Why AI Stock Broadcom Crushed It in June
Although the chipmaker's latest quarterly results only beat analyst estimates modestly, they featured impressive growth figures. Meanwhile, the company rolled out a new product and was the subject of numerous bullish prognosticator updates. 10 stocks we like better than Broadcom › With a nearly 14% share price gain in June, Broadcom (NASDAQ: AVGO) was a clear stock market winner during the month. The initial boost came from the company's impressive fiscal second-quarter 2025 results, which were reported near the start of June, and were subsequently compounded by an important product launch and a series of positive analyst takes on the stock. During that period, Broadcom managed to grow its revenue by a robust 20% year over year to just over $15 billion -- a new quarterly record for the chipmaker. Better, its non-GAAP (adjusted) net income soared 44% higher to nearly $7.8 billion, or $1.58 per share. Although expectations were fairly high, with consensus analyst estimates sitting just below those figures, at $14.95 billion for revenue and $1.57 for per-share adjusted net income, investors ultimately traded up Broadcom stock on the news. There were other reasons to be satisfied, after all. Broadcom's rather sparse guidance called for roughly $15.8 billion in revenue for its current (third) quarter; like the trailing results, this is slightly ahead of the average pundit projection ($15.77 billion). Much of Broadcom's growth comes from its position as a prominent supplier of chips for artificial intelligence (AI) functionalities. This continues to be a white-hot segment of the tech industry, and the company said its AI-related revenue rose 46% in the second quarter to more than $4.4 billion. More growth is in store, most likely, as Broadcom forecasts this to rise to $5.1 billion in the third quarter. Accordingly, the company has clearly prioritized the segment. Also, in June, it launched the Tomahawk 6 switch, a product designed to handle the comparatively more intense resource requirements of AI. This specialized hardware manages data traffic flowing through a network. We don't yet have a solid indication of how the initial takeup of the Tomahawk was, but it's sure to have been strong. The rise of AI is relentless and unstoppable, so it's no surprise that Broadcom is a favored stock among investors and analysts alike. Some in the latter group of individuals were busy in June working up new takes on the company following that earnings report, and for the most part, these analyses were bullish. One of the more hopeful ones came from HSBC. The bank's Frank Lee upgraded his Broadcom recommendation from hold to buy and, in the process, more than doubled its price target to $400 per share from $240. Lee cited Broadcom's strength in the application-specific integrated circuit (ASIC) category, an important one for (again) AI, as a key factor in his move.

5 Best Artificial Intelligence Stocks to Buy in July
Data center AI demand isn't slated to slow anytime soon. Cloud computing is a massive beneficiary of rising AI workloads. 10 stocks we like better than Nvidia › Artificial intelligence (AI) investing remains in full swing, even halfway through 2025. Record data center spending has been announced, and all the major tech companies are following through with their plans, with some even expanding them. This bodes well for many players in the space and makes multiple companies excellent investments right now. I've identified five companies that appear to be excellent buys in the AI arena, which I can categorize into two main areas: infrastructure and cloud computing. Both are well positioned to benefit from the massive demand for AI right now, a key part of my investment criteria. Companies that fall under the AI infrastructure investment umbrella are Nvidia (NASDAQ: NVDA), Broadcom (NASDAQ: AVGO), and Taiwan Semiconductor Manufacturing (NYSE: TSM). Their products are currently being used to facilitate AI training and inference, and are key beneficiaries of massive AI spending. Nvidia needs no introduction, as its graphics processing units (GPUs) have powered the AI revolution from the start. There's no true competition in this space; only alternatives exist to prevent Nvidia from achieving outright market dominance. This bodes well for the future, as larger and larger data centers are being announced with Nvidia GPUs filling them. One area where Broadcom may be able to displace Nvidia's GPUs is with its custom AI accelerators, which Broadcom refers to as XPUs. XPUs can be configured to outperform GPUs when the workload they are fed is properly set up. By optimizing an XPU for a particular workload, Broadcom and its AI hyperscaler