On June 24, several Wall Street institutions released important rating adjustments involving companies such as Nvidia, Tesla, AMD, Reddit, and Arm. Seaport reiterated its 'Sell' rating on Nvidia, citing increasing burdens on Nvidia's balance sheet and the trend of Broadcom joining in on revolving financing, indicating that the AI industry is facing rising financing constraints. Stifel initiated coverage on BlackBerry with a 'Buy' rating, stating that the market continues to misdefine BlackBerry, which is no longer just an automotive supplier but a key software layer in the physical AI stack, collaborating with chip companies like Nvidia, Qualcomm, and AMD. UBS reaffirmed its 'Buy' rating on AMD and raised the target price from $470 to $670, expressing a more positive outlook as independent CPU racks begin to gain market recognition. TD Cowen reiterated its 'Buy' rating on Arm and raised the target price from $265 to $475, stating that Arm's $15 billion AGI CPU target for fiscal year 2031 is reasonable, although the GPU and CPU pairing rate and single-core pricing remain key variables. RBC reaffirmed its 'Outperform' rating on Tesla, expecting Tesla's second-quarter delivery volume to reach 405,000 vehicles, exceeding the Visible Alpha consensus estimate of 401,000 vehicles. Needham reiterated its 'Buy' rating on Reddit, noting that Reddit possesses a rare competitive position, largely unaffected by the proxy AI storm. Additionally, Citizens initiated coverage on Bitdeer, CleanSpark, Keel Infrastructure, and MARA Holdings, all giving them 'Outperform' ratings, stating that these Bitcoin mining companies are repurposing their existing power capacity to provide high-performance computing capabilities to hyperscale customers and large enterprises.
