Archer Aviation Stock Plunges on 23 Volume Drop as Liquidity Ranks 334th in U.S. Market

Archer Aviation (ACHR) closed 0.54% lower on Sept. 26, with a trading volume of $320 million — a 23.23% decline from the previous day’s level. The stock ranked 334th in market liquidity among U.S. equities, reflecting subdued investor activity despite ongoing strategic developments.

Recent corporate updates highlighted a potential partnership expansion in regional air mobility solutions, though details on financial terms or deployment timelines remain undisclosed. Analysts noted the lack of concrete monetization frameworks as a limiting factor for near-term valuation optimism. Operational updates also indicated delays in regulatory certification for its fourth-generation electric vertical takeoff and landing aircraft, which could impact 2026 revenue projections.

Backtesting of a high-volume trading strategy involving U.S. equities since 2022-01-03 would require custom portfolio modeling beyond standard tools. Alternative approaches include using S&P 500 ETF proxies like SPY/RSP or analyzing individual stocks’ historical volume thresholds to simulate performance. These methods offer approximations but cannot fully replicate a 500-ticker daily rotation strategy without dedicated execution infrastructure.
