The S&P 500 trades at a Shiller CAPE ratio of 41, and the article argues that risks to the bull market are mounting after the Fed hiked rates and September CPI inflation reached 3.7%. It contends that Interactive Brokers (IBKR) could benefit from periods of heightened volatility. The brokerage reported a record 5.58 million client accounts at the end of the third quarter, up 35% year over year, while margin loan balances rose 36% to $105.2B. Third-quarter revenue reached $1.91B, up 15%, led by a 19% rise in net interest income to $1.15B and a 12% rise in commission revenue to $602 million. The stock trades at a trailing P/E of 31.6 versus 23.5 for the S&P 500, while Wall Street's average estimate of $3.31 in 2027 earnings per share implies a forward P/E of 24.9.

- If a Bear Market Is Coming , This Unstoppable Growth Stock Could be a Huge Winner
The S&P 500's Shiller CAPE ratio is 41, second only to the dot-com bubble peak, and the author notes rising risks to the bull market, including Fed rate hikes and turbulence in AI stocks. Interactive Brokers (IBKR) is presented as a likely beneficiary of volatility; it reported a record 5.58 million client accounts at the end of Q3, up 35%, with client equity up 27% to $964.7 billion and margin loans up 36% to $105.2 billion. Q3 revenue rose 15% to $1.91 billion, led by net interest income of $1.15 billion (up 19%) and commissions of $602 million (up 12%). The stock trades at a P/E of 31.6, above the S&P 500's 23.5, but at 24.9 times the $3.31 per-share 2027 estimate, which the author argues could make it look cheaper.
- The Federal Reserve Just Warned More Rate Hikes Are Likely Coming. History Has Good and Bad News for Investors
The S&P 500 has climbed roughly 100% since the start of 2023, driven by enthusiasm for AI and growth stocks, but oil-driven inflation has become a headwind. The Fed raised its federal funds rate by a quarter point to 3.75%–4% last month, its first hike in three years, and its minutes warned that another increase is likely. CME FedWatch shows a probability above 88% of a rate increase at the December meeting. The article notes that higher rates can pressure corporate earnings and consumer spending, but history shows the index has typically recovered and gained afterward, and the author argues high-rate periods can present buying opportunities.
- Inflation Just Spooked the Market -- But There Still Good News for Patient Investors
September's CPI rose 0.6% month-over-month and 3.7% year-over-year, up from 0.4% and 3.4% in the previous report. The hotter data raised the odds of Federal Reserve rate hikes, and on that day the S&P 500 fell 1.1% and the Nasdaq 1.8%. October 14 was the 18th day in 2026 the S&P 500 fell more than 1%, which the author says is not unusual. To illustrate long-term results, the author notes $10,000 invested in an S&P 500 ETF in October 2006 would be worth $56,170 in share price alone, or $80,970 with dividends reinvested, versus $16,697 needed to match 2006 purchasing power.
- The Fed Is Fighting Inflation Again. History Says Trouble, but This Time Might Be Different.
The Fed raised interest rates in September for the first time since 2023, and the market is pricing in several more hikes in 2027. The labor market added just 29,000 jobs last month, while headline inflation rose 0.6% month over month to an annualized 3.7%, making near-term easing unlikely. The article compares three periods of restrictive policy and slowing growth: 2000–2001, 2006, and 2022–2023. The tech bubble and the financial crisis that followed 2006 ended in significant bear markets, while in 2022–2023 inflation fell without a lasting recession. The author says a significant correction is a real possibility, but expected Q3 earnings growth above 20% year over year and the S&P 500's roughly 21 times forward earnings make the picture more balanced.
- The Stock Market is Flashing Several Warning Signs at Once. Does That Mean a Crash is Imminent?
The article highlights three warning signs at once: the CAPE ratio at 40.5, the second-highest reading in 150 years; the Federal Reserve's first rate hikes in years; and margin debt up 49% over the past year. It notes these are not perfect predictors, as the S&P 500 rose 10.9% over the 12 months after margin debt last surged in 2025. Instead of panicking, the author suggests building cash by selling lower-conviction holdings and creating a watch list for a possible downdraft. On Alphabet, the author says the stock at 26 times forward earnings is not cheap enough to add now, and would start buying more near $300 per share.
- Investors look to earnings to reset the bull market. The key level to watch on the S&P 500
The S&P 500 remains in an uptrend but is chopping around a flat 50-day moving average, a level first reached 11 weeks ago. AI-hardware stocks have sold off sharply, bank shares are trading poorly after results, credit markets are under strain, and the Nasdaq has retreated 5%. JP Morgan's Jason Hunter leans cautious, saying a further drop of about 2.5% to 7500 would cost the market the benefit of the doubt. The article recalls 2018, when the S&P 500 fell 19% in the fourth quarter of a midterm year even as earnings grew more than 20%, while tightening now comes from higher Treasury yields, wider credit spreads and a stronger dollar. Bank of America's Aditya Bhave maintains a non-consensus call for an October Fed rate hike, while Morgan Stanley's Mike Wilson argues Chairman Warsh should acknowledge the tightening.

