SpaceX's quarterly capital expenditures of $18.4 billion raise questions about investor returns, but the spending is primarily directed toward AI infrastructure ($15.8 billion) and other growth initiatives. With 247% year-over-year AI revenue growth and payback periods under a year, the investments appear justified for now. However, investors should monitor whether SpaceX can maintain attractive returns as competition in data center infrastructure intensifies and the company's $1.9 trillion valuation leaves little room for mediocre returns.

Nebius and CoreWeave are neocloud infrastructure companies benefiting from surging AI data center demand, with the market expected to grow at a 58% CAGR through 2031. Nebius has outperformed with 146% gains in 2026 and improving profitability, while CoreWeave trades cheaper but faces higher losses despite a stronger revenue backlog of $104 billion. Both stocks offer long-term growth potential depending on investor risk profile.

A new Anaqua report analyzing 713,755 semiconductor patents reveals AI-related semiconductor patents grew 114% over five years, nearly double the 78% growth of overall semiconductor patents. The analysis shows AI is now the primary driver of semiconductor innovation across chip architecture, GPUs, and inference processors, with major players like Samsung, IBM, Intel, and Chinese entities leading in different AI-chip categories, while hyperscalers like Google and Microsoft increasingly design custom chips.

With the S&P 500 trading at historically high valuations (CAPE ratio of 41.8), the article identifies SpaceX and Datadog as two growth stocks that could be vulnerable to sharp corrections if market turmoil occurs. SpaceX trades at a P/S ratio of 83 despite strong AI business potential, while Datadog's P/S ratio of 21.8 is elevated compared to peers, making both susceptible to downside risk in a market downturn.

Billionaire Stanley Druckenmiller's Duquesne Family Office sold 23,400 shares of Micron Technology in Q2 after the stock nearly quadrupled, citing profit-taking on the cyclical memory and storage stock. Simultaneously, Druckenmiller repurchased 336,300 shares of Alphabet, betting on the company's explosive AI growth, particularly Google Cloud's 82% year-over-year sales growth driven by generative AI capabilities.

During the July-August 2026 U.S. tech earnings season, MEXC data shows storage and memory stocks dominated trading activity at 67.3%, with SK Hynix and Samsung earnings reports triggering significant volume spikes across related assets.

Greg Abel, who took over as CEO of Berkshire Hathaway on December 31, has made significant portfolio changes in his first year. He has systematically reduced Bank of America holdings over eight consecutive quarters (down 53% cumulatively) due to valuation concerns and interest rate sensitivity. Simultaneously, Abel has aggressively increased Alphabet (Google) holdings to $17 billion in Q2, making it Berkshire's third-largest position, driven by the company's dominant search market share and strong AI growth potential in Google Cloud.

A $5,000 investment in the Vanguard S&P 500 ETF (VOO) a decade ago would have grown to nearly $21,000, representing 15.4% average annual returns. However, the article cautions that historical S&P 500 returns average around 10% annually, and investors should not expect similar performance going forward. Despite potential market corrections, long-term investors who maintain their positions for 5-10+ years have historically seen the market recover and reach new highs.

Jensen Huang's June recommendation to buy Nvidia during a market pullback resulted in a 4% gain over three months, matching S&P 500 returns. However, a diversified AI basket of Nvidia, Microsoft, Amazon, and Alphabet gained 8%, driven primarily by Microsoft's 24% surge. The article argues that three months is too short to evaluate long-term investments, and Nvidia's strong 106% year-over-year revenue growth and 17.5x P/E ratio (below its 23x five-year average) suggest Huang's optimism may still be justified for long-term investors.

Broadcom is set to report Q3 earnings on Sept. 2 with management guidance projecting $16 billion in AI semiconductor revenue with over 200% year-over-year growth. While the company has shown strong momentum with Q2 revenue up 48% and AI chip revenue up 143%, investor concerns persist over Alphabet's expanded partnership with Marvell Technology for custom AI chips. Broadcom's stock performance has lagged the S&P 500 this year, but hitting the $16 billion target could ease concerns and present a buying opportunity.

Berkshire Hathaway recently resumed stock buying after years of net selling, holding $359 billion in cash. The article suggests Walt Disney could be an attractive value investment with a forward P/E of 14.3 and strong intellectual property moat. However, the author believes Berkshire is unlikely to buy Disney shares due to concerns about declining legacy TV operations and intense streaming competition.

Waymo, Alphabet's autonomous vehicle subsidiary, has reached a $126 billion private valuation and is conducting over 500,000 weekly autonomous rides, suggesting real commercial scale. However, the investment upside for Alphabet shareholders depends on whether zero-driver economics improve as the network expands, representing a potentially significant but uncertain growth opportunity.
