Archer Aviation (ACHR) shares fell 10.91% to $4.33 today. The primary driver of the decline appears to be a broader market pullback in the electric vertical takeoff and landing sector, occurring despite recent corporate announcements and continued institutional buying.
The stock slid even as Cathie Wood’s ARK Investment Management added to its position in the company. ARK purchased approximately 180,500 shares, representing about $8.79 million in Archer Aviation stock. This purchase marked the second consecutive day of buying by the fund, with Archer leading ARK’s purchases by share count during the week.
Separately, Archer Aviation announced a multi-year partnership with Formula One. The agreement allows the company to showcase its Midnight eVTOL aircraft at Grand Prix events, with plans to eventually fly spectators. Despite this strategic move and the institutional support, the stock faced downward pressure. Peer companies in the eVTOL space also declined, with Joby Aviation falling 4% and EHang dropping 2%.
Over the last eight sessions, the stock had moved up 4.8%, rising from $4.13 to $4.33 before today’s drop. The 52-week tape shows the stock printed two fresh 52-week highs and 16 fresh 52-week lows on November 12, 2026.
Insider activity has been predominantly negative. In the last 90 days, there were zero buys and six sells totaling $1.7 million.

With no scheduled earnings date provided in the current data, investors will likely monitor the breadth of coverage and the market’s reaction to the new Formula One partnership. The continued accumulation by ARK Investment Management may serve as a counterweight to the recent insider selling activity.
