks indicating the pace of new cloud deployments improving since the beginning of the year, we expect MDB growth to show accelerated growth in 2H of the year as these new deployments start to ramp into product in 2H of the year. We don’t believe this scenario is fully captured in current Street estimates,” Kim wrote in a note. “In our view, MDB has emerged as the de facto standard for development platform for cloud applications.” Kim said his price target implies that the company’s revenue multiples are consistent with other fast-growing cloud infrastructure names. MongoDB’s growth trajectory remains strong at 20% overall and 30% just for its cloud Atlas business, which he expects to push the company’s growth in the second half of the year as the pace of new cloud deployments continues to accelerate, he said. MongoDB shares ticked higher by just under 1% in the premarket. — Pia Singh 5:43 a.m.: KeyBanc downgrades beaten-down solar stock Sunnova Energy Heading into first-quarter earnings, KeyBanc Capital Markets is cautious on residential solar names, particularly Sunnova Energy . Analyst Sophie Karp downgraded the Texas-based residential and commercial solar energy company to sector weight from overweight and removed her price target on the stock. Sunnova shares have plunged nearly 75% this year, punished by a higher-for-longer interest rate environment that has been challenging for solar companies’ project financing and cash flows. “The overall residential solar landscape in the U.S. remains challenging due to the combination of lower energy prices and elevated financing costs,” Karp wrote in a Monday note, saying that a lack of encouraging data from the industry suggests that recovery remains elusive. “NOVA specifically is under pressure to demonstrate positive q/q cash movement and to define its capital allocation strategy going forward.” Karp reiterated her sector weight rating on solar peers Sunrun, SolarEdge Technologies and Enphase Energy, meanwhile. — Pia Singh 5:43 a.m.: JPMorgan upgrades Roblox The sell-off in Roblox shares has created a big buying opportunity, according to JPMorgan. The bank upgraded the video game company to overweight from neutral. It also raised its price target to $48 from $41, implying a 37% rally over the next 12 months. “RBLX shares have been volatile since the company’s direct listing in 2021, in many ways reflecting investor enthusiasm — and subsequent skepticism — around the durability of companies that saw usage spikes during the pandemic,” analyst Cory Carpenter wrote. This year alone, shares are down more than 23% after a 60% rally in 2023. That pullback “presents a compelling entry point for a company growing bookings ~20%+, exiting a heavy investment cycle, and ramping two new revenue streams in advertising (2H24) & commerce (2025),” Carpenter said. Roblox shares popped 3% in the premarket following the upgrade. RBLX 1D mountain Roblox rises — Fred Imbert
