2330 closes the week at TWD 2,400, up 1% on the day and fractionally positive over the trailing five sessions, but the more interesting move has been in the borrow market, where cost to borrow has whipsawed sharply and reversed the easing trend noted in last week's note.
The borrowing story is worth unpacking. A week ago, CTB had fallen to 0.45% — the lowest point since late June — and the direction of travel looked clearly downward. That reversal has now been fully unwound. CTB jumped to 0.70% on Tuesday, its highest reading since mid-August, representing a 22% rise over the week and an 11% rise over the month. The move is notable because it contradicts the trend described here on August 19. To be precise about the data: the August 19 note reported CTB falling to 0.45%; it has since more than tripled from its August 19 trough of 0.17% and now sits back in the range that prevailed through most of early August. The wider lending picture remains untouched. Availability is at its theoretical ceiling — the pool of lendable shares is so large relative to short demand that borrow supply is not a constraint in any practical sense. The short score has barely shifted, moving from 25.2 to 25.2 over the past week with no acceleration. Positioning remains the opposite of stressed.
The Street picture is unchanged from recent weeks, and analyst data in the snapshot is too stale to draw on. Valuation multiples give a cleaner read on how investors are pricing the name: the trailing PE has drifted to roughly 18.7x, down slightly over the past month, while the price-to-book ratio of 6.5x has edged marginally higher. The dividend score ranks in the 99th percentile of the universe — a reflection of TSMC's consistent cash return history, though the most recent dividend data available dates to 2022 and should not be read as current guidance. The short score rank of 96 out of 100 indicates that, on a relative basis across the ORTEX universe, this name carries almost no short-side pressure — consistent with everything else in the lending data.
Institutional ownership shows the same slow accumulation pattern. Capital Research added roughly 8.5 million shares in the period to end-July. BlackRock added 8.4 million. FMR (Fidelity) added 5.2 million. T. Rowe Price added 11.5 million — the largest incremental addition among the top holders in the latest reporting period. None of these are dramatic in percentage terms against the overall float, but the direction is consistent: large global asset managers have been adding, not trimming. Insider activity has been similarly steady but modest, with two vice presidents — Yuan Lipen and Tien Bor-Zen — running small regular purchases through July and August totalling roughly $1.3 million in net value over 90 days. The trade significance scores are low (3 out of 10), and the dollar amounts are small relative to the company's scale, so these read as routine participation rather than a signal.
The peer picture this week cuts against TSMC's relative resilience. Correlated names across Japanese and Taiwanese semiconductor equipment and design — including 3711 and 6789 — have declined 1–5% on the week, while TSMC has held near flat. That divergence is worth monitoring: when correlates sell off and the index name holds, the question is whether the index name catches down or correlates recover. The Q3 earnings date of October 16 sits seven weeks out — the next substantive catalyst for the thesis to be tested.
