Citadel CEO Ken Griffin said at a conference on Oct. 20 that the AI boom is "almost certainly" showing bubble-like behavior, though he views this as not necessarily negative while companies are still experimenting. He said U.S. corporations have been "uneven" in their ability to extract value from AI models, with leaders now reviewing their bills from Anthropic and OpenAI; if firms cut AI spending, that could weigh on AI stocks in the short run. Over the long term, Griffin is bullish, comparing AI to railroads, electrification and the internet in its potential for major economic gains, though the eventual winners remain unclear. He did not name specific stocks, but the article notes two approaches: picking individual AI companies or owning a broad tech ETF such as the Invesco Nasdaq-100 ETF (QQQM), which charges a 0.15% expense ratio and has returned about 20.9% year to date and about 16.4% annualized over five years.

The tech-heavy Nasdaq gained after quarterly results from SpaceX and Super Micro Computer improved appetite for AI-linked stocks, while Netflix slipped after a weaker-than-expected fourth-quarter forecast.

- Hedge Fund Stock Pickers Lost 2 . 9 % in a Week as AI Trades Unwound , Goldman Sachs Data Showed :
Global fundamental long-short hedge funds lost money every day in the week to Oct. 15, ending down 2.9%, though they remain up 14.3% year to date, according to Goldman Sachs prime brokerage data. Asia-focused stock pickers were hit hardest, down 6.8% in the first half of October and erasing more than half of their gains since a late-June peak. Goldman said the selling was mainly long liquidation rather than new shorts, with hedge funds net selling its Global AI Basket for six straight sessions by Friday, reversing net buying since early last year. South Korea's KOSPI fell more than 7% on Oct. 15 and Taiwanese stocks dropped more than 3%. The strategy's one-day loss exceeded 80 basis points three times in 2026 (Feb. 4, July 28 and Oct. 15), after never doing so from Covid through the end of 2025, with a hotter-than-expected US inflation reading as the trigger.

- Joby Just Dropped 27% in a Month: Did JOBY Stock Just Find a Bottom?
Joby Aviation stock is down 0.4% to $4.68 in the afternoon session, extending a 27% monthly slide. Archer Aviation fell 32% over the past month to $3.87 and EHang dropped 29% to $3.35, suggesting sector-wide pressure on air taxi stocks. Over the same period, the ARK Autonomous Technology & Robotics ETF lost 11% and SPY fell 2%. Joby and Archer both need FAA certification before carrying paying passengers in the U.S., so regulatory progress or setbacks could affect both. The article argues one muted session is not enough to confirm a bottom, and says the next test is whether Joby reaches its next certification milestone.
- Procter & Gamble Has Raised Its Dividend for 70 Straight Years. Here's Why That Matters in a Sell-Off
Procter & Gamble has raised its dividend for 70 consecutive years, making it a 'Dividend King' that has increased payouts for at least 50 straight years. Its 2.6% forward yield looks modest next to the 5% yield on the 10-Year Treasury, but P&G's total return with dividends reinvested was nearly 150% over 10 years and 1,310% over 30 years. The article credits its resilience to essential household and personal care products, after P&G cut its portfolio from around 180 brands in 2014 to 65, focusing on roughly 20 that generate over $1 billion in annual sales. Free cash flow rose 8% to $15.1 billion in fiscal 2026, covering $10.2 billion in dividends, and P&G expects organic sales to grow 1%-3% in fiscal 2027. At $160, the stock trades at 23 times the midpoint of its fiscal 2027 core EPS forecast, a multiple the article calls a bit high relative to its growth potential.
