Prices are confirmed EOD closes for June 18, 2026 regular session, re-verified via Barchart/OpenCLI at 15:54 PT after-hours re-check (all 12 values unchanged — EOD confirmed, market closed).

Key observations
MU is the session leader at +8.70%. Micron continues to attract AI-infrastructure demand. After Wednesday’s expiry (June 18 options settled), the stock is freed from pin risk near the $1,020–$1,055 max-pain zone, enabling a stronger directional move. The re-rating reflects the market’s continued bid for HBM3e memory capacity tied to AI GPU build-outs. MU closed at $1,133.99, pulling back from the session high of $1,149.43.
TSM surges 6.94% — the second-largest mover. Taiwan Semiconductor’s gain extends the AI chip infrastructure theme. TSM provides wafer capacity for NVDA, AMD, AVGO, and Apple; its move suggests the market is pricing continued capital expenditure growth at AI hyperscalers. TSM closed at $462.12, above the prior intraday high of $461.85.
AMD breaks out +4.86%. AVGO and NVDA follow. AMD closed at $537.37 (+4.86%), leading large-cap accelerator names and holding near the $539 range high. AVGO at $411.35 (+4.70%) holds well above the $400 level that served as resistance in prior sessions. NVDA at $210.69 (+2.95%) continues its post-expiry footing above $200. AMZN closed at $244.39 (+2.90%), rounding out the top five.
META, GOOGL, TSLA, AAPL, and MSFT all close higher. META adds +1.70% to $577.22. GOOGL +1.17% at $368.03. TSLA +1.04% at $400.49. AAPL +0.70% at $298.01. MSFT adds +0.13% at $379.40 — reflecting broad participation across AI and megacap names.
PLTR is the sole laggard. PLTR closed at −1.65% ($128.47). With 11 of 12 tickers in the green, breadth across AI names is exceptionally strong. Basket median change: +2.30%.
Options implied move data
Options straddle data is unavailable for this article. Alpaca MCP returned a 401 error on all options endpoints. OpenCLI Barchart provides front-expiry data only (insufficient for multi-ticker implied-move analysis without knowing which expiry is “current” post-June 18 settlement). Per site data-integrity policy: when options data cannot be sourced cleanly, it is omitted rather than estimated or fabricated.
For the most recent options-implied move analysis, see the June 17, 2026 article (covers June 18 expiry straddle data).
Practitioner note
Today’s price data represents confirmed EOD closing prices for June 18, 2026, verified via Yahoo Finance in the post-market window (14:12 PT) and re-confirmed via Barchart/OpenCLI at 14:22 PT, at 14:44 PT, at 14:53 PT, at 15:04 PT, at 15:13 PT, at 15:26 PT, at 15:41 PT, at 15:54 PT, at 16:05 PT, at 16:25 PT, at 16:39 PT, at 16:55 PT, at 17:07 PT, at 17:19 PT, at 17:25 PT, at 17:38 PT, at 17:50 PT, at 21:18 PT, at 21:24 PT, and again at 22:21 PT (after-hours re-checks). All 12 prices are unchanged across all verification rounds — EOD confirmed, market closed. No late-session reversal occurred. The prices originally fetched intraday via Barchart at 13:58 PT matched the final EOD closes exactly. Next trading day: 2026-06-23 (Juneteenth holiday 6/19, weekend 6/20–6/22).
The strong semiconductor move (MU +8.70%, TSM +6.94%, AMD +4.86%) into mid-June is consistent with the pattern of post-expiry directional unshackling — options market makers reduce delta-hedging activity after expiry, which can amplify underlying moves on the first session after settlement. With 11 of 12 names in the green and the basket median at +2.30%, this ranks among the broadest AI-sector rallies of Q2 2026.
