The S&P 500 has more than doubled over the past four years and is up 11% year to date, but is roughly flat over the past month amid concerns about artificial intelligence (AI) spending and high oil prices. The article points to three indicators: the Buffett indicator now stands at 301%, while Buffett has said a reading above 200%, as before the 2000 crash, means investors are 'playing with fire.' The average CAPE ratio is 17.8, and it has surpassed 40 only twice, once before the 2000 dot-com crash and now. Persistent inflation could lead to further interest rate hikes, making it harder for companies to borrow and grow, and making bonds more attractive relative to stocks. The author stresses that a crash is not certain, as the Federal Reserve could tame inflation before one occurs.

- Warren Buffett's Latest Warning Is Sending Shockwaves Through Wall Street. Here's What History Says Could Happen Next.
Warren Buffett's Berkshire Hathaway portfolio has returned an average compound annual 19.7% over six decades, versus 10.5% for the S&P 500, and he has recently warned about a 'gambling mood' in the stock market and high equity prices. The S&P 500's CAPE ratio stands at 40.7, far above its average of 17.4 and exceeded only during the dot-com bubble, when it peaked at 44 in late 1999. In his final meeting as Berkshire CEO in May 2025, Buffett warned that the US fiscal deficit was unsustainable; the article argues the situation has since worsened, with Brent crude up 80% since the start of the year and September inflation at 3.7%, well above the Fed's 2% target. Higher inflation erodes the value of cash and keeps interest rates high, which could be particularly harmful for the AI industry. The article recalls Buffett's 2021 advice to 'never bet against America' and suggests that time in the market usually beats trying to time it.
- What Up w / Stocks , Cryptos , Gold & Silver ? October 19th , 2026 | Vero Patriot
The S&P 500 and Nasdaq posted their worst weekly performance since June, and many AI-linked companies entered bear market territory with declines of 20% or more. Hotter-than-expected inflation, with CPI at 3.7% and PPI at 6.2%, led investors to price in at least an 89% chance of another Fed rate hike this year, though most still expect no change at this month's meeting. WTI crude closed above $101 per barrel, while the 9% of companies that had reported third-quarter earnings averaged 29% growth. Year to date, the Dow is up 7%, the S&P 500 12% and the Nasdaq 13%, while Bitcoin is down 8%, Ether 19%, gold 3% and silver 19%. Based on earnings, the article says the S&P 500's P/E of 26.12 versus a historical average of 16.24 implies a maximum downside of 38%.
- These 3 Big Risks Could Cause the Next Bear Market. I'm Investing Anyway.
The article argues that stocks always carry risk, pointing to the 2022 bear market when the S&P 500 fell about 18% and the Nasdaq-100 about 32% on a total return basis. The author outlines three risks: heavy reliance on AI, as Goldman Sachs research from September found the largest AI hyperscalers had spent about $800 billion in capital expenditures since the start of the year; rising rates, as the Fed hiked in September and the 10-year Treasury yield has risen about 0.92% over the past year; and high valuations, with the CAPE ratio at levels not seen since 2000, just before the dot-com crash. Even so, the author says they will keep investing and buying more stocks through low-cost index funds, noting the S&P 500 has averaged 9.98% annual returns since 1928 and the Vanguard S&P 500 ETF (VOO) about 13.8% a year over the past five years, including 2022.
- If a Stock Market Crash Is Coming, History Suggests These Are 2 Crucial Moves to Make.
The article notes the S&P 500 has gained 100% since the start of 2023, driven by investor enthusiasm for AI stocks such as Nvidia, Micron Technology and Microsoft, but worries are growing about AI overspending, higher interest rates and near-record valuations. Although the Federal Reserve held rates steady at its latest meeting, CME Group’s FedWatch tool puts the probability of a rate hike at the December meeting at 83%. The article argues that market crashes are a normal part of the cycle, so preparing early makes sense, and suggests two steps: taking a long-term view with holdings of at least five years, and buying quality stocks at reasonable or low prices during downturns.
- Prediction: This Magnificent ETF Will Crush the S&P 500 Over the Next 10 Years
Some leading investment strategists see a sluggish period ahead for the S&P 500, citing higher-for-longer interest rates and overvalued large caps, with a 10-year CAPE ratio above 40, the highest since the dot-com boom. The author argues the iShares Global Equity Factor ETF (GLOF) could beat the S&P 500 over the next decade: it is a global fund with 61% in U.S. stocks and 7% in Japan, holding stocks with the highest scores on momentum, quality, value, low volatility and size. The fund holds 684 stocks, with Apple, Nvidia and Microsoft as its largest positions. Over the past 10 years its annualized total return was 12% versus 15.4% for the S&P 500, but over the past one and three years it has outperformed: 15.8% vs 13.5%, and 24.1% vs 23.7%.

