Stock Market Today: CPI Cools to 3.4%, Tech Leads — Aug 12

Wednesday, August 12, 2026 · 8:45 AM ET · MTC Market Intelligence

MTC Premarket Brief Wednesday, August 12, 2026

The number the whole tape was waiting on just landed, and it cooled. July CPI printed 3.4% year over year at 8:30 AM ET — matching expectations and easing from June’s 3.5% — and the market exhaled. Futures flipped from flat to firm: S&P +0.4%, Nasdaq-100 +0.8% leading, Dow +0.2%. That’s a classic relief-rally shape — growth and tech out front the moment the inflation fear gets a little smaller. Remember where we came from: Tuesday the S&P slipped 0.3% to close at 7,728, the Nasdaq lagged at 26,445 (-0.6%), and the Dow eased to 53,792 as the US-Iran Hormuz standoff kept oil bid and nerves up into the print. This morning the print did its job — it took the worst-case hot read off the table. VIX is calm at 15.55, and the relief is real. But here’s the honest part: cooler is not cold. Inflation at 3.4% is still well above the Fed’s 2% target, and this is a hike-risk regime, not a cut one — Kevin Warsh’s Fed has been openly split on whether to RAISE in September, and CME odds were still near a coin-flip a week ago. What pulled those odds down was the weak jobs print (-23,000), and now a cooperative CPI adds to that. So the relief has a basis. What it doesn’t have yet is confirmation. Oil is still firm at $82.13 with the Strait of Hormuz unresolved, and the 10-year is elevated near 4.71% — the two things that can put the hike camp right back in the conversation. Under the index it’s an AI-earnings tape: Lumentum (LITE) is jumping on a Q4 blowout driven by AI optical demand, Sandisk (SNDK) is up 4%+ on AI storage, and CAVA popped on a clean Q2 beat. SPX sits with 7,760 overhead as the reclaim line and 7,700 as the floor that has to hold. Clear 7,760 and the highs are back in play; lose 7,700 and the relief fades toward 7,660. Don’t confuse a cooler print with an all-clear. Trade the reaction at the level, watch the 10-year, and let the market prove the relief is real before you chase it.

InstrumentLevelChangeNote
S&P 500 (prior close)7,728.20-0.3%Slipped Tuesday into the CPI print as oil stayed firm and nerves built. This morning the cooler number flips the read — futures point higher and the reclaim of 7,760 is back in play. The record zone is right overhead; the level, not the relief, decides whether it gets reclaimed on the open.
Nasdaq Composite (prior close)26,445.45-0.6%Tuesday’s laggard, down as tech cooled ahead of the number. This morning it flips to the leader — Nasdaq-100 futures +0.8% — because a softer CPI is exactly what rate-sensitive growth wanted. Watch whether that leadership holds through the cash open or fades once the relief is priced.
Dow (prior close)53,791.85-0.3%Eased Tuesday with the broad tape, shedding 184 points. This morning it’s the quiet participant, up about 0.2% — the value-and-cyclical side taking part in the relief but not leading it. On a cooler-CPI day the growth names get the first bid; the Dow follows, it doesn’t drive.
S&P 500 Futures+0.4%Green after the print — the relief in action. A firm gap the morning after CPI cooled says the tape got the read it wanted and is willing to lean in. But +0.4% is measured, not euphoric: real conviction shows up if the cash session holds the gains, not just opens on them.
Nasdaq-100 Futures+0.8%The clear leader — growth snapping to the front the moment inflation fear shrinks. Doubling the S&P’s gain is the textbook cooler-CPI response, and the AI-earnings movers underneath are adding fuel. The size is the tell: this is where the relief is concentrated. Watch it hold or fade into the open.
VIX15.55steadyCalm and holding low as the print removed the worst-case tail. A settled VIX the morning after a cooperative CPI is the market saying the immediate fear is gone. Low absolute level is comfort — but comfort into a still-firm oil tape and elevated yields is exactly when discipline matters most.
WTI Crude82.13firmStill the wildcard the CPI can’t retire. Crude is holding elevated with the US-Iran Strait of Hormuz standoff unresolved — the one input that keeps the inflation story, and the Fed’s hike camp, alive even after a cooler print. Firm oil is the reason today’s relief isn’t a full all-clear.
10-Yr Yield4.71%watchElevated near a monthly high even as CPI cooled — the tell to watch. If the print were a true all-clear, yields would ease; instead they’re holding up, which says the bond market isn’t fully sold on the relief. Watch the 10-year first — it tells you whether the equity bounce has real backing.
Bitcoin64,300steadyHolding near $64K as risk appetite firmed on the cooler print. Constructive but not leading — resistance still sits up near the $67K zone where prior rallies stalled. A steadier tone than Tuesday, tracking the relief without driving it. Watch whether it can build on the risk-on shift or stalls again.

