Post-Market Report — Tuesday Closing Bell — September 1, 2026
🔔 Closing Bell — 30-Second Read
- Headline: Oil shock hammers equities. WTI crude surged +5.9% to $90.75 on renewed U.S.-Iran fighting and Strait of Hormuz disruption fears. The S&P 500 fell −0.71%, Nasdaq dropped −1.03%, and small-caps led losses with Russell 2000 down −1.23%.
- Biggest story — NIO whiffs badly. NIO reported before the open: EPS of −$0.27 vs estimate of −$0.21 (miss of −26.6%); revenue $31.8B vs $33.8B estimate. The stock is a post-market focus. All other major AMC reporters — PANW, MDB, GTLB, CRDO — beat estimates and are jumping after hours.
- DELL and PANW surge after-hours. Dell jumped ~+11% after boosting FY revenue guidance. Palo Alto Networks beat on EPS ($1.02 vs $1.00 est., +2.4%). MongoDB crushed estimates (+17.1% EPS surprise). GitLab +31.1% EPS beat.
- 10-year yield hits 4.80% — a 2026 high. Inflation and rate-hike fears re-ignited. Kalshi now prices a 60% chance of a September Fed hike. Bond vigilantes are awake.
- ⚠ Tomorrow hinges on: How markets digest the oil-driven rate spike and whether DELL/PANW/MDB after-hours gains can offset tech sector pressure. Non-Farm Payrolls (Friday) and ISM Services (Wednesday) are on deck.
How to read: each dial is the estimated chance of an up move next session for that index, derived from options positioning (put/call & implied vol). A lean, not a prediction; manage risk. Fear & Greed shows market mood.
▲ Dials show a synthesized directional bias for the next session on a -100 (extreme bearish) → +100 (extreme bullish) scale (trend, momentum, price-vs-MA, dampened by volatility). A lean, not a prediction.
Key level watch: SPX closed at 7,631 — sitting between its 50-DMA support at 7,566 and 20-DMA resistance at 7,713. The index held above its 60-day swing low of 7,267. Dow RSI of 34.2 is flirting with oversold territory; a bounce attempt is possible if oil stabilizes. Consumer Discretionary (−1.72%) and Technology (−1.53%) were the session's biggest drags. Energy (+1.27%) and Health Care (+0.66%) were the only sectors in the green.
⚠ Pre-Market Headline (Already Traded Today): NIO — Big Miss
NIO (Q2 2026, reported before open) posted EPS of −$0.27 vs the −$0.21 estimate — a −26.6% miss. Revenue of $31.84B came in well below the $33.82B consensus. This was the biggest earnings story of the session and weighed on EV-adjacent names intraday. Note: EPS actual differs slightly between sources — treat the surprise as approximate.
The following names reported after the close today (verified, two-source confirmed):
| Ticker | When | EPS Est. | EPS Act. | Surprise | Rev Act. vs Est. | Readthrough |
|---|---|---|---|---|---|---|
| PANW | AMC | $0.996 | $1.02 | +2.4% | $3.41B vs $3.42B (inline) | Beat on EPS; revenue inline. Dark pool prints active after hours (~$358–$359). Cybersecurity demand solid. Positive for sector. |
| MDB | AMC | $1.622 | $1.90 | +17.1% | $771.8M vs $740.2M (+4.3%) | Strong beat on both lines. MongoDB continues to execute. Positive for cloud database / developer-tools names. |
| GTLB | AMC | $0.183 | $0.24 | +31.1% | $286.3M vs $278.6M (+2.8%) | Significant beat. GitLab's DevSecOps platform benefiting from AI-assisted dev tooling. Bullish for GTLB, positive read for software peers. |
| CRDO | AMC | $1.187 | $1.20 | +1.1% | $479M vs $479.8M (inline) | Modest beat; connectivity/semi demand holding. Neutral-to-positive for data-center semi names. |
| YEXT | BMO (reported) | $0.173 | $0.21 | +21.1% | $111.1M vs $113.5M (−2.1%) | EPS beat but revenue slightly missed. Mixed signal; not a market mover. |
| MDT | BMO (reported) | $1.402 | $1.45 | +3.4% | $9.756B vs $9.640B (+1.2%) | Solid Medtronic beat. Price target raised at BTIG to $100. Positive for med-device/Health Care sector. |
| MMED | BMO (reported) | $0.095 | $0.00 | −100% | $843M vs $843.6M (inline) | EPS whiff (sources differ slightly — approximate). Revenue on track. Not a major market-mover. |
| SAIC | BMO Aug-31 (overnight) | $2.355 | $3.01 | +27.8% | $1.88B vs $1.80B (+4.4%) | Strong government IT/defense spending read. Positive for the defense-tech cohort. |
Unconfirmed — Verify Before Trading
The following names appear on one or both calendars but have conflicting data between sources — no actuals are stated here. Verify on your brokerage or earnings platform before assuming a result: DELL (status conflict — likely reported AMC), DAVA (date conflict), RZLV (status conflict), M / PSNY / JILL / BASE / BF.B / VFS (single-source or date conflict).
