Taiwan Semiconductor Manufacturing Company has clawed back 1.6% over the past week to TWD 2,250, recovering from the turbulence of early April — and the most telling detail is that short sellers appear to have given up on the downside well before the rally.
The lending market makes that retreat unmistakable. Cost to borrow has collapsed 40% in a week, reaching just 0.43% annually — a fraction of where it was in early April, when it briefly spiked above 3.9% during the tariff-driven selloff. Availability is near fully loose: borrow is effectively unrestricted, and availability against outstanding short interest is negligible because there is almost no short interest to speak of. The ORTEX short score of 25.2 ranks in the 96th percentile for low short-side pressure — meaning almost no comparably sized stock in the universe has a less aggressive short-selling setup. Short interest has been pinned at effectively zero throughout the past six weeks, with no movement in the lending pool regardless of the macro headlines swirling around Taiwan and semiconductor trade policy. The message from the borrow market is clear: there is no meaningful short-selling thesis being pressed at TWD 2,250.
The valuation picture explains part of that restraint. The trailing P/E has expanded to 21.3x, up roughly 2.5 points over the past month — a meaningful re-rating in a short space of time that arrived alongside a 24% one-month price surge. Price/book moved similarly, adding nearly a full point to 7.0x. The EV/EBITDA multiple has actually eased to 13.8x as earnings estimates track higher, suggesting the market views the move as partially fundamental rather than purely speculative. EPS momentum scores support that read: the 30-day momentum factor ranks at the 75th percentile, and earnings surprise ranks at the 54th percentile — not exceptional, but constructive. Analyst data is too stale to cite reliably, so the market is essentially pricing TSMC on its own reported fundamentals rather than on Street consensus adjustments.
Institutional ownership tells a story of quiet accumulation rather than hot-money chasing. BlackRock added 21 million shares in the most recent reporting period, bringing its stake to 3.45% of outstanding. Vanguard added 11.7 million shares. Capital Research added 9.1 million. These are slow-moving, index-adjacent flows — but the direction across multiple major holders is consistently additive, not trimming. The National Development Fund holds 6.4% and is unchanged, providing a stable anchor. Insider activity is modest: four Vice President-level purchases in late March at prices around TWD 14,400 per ADR equivalent, with a net 90-day value of roughly $387,000 — small enough in absolute terms that it reads more as conviction maintenance than a directional signal.
The last earnings print on April 16 produced a 1-day move of -2.4%, with the five-day reaction flat at zero. That pattern — a brief dip absorbed within the week — has been consistent across recent quarters. The next scheduled report is July 16, which leaves a full ten weeks for the macro backdrop (US chip export rules, US-China tariff trajectory, NVIDIA AI-related capex) to evolve before the next fundamental test.
What to watch: the gap between the rapid valuation re-rating and the still-modest EPS momentum trajectory will be the central tension into July — specifically whether the April/May price move pulls earnings estimates higher fast enough to keep the expanded multiples looking defensible.
