Forget margin or options. Here's how the pros trade ACHRArcher Aviation shares climbed 11.19% over the past week as investors cheered fresh progress toward getting its electric air taxi business off the ground. The key catalyst was a major regulatory milestone: the U.S. Federal Aviation Administration has now fully accepted 100% of the company’s “Means of Compliance” for its Midnight aircraft, a crucial step on the path to type certification. This strengthens confidence that Archer can begin commercial operations in the U.S. and UAE around 2026, supported by policy tailwinds such as the White House eVTOL pilot program.
At the same time, heavy institutional buying helped fuel the rally. Sumitomo Mitsui Trust Group disclosed a purchase of more than 1.4 million shares, pushing institutional ownership above 50% and signaling that large investors see long-term value despite recent volatility and a still-negative year-to-date performance. While a filing from Vanguard created some short-term noise, its index funds remain among the biggest holders, reinforcing the view that the shareholder base is broad and committed.
Analysts and high-profile investors are increasingly highlighting what they view as a valuation gap after the earlier selloff, noting that Archer Aviation is trading close to its roughly $2 billion cash pile while holding an indicative $6 billion order book and partnerships with several major airlines. Wall Street’s consensus rating remains Strong Buy, with expectations for significant upside if Archer can execute on scaling production and turning regulatory and policy wins into real-world operations and revenue. For now, the combination of regulatory progress, institutional support, and perceived undervaluation is giving the stock fresh momentum after a difficult start to the year.