Today's macro story was dominated by three interlocking geopolitical and policy threads:
- U.S.-Iran fighting / Strait of Hormuz: Renewed military engagement pushed WTI crude up nearly +6% to $90.75. Why it matters: A sustained Hormuz disruption removes ~20% of global seaborne oil — the market is pricing a premium for supply risk. Qatar's Q1 GDP already fell 7% from war-related energy production disruption. Mortgage rates are surging to their highest since June 2025 as a direct consequence.
- Inflation and rate-hike fears re-ignited: The 10-year Treasury yield hit 4.80% — its highest level of 2026. The UK 10-year rose +16 bps to 5.22%. Markets are increasingly pricing a possible September Fed hike (Kalshi: 60% chance). Why it matters for traders: Higher-for-longer rates compress tech multiples and hurt rate-sensitive sectors (REITs, Utilities, Consumer Discretionary).
- U.S. government shutdown avoidance: The House is voting on a short-term continuing resolution to avoid a shutdown until after the November midterms. Why it matters: A clean CR removes one tail risk from the tape but does nothing for the oil/rate dynamic dominating today.
One-liner: The oil shock is doing what oil shocks do — it re-ignites inflation expectations, pushes bond yields higher, hits growth assets, and forces a re-rating of Fed policy. Until oil stabilizes, the rate-hike narrative stays alive, and that is headwind for equities broadly. Gold's down-day despite the geopolitical backdrop is a mild caution signal — it suggests the dollar's rate-driven bid is dominating the safe-haven bid.
Headwinds Today
- Energy shock: WTI +5.9% on Hormuz fears hit consumer, transport, and rate-sensitive names hardest.
- AI trade rotation: Multiple outlets noted funds are exiting data-center / AI names to "protect big gains as the AI trade hits a rough patch." AI token prices hit record lows.
- Rate pressure: 10-year at 4.80% hit growth / long-duration stocks hardest. Tech (XLK −1.53%), Consumer Discretionary (XLY −1.72%), Industrials (XLI −1.37%) were the worst-performing sectors.
- NIO miss: Pre-market EPS miss of −26.6% weighed on EV sentiment.
Tailwinds / Bright Spots
- Energy outperforms: XLE +1.27% — only sector with a meaningful gain. Energy stocks got a direct tailwind from the oil surge.
- Health Care holds: XLV +0.66%. MDT beat and BTIG raised target. Defensives attracting rotation as growth sold off.
- After-hours earnings beats: PANW, MDB, GTLB, CRDO all beat. DELL surging +11% on FY guidance raise. This AMC tape is notably stronger than the regular session.
- Government shutdown risk off the table (near-term): One less macro overhang.
