August 10, 2026 Biggest Stock Movers
ABCL (AbCellera Biologics Inc.) surged 34.78% to $9.34, the session's top gainer. The move came on no specific headline in today's data; the stock gapped higher on heavy volume, likely a news-driven or short-covering event. The stock remains down sharply from prior-year levels despite today's pop.
OBX (Obsidian Therapeutics) rallied 27.27% to $35.00. The biotech name saw a second consecutive day of outsized gains, though no catalyst was provided in the data. Trading volume was well above the 30-day average, indicating institutional participation.
NESR (National Energy Services Reunit) climbed 23.33% to $35.79, riding the energy complex's strength. With WTI crude up 5.24%, oilfield services names were the clear leadership group. NESR's move outpaced the sector ETF's 4.66% gain, suggesting stock-specific momentum on top of the macro tailwind.
FSLY (Fastly, Inc.) jumped 20.86% to $27.75. The edge-cloud company has been volatile in 2026; today's move came on no earnings release in the data, pointing to a possible partnership announcement or analyst upgrade driving the gap higher.
QH (Quhuo Limited) rose 15.85% to $5.08, extending a recent run in small-cap Chinese ADRs. The move was not tied to any index-level catalyst, as the broader Russell 2000 fell 0.56% today.
On the downside, BTDR (Bitdeer Technologies) crashed 20.08% to $8.695, leading losers. The bitcoin mining stock fell alongside a slide in crypto-related equities, though no specific company news was in today's data. AXTI (AXT Inc) dropped 16.67% to $73.81, and COHR (Coherent Corp.) fell 14.24% to $325.15 — both semiconductor supply-chain names hit hard as the technology sector declined 0.88%. SIMO (Silicon Motion) lost 9.96% to $230.61, and NYAX (Nayax Ltd.) fell 9.95% to $62.00.
What Moved the Stock Market August 10, 2026
No CPI, PPI, jobs, GDP, or retail sales prints were scheduled or released today per the data provided. The dominant macro driver was a 5.24% spike in WTI crude to $82.28, which powered the energy sector to a 4.66% gain and pushed the 10-year Treasury yield up 0.84% to 4.70%. The dollar firmed 0.15% to 99.75 while gold rallied 2.97% to $4,469.50 — a combination suggesting a geopolitical supply shock or a weather-related disruption to oil production, though no specific headline was provided. The VIX rose 3.76% to 15.46, confirming that the crude spike injected a fresh dose of uncertainty into an otherwise quiet tape.
Earnings Highlights: August 10, 2026
No major earnings reports were included in today's data feed. The top movers — ABCL, OBX, NESR, and FSLY — all moved on non-earnings catalysts, while the losers (BTDR, AXTI, COHR) also showed no earnings data. This was a light reporting day; the tape was driven entirely by sector rotation and commodity flows.
What to Watch Tomorrow: August 11, 2026
- Earnings: Keep an eye on any technology and semiconductor names following today's sharp selloff in COHR and AXTI — pre-announcements or guidance updates could extend the sector's weakness.
- Energy follow-through: Watch whether WTI crude holds above $82.00; a sustained breakout would keep XLE momentum alive, while a reversal could trigger profit-taking after today's 4.66% surge.
- Treasury auction: With the 10-year yield at 4.70%, any weak demand at tomorrow's auction could push yields higher, pressuring XLU and XLRE, which fell 1.10% and 1.29% respectively today.
- Fed speakers: No Fed speakers were cited in today's data, but with the VIX ticking up to 15.46, any scheduled commentary on inflation or the path of rates will be closely watched by rate-sensitive sectors.
