Taiwan Semiconductor Manufacturing Company heads into its Q3 results on October 15 with the local shares down 3.7% on the week to TWD 2,490, a reversal from last week's rally to TWD 2,585, and the earnings reaction history suggests the print itself is the harder event to read.
The borrow market tells a story of extraordinary calm. Availability remains effectively unlimited, with over 7 billion shares available against negligible short demand. The short score of 25.2 ranks in the 96th percentile of stocks with the least short pressure, and utilisation has barely moved, holding at 0.11%. Cost to borrow has ticked up 31% on the week to 0.36%, continuing the pattern flagged in prior notes: percentage moves sound significant, but the absolute level is still firmly low and well below the 0.43% seen in early September. None of this points to growing conviction against the stock. Short sellers are not building positions ahead of the print.
The valuation picture has shifted modestly since last week's note. The trailing P/E has eased from 19.1 to 18.1, a week-on-week decline of roughly one point as the share price pulled back. EV/EBITDA has also drifted lower, now at 12.1 versus 12.8 the prior week. Both moves reflect the price correction rather than any change in fundamentals. The factor profile remains strong: TSMC ranks in the 96th percentile on short score, the 90th percentile on days-to-cover, and the 99th percentile on dividend score. The analyst data in the snapshot is stale and not quoted here, but the ADR note published October 12 flagged a Street mean target of $571.51 on the ADR with Barclays holding an Overweight at $665, so the institutional bias has been firmly bullish into this event.
The earnings history adds a note of caution. The July 2026 Q2 print produced a sharp negative one-day reaction of 6.1% on the local shares, with a further drift of 1.4% over the subsequent five trading days. The Q2 reaction is the most recent comparable data point available. Taiwan-listed peers also weakened on the day, with 3711 down 2.9% on the week and 6789 and 2406 both off more than 7% over the same period, suggesting broader semiconductor sector pressure rather than TSMC-specific positioning.
On the company's own data, TSMC's monthly revenue filings with the Taiwan Stock Exchange show year-on-year growth ranking in the top quintile of the Taiwanese listed universe, with the latest reading covering September. The dataset has not yet accumulated enough history for ORTEX to test whether it leads the company's reported quarterly figures, so it is colour rather than a forward signal. The next quarterly print is tomorrow.
What matters most in the next 24 hours is whether management's forward guidance on advanced node demand holds up against a week of share-price weakness that has not been matched by any deterioration in the borrow market or short positioning.