Overnight & Global Markets

The morning turns on one number, and it cooperated. July CPI printed 3.4% year over year at 8:30 AM ET, in line with expectations and down from June’s 3.5%, and the tape flipped from cautious to relieved: S&P futures +0.4%, Nasdaq-100 +0.8% leading, Dow +0.2%. That shape — growth out front the moment the inflation read softens — is the classic relief response. Rewind one day: Tuesday the S&P eased 0.3% to 7,728, the Nasdaq lagged at 26,445, and the Dow slipped to 53,792 as the US-Iran Hormuz standoff kept oil bid and the market braced for the print. This morning the print did its job — it took the hot-CPI tail risk off the table, and VIX sits calm at 15.55. But the regime underneath hasn’t flipped. This is still a hike-risk Fed: Kevin Warsh’s committee has been openly split on whether to RAISE in September, and CME odds were near a coin flip a week ago before soft jobs (-23,000) pulled them down. A cooler CPI adds to that easing, but it doesn’t end the debate — because oil is still firm at $82.13 with Hormuz unresolved, and the 10-year is holding elevated near 4.71%. Those two are the honest counterweight to the equity relief: if the print were a genuine all-clear, yields would be falling, not holding a monthly high. Under the index it’s an AI-earnings tape doing the heavy lifting — Lumentum (LITE) jumping on a Q4 blowout on AI optical demand, Sandisk (SNDK) up 4%+ on AI storage, CAVA popping on a Q2 beat. The takeaway: the relief is real and it has a basis, but it isn’t confirmation. SPX holds the story between 7,760 overhead and 7,700 below. Trade the reaction at the level, watch the 10-year, and let the market prove the bounce before you chase it.

MAJOR HEADLINES AND CATALYSTS

Top Premarket Stories

  • July CPI cooled to 3.4% year over year at 8:30 AM ET — in line with expectations and down from June’s 3.5% — and the tape flipped green: S&P futures +0.4%, Nasdaq-100 +0.8% leading, Dow +0.2%. The softer print took the hot-CPI tail risk off the table and put rate-sensitive growth back in front. The relief is real; whether it holds through the cash session is the day’s question.
  • The regime is still hike-risk, not cut. Kevin Warsh’s Fed has been openly split on whether to RAISE rates in September, and CME odds were near a coin flip a week ago before soft jobs (-23,000) pulled them down. A cooler CPI adds to that easing — but at 3.4% inflation is still well above the 2% target. Cooler is not cold, and the September debate isn’t over.
  • Oil is the wildcard the print couldn’t retire. WTI is holding firm at $82.13 with the US-Iran Strait of Hormuz standoff still unresolved — the one input that keeps the inflation story, and the Fed’s hike camp, alive even on a cooler-CPI morning. Watch the Hormuz headlines; a sharp oil move is the thing that can undo today’s relief before it’s confirmed.

Stock-Specific

  • The AI-earnings movers are carrying the tape. Lumentum (LITE) is jumping premarket after a Q4 blowout driven by massive AI optical demand, and Sandisk (SNDK) is up 4%+ on AI storage signals — both real earnings catalysts, not sentiment pops. On a cooler-CPI relief day, these are the names compounding the tech bid. The AI capex theme is still getting paid.
  • Consumer and small-cap earnings are adding movers too. CAVA popped after Q2 revenue hit $368.4M with an EPS beat, Owlet (OWLT) surged roughly 10% on its report, and Trimble (TRMB) rose ~2.2% on Q2 results. A stock-picker’s morning underneath a macro-driven index — single names moving on their own numbers while the tape digests CPI.

