  • SHOP +16.98% was the single biggest move across all cap tiers — led the large-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 30.9 percentage points — wide dispersion.

These are the biggest stock movers from Wednesday’s US session (August 5, 2026) — one up and one down for each market-cap tier. SHOP +16.98% led overall in the large-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)

↑ LLY +4.86%

$1,169.86 · Mega-cap · $6.4B traded

Why: Eli Lilly surged after Q2 earnings blew past expectations on strong weight-loss and diabetes drug demand, prompting the company to raise full-year guidance.

Pattern: Gap-up on massive volume confirms the uptrend resumption after a multi-week consolidation — clean momentum continuation with buyers stepping in above prior resistance.

↓ AMD -7.04%

$482.05 · Mega-cap · $22.9B traded

Why: AMD sold off despite beating estimates as analysts called Q2 results ‘not exceptional’ and the market digested a capex-heavy forward outlook amid broader chip-sector rotation.

Pattern: Post-earnings gap-down on heavy volume looks like a failed breakout — stock was extended into the print and sellers used the report to take profits near highs.

Large-cap movers ($10B to $200B)

↑ SHOP +16.98%

$144.24 · Large-cap · $5.8B traded

Why: Shopify ripped nearly 17% after Q2 revenue topped estimates by $140 million, signaling e-commerce momentum is accelerating faster than the Street modeled.

Pattern: Massive earnings gap on roughly 3× normal dollar volume — classic breakaway gap from a base, the kind that tends to hold and become new support.

↓ PINS -8.68%

$23.36 · Large-cap · $494M traded

Why: Pinterest dropped nearly 9% despite beating Q2 estimates on AI-driven ad growth — likely a sell-the-news reaction as forward guidance or user metrics disappointed investors.

Pattern: Earnings gap-down through prior support on elevated volume suggests a breakdown from the recent range — watch for continuation selling into the mid-$20s floor.

Mid-cap movers ($2B to $10B)

↑ FUBO +11.62%

$10.66 · Mid-cap · $39M traded

Why: FuboTV jumped on renewed optimism around its streaming strategy after the CEO teased a November strategy reveal and highlighted strong North America subscriber growth.

Pattern: Rally on moderate volume from a low base — more of a speculative bounce than a clean technical breakout, needs follow-through to confirm a trend change.

↓ LCID -13.88%

$6.70 · Mid-cap · $142M traded

Why: Lucid crashed nearly 14% after reporting earnings that disappointed investors, compounded by news it delayed its more affordable EV model and announced a $1.4 billion cash overhaul.

Pattern: Post-earnings breakdown on heavy volume continues the longer-term downtrend — no base structure to speak of, just another leg lower in a persistent decline.

Small-cap movers ($300M to $2B)

↑ GLSI +0.28%

$14.39 · Small-cap · $1M traded

Why: No clear catalyst — GLSI was essentially flat on the session with minimal volume, landing here by default as the least-negative small-cap in the scan universe.

Pattern: Near-zero move on thin volume is pure noise — no pattern signal worth reading into, stock continues to trade in a low-liquidity sideways drift.

↓ MVIS -13.25%

$3.17 · Small-cap · $4M traded

Why: No clear catalyst in the headline flow — MicroVision’s 13% drop on modest volume looks like continued small-cap selling pressure amid broader risk-off sentiment.

Pattern: Steady grind lower without a defined base — this is trend continuation to the downside, not a capitulation flush, so no mean-reversion setup forming yet.
