The S&P 500 Is Near an All-Time High but Trading at Its Lowest Valuation in a Year. Nvidia, Alphabet, and Amazon Help Explain Why.

Despite the S&P 500 reaching near all-time highs with 13.1% year-to-date gains, the index trades at its lowest valuation in a year with a forward P/E of 19.4. Major growth stocks like Nvidia, Alphabet, and Amazon have become cheaper based on forward earnings ratios because their earnings growth is outpacing stock price increases. These companies are investing heavily in AI infrastructure, which could lead to significant margin expansion once their capital investments begin generating returns.

Warren Buffett's Successor, Greg Abel, Jettisoned Amazon Earlier This Year and More Than 6X'd Berkshire's Stake in the "Apple" of His Eye

Greg Abel, Warren Buffett's successor as Berkshire Hathaway CEO, has significantly reshuffled the company's $358 billion investment portfolio. Abel sold off Amazon stock in Q1 2026, likely due to profit-taking and the departure of investment manager Todd Combs. Meanwhile, Abel has dramatically increased Berkshire's stake in Alphabet (Google parent) from $5.59 billion to $36.37 billion between December 2025 and September 2026, a 550% increase, citing the company's dominant search market position, YouTube strength, and promising AI ambitions in Google Cloud.

Amazon Stock Pays $0 in Dividends. Here's Why Long-Term Investors Should Own It Anyway.

Amazon continues to forgo dividend payments despite reaching maturity, instead investing heavily in AI infrastructure and data centers ($220 billion in 2026). The article argues this strategy benefits long-term investors through tax-efficient capital appreciation and strong growth, particularly in AWS which grew 33% and generates 60% of operating income. The company's 251,000% lifetime return demonstrates the effectiveness of reinvesting capital rather than paying dividends.

Anthropic Plans to Spend $518 Billion on Cloud and Data Centers. More Than $100 Billion Is Already Promised to Amazon.

Anthropic's draft IPO prospectus reveals $518 billion in planned cloud and infrastructure spending over coming years, with $110 billion committed to Amazon Web Services through 2036. Despite large operating losses, Anthropic's revenue is growing rapidly (14-fold year-over-year in Q2 2026), making the AWS commitment appear manageable. However, concentration risk exists as nearly 25% of 2025 revenue came from just two customers without long-term contracts.

Warren Buffett's Record: $1,000 Became About $61 Million. Can Greg Abel Keep Compounding It?

Warren Buffett stepped down as Berkshire Hathaway chairman in September 2026, ending an era of exceptional returns (6,099,294% since 1965). New CEO Greg Abel faces the challenge of maintaining growth, but Berkshire's massive $1.1 trillion size makes repeating historical 19.7% annual returns virtually impossible. The company has underperformed the S&P 500 over the past decade and is sitting on $365.6 billion in cash while making strategic portfolio shifts.

Oracle Stock Is Down 60% From Its High. Here's Why I'm Still Not Buying.

Oracle's cloud infrastructure business is booming with 121% revenue growth and a $664 billion backlog, but the company faces significant financial risks. Its $95 billion annual capex spending far exceeds its negative free cash flow of -$5.4 billion, forcing the company to rely heavily on debt ($125 billion) and lease commitments ($288 billion). Unlike other tech megacaps, Oracle's precarious financial position makes it vulnerable if the AI boom slows.

Better AI Chip Stock to Buy Today: Broadcom vs. Marvell

Broadcom and Marvell are both leaders in custom AI chip design and data center networking, benefiting from the AI infrastructure build-out wave. While Marvell stock has outperformed significantly this year (up 200% vs. Broadcom's 3%), Broadcom is recommended as the better buy due to its market leadership in AI ASIC design (60% projected market share), premium customer base including Alphabet and Anthropic, and significantly cheaper valuation (P/E of 11.5x vs. Marvell's 25x for comparable periods).

Despite historical parallels and elevated valuations, long-term investors are advised to stay invested as the market has recovered from past downturns.
