Archer Aviation shares declined 5.66% Wednesday to $5.50 without a company-specific catalyst, as rising Treasury yields and weaker major equity indexes drove a broader retreat from riskier growth stocks. The 10-year U.S. Treasury yield reached approximately 4.84%, its highest closing level in close to three years, after the Treasury Department announced a $6 billion bond buyback that fell short of market expectations. ACHR is down roughly 27% year to date and 14.1% since its August 10 earnings announcement, when Archer reported a $0.34 per-share loss and $5 million in revenue, above the $1.94 million analyst consensus. Cathie Wood’s ARK Invest purchased 575,700 shares through the ARK Innovation ETF on September 8, worth approximately $3.35 million based on Tuesday’s closing price. Archer is also advancing its No Roads flight demonstration program, which included a piloted round trip between Salinas and Hollister, California, and is progressing with the planned acquisition of Boeing subsidiaries Wisk Aero, Insitu and SkyGrid. Six analysts covering the stock over the past three months maintain a Strong Buy consensus and an average price target of $11.60, implying potential upside above 110%, although Weiss Ratings recommends Sell and the broader tracked-analyst consensus is Hold with an $11.50 average target. Insiders sold approximately $1.14 million of shares over the past 90 days, including transactions by CFO Priya Gupta and Eric Lentell, with some sales tied to taxes on vested equity awards. ACHR rose approximately 1.4% in Thursday premarket trading.
