Archer Aviation Surges 2.40% on $500M Volume 256th in Active Stocks as Strategic and FAA Advances Fuel eVTOL Sector Optimism
Archer Aviation (ACHR) surged 2.40% on October 1, 2025, with a trading volume of $0.5 billion—up 35.1% from the prior day and ranking 256th among active stocks. The rise followed strategic updates and operational developments that reinforced investor confidence in the electric vertical takeoff and landing (eVTOL) developer.
Recent activity highlighted Archer’s progress in regulatory milestones, including a key certification step with the FAA, and expanded partnerships for infrastructure deployment. Analysts noted these factors as pivotal in differentiating Archer from peers in the nascent eVTOL sector, though market volatility remains tied to broader economic signals and sector-specific risks.
Backtesting frameworks for the stock require clarifications on implementation parameters. Current constraints include universe definitions (e.g., U.S. equities only or expanded to ETFs/ADRs), execution timing (close-to-close or open-to-open), and weighting conventions. Given the platform’s single-ticker processing limits, multi-asset strategies must either approximate via synthetic indices or rely on correlated ETFs, with the latter offering faster deployment but less precision.
