STMPA heads into its October 29 earnings with the stock up sharply on the month yet nursing a 4% single-day pullback, while a quiet but notable shift in the lending market adds texture to what looks like a stock caught between recovering sentiment and lingering fundamental doubt.
The most interesting development this week is not the price move but what is happening in the borrow market. Availability has tightened sharply from a position of extreme looseness. Three weeks ago, availability was effectively uncapped, running above 9,000% as barely anyone was borrowing stock. It has since compressed to 1,213%, still generous in absolute terms but down 35% in a single week. The direction of travel is clear: more shares are being pulled from the lending pool as the earnings date approaches. Cost to borrow remains low at 0.77%, barely changed over the month, so this is not a squeeze in any classic sense. It is more a quiet build in short-side interest ahead of a catalyst that has burned buyers badly before.
That history matters. The most recent earnings print, in July 2026, sent the stock down nearly 20% on the day and a further 2% over the following week. The prior print, in May, moved the other way, gaining 6% on the day and 9% over five days. The asymmetry of those outcomes, a near-vertical drop versus a modest recovery, explains why borrow demand is creeping up three weeks before the next release even as the stock itself has rallied 11% over the past month to close at EUR 49.90. Peers are not offering much comfort either: IFX fell 5.8% on Wednesday alone, BESI dropped 8.5% on the day and is down more than 8% on the week, and SMHN shed over 10% across the week. STMPA's 6.4% weekly gain looks increasingly like an outlier in a sector under pressure.
The positioning picture is, however, far less aggressive than the earnings history might suggest. The ORTEX short score sits at 28.97, up from 26.6 two weeks ago but still in the lower third of the range, indicating no concerted bear campaign. The short score rank for the stock is in the 93rd percentile for being un-shorted relative to peers, meaning dedicated short sellers are not piling in. EPS momentum scores are strong: the 30-day reading ranks at the 88th percentile and the 12-month forward earnings growth estimate ranks at the 91st percentile. The price-to-earnings multiple has expanded by about 1.1 turns over the past month to 23.5x, and EV/EBITDA has dipped to 10.4x as the stock rallied while estimates held. Bulls point to the multiple expansion as a sign the market is beginning to price in a recovery from the inventory correction that has depressed results through 2025 and into 2026. Bears counter that the July print, where Q3 revenue of roughly $4.2bn represented a 7% sequential decline, showed the correction is not yet complete, with automotive and industrial demand still soft.
The ownership structure limits the risk of a disorderly move in either direction. The controlling shareholder STMicroelectronics Holding N.V. accounts for 28% of shares, a large inert block. BlackRock holds a further 5.7% and recently added a token 107,000 shares. Jane Street's 1.8% position, built from essentially nothing in the most recently disclosed period with an addition of 13 million shares, is the most notable recent flow and reads more as a liquidity-driven or structured trade than a directional call. Insider activity since July has been restricted to small unpriced administrative transfers by executive committee members, none of which carry signal value.
The next three weeks reduce to a single question: whether October 29 shows the inventory correction is bottoming or extending. With borrow availability tightening into the date, the EPS momentum score running near its highest in a year, and the last comparable print delivering a 20% single-day drop, the setup is asymmetric and the market knows it.