- Amazon (AMZN): Can Custom AI Silicon Outpace Capex Commitments?
Amazon opened its Trainium AI chips to every PyTorch developer, letting engineers run existing code on its own hardware without rewriting it. The chips business is selling at an annual pace above $25 billion, and AWS sales grew 37% in the second quarter, up from 17% a year earlier, while CEO Andy Jassy said the AI business has also passed a $25 billion annual run rate. Anthropic and OpenAI have made multi-year commitments to Trainium. However, AI-related spending pushed free cash flow to an outflow of $7.6 billion over the past 12 months, versus an inflow of $18.2 billion a year earlier, and long-term debt rose to $128.9 billion from $65.6 billion at the end of last year. Second-quarter operating income rose 43% to $27.5 billion, but the article says the stock now depends on AWS demand lasting long enough for cash flow to recover.
- Anthropic Has Locked In Over $600 Billion of Computing, More Than Intel Is Worth. It Still Wants More and That’s Big News for AMD.
Ahead of its IPO, Anthropic has committed more than $600 billion to computing, more than Intel's $484.7 billion market value, according to leaked reports of its S-1 filing. The article cites three different totals: $518 billion of signed commitments (Reuters, late September), above $600 billion (Crypto Briefing), and a possible $750 billion of extra computing spending over several years (Wall Street Journal). Anthropic reportedly brought in $16.3 billion of revenue in the first half of 2026 but posted an $80.7 billion net loss, mostly from accounting charges. AMD said Anthropic will deploy up to 2 gigawatts of its MI450 GPUs starting in the first half of 2027, and AMD's second-quarter revenue rose 50.1% to $11.54 billion, with Data Center revenue up 107% to $6.72 billion. The article says the risks center on Anthropic's hard-to-cancel commitments, its losses and its dependence on an IPO, and notes AMD trades at a P/E of 201.
- AI bottlenecks 'keep shifting': Nvidia CEO Jensen Huang explains
Nvidia CEO Jensen Huang, speaking with Deirdre Bosa at Nvidia GTC Berlin, said AI bottlenecks keep shifting, moving from wafers to CoWoS, HBM memory, silicon photonics and connectors, and now to power. He said power is often available, but land, power shells, generator delivery, grid connections and construction limits create the problem, and permitting rules differ across countries and states. Huang argued Nvidia is resilient because it supports every AI model, cloud provider and computer company across every country, so it can ship chips wherever a bottleneck is resolved. He expected these physical bottlenecks to persist for a couple more years as AI factories ramp up.
- Nvidia (NVDA) Is Trading Like Growth Will Stop. The Numbers Say Otherwise.
A hotter-than-expected inflation report pushed Nvidia down more than 3% in one session, as investors worried about interest rate hikes that would raise borrowing costs for companies building AI data centers. Fiscal second-quarter revenue still reached $96.2 billion, up 106%, with data center sales up 117%, and the company guided fiscal third-quarter revenue to $108.0 billion, plus or minus 2%, excluding data center compute sales to China. Gross margin was 75.0% in the quarter. The article's main question is whether Nvidia's customers can keep paying for chips, pointing to CoreWeave's sharp drop after its bond yield chart spread online and the doubts it raised about its heavy debt. Nvidia has announced financing partnerships with Apollo, BlackRock, Blackstone, Brookfield, Goldman Sachs and KKR aimed at bringing more than $500 billion of outside capital into AI infrastructure over time, though definitive agreements are still needed.
- Bitcoin price tags $84.6K as US stocks head higher on SpaceX Q3 earnings beat
Bitcoin rose nearly 2% to $84,600, its first time at that level since Oct. 7, as US stocks gained after SpaceX reported third-quarter revenue of $14.6 billion, up 161% year over year and beating expectations by nearly 15%. SpaceX also posted net income of $4.4 billion, and analysts at Truist Securities said its results helped calm fears over corporate spending on AI buildouts. The tech-heavy Nasdaq Composite rose 0.7% early in the session before giving back some gains, while South Korea's KOSPI finished 3.29% higher at 5,735 points. Rekt Capital said Bitcoin needed a daily close above $83,400 to shift focus higher, and that a rejection there could send price below $82,500.
- Bybit will look for big broker partnerships to take on Robinhood in the U.S.
Bybit CEO Ben Zhou said the exchange plans to enter the U.S. through a partnership with an established local firm, such as Interactive Brokers, rather than pursue state-by-state licenses that could take two to three years. He noted Bybit, which has over 80 million registered users in more than 180 countries and regions, has a clean U.S. record and would wait for the Clarity Act or a clearer federal regulator before moving rather than rushing in. Zhou described the U.S. as competitive and saturated, and pointed to the U.K. as a relatively untapped market with a new crypto regime and no dominant global exchange, though entry costs are very high. Bybit also plans to launch an everything app offering derivatives and tokenized stocks in Europe as early as the first quarter of next year.