- Why Micron Stock Looks Cheap After a Record Year
Micron, which makes memory chips for PCs and AI servers, posted a record fiscal 2026 with revenue of $133 billion and adjusted earnings of $75.52 per share, up from $8.29 a year earlier. Yet the stock closed on Oct. 28 about 13% below its earnings-day close, trading at a forward P/E of about 5.5 versus about 19 for the S&P 500. Micron has signed 26 long-term strategic customer agreements covering over 35% of expected revenue through 2030, backed by $32 billion in customer financial commitments. Adjusted free cash flow reached $62 billion for the full year, while capital spending of about $27 billion in fiscal 2026 and about $25 billion planned for the first half of fiscal 2027 will fund new supply. The article says DRAM prices and days of inventory are the two metrics to watch: if prices keep climbing and inventory days fall as management expects, the stock could keep surging next year; if inventory keeps rising while prices stall, that signals excess supply.
- Novo Nordisk Trades at 10 Times Earnings While Buying Back Billions in Stock. Is This the Bottom?
Novo Nordisk shares have fallen roughly 70% from their 2024 high and now sit below their mid-2021 level, leaving a P/E of about 10x versus a five-year average of nearly 24x. The article attributes the slump to Eli Lilly's more effective GLP-1 drugs and Novo's supply shortfalls, which let generics enter the U.S. market early. Novo is shifting toward a high-volume, low-cost model, a change that is weighing on current results but could be offset if demand meets expectations. The company has launched a $2.2 billion share repurchase program and offers a 4.6% yield with a 33% payout ratio. The article argues the market may be overly pessimistic, though the transition will take time.
- Social Security may have to cut retirement benefits in six years. Here's how much money is at stake for beneficiaries
Social Security retirement benefits could face an automatic cut of about 22% in the fourth quarter of 2032, when the trust fund is projected to run out, according to the trustees; the Congressional Budget Office forecasts an earlier depletion in mid-2032 with a 26% cut. The Committee for a Responsible Federal Budget estimates a 24% cut would reduce average monthly benefits by about $500 nationwide, with larger reductions in 29 states. Delay could push up Treasury yields and borrowing costs and weigh on economic growth; the National Institute on Retirement Security says Social Security generated $2.6 trillion in economic output and supported more than 12 million jobs in 2023. Economist Jessica Riedl calls a payroll tax increase in the next couple of years 'extraordinarily unlikely,' noting Washington tends to wait until the last minute.
- These Senate races may help determine the fate of Social Security
Senators elected in November must address Social Security before the trust fund is projected to run out in Q4 2032, when benefits could be cut by 22% without action. A Peter G. Peterson Foundation survey finds 81% of voters are more likely to back a candidate with a plan to avoid automatic cuts than one who promises not to touch the program. CNBC identified nine of the 35 Senate races where candidates have discussed the program's future, and MS NOW rates all nine as closely contested. In Alaska, Republican incumbent Dan Sullivan faces former Democratic Rep. Mary Peltola, who proposes eliminating taxes on Social Security benefits; MS NOW rates the race a toss-up. In Iowa, Democrat Josh Turek calls for removing the payroll tax cap, while Republican Ashley Hinson says she will reject any proposed cuts, though a local field office in her district closed for six months.
- Social Security's Trump Bump-Powered 2027 COLA Is the 5th Largest in 35 Years, but It Comes at a Potentially Steep Cost
The Social Security Administration announced a 3.6% cost-of-living adjustment (COLA) for 2027 on October 14, after the September inflation report, the fifth-largest increase in 35 years. The average retired-worker benefit is expected to rise by $75 a month, and this marks the sixth straight year of increases of at least 2.5%. The article attributes part of the bump to inflation driven by President Trump's policies, including tariffs and the Iran war, which has kept the Strait of Hormuz closed for eight months and counting. However, it warns the outsize raise could worsen the program's finances, citing a $29.3 trillion long-term unfunded obligation and an expected depletion of the OASI trust fund's reserves by the fourth quarter of 2032.
