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.

- If a Bear Market Is Coming, This Unstoppable Growth Stock Could be a Huge Winner
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.
- 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 notes three warning signs flashing at once: the CAPE ratio at 40.5, its second-highest reading in 150 years; the Federal Reserve has just begun raising rates for the first time in three years; and margin debt has surged 49% over the past year. Per cited data, the S&P 500 declined in five of the last six Fed rate-hike cycles, and the market fell five out of six times when margin debt rose 45% or more year-over-year since 1960. However, these are not perfect predictors: CAPE was above 30 in 2018, yet the S&P 500 rose 29% the following year. The author suggests treating these signs as a reminder to prepare portfolios, such as building cash and a watch list of stocks to buy during a downturn, rather than panicking.

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.

- Trump to throw spotlight on overseas crypto abuses at White House event
President Donald Trump is set to highlight his administration's efforts to pursue overseas crypto criminals at a White House cybercrime event on Wednesday, according to an official. U.S. law enforcement has halted about $833 million in crypto tied to overseas scams, and 503 fraudulent crypto websites have been seized under the Homeland Security Task Force. Authorities have also informed almost 9,000 U.S. citizens that they are being victimized. The transnational criminal organizations behind these scams have stolen tens of billions of dollars from Americans, and the Treasury formed a multi-agency Scam Center Strike Force in November. Meanwhile, Trump's personal crypto ties may have become a political liability as the midterm elections approach in a couple of weeks.

- Musk's SpaceX-Tesla Merger Would Create a Bitcoin Treasury Behemoth
Elon Musk said the boards of SpaceX and Tesla have formed special committees of independent directors to weigh a merger, while cautioning that a deal is not a certainty. Combined, the two would hold 30,221 BTC, worth roughly $2.5 billion at a Bitcoin price near $83,000, making it one of the largest non-mining corporate Bitcoin treasuries. Tesla reported 11,509 BTC in its latest quarterly filing, while SpaceX disclosed 18,712 BTC in its S-1 ahead of its June IPO, a stash largely invisible to public markets and more than double previous blockchain-tracker estimates. The combined cost basis is around $1 billion, implying an average buy price near $35,000 per coin. A merger would not change Bitcoin itself but would alter governance and accounting, placing the holdings in one public company subject to quarterly disclosures; neither company has signaled plans to buy or sell.

- Chainlink, Cardano, other blockchain groups push SEC for clearer crypto rules
Six major blockchain organizations, including Chainlink Labs, Cardano Foundation, Hedera, Aptos Labs, Ava Labs and Stellar Development Foundation, urged the SEC in a joint letter dated Oct. 20 to formally classify digital commodities as non-securities. They argued that interpretive guidance alone leaves legal uncertainty, and that this classification should be written directly into the proposed Regulation Crypto Assets framework. The letter also asks for clarity on how securities laws apply to secondary-market transactions, as well as on staking and other activities tied to decentralized blockchain networks. The SEC's proposal, introduced in August, drew roughly 140 public comments over 60 days, and the consultation closed on Tuesday.
- Government to submit new resolution on wage policy to Central Committee
Deputy Prime Minister Phạm Thị Thanh Trà said during a group discussion on the afternoon of Oct. 21 on laws covering labor, employment and social insurance that the Government is drafting a proposal to report to the Political Bureau. The proposal is expected to go to the Central Committee at its Fifth Plenum to issue a new resolution on wage and social insurance policy, replacing Resolutions No. 27-NQ/TW and No. 28-NQ/TW. According to the Deputy Prime Minister, the current amendment to the Social Insurance Law mainly addresses immediate issues such as expanding coverage, while a more fundamental and comprehensive revision will follow the new resolution. For the Employment Law, the focus is cutting unnecessary licenses and reviewing rules on labor leasing, though simplifying procedures does not mean loosening management. Lawmakers also raised rules on depositing funds in joint-stock commercial banks with state capital, and the Government aims for safety, sustainability and timely payment of benefits.
