Is Min Cao’s TSM share purchase a discretionary open-market trade?

The 66-share acquisition is not a discretionary trade; it was made under the Employee Stock Purchase Plan. Footnotes explain the ESPP administrator purchased shares pursuant to terms predetermined by the issuer, meaning the timing and amount followed plan rules rather than individual market timing.

Employee Stock Purchase Plan financial

"Common Shares purchased by the administrator of the issuer's Employee Stock Purchase Plan ("ESPP") on behalf of the filer"

An employee stock purchase plan is a company program that lets workers buy shares through small payroll deductions, often at a discount to the market price and after a set offering period. Think of it like a workplace savings plan that turns into ownership: it encourages employees to share in the company’s success and can create predictable buying or selling of stock that investors watch because it affects supply, demand and employee incentives.