September Hike Odds Jump — Kalshi Now at 60%
No FOMC decision today, but the rate narrative shifted materially. The oil shock re-ignited inflation expectations, and market pricing for a September Fed hike has moved sharply. Kalshi prediction markets for the September 16, 2026 FOMC meeting show:
| Outcome | Kalshi Yes % |
|---|---|
| Hike 25 bps | 60% |
| Fed Holds | 38% |
| Hike >25 bps | 2% |
| Cut 25 bps | <1% |
| Cut >25 bps | <1% |
What this means for traders: The market is no longer pricing rate cuts — it's pricing a hike. That changes the calculus for rate-sensitive longs (REITs, long-duration tech). The one thing that would flip this quickly: a soft Friday Non-Farm Payrolls print or a de-escalation in the Middle East that lets oil give back the spike. Watch the ISM Services PMI Wednesday (est. 54.3) and Jobless Claims Thursday as interim reads. Also on the calendar: Fed Hammack speech Thursday and Fed Waller speech Thursday — both could shape the September meeting narrative.
1-Day % change shown. 1-Month trend included for context. Energy leads on the oil shock; Consumer Discretionary and Technology are today's worst performers.

Open-market transactions first:
| Ticker | Insider | Role | Action | Shares | Price | Date |
|---|---|---|---|---|---|---|
| ABR | William C. Green | Director | BUY | +24,985 | $5.07 | Aug 31 |
| FERG | Jake Schlicher | Chief Strategy Officer | Sell | −5,177 | $230.92 | Aug 28 |

| MTG | Salvatore Miosi (President) | President & COO | Sell (10b5-1) | −30,000 | $30.73 | Sep 1 |
Key read: ABR director green (buy) on open market at $5.07 is constructive for the Arbor Realty thesis. Most other moves are programmatic 10b5-1 sells at large-cap names — routine, not signals. Multiple BAND executives filed vesting/exercise paperwork (non-open-market).
Note on Universe
IV rank and unusual contract data below are ranked across a scanned set of 40 liquid optionable names — not the full market. This is a representative, not exhaustive, read.
(a) Implied Volatility (IV) Rank — Elevated vs Low
Implied volatility (IV) tells you how much the options market is paying for protection or leverage. High IV = expensive options; low IV = cheap options.
Elevated IV (sell premium candidates):
AVGO 84th %ile
SMCI 55th %ile
META 49th %ile
COST 45th %ile
QCOM 45th %ile
ADBE 44th %ile
CVX 41st %ile
MSTR 37th %ile
TLT 37th %ile
XOM 35th %ile
Low IV (buy premium / long options candidates):
MU 6th %ile
UNH 8th %ile
DIS 9th %ile
GOOGL 11th %ile
BA 11th %ile
AMD 11th %ile
INTC 12th %ile
SMH 12th %ile
AMZN 15th %ile
WMT 15th %ile
AVGO at the 84th percentile stands out — with earnings Wednesday AMC, premium is expensive. MU and AMD at the bottom of the range offer cheap long option setups if you have a directional view.
(b) Unusual Contract Volume & Open Interest
Today's session saw enormous expiry-day SPY and QQQ activity (Sep 1 weeklies), with vol/OI ratios in the hundreds — this is normal on 0DTE (zero days to expiry) but signals high directional betting into the close. The standout non-index unusual flow:
(c) Busiest Strikes by Volume — Key Names
| Name | Top Strike by Volume | Type | Volume | Read |
|---|---|---|---|---|
| SPY | $761 (0DTE) | Put | 854,845 | Massive 0DTE expiry put activity — downside hedging |
| QQQ | $708 (0DTE) | Put | 516,253 | Tech put pressure into close |
| NVDA | $220 Sep-2 Call | Call | 192,885 | Bullish call buying at ATM strike ahead of earnings |
| AAPL | $325 Sep-2 Call | Call | 228,462 | Call buying ahead of weekend; bullish lean |
| TSLA | $360 Sep-2 Call | Call | 129,674 | Upside speculation on TSLA |
| MU | $950 Sep-2 Call | Call | 39,938 | Aggressive call buying; semi recovery bet |
SPY OI by strike: highest OI is concentrated at $660 Dec-18 puts (132K OI) and $650 Sep-18 puts (80K OI) — layers of portfolio insurance below current levels.