Global and Macro

  • CPI is behind us; the read now shifts to what it means for September. With inflation at 3.4% and still above target, a cooler print eases the immediate hike fear but doesn’t settle the FOMC’s Sept 15-16 decision. The market will parse core CPI, Fed-speak, and the 10-year for the real signal. Today’s relief is the first reaction, not the final word on the rate path.
  • Cross-asset tone firmed but didn’t fully confirm: VIX calm at 15.55, Bitcoin steady near $64K, futures green — yet oil holds $82.13 and the 10-year sits near 4.71%. The equity screen says relief; bonds and crude are only half-agreeing. Same print, two messages — the stock tape leaning risk-on while yields and oil keep the inflation question open.

TECHNICAL ANALYSIS

S&P 500 Key Levels

  • SPX 7,760 is the reclaim line. Tuesday closed 7,728, and with futures +0.4% the open points right at this first resistance back into the record zone. Clear and hold 7,760 in the cash session and the highs are back in play with room toward 7,780+. Until it goes, treat the relief bounce as unconfirmed — an opening gap into resistance still has to prove it can hold.
  • SPX 7,700 is the line that has to hold. It’s the round-number floor just under Tuesday’s close and the level that keeps the relief structure intact. Hold it and the cooler-CPI bounce stays constructive. Lose 7,700 and the relief starts to fade — the first sign the market is fading the print rather than trusting it, especially with oil firm and yields elevated.
  • Below, 7,660 is the downside checkpoint. It’s where a real fade of the relief would find its next test and where the bounce would officially be in question. On a day the tape is trying to turn a cooler print into follow-through, losing 7,700 is the warning and a break of 7,660 is the confirmation the relief didn’t stick. Watch it if the open can’t hold its gains.

Sector and Sentiment

  • Leadership tell: Nasdaq-100 +0.8% versus Dow +0.2%, with AI-hardware names (LITE, SNDK) leading under the surface. Growth out front by a wide margin is the healthy cooler-CPI shape — if that leadership holds into the open, the relief has legs. If tech fades back toward the Dow’s pace, the bounce was a gap-fill of fear, not a real risk-on turn.
  • Sentiment tell: VIX calm at 15.55 but the 10-year holding near 4.71%. Low volatility plus a bond market that won’t ease is the subtle disagreement to respect. The equity screen is comfortable; the yield tape is not fully on board. Calm VIX on a relief morning is a reason to trade the level with discipline, not to assume the all-clear is complete.

TODAY’S ECONOMIC CALENDAR

Key Releases (ET)

  • The marquee event already hit: July CPI at 8:30 AM ET came in at 3.4%, cooling from 3.5% and matching expectations. That’s the number that set the morning’s tone. From here, watch Fed-speak and the 10-year off 4.71% as the real-time read on how the September hike debate is leaning now that the inflation data is in hand. PPI and jobless claims are the next data checkpoints.
  • The subplot is still oil. With the US and Iran unresolved over a Strait of Hormuz reopening, any concrete headline swings crude — and crude is the inflation input the cooler CPI couldn’t neutralize. WTI at $82.13 shows it’s still firm. A sharp oil move is the one thing capable of pulling the hike camp back into the conversation even after a cooperative print.

Earnings Today

  • The AI names dominate the premarket movers: Lumentum (LITE) jumping on an AI-optical Q4 blowout, Sandisk (SNDK) up 4%+ on AI storage, CAVA popping on a Q2 beat. After the close, Cisco (CSCO) reports fiscal Q4 (EPS ~$1.17 est on ~$16.83B revenue) and Cerebras (CBRS) delivers its first look as a newer AI-compute name — both worth watching for the AI-demand read into tomorrow.
  • With earnings season winding down, the macro is back in the driver’s seat, but today’s slate still offers clean single-name setups — AI hardware and strong consumer beats getting paid, any cautious guidance getting sold. Trade the individual stories on their own merit; the index is taking its cue from CPI and the 10-year, not from any one earnings line today.

