Cheaper Crude Fuels a 2.69% Nasdaq 100 Jump

Global equities opened the week higher on Monday, with the Nasdaq 100 proxy QQQ up 2.69% at $740.88 as of 18:44 GMT, as falling oil prices and optimism over this week's Washington-Beijing talks lifted technology shares.

Technology shares did the heavy lifting on Monday as global equities opened the week with a broad advance, helped along by a further slide in oil prices and investor hopes for this week's talks between Washington and Beijing.

The Invesco QQQ Trust (NASDAQ: QQQ), which tracks the Nasdaq 100, was changing hands at $740.88 as of 18:44 GMT, up 2.69% from Friday's close of $721.45 and sitting within a whisker of its intraday high of $740.89. The SPDR S&P 500 ETF Trust (NYSEARCA: SPY) was at $774.03, a gain of 1.62% against a previous close of $761.69. The SPDR Dow Jones Industrial Average ETF Trust (NYSEARCA: DIA) lagged at $520.09, up 0.82%.

That spread — tech up more than three times as much as the Dow — is the story in a single line. This was not an even-handed risk-on session. It was a growth-stock session, and the ranking of the three benchmarks tells you where the money went.

How falling oil turns into a bid for growth stocks

The link between a softer crude price and a firmer Nasdaq is not direct, but it is reliable. Energy is an input cost across the economy and a large component of headline inflation. When oil falls, near-term inflation expectations tend to ease with it, and bond yields typically follow. Lower yields matter disproportionately for technology companies because so much of their valuation rests on profits expected years out. Discount those distant cash flows at a lower rate and the present value rises.

The mirror image is also at work in the index spread. The Dow carries more weight in energy, industrials and other economically sensitive businesses whose revenue benefits from higher commodity prices. Cheaper crude trims that revenue while it flatters the long-duration growth complex. A day when the Nasdaq 100 gains 2.69% and the Dow manages 0.82% is close to a textbook illustration of that split.

Consumers sit on the other side of the same trade. Falling crude eventually reaches the pump, and fuel is one of the few prices households check weekly. Any relief there frees up discretionary spending, which is one reason equity investors treat a crude slide as a net positive even when it dents the energy sector's own earnings.

What the Washington-Beijing talks put on the table

The second leg of Monday's advance was diplomatic rather than economic. Optimism around this week's discussions between US and Chinese officials gave buyers a reason to add exposure ahead of the headlines rather than wait them out — a notable shift in posture after a stretch in which caution was the default.

Technology is the sector with the most riding on the outcome. Semiconductor supply chains, export controls and tariff schedules all run through the US-China relationship, and hardware and chip names are the ones whose cost bases and addressable markets move most on any change. A market that buys tech ahead of a bilateral meeting is a market pricing a constructive result, which also means it has left itself exposed if the meeting disappoints.

As WSJ Markets reported, the rally was accompanied by lower government bond yields, consistent with the oil-to-rates transmission that underpinned the move in growth shares.

The tape's internals: a rally that closed on its highs

The intraday ranges are worth reading carefully. QQQ traded between $727.31 and $740.89, and its last print of $740.88 was effectively at the top of that band. SPY ranged from $766.03 to $774.07 and printed $774.03 — again, at the upper edge. DIA moved between $516.76 and $520.13 and sat at $520.09.

All three benchmarks holding near the top of their daily ranges suggests buyers were not fading strength as the session wore on. That pattern typically reflects real demand rather than a gap higher that slowly leaks away, though a single session establishes a mood and not a trend.

Worth noting too: QQQ's low of $727.31 was still above Friday's close of $721.45, meaning the fund never traded in the red during the period covered by the data. The same holds for SPY, whose low of $766.03 topped its $761.69 prior close, and for DIA, which bottomed at $516.76 against a $515.88 close. Sellers, on this evidence, barely showed up.

Where the risk sits from here

Two of Monday's drivers can reverse quickly. Oil has proved capable of sharp moves in both directions, and a rebound in crude would unwind the yield relief that supported the highest-multiple names first. The bilateral talks are a binary event in the short run: an outcome that falls short of what the market has now begun to price would hit the same technology shares that led the advance.

The practical checklist for the days ahead is short. Watch whether crude extends its decline or stabilises. Watch the direction of government bond yields, which are the mechanism converting the oil move into equity valuations. Watch whether the Dow starts to close the gap on the Nasdaq, which would signal the rally broadening beyond growth. And watch the language coming out of the talks themselves, because the positioning going in now assumes cooperation.

For long-term holders, none of this changes much: a one-day 2.69% move in a broad index fund is noise against a multi-year horizon. For anyone trading around the event, the asymmetry has shifted. The market has already banked a good chunk of the good news.

Frequently asked questions

How much did the main US benchmarks gain on Monday?

As of 18:44 GMT on Monday 21 September 2026, the Nasdaq 100 tracker QQQ was up 2.69% at $740.88, the S&P 500 tracker SPY up 1.62% at $774.03, and the Dow tracker DIA up 0.82% at $520.09. The technology-heavy benchmark led by a wide margin over the industrial-leaning Dow.

Why do falling oil prices help technology stocks?

Cheaper crude eases headline inflation, which tends to pull government bond yields lower. Technology valuations depend heavily on profits expected years into the future, and those distant cash flows are worth more when discounted at a lower rate. Lower energy costs also leave consumers with more discretionary spending power.

Why did the Dow lag the Nasdaq so badly?

The Dow carries greater weight in energy, industrials and other commodity-sensitive businesses whose revenue benefits when oil is expensive. A crude decline trims their earnings outlook while simultaneously boosting long-duration growth stocks. The 0.82% Dow gain against a 2.69% Nasdaq 100 move reflects that sector split rather than a broad risk-off tone.

What are the US-China talks and why do they matter for markets?

Officials from Washington and Beijing are meeting this week. Investors bid up equities in advance on optimism about the outcome. Technology has the most at stake because semiconductor supply chains, export controls and tariff arrangements run directly through the bilateral relationship, affecting both costs and addressable markets for chip and hardware companies.

Did stocks trade negative at any point during the session?

Based on the intraday data, no. QQQ's session low of $727.31 was above Friday's close of $721.45, SPY's low of $766.03 topped its $761.69 close, and DIA's $516.76 low exceeded its $515.88 close. All three finished the reported period near the top of their daily ranges.

What should investors watch next?

Three things: whether crude continues falling or rebounds, since that reverses the yield relief supporting growth shares; the direction of government bond yields, which transmit the oil move into equity valuations; and the actual outcome of the Washington-Beijing talks, given the market has already priced in a constructive result.
