Scoreboard
Growth and surprise figures are what a score alone can’t show — shown beside every name so a SKIP tag, or a non-earnings catalyst call, is auditable, not just asserted. “EPS gr” here is trailing fiscal-year growth from the screener feed, not quarter-over-quarter — today’s two fresh-EP names (Nu, Sigma Lithium) aren’t yet in the table this skill normally pulls QoQ figures from. No Close column: this is a premarket run, no regular session has happened yet.
Situational Awareness
🏆 A fourth straight week of gains, on cooling inflation. The S&P 500 closed at a record high Thursday, clearing 7,800 for the first time, as softer CPI reinforced bets the Fed holds rates through year-end. Futures were mixed into Friday’s open.
🤖 This week’s AI-capex season wrapped up strong but selective. Meta budgeted $115–135B of 2026 capex and beat estimates; Applied Materials raised its 2026 equipment-growth outlook above 30%. But the reaction split on margin sensitivity — Cisco fell 6.1% despite record revenue on margin-pressure concerns, and Cerebras Systems tumbled 14% on a genuine revenue miss ($180M vs. $194M consensus). The capex story is intact; not every name riding it is being rewarded the same way.
🔁 Reddit joins the S&P 500 before the open on Tuesday, August 18, replacing AvalonBay Communities (being acquired by Equity Residential). Mechanical index-fund buying ahead of the effective date — see Top Calls for the name-specific detail, including a Google AI-search-traffic crosscurrent worth watching into the inclusion date.
📈 A busy IPO week — roughly 44 pricings Monday through Thursday — adds float and sector noise into an already news-dense week; no single listing stood out as a market mover as of this run.
Bellwether Watch
SNDK
HoldingAI-storage/memory leadership theme confirmed hard: FY2026 revenue +175% YoY to $20.25B, Data Center revenue +437% YoY, and a new FY2028–2030 framework (mid-to-high-teens revenue growth, ~80% gross margin, ~75% operating margin, ~50% FCF margin) unveiled at Thursday’s Investor Day. Stock ran ~14–19% Thursday and is still up 6.7% today — day-2 confirmation that the market is treating this as durable, not a one-day pop.
Top Calls
$VERA +24.2% · FDA approval, regulatory · High — the FDA granted accelerated approval to TRUTAKNA (atacicept) for IgA nephropathy, a potentially life-threatening kidney disease with no directly competing approved therapy. Same-day analyst moves: Raymond James raised its target to $84 (from $78), BofA Securities and Jefferies both reiterated Buy. The +24% reflects the market repricing a de-risked, now-approved asset.
$SNDK +6.7% (day 2) · bellwether, investor day · High — SanDisk’s Aug 13 Investor Day set FY2028–2030 targets (mid-to-high-teens revenue growth, ~80% gross margin, ~75% operating margin, ~50% FCF margin) on top of FY2026 results already showing 175% revenue growth and 437% Data Center revenue growth YoY. Ran ~14–19% Thursday, still +6.7% today — the largest AI-storage story of the week by market cap ($241B).
$RDDT +10.4% · index inclusion · High — S&P Dow Jones Indices announced 8/13 that Reddit joins the S&P 500 before the open on 8/18, replacing AvalonBay Communities. Index funds must mechanically buy ahead of the effective date. Some coverage flagged Google AI-search-traffic concerns as a real crosscurrent to watch into inclusion day.
$NU +11.1% · fresh-EP, vol-gated · Med — Nu Holdings posted a record Q2: net income $1.06B (+49% YoY, ROE 33%), gross revenue ~$5.9B (+39% YoY), ~4M customers added to reach 139M total. EPS surprise +12.55%, revenue surprise +9.10%. SKIP-tagged on the engine’s premarket volume gate — a known structural limit, not a verdict on the print.
$SGML +10.0% · fresh-EP, vol-gated · Low–Med — Q2 production beat guidance by 6% (35,000t; H1 total 58,000t, above target) on a mining-upgrade execution. The financial-statement surprise columns (EPS −15.48%, revenue −0.63%) show a miss against consensus despite the operational beat — a genuinely mixed print, not a clean one.
$UMAC +14.6% · r10 absorption · Low–Med — still running 6 trading days after an Aug 6 print that beat revenue by 81.87% (+687% YoY). No distinct catalyst found for today specifically; Roth MKM reiterated Buy Aug 11 on favorable US drone policy, part of a broader group move.
$AEHR +8.4% · r10 absorption · Low — extending a run that started Aug 11 (swing to a fiscal Q4 profit, record $60.7M bookings, FY27 revenue guide +160–200% on AI-testing demand). No fresh company-specific news found for today; read as continued momentum, not a new catalyst.
