Day Trader Pulse: Chips Rallied, BFLY Soared 56%, ACN Crashed, and Markets Are Closed

Intel led a 5.4% semi index surge on Apple deal reports, Butterfly Network exploded on Midjourney's medical AI play, and Accenture lost 18% on weak guidance, all ahead of a Juneteenth pause.

U.S. markets are closed Friday, June 19 for Juneteenth. But Thursday's session left day traders with plenty to digest over the long weekend — a semiconductor-led rally, a 56% momentum explosion in Butterfly Network, and an 18% collapse in Accenture that rippled across the IT services sector.

The Semi Blowout

The Philadelphia Semiconductor Index (SOX) surged 5.4% on Thursday. Intel (INTC) jumped 10.6% after reports of a landmark deal with Apple to design and manufacture chips domestically, validating Intel's 18A-P process technology. The move was a shot of adrenaline for the entire sector.

The rally spread fast: SanDisk (SNDK) gained 11.5%, Corning (GLW) 11.1%, Super Micro Computer (SMCI) 10.4%, KLA Corp (KLAC) 8.7%, and Micron (MU) 8.7%. Wolfspeed (WOLF) rallied roughly 18% on heavy volume — momentum-driven, with no analyst upgrades behind it. Short-covering and AI silicon-carbide demand narrative appear to be the fuel.

For momentum traders, the open on Monday (June 22) is the real test: does the rally hold, or is this a holiday-shortened flash in the pan?

BFLY: The AI-Med Momentum Trade

Butterfly Network (BFLY) closed at $8.90, up 55.9% on nearly 10x normal volume. The catalyst: Midjourney — best known for its AI image generator — launched Midjourney Medical and unveiled a full-body ultrasonic CT scanner using roughly 40 of Butterfly's Ultrasound-on-Chip modules.

Butterfly confirmed the November 2025 co-development and licensing agreement includes upfront fees, annual payments, milestones, and revenue sharing worth up to $74 million over five years. For day traders, BFLY is the classic AI-hype momentum setup: oversized volume, a headline-rich catalyst, and extreme downside risk if the enthusiasm fades.

Accenture's 18% Rout

On the bearish side, Accenture (ACN) plunged 18% to roughly $128 — its lowest in nearly nine years. The Q3 results beat on EPS ($3.80 adjusted vs. $3.70 consensus), but the forward guidance was a shock: full-year revenue growth was cut to 3%-4% in local currency.

CEO Julie Sweet cited a roughly $400 million hit from Middle East conflict disruption, plus clients pausing traditional consulting spend as they navigate the AI transition. Cognizant (CTSH) fell 10.5% in sympathy. Traders are now watching if more IT services names could face similar headwinds in coming weeks.

The Macro Overhang: October Rate Hike

Wednesday's FOMC decision — the first under Chair Kevin Warsh — held rates at 3.50%-3.75% but delivered a meaningfully hawkish dot plot. The median end-2026 rate projection jumped to 3.80%, implying at least one 25 bp hike by year-end.

Nine of 18 officials see at least one hike; six see more than one. Markets are now pricing October as the live meeting. For day traders, this means volatility plays will stay on the menu through the summer and into fall.

What to Watch Next Week

Markets reopen Monday, June 22. Key questions on the table:

Semiconductor momentum — can INTC hold the Apple-deal gains?
Accenture hangover — does the 18% gap attract dip buyers, or is this the start of a sector repricing?
BFLY follow-through — does the AI-medical narrative sustain, or was Thursday the peak?
PCE data — later this month, the Fed's preferred inflation gauge will test the hawkish narrative.

The Bottom Line

Juneteenth gives traders a day to reset and reposition. The dominant signal from Thursday is clear: semis and AI are still the alpha plays, while legacy IT services face a structural reckoning. Monday's open will tell us whether this week's extremes were the start of a trend — or just a very volatile pause.