PREMARKET PLAYBOOK

Key Levels

  • SPX 7,760 — the reclaim line. Tuesday closed 7,728, and with futures +0.4% the open points right at this first resistance in the record zone. Clear and hold 7,760 in the cash session and the highs come back into play toward 7,780+. Until it goes, the relief bounce is unproven — react to the reclaim and hold, don’t chase the opening gap into resistance.
  • SPX 7,700 — the line that has to hold. The round-number floor just under Tuesday’s close that keeps the cooler-CPI relief intact. Hold it and the bounce stays constructive. Lose 7,700 and the relief fades — the first sign the tape is fading the print rather than trusting it, with oil firm and the 10-year elevated overhead. This is the level that tells you if the bounce is real.
  • SPX 7,660 — the downside checkpoint. Where a real fade of the relief finds its next test and the bounce is officially in question. Losing 7,700 is the warning; a break of 7,660 is the confirmation the cooler print didn’t stick. On a day the market is trying to turn relief into follow-through, this is the line that says it failed.

Bull case: The cooler CPI holds the narrative: rate-sensitive growth leads, the AI-earnings movers (LITE, SNDK) keep the tech bid alive, and SPX clears and holds 7,760 to put the record highs back in play toward 7,780+. Oil headlines stay quiet, the 10-year eases off 4.71% as the market accepts the softer inflation read, and the relief turns into real follow-through. Calm VIX plus a settling bond market lets the bounce build into a trend rather than a one-day gap.

Bear case: The relief proves shallow: the opening gap into 7,760 fails to hold, oil spikes on a Hormuz headline, and the 10-year climbs further off 4.71% as the hike camp reasserts that 3.4% is still above target. SPX loses 7,700, the cooler-CPI bounce fades toward 7,660, and the market treats the print as not-cold-enough. Firm crude and sticky yields expose an extended tape with earnings season nearly done and little left to lean on but the macro.

Premarket Movers

Premarket gainers and laggards Wednesday, August 12, 2026
Today’s premarket gainers and laggards.

Gainers

LITELumentumAI optical beatLeading the movers on a Q4 blowout driven by AI optical demand — a real fundamental catalyst, not a low-float pop. The standout name on an AI-earnings morning and the clearest expression of the data-center capex theme. Quality beat, but the premarket size means the chase-risk is real; trade the reaction, not the gap.
SNDKSandisk+4%Up 4%+ on AI storage demand signals — the memory-and-storage leg of the same AI-capex wave lifting the optical names. A second confirming mover rather than an isolated pop, which is what gives the AI theme credibility this morning. Strong storage results are the kind of underneath-the-index leadership a relief day wants.
CAVACAVA GroupbeatSurging after Q2 revenue hit $368.4M with an EPS beat — a clean consumer-growth win outside the AI story. Proof the strength isn’t only in tech, and a name that gets paid on execution. The read is whether the pop holds through the session or fades as the broader relief gets priced in.

Laggards

GOOGLAlphabetweak into the printSank in the prior session as megacap tech cooled ahead of CPI — a reminder that even leadership names faded into the number. Worth watching whether the cooler print pulls it back with the Nasdaq bid this morning or it keeps lagging. A relief-day laggard to track, not a fundamental break.

Risks Into the Open

  • Primary risk: reading the cooler CPI as an all-clear. Inflation at 3.4% is still above the Fed’s 2% target, and this is a hike-risk regime under Kevin Warsh — a softer print eases the September debate but doesn’t end it. The danger is chasing the relief bounce as if the rate path is settled. Watch the 10-year off 4.71% as the early tell; yields that won’t ease say the bond market isn’t calling all-clear.
  • Secondary risk: an oil shock from Hormuz. The US and Iran remain unresolved over a Strait of Hormuz reopening, and WTI is holding firm at $82.13. A sharp crude spike puts inflation — and the Fed’s hike camp — right back in the conversation even after a cooperative CPI. It’s the one input the print couldn’t neutralize, and the single headline most capable of undoing today’s relief before it confirms.
  • Tertiary risk: chasing the AI-earnings movers into the gap. LITE, SNDK, and CAVA are real beats, but premarket pops of this size cut both ways — the same momentum that powers the gap can reverse it once the relief is priced. On a macro-driven day, single names can move violently on their own stories. Size for the volatility, trade the reaction at the level, and don’t confuse a strong print with a clean entry.