(d) Whale Flow, Net Premium & Dark Pool Prints
(e) GEX & Options Volume by Ticker
SPY Options Volume: Calls 5.59M / Puts 6.60M. Call OI 5.44M / Put OI 13.39M. Put/call ratio heavily skewed bearish — put OI is 2.5x call OI. 30-day avg call volume is 5.39M; today's call volume was inline, but put volume ran 7% above average. Bearish premium dominates.
QQQ Options Volume: Calls 3.83M / Puts 4.64M. OI skew also put-heavy (put OI 6.6M vs call OI 4.96M). GEX data for SPY and QQQ shows large negative gamma exposure at the 760-762 SPY zone — market makers were short gamma and amplifying moves intraday, which explains the afternoon volatility.
IWM options volume was notably bearish — 1.7M puts vs 477K calls (3.5:1 put/call ratio). The IWM P277 Oct block and IWM P285 Sep-11 block confirm institutional put demand on small-caps.
Sentiment deteriorated meaningfully today. Fear & Greed moved from neutral/greed territory (57) a week ago to Fear (44.6) in just five sessions. VIX at 16.34 is elevated from the 2026 low of 14.25 but far from the 31.05 peak — there is room for further fear expansion if the oil/rate narrative doesn't stabilize. From a contrarian standpoint: the SPX RSI at 40.3 and Dow RSI at 34.2 are approaching levels that historically precede mean-reversion bounces — but the macro backdrop needs to cooperate first.
Key Economic Events Wednesday
| Time (ET) | Event | Prior | Estimate | Why It Matters |
|---|---|---|---|---|
| 9:30 AM | Challenger Job Cuts (Aug) | 33.4K | 62K est. | Layoff trend — labor market health check |
| 10:00 AM | ADP Employment Change (Aug) | 44K | 48K est. | NFP preview — key for Fed |
| 2:00 PM | ISM Services PMI (Aug) | 54.1 | 54.3 est. | High impact — prices sub-index 70.3 last month; another hot read re-ignites hike bets |
| 2:00 PM | Factory Orders MoM (Jul) | −0.3% | +0.7% est. | Manufacturing health; rebound expected |
| 2:30 PM | EIA Crude Oil Stocks Change | +0.1M | — | Oil supply read — critical given today's spike |
| 6:00 PM | Fed Beige Book | — | — | Regional economic conditions — watch for inflation language |
| AMC | AVGO Earnings (est. EPS $3.30) | — | — | Biggest earnings event of the week — AI/semi read-through |
| AMC | SNOW, HPE, NTAP, FIVE, WOOF, GOLD | — | — | Cloud, storage, retail, gold miner reporting |
Bull Case for Wednesday
- DELL/PANW/MDB AMC beats lift tech sentiment at the open.
- ISM Services comes in at or below estimate — takes some rate-hike pressure off.
- Oil gives back some of today's spike on diplomatic signals or supply data.
- SPX bounces off 50-DMA support at 7,566 — technical mean-reversion trade.
Bear Case for Wednesday
- ISM Services Prices sub-index stays hot (was 70.3) — confirms inflation re-acceleration.
- ADP prints weak — mixed signal (weak jobs = fewer hikes but also weaker growth).
- Oil holds above $90 or pushes higher on further Hormuz news.
- AVGO misses after close — negative read-through for entire semi/AI complex.
Key Levels for Wednesday
| Index | Support | Resistance | Key MA | Next-Session Lean |
|---|---|---|---|---|
| SPX | 7,566 (50-DMA) | 7,712 (20-DMA) | 50-DMA 7,566 | Cautious — hold 50-DMA or it gets ugly |
| NDX | 25,950 (50-DMA) | 26,397 (20-DMA) | 50-DMA 25,950 | AMC beats may stabilize; still below 20-DMA |
| RUT | 2,833 (swing low) | 2,990 (50-DMA) | 50-DMA 2,990 | Bearish — RSI 33, both MAs overhead |
| DJI | 52,344 (pivot) | 52,813 (50-DMA) | 50-DMA 52,813 | RSI 34 — bouncy but rate-challenged |
Overnight risk: Geopolitical headlines from the Middle East could move oil — and therefore the whole rate / inflation complex — before Wednesday's open. Set alerts on WTI.
