- MVIS -18.92% was the single biggest move across all cap tiers — led the downside on the small-cap tier.
- Two-way tape — 4 cap tiers had an up-mover and 4 had a down-mover.
- Spread between the biggest up and biggest down move was 29.7 percentage points — wide dispersion.
These are the biggest stock movers from Thursday’s US session (August 13, 2026) — one up and one down for each market-cap tier. MVIS -18.92% led overall in the small-cap bucket. Each ticker block has the catalyst (or an honest “no clear catalyst” if there isn’t one) plus what a pattern-recognition algorithm would actually flag in the move — base breakout, momentum continuation, failed breakdown, sympathy selloff, or noise.
Mega-cap movers (Companies above $200B)
↑ NFLX +5.43%
$78.24 · Mega-cap · $3.1B traded
Why: Bill Ackman disclosed a new Netflix position four years after selling at a loss, adding momentum to a broad rally driven by cooler-than-expected inflation data boosting rate-cut hopes.
Pattern: Heavy dollar volume on a gap-up day — momentum continuation within an existing uptrend rather than a base breakout, so chasers here face elevated mean-reversion risk near highs.
↓ TMO -1.18%
$595.89 · Mega-cap · $626M traded
Why: Thermo Fisher closed a $1.1B sale of its microbiology unit to a private equity firm, and the stock drifted lower on a day when the broad market rallied without it.
Pattern: Modest down day on average volume — looks like digestion noise rather than a clean pattern break, with the stock still range-bound near recent levels.
Large-cap movers ($10B to $200B)
↑ INTU +7.04%
$358.29 · Large-cap · $1.6B traded
Why: Intuit surged after expanding its conversational AI platform across mid-market finance, with investors positioning ahead of the August 25 earnings date and the broader AI narrative lifting sentiment.
Pattern: Strong +7% move on elevated dollar volume suggests a momentum thrust out of a consolidation zone — worth watching whether it holds above the breakout level into earnings.
↓ CSCO -8.40%
$113.47 · Large-cap · $6.9B traded
Why: Cisco dropped over 8% on massive $6.9B dollar volume — likely a post-earnings selloff given the outsized volume and sharp decline on a day the broader market hit record highs.
Pattern: High-volume gap-down against a rising market is a failed-breakout signal — earnings-driven drops of this magnitude in mega-names typically see follow-through selling before any base forms.
Mid-cap movers ($2B to $10B)
↑ ASAN +9.79%
$9.87 · Mid-cap · $70M traded
Why: No clear single catalyst — Asana rallied nearly 10% amid broad small-cap and growth-stock strength following the soft inflation print, with short-interest positioning likely amplifying the move.
Pattern: Sub-$10 stock with heavy short interest popping on a risk-on tape — classic short-squeeze candidate, but dollar volume at $70M is thin for sustained follow-through.
↓ FCEL -6.14%
$20.34 · Mid-cap · $151M traded
Why: No company-specific catalyst — FuelCell Energy dropped 6% as clean-energy names traded weak, with broader hydrogen/fuel-cell sentiment soft despite the risk-on macro backdrop.
Pattern: Continued downtrend move on moderate volume — no base formation visible, just lower-highs price action that looks like trend continuation rather than a washout capitulation.
Small-cap movers ($300M to $2B)
↑ ACHR +10.81%
$6.97 · Small-cap · $411M traded
Why: Archer Aviation extended its recent 45% monthly rally on continued eVTOL momentum, with sentiment lifted by Boeing-adjacent news flow and broad risk-on appetite from the inflation print.
Pattern: Momentum continuation on heavy $410M dollar volume for a small-cap — relative volume is well above average, but the stock is extended after a steep run and lacks a fresh base.
↓ MVIS -18.92%
$3.77 · Small-cap · $7M traded
Why: No clear catalyst — MicroVision dropped nearly 19% on very thin $7M dollar volume with no major headlines, suggesting a liquidity-driven selloff or block liquidation in a thinly traded name.
Pattern: Low-volume sharp decline in a sub-$5 stock is classic noise — without meaningful dollar volume this move is unreliable for pattern reads and likely reflects a single large seller.
