Wednesday’s session is a study in asymmetry. While Wendy’s surged 24% and Sunrun rocketed 22% on the Iran peace dividend, some of the most dramatic collapses of the week are also happening today. Hertz crashed 27.3% — one of the worst single-day losses in the auto rental industry in years. Cerebras reversed its recent gain with a 16% drop. SpaceX continues its relentless post-IPO correction toward $153. And gas station chains are paying the price for a world where WTI just hit $70/barrel. Here is the complete breakdown of Top Stock Losers Today — and why each story matters heading into Micron’s earnings tonight.

Wednesday June 24 — Session Losers Context

🔴 Top Stock Losers Today — Wednesday, June 24, 2026

1. HTZ — Hertz Global Holdings | -27.3%

Hertz’s 27.3% single-session collapse is the sharpest individual equity drop of Wednesday’s session — and a direct product of the Iran peace dividend that is simultaneously lifting airlines and crushing every company that profits from the automotive status quo.

Why Hertz gets hit when oil falls sharply:

• Hertz has been aggressively building an EV fleet as a strategic differentiator. Lower gas prices reduce the economic incentive for renters to choose EVs over gas-powered alternatives — damaging the premium Hertz was charging on its Polestar and Tesla fleet categories
• When oil is at $70, a renter at an airport can fill a gas-powered vehicle cheaply — the EV value proposition (lower fuel costs per mile) narrows dramatically
• Airlines were Hertz’s natural “feeder” at airports. As airlines add capacity and fares come down with oil prices, more travelers fly — but travelers now book Uber and Lyft at airports at far higher rates than traditional car rental desks
• Hertz has been in bankruptcy-adjacent discussions twice in recent years; any demand pressure at current valuation levels triggers outsized selling

2. CBRS — Cerebras Systems | -16.1%

The irony of Cerebras falling 16.1% on Wednesday is stinging. Just Tuesday, Cerebras was the only AI chip name that gained (+1.02%) on the day the entire semiconductor sector lost 7.9%. On Wednesday, the stock reversed sharply.

• The direct catalyst: OpenAI and Broadcom announced a joint custom AI chip Wednesday morning. Cerebras had been gaining in part on the narrative that hyperscalers would seek GPU alternatives — but now OpenAI has chosen Broadcom, not Cerebras, as its custom silicon partner
• This is a significant competitive blow to the “Cerebras as the anti-Nvidia” narrative; if OpenAI — the world’s most valuable AI research lab — builds custom silicon with Broadcom rather than adopting Cerebras’s wafer-scale architecture, it narrows Cerebras’s addressable hyperscaler market
• Cerebras is still a compelling differentiated architecture story for certain workloads (inference at low batch size, edge AI), but losing the OpenAI narrative is a near-term headwind

3. CASY — Casey’s General Stores | -6.8%

Casey’s General Stores — the Midwest’s largest gas station and convenience store chain — is paying the exact price you’d expect when oil falls nearly 4% and WTI hits $70/barrel.

The gas station economics of a rapid crude crash:

• When oil falls sharply, wholesale fuel costs drop faster than retail pump prices — creating an initial windfall (high retail price vs. cheap wholesale). But this effect reverses within 2–3 weeks as competition forces pump prices down
• On the way down, gas stations lose throughput revenue: consumers drive more miles at lower prices, but the margin per gallon compresses significantly
• Trump’s DOJ investigation into oil company “gouging” (announced Wednesday) adds regulatory pressure to pass lower costs through to consumers faster — directly compressing Casey’s pump margins on a shorter timeline
• Casey’s food and convenience segment remains strong, but fuel represents ~75% of revenue and ~40% of gross profit for the company

4. SPCX — SpaceX | -1.61% to $153.60 | Correction From $225.64 ATH

SpaceX extends one of the most rapid post-IPO corrections in recent large-cap history. From an intraday all-time high of $225.64 on June 16 to $153.60 on Wednesday — a 32% correction in just 8 trading sessions.

Why SPCX is falling continuously:

• From $225 to $153 is not a technical pullback — it is an aggressive reassessment of whether an AI-facing, debt-funding company with -45% net margin deserves the world’s 2nd-highest valuation
• The “AI is overhyped” narrative (which sent semiconductors -7.9% Tuesday and Nasdaq -2.21%) applies directly to SpaceX’s $60B Cursor acquisition — the market is asking the same ROI question it’s asking Nvidia, Intel, and Microsoft
• Crucially: SpaceX has no earnings call until September 2. Every day between now and then is pure narrative and float dynamics — no quarterly checkpoint to provide fundamental clarity
• At $153.60, SPCX is only $18.60 above its IPO price — meaning the post-IPO momentum buyers who chased the stock to $225 are sitting on losses of up to 32%

Key level to watch: $135.00 (IPO price). This is the absolute floor for primary IPO allocation holders. If SPCX breaks below $135, the signal to the market is that even IPO buyers have lost confidence. At $153.60, there is still a $18.60 buffer.

5. Oil Sector — Day 8 of Decline | XLE, XOM, CVX Under Pressure

WTI crude at $70/barrel is the lowest level since the Iran war began — and oil-producing stocks have now experienced eight consecutive sessions of selling pressure:

Energy stocks have now given back virtually all their Iran-war premium. With WTI at $70 — barely $2 above the pre-war $68 level — the oil war trade is functionally over. The remaining question is whether Iranian supply normalization creates structural oversupply that drives crude below $68 by Q3. If yes, oil stocks face another leg lower; if crude stabilizes here, the sector bottoms.

6. SPCX, Bitcoin, Nasdaq — The AI Skepticism Continuation

The broader AI-skepticism narrative from Tuesday’s -7.9% semiconductor selloff did not fully resolve Wednesday:

• Nasdaq: -0.41% (continued tech underperformance vs. Dow)
• Bitcoin: -2.22% to $61,066 (risk-off/dollar at 1-year high)
• Dollar Index (DXY): 1-year high — strong dollar compresses multinational tech earnings
• AI spending debate: Capital Economics’ James Reilly: markets still digesting “frothy earnings expectations and/or valuations” with no major catalyst to reset

The Session Hinge: Micron After the Bell

Every loser listed above has a potential Wednesday night reprieve — or compounding reversal — depending on Micron’s Q3 FY2026 print after 4:00 p.m. ET.

Hertz and Casey’s are immune to Micron — their stories are oil-macro, not AI-chip dependent. But CBRS, SPCX, and the broader AI-complex have a binary event at 4:00 p.m. today that will either staunch the bleeding or accelerate it.

The two most important numbers from tonight’s Micron call:

1. HBM revenue (must show acceleration above $1B quarterly)
2. Q4 FY2027 guidance (must show the supercycle extends)
