Tech rebounds. Now comes triple witching.

Wall Street found its footing Thursday as oil and Treasury yields eased. Tech led the rebound. This morning, Nasdaq and S&P futures remain modestly higher while Dow futures have slipped just below flat. But Friday brings its own test: quarterly derivatives expiry, fresh factory data, and a rate hike from Japan.

Today: what powered the rally, two very different power-infrastructure trades, and why the latest economic numbers still leave the Fed with a difficult job.

Stocks rebounded a day after the Fed raised rates. Falling oil prices and Treasury yields gave buyers room to return, with technology leading the advance. Reports of Saudi crude moving through Oman helped ease supply concerns, although tensions in the region persisted.

Our read: cheaper energy could relieve pressure on company margins and household budgets. Lower bond yields also help the valuation math for growth stocks. Both supported Thursday's mood; neither guarantees a lasting recovery.

CASH: BULLISH CASE
Oil relief holds, borrowing costs stabilize, and earnings can do more of the work. A broader rally would make the rebound more convincing.

CHAOS: BEARISH CASE
Another supply shock could reverse the oil move. Inflation pressure would then return to the center of the rate debate.

The Nasdaq added nearly 440 points. Small caps joined in: the Russell 2000 rose 0.55% to 2,874.63.

For the week through Thursday, Massive ETF closes show SPY -0.22%, QQQ +0.29%, DIA -1.42%, and IWM -1.20%. These are ETF price changes since September 11, not index returns. Thursday's rebound left three of these four funds below last Friday's close.

Index figures: AP. Stock and ETF closing prices: Massive API.

Nine of the eleven sector ETFs finished higher, led by technology and consumer discretionary. Financials and communication services slipped.

These are September 17 close-to-close ETF price changes, calculated from Massive API daily closes for September 16 and 17 with split adjustment enabled. They exclude reinvested dividends and are not official sector-index returns.

GENERAC (GNRC): +18.34% to $207.23. The stock surged following its Amazon generator agreement. Initial deliveries are expected to total $2.4 billion in 2027–2028. The story now moves from winning business to fulfilling it.

FLUENCE (FLNC): -15.36% to $7.66. Its outlook cut landed hard. Fiscal 2026 revenue is now expected near $2.4 billion, with an adjusted EBITDA loss near $200 million, after U.S. production delays.

Our read: Strong demand for power infrastructure does not remove delivery risk. Orders, factory output and cash generation deserve separate scrutiny.

The latest timestamped quotes checked on Yahoo Finance show S&P 500 futures +0.11% at 7:34 AM ET, Nasdaq-100 futures +0.31% at 7:18 AM ET, and Dow futures -0.06% at 7:30 AM ET. These are delayed quotes with different timestamps, not a synchronized live snapshot.

Today is quarterly triple witching: stock options, index options and index futures expire. Position adjustments can lift trading volume and make intraday moves harder to interpret.

Our read: Expiry is a reason to watch the quality of a move, not a forecast that prices must rise or fall.

Labor: Initial jobless claims fell to 196,000 in the week ended September 12, down 10,000. That points to limited layoffs; it does not, by itself, establish strong hiring.

Factories: The Philadelphia Fed's September activity index eased to 37.8 from 47.4, remaining positive. Its prices-paid index climbed to 48.6 from 40.9. These are survey balances, not percentage growth rates.

Housing: August permits fell 2.7% to an annualized 1.394 million. Starts were estimated at an annualized 1.275 million; their reported 2.6% monthly decline was not statistically significant.

CASH: BULLISH CASE
Low layoffs and expanding factory activity give the economy a cushion while borrowing costs stay elevated.

CHAOS: BEARISH CASE
Rising factory price pressure complicates the inflation fight, while weaker permits point to caution in future building activity.

The Bank of Japan raised its policy rate from 1.00% to 1.25% on Friday, the highest level in 31 years. The vote was 7–2.

The yen weakened after the decision. The expected hike did not deliver an unambiguously hawkish surprise, and the two dissents drew attention.

Why it matters: Higher Japanese rates raise the cost of funding positions with borrowed yen. Watch the currency and bond-market reaction for signs of adjustment; the rate decision alone does not establish that a broad unwind is underway.

TCOM: Macquarie upgraded Trip.com from Neutral to Outperform, with a $53.20 price target.

FLNC: Baird cut Fluence from Neutral to Underperform with a $3 target. Goldman Sachs cut it from Buy to Neutral with a $9 target. Same company, very different valuations.

PANW: Bernstein downgraded Palo Alto Networks from Outperform to Market Perform, with a $351 target.

9:15 AM: August industrial production and capacity utilization. Watch whether national factory output supports the regional survey picture.

9:30 AM: Fed Vice Chair for Supervision Michelle Bowman speaks in London. The listed topic is stress testing.

Through the session: Quarterly derivatives expiry. Settlement times vary by contract; activity may be heavier around settlement and the close.

Thursday gave bulls a better screen. Today, watch whether oil relief holds, buying reaches beyond tech, and the rally survives a busy expiry session. The first bounce is encouraging. Follow-through will tell us more.
