Premarket Volume Scan

Market Narrative

**May 28, 2026 Premarket Scan: ASTC Dominates Volume as Macro Events Loom** ASTC leads today's volume rankings with 146.3 million shares traded on a massive 459% gap to $13.81, showing a 90.8% premarket range that signals extreme volatility ahead. While the gap percentage is impressive, the exceptional volume makes this the clear top candidate for momentum traders using a shares only strategy. NVDA follows with 168.3 million shares but only a 1.05% decline to $212.6, presenting a potential VWAP play if the stock breaks its tight 1.17% premarket range on earnings or sector news. NOK and RDW round out the volume leaders with 123.9M and 121.3M shares respectively, with NOK showing a 4.74% decline and RDW posting an 8.89% gain. Today's macro calendar features Core PCE Price Index and Prelim GDP data, both critical for market direction and likely to drive additional volume in mega-caps like NVDA and INTC. Given the mixed premarket action across major names, expect VWAP strategies to work well on macro-driven reversals, while ASTC's wide premarket range suggests waiting for HOD/LOD breakouts rather than chasing the gap. Volume leaders without directional bias include BRTX, AIM, and SNGX, which may offer cleaner technical setups once the macro data hits. Focus on shares only strategies across all candidates due to limited options liquidity in the current environment.