partners can create a more cost-effective and powerful computing device, albeit at the expense of flexibility. AI hyperscalers are increasingly utilizing more XPUs to train and run inference for AI models, but Nvidia GPUs remain at the center of many data centers due to their flexibility. There is plenty of room for both in the ongoing AI arms race, and each has a bright future ahead. Both Broadcom and Nvidia utilize Taiwan Semiconductor (TSMC) chips in their devices. This should come as no surprise, as TSMC offers clients the most advanced chip technology alongside excellent yields. As the demand for AI chips grows, that demand will trickle down to TSMC. This growth is fueling management's overall guidance for the next five years, which projects a compound annual growth rate (CAGR) of 45% for AI-related chips, with overall revenue expected to grow at a 20% CAGR. There is huge demand for AI hardware, and these three companies are well positioned to capitalize on it. But so are a few cloud computing providers. AI giants like Alphabet (NASDAQ: GOOG) (NASDAQ: GOOGL) and Amazon (NASDAQ: AMZN) aren't just building data centers for their internal AI use; they're also building them to rent out to others. Many companies may have AI aspirations, but they likely lack the resources to build a state-of-the-art AI training facility. Furthermore, they may not have a use case that requires running it all the time, which is necessary to justify the cost. Instead, companies can opt to rent computing power from cloud computing providers like Amazon Web Services (AWS) or Google Cloud. Furthermore, many companies are shifting non-AI workloads to the cloud and powering them with GPUs from providers like Nvidia. This demand is boosting the entire ecosystem, making stocks like Alphabet and Amazon excellent buys. Grand View Research estimates that the entire cloud computing market will reach about $750 billion by 2024. However, it's expected to explode higher and have a projected market size of $2.4 trillion by 2030. That's huge growth that every investor wants a piece of, and owning Amazon and Alphabet is a great way to capitalize on this trend.

AI and 5G Bestow Premium Price Tag on Broadcom Stock (AVGO)
Wall Street remains enamored with global semiconductor giant Broadcom (AVGO), as the stock reaches fresh all-time highs and, to many, creates a self-fulfilling prophecy. The trillion-dollar semiconductor giant is posting record revenues, fueled by surging demand for its AI chips, which in turn translates into further investor interest and increased exposure — a virtuous cycle as far as AVGO investors are concerned. Don't Miss TipRanks' Half-Year Sale Take advantage of TipRanks Premium at 50% off! Unlock powerful investing tools, advanced data, and expert analyst insights to help you invest with confidence. Make smarter investment decisions with TipRanks' Smart Investor Picks, delivered to your inbox every week. Broadcom's expanding footprint in AI infrastructure—alongside its key role in next-generation technologies like 5G—keeps me bullish on the stock, despite its lofty valuation, which has seen AVGO's P/E ratio balloon to 99.5. When compared to the IT sector mean of ~30, it's understandable why worries about AVGO's valuation would be surfacing. AI Semiconductor Growth Soars Broadcom's AI semiconductor business continues to demonstrate strong growth. In its fiscal second quarter of 2025, revenue from the company's Semiconductor Solutions segment increased 17% year-over-year, reaching $8.4 billion, marking nine consecutive quarters of growth in AI-related products. Within this segment, AI semiconductor revenue rose to $4.4 billion, and Broadcom anticipates this figure will grow to $5.1 billion in the fiscal third quarter. This performance reflects sustained demand from hyperscale customers, such as Meta Platforms (META), for Broadcom's custom application-specific integrated circuits (ASICs) and high-performance Ethernet-based networking solutions. In addition to top-line growth, Broadcom is also achieving improved profitability. Over the past two quarters, gross profit margins have increased to 78%, up from the low-to-mid 70% range observed in prior periods. This margin expansion is primarily driven by the integration of VMware, whose infrastructure software has supported Broadcom's transition to a subscription-based revenue model. Furthermore, the company's specialized and highly customizable ASICs provide meaningful pricing power, reinforcing Broadcom's competitive position in the AI infrastructure space. Broadcom's ASICs Represent AI's Nervous System For those less familiar, Broadcom has long held a leadership position in networking and connectivity technologies. Its