US Stock Market Summary for June 26, 2026

The US market closed a heavy week. The Nasdaq fell 0.24% to 25,297, marking a fifth straight losing session; the S&P 500 slipped 0.05% to 7,354; and the Dow lost 0.09% to 51,876. The index-level declines were modest, but underneath the surface it was a day of stark confrontation — a rout in chip and memory stocks running headlong into strength in healthcare and defensives. Even though about 66% of S&P 500 constituents closed higher, heavy-weighted chip mega-caps dragged the index down — a textbook divergent tape. On a weekly basis, the Nasdaq shed 4.6% and the S&P 500 roughly 2%, snapping a two-week winning streak, while the Fear & Greed Index slid to 25, settling into "extreme fear" territory. (Source)

Sector flows boiled down to risk-off rotation. Healthcare surged 3.03% to lead the tape, with real estate (+1.46%), consumer staples (+0.92%), consumer discretionary (+0.90%), and utilities (+0.76%) all climbing as defensive and rate-sensitive groups rallied in unison. Tech (-1.87%) and industrials (-1.59%), meanwhile, were weighed down by the chip selloff and weakness in Caterpillar ($CAT). In asset markets, the reopening of the Strait of Hormuz sent crude oil tumbling (crude oil ETF basis -3.50%), with supply normalization hopes prevailing even after news that Iran had attacked a cargo vessel. A flight to safety lifted gold (+1.13%), silver (+1.76%), and platinum (+1.93%), while mild bids for Treasuries pushed mid- to long-end prices higher.

The epicenter of the selloff was memory and chips. Western Digital ($WDC) plunged 13.17%, Seagate ($STX) fell 12.69%, and Sandisk ($SNDK) dropped 10.46% — all three memory names in double-digit decline territory. Micron ($MU) shed 7.47%, giving back a large chunk of its post-earnings surge from Wednesday, while Texas Instruments ($TXN), Analog Devices ($ADI), Qualcomm ($QCOM), Applied Materials ($AMAT), and Lam Research ($LRCX) all sold off as the chip complex declined broadly. A New York Times report that OpenAI may postpone its IPO further chilled AI- and chip-related sentiment, dragging down potential underwriters such as Morgan Stanley and Goldman Sachs. (Source)

On the other side, healthcare and select software names shone. Eli Lilly ($LLY) jumped 7.13%, and Moderna rallied nearly 15% after its mRNA flu vaccine received a unanimous 9-to-0 vote of confidence from a US Food and Drug Administration (FDA) advisory panel for adults aged 50–64 and 65 and older. AbbVie ($ABBV) and Johnson & Johnson ($JNJ) added roughly 4% apiece. Within big tech, performance diverged: software and services names such as Microsoft ($MSFT), Palantir ($PLTR), IBM ($IBM), and Netflix ($NFLX) rebounded around 5%, absorbing some of the capital rotating out of hardware.

> "This pullback in tech is a healthy correction. Many tech stocks had become excessively inflated, and this move should be viewed as a recalibration of expectations."

> — Rick Gardner, Chief Investment Officer at RGA Investments

> "The higher a stock's profile as a standout performer representing one sector's dynamism, the higher the market's expectations naturally climb. Realistically, those expectations are hard to meet, and disappointment ultimately shows up in the price action."

After five straight losing sessions, short-term indicators have tilted toward oversold, but with the chip uptrend broken and rotation into defensives unfolding simultaneously, the directional bias has yet to firm up on either side.
