Taiwan Semiconductor

On an ordinary day over the last month of trading, TSM has moved about 1.85%, making it about as volatile as most of the stocks Kinzan tracks (their median is 1.81%).

Measured against its own habit, today is a +0.8σ day: the kind of session it has most weeks.

It sits near the top of its 24-hour range of 410.04–418.82, measured on hourly closes.

The New York block (13:00–22:00 UTC) did most of the work — roughly 57% of the movement over the last 24 hours.

Over the last 60 sessions of daily returns, it has moved most closely with NDX (+0.79, a strong relationship), and most inversely to VIX (−0.56).

Its last close is at the 62nd percentile of its own last 82 sessions, and its 20-day volatility at the 47th.

Market read: TSM is hitting the top of its range, showing persistent strength throughout the New York session.

What it is

TSMC is a contract manufacturer of semiconductors. It sells no chips under its own name; it fabricates designs supplied by customers, including most of the large fabless companies in the US market. The pure-foundry model it pioneered is what allows a chip designer to reach the most advanced process without owning a factory. It also sells advanced packaging, which bonds accelerators to high-bandwidth memory and has become a bottleneck of its own. Most production is in Taiwan, with plants built or under construction in the United States, Japan and Germany. The ordinary shares trade in Taipei; the symbol here is the American depositary receipt listed in New York, each representing a fixed number of those shares.

What drives it

Utilisation and leading-edge pricing set the profit line. A foundry carries enormous fixed costs, so gross margin swings with how full the factories are, and the newest nodes command the highest prices while they remain scarce. Capital-expenditure guidance is read twice: as the company’s view of demand and as an order book for its equipment suppliers. Over all of this sits a geopolitical overlay no other large chip share carries to the same degree: tension across the Taiwan Strait, and US rules on which customers may receive advanced chips, can move the receipts with no change in demand. Revenue is also published monthly.

How it trades through the day

Two lines trade in two blocks. The Taipei shares trade in the Asia block, roughly 01:00 to 05:30 UTC all year; the receipt trades in the New York block, 13:30 to 20:00 UTC during US daylight time and 14:30 to 21:00 UTC in winter. Quarterly results come out in the Taiwanese afternoon, so the receipt’s first reaction is in pre-market dealing and at the opening auction. The receipt has historically traded at a premium to the local shares, a gap that moves with foreign demand.

What it tends to move with

It sits at the centre of the semiconductor complex, downstream of the lithography and equipment makers and upstream of the accelerator and handset designers it builds for, so news at either end reaches it. Its results arrive early in each reporting season and set the tone for the group. At home it is by far the heaviest weight in the Taiwanese benchmark.
