These are the biggest stock movers from Friday’s US session (May 29, 2026) — one up and one down for each market-cap tier. SPCE +36.42% 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)

↑ ORCL +10.84%

$225.78 · Mega-cap · $8.7B traded

Why: Oracle rallied alongside Snowflake and ServiceNow as the AI infrastructure trade re-ignited, with traders rotating back into cloud names tied to enterprise AI workload growth.

Pattern: Clean momentum continuation on a mega-cap — double-digit single-day move on heavy $8.7B turnover suggests institutional accumulation, not retail noise.

↓ COST -3.91%

$956.32 · Mega-cap · $5.9B traded

Why: Costco slid with the broader consumer-staples tape in afternoon trade despite record fuel sales — no single-name catalyst, looks like sector rotation out of defensives.

Pattern: Mean-reversion pullback from extended highs — a -3.9% mega-cap day on $5.9B is sharp but lacks the gap-down pattern of an earnings or guidance miss.

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

↑ NOW +14.38%

$124.37 · Large-cap · $7.2B traded

Why: ServiceNow ripped higher in the same AI cloud bid that lifted Oracle and Snowflake, with traders treating the recent valuation reset as a buyable level.

Pattern: Looks like a failed-breakdown reversal — +14% on $7.2B turnover after a valuation reset is the classic squeeze-off-the-lows pattern, not noise.

↓ INTC -5.14%

$114.68 · Large-cap · $17.6B traded

Why: Intel fell as Computex 2026 headlines spotlighted Nvidia and AMD chip dominance, overshadowing the GOP-portfolio-flow story that had recently supported the stock.

Pattern: Momentum-reversal — heavy $17.6B turnover on a -5% day suggests distribution after the recent run, not a clean base; watch prior support level.

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

↑ ASAN +15.62%

$7.70 · Mid-cap · $146M traded

Why: Asana jumped after Q1 earnings highlighted strong revenue growth and raised guidance tied to AI product adoption and workflow automation traction.

Pattern: Classic post-earnings gap-up — +15.6% on a sub-$8 stock with $146M turnover signals a real guidance-beat reaction, not a low-float squeeze.

↓ FCEL -11.19%

$21.66 · Mid-cap · $194M traded

Why: FuelCell dropped on a comparison piece favoring Bloom Energy in the clean-energy space, with no fresh company news to offset the relative-weakness framing.

Pattern: Looks like noise inside a volatile clean-energy name — -11% on $194M turnover without a hard catalyst fits the high-beta mean-reversion profile of the group.

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

↑ SPCE +36.42%

$6.18 · Small-cap · $1.1B traded

Why: Virgin Galactic surged on flight-testing restart news compounded by SpaceX IPO excitement, with momentum screens picking up the move as a top pick.

Pattern: Textbook small-cap momentum breakout — +36% on $1.06B turnover (~10x typical) is the high-relative-volume thrust quant breakout filters key on.

↓ ASTS -14.79%

$113.41 · Small-cap · $5.4B traded

Why: AST SpaceMobile sold off sharply after a Blue Origin rocket explosion spooked space-sector sentiment, dragging satellite and launch-adjacent names lower in sympathy.

Pattern: Event-driven gap-down on $5.4B turnover — sympathy selling from an unrelated incident often sets up mean-reversion if the underlying business is unaffected.
