eBay Q3 Earnings Preview: Activist, Index Bid, and a Stock Giving Back Ground

eBay pulled back 1.5% over the past week to $118.62, underperforming a peer median that edged up roughly 0.6%, with ETSY flat and GRPN up more than 3% over the same stretch.

The short side has been retreating, not building. Short interest dropped 4.4% over the week to 3.5% of the free float, and has now fallen more than 6% over the past month. Borrowing costs are negligible at 0.51%, and availability is extraordinarily loose at 5,687%, meaning the lending pool holds roughly 57 shares available for every one currently borrowed. That is well above the 52-week floor of 900%. None of this points to a crowded short or any squeeze dynamic. Options positioning is similarly relaxed: the put/call ratio of 0.86 is fractionally below its 20-day average of 0.88, suggesting no unusual demand for downside protection ahead of Wednesday's print.

The analyst community is split on whether the recent momentum is durable. Morgan Stanley raised its target to $132 on October 12, maintaining Overweight, while Wells Fargo simultaneously trimmed its target to $91, staying Underweight. That gap captures the core debate. Bulls point to the second quarter's 15% GMV growth, 23.7% advertising revenue growth, and the Depop acquisition adding a younger demographic to the platform. The bear case is that the Depop deal costs roughly 2.5 points of EPS this year and creates a 2-point drag on operating income growth, raising questions about whether the turnaround is self-sustaining or acquisition-dependent. The consensus mean price target of $116.91 is fractionally below the current price, reflecting a street that is broadly constructive but not uniformly so.

The most structurally notable feature of the ownership register remains GameStop Corp.'s 13D activist stake, last disclosed at 9.8% of eBay's shares. Five separate filings between May and July signal an active, not passive, position. GameStop holds the standing to press for strategic changes, though its specific agenda has not been publicly disclosed. Separately, ORTEX puts the probability of eBay joining the Nasdaq-100 at the December 2026 Annual Review at 38%. The stock needs to close above $125.91 to reach the entry line, roughly 6.1% above Monday's close. If that level is reached, estimated tracker buying flows would total $4.8 billion over approximately 8.8 days of normal volume. That remains a candidate scenario, not a confirmed outcome.

Wikipedia attention for eBay is running at a z-score of 2.0 against its own prior 90 days, a high reading that reflects elevated retail interest into the print rather than any fundamental signal.

Wednesday's report will test whether organic marketplace momentum can be distinguished from acquisition-driven headline growth, and whether management's full-year GMV guidance of 11.5% to 12.5% FX-neutral growth still holds after stripping out Depop's contribution.
