Joby Just Dropped 27% in a Month: Did JOBY Stock Just Find a Bottom?

Electric air taxi developers have spent the past month in a group selloff, and the damage in this corner runs far deeper than anything in large-cap stocks. Joby Aviation (NYSE:JOBY | JOBY Price Prediction) stock is down 0.4% to $4.68 this afternoon, extending a 27% slide over the past month. That muted session hints that the selling could be slowing down, although a single day proves little.

Meanwhile, Archer Aviation (NYSE:ACHR) shares are down 32% over the past month to $3.87, a deeper drop than Joby stock posted and the steepest of the group. EHang Holdings (NASDAQ:EH) stock is down 29% over the past month to $3.35, landing between its two U.S. rivals. Shares of Joby, Archer and EHang have fallen in tandem over the past month, a pattern that points to sector-wide pressure on air taxi stocks.

Two benchmarks show how unusual those declines are. The ARK Autonomous Technology & Robotics ETF (CBOE:ARKQ) is down 11% over the past month. Over the same stretch, the SPDR S&P 500 ETF Trust (NYSEARCA:SPY) is down 2%, so the broad market hasn’t collapsed.

Archer Leads a Sector-Wide Air Taxi Slide

Joby shares have dropped alongside Archer and EHang shares, the clearest sign that the selling is hitting air taxi stocks as a group. When Joby, Archer and EHang shares all fall sharply within one month despite different aircraft programs and timelines, the pressure appears to come from how the market values the whole category. That framing matters for the bottom question, because a decline driven by the group can also reverse with the group.

Archer stock stands out on the downside, with a steeper monthly loss than Joby stock. EHang stock lands in between, so Joby shares have held up better than both rivals even after their own sharp fall. For EHang, the upside argument rests on an international fast-track program and an authorized share buyback; the bear case is a more cautious Chinese regulatory stance after a piloted aircraft accident, which prompted it to withdraw full-year revenue guidance.

Joby and Archer Face the Same U.S. Gatekeeper

Joby and Archer are both developing piloted electric air taxis that need certification from the Federal Aviation Administration before they can carry paying passengers in the U.S. That shared path ties Joby and Archer shares together, since a regulatory setback or breakthrough can change expectations for both developers at once. Which developer reaches each regulatory step first remains the open question for Joby and Archer.

For Joby, the optimistic thesis rests on its relative resilience and on the direct benefit that each certification step brings to its own aircraft. On the bear side, aviation certification timelines can stretch, and air taxi developers spend heavily long before commercial service begins. Archer stock carries those same certification risks with a weaker monthly chart, which leaves more room for a rebound and stronger evidence of fading confidence at once.

Joby’s Next Certification Milestone Holds the Key to a Bottom

A muted session for Joby stock after a steep monthly slide leaves the bottom question open. One quiet day can signal seller exhaustion or simply a pause before another leg lower, and price action alone doesn’t proves which outcome this is. Steep sector selloffs often need several stable sessions before buyers recover confidence, and a single day falls short of that bar for Joby.

The coming test for Joby is whether it reaches its next certification milestone. Clear regulatory progress would give Joby stock a company-specific reason to separate from a group that has traded as one block over the past month. Investors can adjust their holdings carefully given that Archer and EHang shares have yet to meaningfully recover and a sector-wide slide may need a group-wide pause before any floor holds.
