Context
ESPP purchases are often periodic, pre-authorized plan buys funded by payroll deductions and therefore are routine. While purchases can be interpreted more positively than sales, plan-based acquisitions are not a direct signal of discretionary insider market timing. The reported price here reflects conversion from New Taiwan dollars to USD.
