Tower Semiconductor heads into its Q1 2026 earnings release with short sellers cutting exposure at the fastest pace of the past six weeks, even as the stock slipped 2% on the week.
The short interest story is the standout this week. At 2.38% of free float on May 12, the position is down 34% in a single week — a move from roughly 3.5% to 2.4% that has erased most of the build-up that ran from mid-April through early May. That earlier peak, near 3.7% of float, was itself the highest level of the 30-day window. The speed of the unwind is notable: bears cut roughly 1.3 million shares in two sessions. Borrow conditions corroborate the retreat. Cost to borrow is a very relaxed 0.48%, down 7% on the week and off 23% over the month. Availability has loosened dramatically alongside the de-shorting — borrow is no longer under any meaningful pressure. The ORTEX short score has dropped from 38.8 on May 4 to 31.4, reflecting the sharp improvement in the stock's lending-market profile.
Options are calm and, if anything, mildly bullish. The put/call ratio is 0.71, fractionally below its 20-day average of 0.73, and the z-score of −0.54 signals nothing elevated in either direction. The 52-week PCR range runs from 0.06 to 1.16, so current positioning sits well inside neutral territory. Together with the short unwind, the options market paints a picture of investors removing hedges rather than adding them.
The Street view on Tower is broadly cautious, though targets have been moving higher all year. Benchmark's Cody Acree lifted his price target to $230 in late March — a big jump from $165 — while keeping a Buy rating. That was the most recent action. Earlier in Q1, both Barclays and Wedbush raised their targets too, though neither shifted their neutral-equivalent stances. With one Hold on record and a consensus mean target around $173, the stock at $220.83 is trading well above the analyst consensus — a gap that bears watching, as it implies the Street has not kept pace with the share price appreciation. The PE stands at 60x on a trailing basis, with EV/EBITDA near 33x and off about 2.3 points over the past month. The strongest factor reading is the 12-month forward EPS estimate momentum, ranked in the 95th percentile — the market is pricing in meaningful earnings growth.
Institutional ownership adds an interesting wrinkle. T. Rowe Price added a material 4.7 million shares in Q1 2026, making it the second-largest reported holder at 4.3% of shares. BlackRock added a further 458k shares through April. Both moves suggest large-cap active and passive buyers were building into this year's rally. On the other side, Point72 trimmed by 1.2 million shares through year-end 2025, and Senvest cut by 1.6 million. The two-way institutional traffic reflects the underlying bull-bear debate on the name.
Bulls point to Tower's Silicon Photonics and Silicon Germanium capacity expansion, positioning the company to serve AI data center and RF infrastructure demand. Bears flag that RF SOI weakness in the low-end handset market creates a near-term drag, and that the heavy capex cycle — with most new capacity not qualified until Q3 2026 — compresses near-term free cash flow. Among the closer-correlated peers in the semiconductor equipment and specialty chip space, ONTO fell 6.8% on the week, MKSI gained 10.5%, and NVMI — the highest-correlation US name in the snapshot — dropped 4.4%. The divergence across the peer group reflects stock-specific rather than sector-wide positioning.
The key watch from here is whether the short covering was earnings-driven or a structural re-rating of the position — and whether the stock can sustain a premium to analyst targets now that results are in hand.
