#股票交易分享挑战 Five High-Quality U.S. Stocks Heavily Accumulated by Wall Street in Q2! A Breakdown of the Logic and Guide to the Best Entry Points.

As Wall Street institutions gradually disclose their quarterly 13F holdings filings, the portfolio adjustments made by top investment banks and hedge funds in Q2 have finally come to light.
Against a backdrop of macro volatility and the AI gold rush, Wall Street heavyweights are using real money to aggressively buy and accumulate core U.S. stock assets. Today, we take an in-depth look at the 5 high-quality U.S. stocks heavily accumulated by Wall Street in Q2, analyze the underlying investment logic, and provide practical recommendations for buying and adding to positions.

I. Google (Alphabet): Berkshire Hathaway Adds $10 Billion in a Single Quarter
1. Institutional Buying Logic
Buffett’s heavy accumulation: After beginning to build a position in Google at the end of last year, Berkshire Hathaway continued increasing its holdings. In Q2, it spent approximately $10 billion to aggressively add to its position, making Google one of its top five holdings.
Three business growth drivers: Google Cloud is growing strongly, its digital advertising core has stabilized and begun recovering, and the company has made large-scale capital expenditures on enterprise-level AI infrastructure.
Hidden major asset: Google holds as much as 95% of the investment portfolio stake in SpaceX. For investors who are bullish on SpaceX’s prospects but wary of its high volatility after listing, elevated valuation, and lack of fundamental support, buying Google is equivalent to indirectly holding SpaceX shares and is a very stable alternative.
2. Investment Recommendations and Bottom-Fishing Levels
Institutional cost: Berkshire privately purchased GOOG shares through a negotiated transaction in June at an estimated cost of approximately $348.20.
Suggested entry levels: Opening position: Around $335
Adding to position: Around $320
II. Amazon (Amazon): AWS Growth Reaccelerates as Macro Funds Rush to Accumulate
1. Institutional Buying LogicLarge macro hedge funds and multi-strategy institutions, including Bridgewater, significantly increased their Amazon holdings in Q2. The core driver was the renewed acceleration in AWS revenue growth. Improved regional fulfillment efficiency drove expansion in overall operating margins, while Amazon Prime Video and advertising provided strong cash-flow support. Although Amazon raised its full-year 2026 AI capital expenditure budget, Wall Street did not suppress the stock price as usual, and strong results supported a surge in the share price.
2. Valuation Comparison and Investment Recommendations
Valuation assessment: The current trailing P/E is approximately 21, while the forward P/E is approximately 28.76 (by comparison, Google’s forward P/E is only 25, giving it a slightly better valuation profile than Amazon).
Suggested entry levels:
Opening position: Below the strong support level of $255
Adding to position: Around $239, near the lower edge of the gap
III. TSMC (TSM): The Leading “Shovel Stock” in the AI Gold Rush
1. Institutional Buying Logic
An irreplaceable moat: If AI is a huge gold mine, and NVIDIA and AMD are companies designing the “shovels” for digging gold, then TSMC is the only major foundry truly capable of producing those shovels. From NVIDIA and AMD GPUs to Apple’s in-house chips, Broadcom’s ASICs, and Google’s TPUs, all ultimately depend on TSMC’s foundry services. Aside from geopolitical factors, its technological and monopoly barriers are impeccable.
2. Industry Valuation Comparison (Five Major Chip Stocks)Among the leading chip stocks, TSMC’s forward P/E is approximately 25.19, placing it at a relatively reasonable and low valuation:
Lower-valuation group: NVIDIA, TSMC
Mid-range valuation group: Broadcom
Higher-valuation group: AMD, Intel
3. Suggested Entry Levels
Opening position: Around $420
Adding to position: Around $396
IV. Micron Technology (MU): Benefiting from Both the Memory and Chip Trends, with Highly Attractive Valuation
1. Institutional Buying Logic
Wall Street institutions built large positions in Micron in Q2, mainly at the lows in April and May. Micron benefits from both of the hottest trends in the semiconductor chip and memory-demand sectors. In terms of valuation metrics, Micron’s current forward P/E is only 6.34, making its forward valuation highly attractive.2. Risk Warning and Strategy Adjustments
Cyclical characteristics: The memory sector is highly cyclical, so Wall Street generally assigns it a lower valuation premium.
Avoid chasing highs: Even a good stock can leave investors trapped if purchased at the top after chasing a rally. Investors should follow the principle of “buying on dips and building positions at a discount.”
3. Suggested Entry Levels
Opening position: Raised to around $896 (the round-number level below $900 can be used as a reference)
Adding to position: Around $820
V. Broadcom (AVGO): The Absolute Leader in Custom AI Chips (ASICs)
1. Institutional Buying LogicThe core logic behind institutional accumulation is the extremely strong demand for custom AI accelerators (ASICs) and network switches, along with the steady cash-flow contribution generated after the successful integration of VMware.
Technology outlook: AI chips are currently divided into traditional GPUs (led by NVIDIA and AMD) and customized ASIC chips (led by Broadcom). As major companies place greater emphasis on cost and efficiency, ASICs are expected to surpass traditional GPUs in market share and growth rate in the future.
2. Suggested Entry Levels
Opening position: Around $392, near the lower edge of the gap
Adding to position: Around $370, at the strong support level

Summary and Investment Mindset
Understanding Wall Street’s holdings reports is by no means about blindly following institutions and “becoming exit liquidity” at elevated levels. Rather, it is about using institutional perspectives to identify high-quality companies capable of weathering cycles. The core of investing is always to identify fundamentally strong leaders, patiently wait for their share prices to pull back and trade at a discount, and then buy in batches on weakness.