Here's what today actually told us. The market had been grinding higher on the assumption that the Fed was done. One oil shock — one afternoon of Hormuz headlines — and the rate-hike trade is back at 60% odds on Kalshi. That's how fast the narrative can flip. The session wasn't really about stocks; it was about the oil market repricing the entire inflation path, and equities just had to deal with it.
The mindset going into tomorrow is this: don't chase the AMC earnings bounce in premarket. DELL up 11%, MDB strong, GTLB strong — great results, but the macro headwind hasn't changed. You get a gap-up open, and then the ISM Services data hits at 10 AM. If prices stay hot, you could give back everything and more. Let the trade come to you. If the market opens strong on earnings enthusiasm, that's a gift — wait to see whether it holds past the macro data before committing size.
The one thing I'm watching most closely: AVGO after the close Wednesday. Broadcom is at an 84th-percentile IV rank with earnings due — the options market is pricing a big move. That report is a referendum on AI infrastructure spending. A beat with strong guidance holds the AI trade together. A miss or soft guidance reopens the AI rotation story. Everything in tech hinges on it for the rest of the week. Manage your position size going in. Be the house, not the gambler.
What Today Means
The market closed on a risk-off note driven by an oil shock that simultaneously reignited inflation fears, pushed the 10-year yield to its 2026 high, and forced the re-pricing of Fed policy from "hold" to "possible September hike." The underlying equity earnings tape — PANW, MDB, GTLB, DELL, CRDO, SAIC — is actually quite healthy. The earnings story is bullish. The macro overlay is the problem.
What to Watch Overnight / Tomorrow
- Oil: Any de-escalation in the Middle East or a diplomatic signal on Hormuz could take $3–5 off WTI and immediately ease rate-hike fears. Set a WTI alert at $88 and $87.
- DELL after-hours confirmation: Multiple dark-pool prints and the +11% move need to hold — watch pre-market action. The guidance raise was meaningful.
- ISM Services PMI (10 AM Wednesday): Prices sub-index was 70.3 last month. If it stays above 68, markets will re-price another 25 bps hike. If it cools, the tape can breathe.
- MRNA dark pool print ($11.4M): Unexplained large institutional buy. Monitor for overnight news catalyst.
- AVGO Wednesday AMC: The definitive read on AI infrastructure spending this week.
Three Takeaways
- The earnings season is strong — the macro backdrop is the risk. Don't let one set of data points override the other. Both are true simultaneously.
- Energy (XLE) is the clear sector rotation trade while oil holds above $88–$90. CRK, energy services, and tanker names (PXS) are direct beneficiaries. Confirm your stop levels before sizing up.
- Tech needs AVGO to hold the line Wednesday night. If Broadcom guides conservatively, the AI rotation risk becomes a larger conversation. If it beats and guides up, AMC beats from PANW/MDB/DELL re-anchor tech sentiment.
Trade smart. Manage risk. Let the probabilities work for you.
- Post-market edition
- This report recaps the session that just closed and sets up the next trading day. All index prices and % changes are official closing figures unless marked AMC (after market close).
- Earnings verification
- Every earnings row is cross-checked against two sources (Finnhub + FMP). If sources conflict, the row is marked unconfirmed — verify and no actuals are stated.
- IV percentile
- Implied volatility (IV) rank — how today's IV compares to the past year. High IV = expensive options (favor selling); Low IV = cheap options (favor buying).
- Dark pool / flow alerts
- Large institutional block trades executed off-exchange. They confirm directional conviction but are not always predictive — they are one data point, not a signal alone.
- GEX (gamma exposure)
- Measures market-maker hedging pressure. Negative GEX near a price level means market makers are short gamma and amplify moves — explaining today's afternoon volatility spike.
- Color language
- Green = bullish / beat / long · Red = bearish / miss / avoid · Amber = caution / unconfirmed / watch · Grey = neutral
