NEW YORK, January 5, 2026, 08:04 ET — Premarket
- ACHR up about 0.6% in premarket trade after an 8.1% jump at Friday’s close
- A Form 144 filing shows CTO Tom Muniz plans to sell up to 125,000 shares under a 10b5-1 plan
- Investors are watching the 10 a.m. ET ISM factory survey and the next earnings update expected in late February
Archer Aviation shares ticked higher in premarket trading on Monday after a regulatory filing showed the company’s chief technology officer plans to sell stock. The shares were up about 0.6% at $8.18, after closing up 8.1% on Friday at $8.13. 1
Why it matters now: Archer is a high-beta, early-stage aviation name, and trading in it can swing quickly when investors scan for clues on funding, insider behavior and sentiment across speculative growth stocks.
The filing is a classic “read-through” item for momentum traders. It does not mean the shares have been sold, but it can put a spotlight on potential supply as the stock tries to hold recent gains.
A Form 144 is a notice filed when an insider plans to sell restricted or “control” securities under SEC Rule 144 — essentially a heads-up that a sale may be coming. The form also discloses whether the seller is using a Rule 10b5-1 plan, a pre-set trading program meant to reduce the risk of trading on material nonpublic information.
The Form 144, dated Jan. 2, shows CTO Tom Muniz proposed selling up to 125,000 Archer Class A shares with an aggregate market value of about $1.0 million, or roughly 0.02% of the shares outstanding listed on the notice. The filing also lists a 10b5-1 plan adoption date of Sept. 29, 2025, and notes a prior sale of 90,648 shares on Nov. 17, 2025. 2
Archer is developing electric vertical takeoff and landing aircraft — known as eVTOLs — aimed at short urban flights and other commercial and defense uses. 3
The stock’s move came alongside strength in other eVTOL-linked names before the open. Joby Aviation rose about 0.7% in premarket trade, while Vertical Aerospace added about 1.2%. 4
Broader risk appetite was steady, with U.S. index futures slightly higher as investors digested weekend geopolitical developments. “For markets it’s not an oil-price earthquake,” said Lale Akoner, global market analyst at eToro. 5
Macro headlines are also on the radar for rate-sensitive growth stocks. The Institute for Supply Management’s manufacturing survey is due at 10:00 a.m. ET on Monday, and investors are looking toward this week’s labor-market updates, including Friday’s U.S. nonfarm payrolls report. 5
But the downside scenario is straightforward: insider-sale disclosures can weigh on thin conviction, especially in pre-revenue companies where the path to certification and commercialization is still the main driver of long-term value. Any renewed volatility in growth stocks can amplify moves in names like Archer.
