Summary of Key Wall Street Ratings: UBS raises AMD target price to $670, Seaport maintains Nvidia sell rating BlockBeats News: On Wednesday, June 24th, multiple Wall Street institutions announced significant rating adjustments involving companies such as NVIDIA, Tesla, AMD, Reddit, Arm, and others. Among them, Seaport reiterated its "sell" rating on Nvidia, stating that the burden on Nvidia's balance sheet and off balance sheet continues to increase, and Broadcom has also joined the trend of revolving financing, indicating that the AI industry is facing rising financing constraints. Stifel has covered BlackBerry for the first time and given it a 'buy' rating, stating that the market still misunderstands BlackBerry. The company is no longer just an automotive supplier, but a key software layer in the physical AI stack, and has partnered with chip companies such as Nvidia, Qualcomm, and AMD. UBS reiterated AMD's "buy" rating and raised its target price from $470 to $670, stating that it is more positive about AMD as independent CPU racks begin to gain market recognition. TD Cowen reiterated Arm's "buy" rating and raised the target price from $265 to $475, stating that Arm's $15 billion AGI CPU target for fiscal year 2031 is reasonable, but GPU to CPU pairing and single core pricing remain key variables. RBC reiterates Tesla's "outperform the market" rating, expecting Tesla to deliver 405000 vehicles in the second quarter, higher than the Visible Alpha consensus expectation of 401000 vehicles. Needham reiterated Reddit's "buy" rating, stating that Reddit has a rare competitive position and is largely unaffected by the proxy AI storm. In addition, Citizens has for the first time covered Bitdeer, CleanSpark, Keel Infrastructure, and MARA Holdings, all of which have given a "outperform the market" rating, stating that these Bitcoin mining companies are shifting their existing power capacity to provide high-performance computing power to ultra large scale customers and large enterprises.
