Signal and Noise
New York, September 17, 2026, 8:48 a.m. ET. The Federal Reserve raised its main interest rate by a quarter point yesterday, its first increase since 2023, yet stocks point sharply higher this morning. The market hates an unanswered question more than a tough answer. S&P 500 futures, contracts pointing to the likely open, rose 1.22%, while Nasdaq 100 futures gained 1.59% at 8:40 a.m. ET. August retail sales then beat forecasts. Busy-person translation: today starts with relief, not safety.
Yesterday's Scoreboard
- S&P 500: 7,551.81, down 0.45%. The broad market slipped after the Fed raised rates and flagged hot inflation. (Yahoo Finance, September 16 close.)
- Dow Jones: 51,461.90, down 1.21%. Higher borrowing costs hit economy-sensitive companies hardest. (Yahoo Finance.)
- Nasdaq Composite: 25,978.43, down 0.01%. Technology stocks held flat while the Dow lost more than 600 points. (Nasdaq and Yahoo Finance.)
- Best major mover: Lumentum Holdings (LITE), $919.40, up 9.59%. AI demand lifted makers of gear that moves data between computers. (Yahoo Finance and CNBC.)
- Worst major mover: Diamondback Energy (FANG), $194.54, down 8.03%. Oil fell, an analyst downgrade landed, and an insider sale added weight. Three anvils, one stock. (Yahoo Finance and Google News.)
The Signal
- The Fed moved its target rate to 3.75% to 4.00%. That rate influences mortgages, loans, and what investors pay for future profits. Officials projected 4.1% for year-end, hinting at another hike. Plain meaning: money got more expensive, exposing weak finances. (Federal Reserve, September 16.)
- Retail sales rose 1.2% in August, versus 0.8% expected. Sales excluding autos rose 1.4%, versus 0.6% expected. Plain meaning: shoppers are still spending, good for revenue today, awkward for inflation tomorrow. (Nasdaq economic calendar, 8:30 a.m. ET.)
- Nebius Group (NBIS) traded at $229.35, up 9.54% before the opening bell. The AI-computing provider raised prices for access to high-end graphics chips. Plain meaning: pricing power is real money, unlike most AI press releases, which are PowerPoint wearing cologne. (Nasdaq, 8:47 a.m. ET; Investor's Business Daily.)
The Noise
- “One rate hike kills the rally” is lazy math. Futures rose because the uncertainty finally cleared. Plain meaning: the first reaction is not a law of nature.
- Every Nvidia (NVDA) valuation essay published before breakfast. Shares were $218.55, up 2.17% before the bell, but a clever ratio changes no cash flow. Plain meaning: a hot stock can attract hot takes without producing new information. (Nasdaq, 8:43 a.m. ET.)
- Tiny earnings beats from companies nobody can trade cleanly. Thin volume, meaning few shares trading, can create silly jumps. Plain meaning: a loud percentage move may still be financially irrelevant.
On the Clock
- 8:30 a.m. ET, retail sales: already out at 1.2%, stronger than forecast. Rising bond yields, the government's borrowing rates, would signal fear of more Fed tightening.
- 10:00 a.m. ET, business inventories and homebuilder confidence: economists expected inventories up 0.6% and the housing score at 34. More unsold goods or weaker builders would signal cooling demand. (Nasdaq calendar.)
- 10:30 a.m. ET, oil inventories: economists expected crude stockpiles to fall 1.6 million barrels. A bigger draw can lift oil prices, while a surprise build can hit producers again.
- Earnings: Innate Pharma (IPHA) reported before the bell. VinFast Auto (VFS) and Hub Group (HUBG) have no confirmed release time, while Upexi (UPXI) reports after the close. None can steer the whole market. (Nasdaq earnings calendar.)
- Fed speakers: none scheduled on the official calendar this morning. Yesterday's statement does the talking.
IPO Watch
- Haymaker Acquisition Corp. V (proposed HYACU), September 17, $10: a shell company raising $250 million to buy a business later. Watch the target, because this is a mystery box.
- Holtec Nuclear (proposed HNUC), expected September 18, $15 to $18: it builds nuclear equipment and handles spent fuel. Demand near the top of the range would show appetite for nuclear infrastructure.
- Orion180 Insurance Group (proposed OIG), expected September 18, $15 to $17: it sells homeowners insurance. Watch loss reserves, money saved for future claims, because cheap insurers can hide expensive storms.
- Electra Therapeutics (proposed ETRA), expected September 18, $14 to $16: it develops immune-disease drugs. Watch clinical results and cash burn, the speed it spends money, because biotech lives or dies there. (Nasdaq IPO calendar.)
Levels I Am Watching
- SPDR S&P 500 ETF Trust (SPY): $763.48 at 8:47 a.m. ET. Yesterday's $761.67 high is the first floor. Below it, $754.05 separates a rebound from a sugar rush. (Nasdaq real-time quote; Yahoo Finance daily range.)
- Invesco QQQ Trust (QQQ): $715.90 at 8:47 a.m. ET. $711.88 is yesterday's ceiling where sellers appeared, called resistance. Below it, $704.72 is the next test. (Nasdaq; Yahoo Finance.)
- Nebius Group (NBIS): $229.35 at 8:47 a.m. ET. $220.40 was yesterday's high and first floor. $209.37 would erase the price-hike celebration. (Nasdaq; Yahoo Finance.)
Term of the Day
Basis point: one hundredth of one percentage point. A 25-basis-point rate hike means rates rose 0.25 percentage point, the finance version of slicing an onion precisely instead of swinging a machete.
The Posture
Patient. Let the opening jump prove buyers can hold it, because chasing the first green candle after a Fed shock is how disciplined people pay impatient people's bar tabs.
Stay sharp. Stay honest. DBTech45.
