Taiwan Semiconductor Manufacturing
A maker of the tiny chips that power the world's smartphones, computers, and game consoles, TSMC is the world's largest independent semiconductor foundry. It manufactures the processors that companies like Apple and Nvidia design — the A-series chips inside iPhones and Nvidia's graphics processors. Founded in 1987 by Morris Chang, TSMC pioneered the 'pure-play foundry' model, with its first factory on the campus of Taiwan's Industrial Technology Research Institute.

Select a row to see that insider’s individual transactions. Sum of the holdings confirmed in the 12 months before this insider's last filing. A Form 4 reports a holding per line — held directly, or through a named trust, partnership or foundation, and in each share class separately — never a person’s total. Lines not restated in that time are left out and shown apart: an active filer restates what they still hold, so a line they did not restate is more often an entity since renamed, whose shares a successor line reports too. An amber marker means some were left out.
Net open-market activity over all recorded history: -180.8K shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
