Shopify shares jumped 16.98% on Wednesday to close at $144.24, after the company beat second-quarter revenue estimates with 34% year-over-year growth. Three months earlier, Shopify reported the identical 34% growth rate for the first quarter and the stock fell 16% instead, as investors fixated on rising expense guidance rather than the top line. The nearly opposite reactions to comparable results show how much a single day's stock move can hinge on which narrative dominates that week, rather than on the underlying business itself.