application-specific integrated circuits (ASICs) play a critical role in optimizing the performance of large language models (LLMs) by enabling efficient and high-speed data transfer. While Nvidia's (NVDA) GPUs handle the intensive computational workloads, Broadcom's ASICs ensure the smooth and rapid movement of data to and from these AI accelerators. In essence, if Nvidia's GPUs are the 'brains' of AI processing, Broadcom's ASICs serve as the 'nervous system,' facilitating the seamless data flow required for peak performance. Without this foundational infrastructure, GPUs would be unable to operate at their full potential. Beyond its advancements in AI, Broadcom is also making notable strides in 5G technology. The company's chipsets, designed specifically for 5G infrastructure, support faster, more reliable wireless connectivity. Broadcom offers a comprehensive end-to-end portfolio of 5G mobile networking switches, built to address the performance and scalability requirements of 5G across the entire network. As global 5G adoption continues to accelerate, Broadcom is well-positioned to capitalize on this expanding market, which is projected to surpass $100 billion by 2032. Navigating Tariff Headwinds Broadcom has also benefited from favorable macroeconomic developments. In late May, the Trump administration announced a delay in the proposed 50% tariff on European Union goods. As the July 9 deadline approaches, reports suggest that the U.S. and EU are making progress toward a deal that could prevent the tariffs altogether. This is a significant development for Broadcom, whose chips are widely used in devices worldwide. Imposing tariffs on EU goods could lead to higher costs and weaker demand, potentially creating headwinds for the company. A resolution on this front would help mitigate that risk. Strong Financials, Premium Valuation Fortunately for Broadcom, its solid financial position provides a cushion against potential cost pressures. As TipRanks data shows, the company holds $9.47 billion in cash and short-term investments and has been steadily reducing its debt, giving it the financial flexibility to navigate rising expenses if needed. As is often the case with stocks carrying high earnings expectations, AVGO trades at a substantial premium. Its price-to-earnings (P/E) ratio stands at 99.5, well above the IT sector median of 29.38. To be fair, a portion of this premium appears justified: Broadcom is delivering exceptional revenue growth of 33.85% year-over-year, more than five times the sector median of 6.34%, mainly driven by demand for its AI chips. However, with such lofty expectations baked into the stock, any slowdown in growth could leave it vulnerable to a sharp correction. Is Broadcom a Buy, Sell, or Hold? On Wall Street, AVGO boasts a Strong Buy consensus rating, based on 27 Buy, two Hold, and zero Sell ratings over the past three months. AVGO's average stock price target of $293.80 implies an upside potential of ~7% over the next twelve months. Last month, Morgan Stanley analyst Joseph Moore assigned a Buy rating on AVGO stock with a price target of $270. He expressed optimism regarding Broadcom's growth potential in AI, noting that the 'anticipated acceleration in processor sales and the continued strength in networking are expected to drive future performance.' Meanwhile, Bank of America analyst Vivek Arya has upped the ante with a price target of $300 alongside his Buy rating. In addition to Broadcom's diverse product portfolio and potential in AI, the analyst lauded the company's 'blend of capital appreciation and consistent dividend growth.' Broadcom's AI Edge Brings High Expectations Wall Street's optimistic view on Broadcom (AVGO) appears well-founded. The company is capitalizing on strong macro tailwinds—particularly rising demand for AI—and continues to show solid improvements in its core business fundamentals. The recent delay in proposed EU tariffs has further lifted investor sentiment, helping propel the stock to all-time highs. Broadcom's longstanding leadership in networking technology also positions it as a key player in transformative areas like AI and 5G—an advantage that won't be easily replicated by competitors. That said, the stock carries its share of risk. Its elevated valuation—reflected in a P/E ratio approaching 100—assumes a high level of continued success. Any unfavorable developments on the trade front, particularly around EU tariffs, could weigh on the stock. Additionally, if demand for AI infrastructure were to slow, Broadcom's growth trajectory could face meaningful pressure. Overall, given Broadcom's critical role in powering AI infrastructure and its diversified technology portfolio, I remain bullish on AVGO.
