FormFactor Shorts Retreat Sharply Ahead of Earnings

FormFactor enters its October 28 earnings release with short sellers having cut their positions at one of the steepest rates of the past year, even as the stock itself is down about 1% on the week.

Short interest dropped by more than 18% in the seven days to October 27, falling to roughly 2.54 million shares, or 3.3% of the free float. That one-week decline is 1.7 standard deviations below the company's typical weekly move, meaning the unwind is unusually large by the stock's own history. Looking back further, short interest had been running near 3.1 million to 3.2 million shares through most of September and October, so the move lower this week represents a genuine repositioning rather than noise. The most recent FINRA fortnightly figure, settled October 15, put short shares at 2.62 million, consistent with the direction of travel.

The borrow market tells a complementary story. Availability is exceptionally loose: there are roughly 53 times as many shares available to borrow as there are shares currently short, a reading that has widened sharply from around 30 times in mid-September. Cost to borrow has ticked up about 9% over the week to 0.47%, but that remains very low in absolute terms and far below anything that would constrain a short seller from establishing a position. Options pricing does not show unusual hedging demand either: the put/call ratio of 0.78 is running slightly below its 20-day average of 0.84, a shade more call-leaning than the recent norm rather than defensively positioned.

The Street is mixed but has been moving upward on the name. Deutsche Bank initiated coverage at Buy with a $200 target at the end of September. Freedom Capital Markets raised its target from $64 to $140 in early October, though kept its Hold rating. Evercore ISI holds an Outperform with a $150 target. TD Cowen is at Hold with a $100 target, the most cautious published figure. The mean analyst price target at around $140 to $150 sits well above the current price of $106.85, implying material upside on most models. The bull case centres on AI-driven demand for advanced probe cards, the Teradyne $300 million strategic investment, and long-term revenue targets of $1.6 billion by 2030. The bear case rests on semiconductor equipment cyclicality, customer concentration, and the structural retreat of China revenues, which fell to $58 million, or 7% of total, in FY25. Factor scores tilt positive: EPS momentum over 30 days ranks in the 89th percentile and analyst recommendation differential in the 91st, though the forward earnings yield and valuation multiples rank more modestly, with a PE near 28.6x that has compressed by about 8 points over the past 30 days.

CEO Mike Slessor has been a consistent seller under a 10b5-1 plan, disposing of shares in August, September, and again on October 14 at prices between $104 and $132. Over the past 90 days insiders have net sold roughly 46,700 shares for approximately $5.5 million. All the filed trades carry the 10b5-1 designation, meaning they were set up under a pre-arranged schedule rather than reflecting discretionary conviction. One director, Kelley Steven-Waiss, sold 2,100 shares on September 3 without a 10b5-1 plan, though at a relatively modest $202,000. Net institutional ownership is broadly stable: BlackRock holds about 13.4% and added marginally in Q3, while Vanguard vehicles collectively hold around 12% after a corporate restructuring of how their stake is registered. EARNEST Partners trimmed its position from 6.3% to 4.8% as of mid-August.

The ORTEX alt data layer flags a spike in retail attention: Wikipedia page views and ORTEX stock page traffic combine for a z-score of 4.2 against the company's own 90-day history, as of October 19. This measures attention, not a revenue or earnings indicator, but the reading does confirm that the name is drawing more eyes than usual heading into the release.

With the earnings call scheduled for this evening, the data worth tracking is whether the short cover seen this week extends in the days following the release, and how the borrow availability figure responds to any fresh positioning.