$CHRN +9.0% · sector sympathy · Low — an AI-compute infrastructure name (Applied Digital subsidiary); no distinct catalyst identified for today. Valuation is rich (P/S ~45x vs. a ~3.4x peer group), worth flagging alongside the move.
$DFH +8.2% · sector sympathy · Low — no DFH-specific news found for today. Homebuilders as a group tend to catch a bid on cooling-rate-cut expectations, this week’s dominant macro theme, but this report can’t confirm that’s the actual driver behind today’s move.
$BRUN · watch, report pending — Q2 2026 results are due pre-market today with an 8am ET call essentially concurrent with this run. Premarket has run up +15.3% ahead of the print; the surprise-data columns in the screener feed reflect BRUN’s prior reported quarter, not today’s release, and are genuinely unconfirmed until the release is out.
SanDisk (SNDK): What Was Said at Investor Day
SanDisk held its 2026 Investor Day on Thursday, August 13, with presentations from Chairman and CEO David Goeckeler, CFO Luis Visoso, and other members of the leadership team.
The financial targets, for fiscal 2028 through fiscal 2030:
Revenue growth in the mid-to-high teens annually, roughly tracking the growth in storage capacity SanDisk ships
Non-GAAP gross margin of approximately 80%
Non-GAAP operating margin of approximately 75%
Operating expenses held to roughly 5% of revenue
Adjusted free cash flow margin of approximately 50%
A commitment to return 100% of cash generated beyond what the business needs back to shareholders
The market opportunity behind those targets. CFO Luis Visoso told investors the NAND market overall will pass $300 billion in 2026 and $500 billion in 2027, with demand continuing to outpace SanDisk’s own supply, and industry output staying tight into 2028. Management’s specific bet for SanDisk: the addressable market for enterprise data-center flash memory reaches 1.2 zettabytes by 2030, as AI shifts from training toward inference.
The customer commitments underpinning the growth story. SanDisk has signed what it calls “New Business Model” agreements with major customers — contracts with committed volumes and minimum financial guarantees. Coverage of the investor day put the count at 8 customers, covering roughly half of SanDisk’s expected bit output in fiscal 2027 and about two-thirds in fiscal 2028.
The technology roadmap. SanDisk’s newest NAND flash chip, BiCS10, is sampling to customers now, described as the highest-density memory chip on the market, delivering more than 60% higher bit density and roughly 75% better power efficiency than the prior generation, BiCS8. A related product, BiCS9, combines the proven BiCS8 memory array with BiCS10’s more advanced manufacturing process — management’s way of getting some of the new generation’s cost benefits into products faster without a full technology changeover. Further out, SanDisk is developing “High-Bandwidth Flash,” a new memory category aimed at AI workloads’ data-bandwidth bottlenecks; the company says the first design has been completed and sent to manufacturing (“taped out”), with customer sampling planned for next year.
Quote from the CEO, at the investor day: “Our strong performance today is the direct result of disciplined execution against the strategy we outlined 18 months ago,” Goeckeler told investors.
What the numbers underneath this look like, from SanDisk’s own August 5 earnings release: fiscal 2026 revenue was $20.25 billion, up 175% from the prior year, with data-center revenue specifically up 437% to $5.15 billion. Fourth-quarter revenue alone was $8.97 billion, up 51% from the prior quarter, with gross margin at 84.6%. Full-year GAAP net income was $11.43 billion. The company’s board also approved an additional $14 billion in stock buybacks, bringing total remaining authorization to $15.5 billion. Guidance for the first quarter of fiscal 2027 (SanDisk’s next scheduled report) calls for revenue of $10.3–10.8 billion — another large sequential jump if it holds. Separately, the earnings release disclosed 10 total “New Business Model” agreements signed to date (5 announced on the April earnings call, 5 more since: 3 with new customers, 2 expanding existing agreements) — a related but not identical count to the “8 customers” figure from investor-day coverage.
One qualifier worth including. Not every reaction was pure enthusiasm on the numbers alone. At least one analyst (KC Rajkumar of Lynx Equity Strategies) noted a nuance in the bit-growth math: SanDisk’s own manufacturing-efficiency gains (roughly 54% average bit-productivity improvement per NAND generation transition) could let actual output growth run ahead of the mid-to-high-teens revenue target during certain periods. That’s a technical point about how the model works, not a challenge to the targets themselves.
Shares rose roughly 12–14% Thursday (as much as 19% measured off the day’s intraday low) and continued climbing Friday, still up nearly 7% on top of that as this report went out. The move wasn’t confined to SanDisk: Micron rose 6%, Western Digital 8%, and SK Hynix 8% the same day, as investors treated the day as a read on AI-driven memory demand broadly, not just SanDisk’s own execution.
