Daily Market Brief — 2026-07-21

A pre-open look at US markets: what moved Monday, what futures are signalling, and which sectors are leading.

Market backdrop

US equities closed mixed on Monday, 20 July. The S&P 500 slipped −0.19% to 7,443.28, the Nasdaq Composite was almost unchanged at −0.05% (25,508.07), and the Dow Jones Industrial Average took the day's damage, falling 307.16 points, or −0.59%, to 51,839.26. Crude advanced on renewed military exchanges between the US and Iran, reviving inflation and rate concerns and weighing on the more cyclically tilted Dow while an attempted semiconductor recovery kept the Nasdaq flat.

Tuesday's pre-open tape is firmer and led by technology. Dow futures are up +0.3%, S&P 500 futures +0.5%, and Nasdaq-100 futures +1.3% — a second consecutive session of strength in chip names. The VIX sits at 17.74, down 4.88%, easing from last week's expansion but still above the 15–16 band that prevailed through the middle of the month.

Two other threads are live in the tape: a heavy week of corporate earnings now beginning, and fresh US tariffs on Canada.

Sector rotation

Monday inverted the pattern that dominated early July. For most of the month the Dow outperformed while the Nasdaq lagged; on Monday the reverse occurred, and Tuesday's futures widen that gap further.

The proximate cause is a semiconductor comeback that is now two sessions old — though the recovery is more visible in individual names than in the index. The main semiconductor sector fund traded near $521.81 against a $530.50 prior close, and the semiconductor complex remains roughly −17% over the past month even as it retains a gain of about +89% year to date. The Technology Select Sector SPDR is up roughly 33% year to date. Energy retains a bid on the Middle East headlines.

The fairer characterisation of Monday: not a broad move into technology, but company-specific re-ratings inside a handful of artificial-intelligence infrastructure names on a day the broad index fell.

Rates, the dollar & regime

The 10-year US Treasury yield climbed to roughly 4.57–4.60% on Monday, recovering the prior week's decline as higher crude revived inflation and rate-hike concerns. Longer-dated government bonds therefore weakened alongside a soft equity tape — the flight-to-quality behaviour observed on 16 July has not repeated in either of the two sessions since, leaving it an isolated episode rather than an established pattern.

Volatility is easing from last week's spike without returning to the complacency of mid-July. No reliable fresh reading was available for gold or the US dollar index at the time of writing, and neither is estimated here.

Taken together: a risk-on pre-open with an inflation overhang, in which oil remains the clearest channel from geopolitics into longer-duration equities.