The Setups
$VERA
The FDA granted accelerated approval to TRUTAKNA (atacicept) for IgA nephropathy, a progressive kidney disease that can lead to dialysis or transplant, with no other approved therapy directly competing on the same mechanism. The approval converts a pipeline asset into a commercial one overnight — the kind of binary regulatory unlock that resets the addressable market in a single session. Same-day sell-side reaction was uniformly positive: Raymond James raised its target to $84, Jefferies and BofA both reiterated Buy. The +24% move reflects the market pricing in a de-risked, revenue-generating asset where before there was approval risk.
$RDDT
S&P Dow Jones Indices announced Thursday that Reddit will join the S&P 500 before the open on August 18, replacing AvalonBay Communities (which is being acquired by Equity Residential). Index funds tracking the S&P 500 are mechanically required to buy shares ahead of the effective date — a forced-buyer dynamic distinct from any change in the underlying business. Shares rose roughly 11% after-hours on the announcement and are continuing to run in Friday’s premarket. One crosscurrent flagged in coverage: Google’s AI-generated search summaries have been cited as a traffic-diversion risk for content platforms including Reddit, worth watching as the inclusion date approaches.
$NU
Nu Holdings posted a record Q2 2026: net income of $1.06B, up 49% YoY, with ROE at 33%. Gross revenue reached nearly $5.9B, up 39% YoY, and gross profit rose 43% to $2.44B. The company added roughly 4 million customers in the quarter to reach 139 million total across Brazil (118M), Mexico (15.8M), and Colombia (5M+). The efficiency ratio ticked up from Q1 on marketing, real-estate, and international-expansion spend — the one line worth watching, though it’s an investment-driven increase, not a cost-control miss. EPS surprise +12.55%, revenue surprise +9.10%. The scoring engine’s SKIP tag here is a premarket volume-gate artifact (relative volume can’t clear a 2.0x bar before the open), not a read on the quality of the print.
$SGML
Sigma Lithium’s Q2 2026 production came in at 35,000 tonnes of high-grade lithium concentrate, 6% above its own guidance, with H1 total of 58,000 tonnes also above target — the company credits a mining-upgrade execution following the primarization of its operations. That’s a genuine operational beat. But the screener’s financial-surprise columns show the opposite on the numbers that actually reached the income statement: EPS surprise −15.48%, revenue surprise −0.63%, both misses against consensus. The stock’s +10% premarket move appears to be trading the production story; the financial miss is the detail an operator should have in hand before treating this as a clean beat.
$UMAC / $AEHR
Both names are extending moves from earnings that are now several trading days old rather than reacting to anything fresh today. Unusual Machines beat revenue by 81.87% (+687% YoY) on Aug 6 and has continued climbing on drone-sector policy tailwinds (Roth MKM reiterated Buy Aug 11). Aehr Test Systems swung to a fiscal Q4 profit on Aug 11 with record $60.7M bookings and a FY27 revenue guide of +160–200% on AI-testing demand, and has kept running since (all-time high Aug 12). Neither has a distinct catalyst identified for today specifically — both read as continued absorption of a real print rather than new information.
$CHRN / $DFH
Neither name has a distinct, sourced catalyst for today. ChronoScale Holdings (an AI-compute infrastructure subsidiary of Applied Digital) is likely riding this week’s broader AI-infra capex momentum; its valuation is rich at roughly 45x P/S against a ~3.4x peer group, worth keeping in view alongside the move. Dream Finders Homes has no DFH-specific news found for today — homebuilders broadly tend to catch a bid on cooling-rate-cut expectations, this week’s dominant macro theme, but this report can’t confirm that link for DFH specifically rather than asserting it.
$BRUN
Boost Run’s Q2 2026 results are scheduled for release pre-market today with an 8am ET conference call — essentially concurrent with this run. As of this snapshot the release had not yet been located, and the screener’s EPS/revenue-surprise columns reflect the company’s prior reported quarter, not today’s. Premarket has run up +15.3% ahead of the print. Treat as unconfirmed until the actual Q2 numbers are out.
Bottom line
Highest-conviction setup on the board: $VERA — a first-in-class FDA approval with no directly competing approved therapy. Largest story by market cap: $SNDK, whose Investor Day re-rate is still confirming on day 2.
$NU and $SGML both beat on real, filing-referenced metrics but are SKIP-tagged on the scoring engine’s premarket volume gate — pending 9:30 confirmation, not a verdict on either print.
