Share buybacks matter for many reasons, including earnings-per-share boosts, dilution offsets, tax efficiency, shareholder leverage, and signals of management confidence. They matter much more for big tech companies because the industry is in the midst of a shift that amplifies these signals.
The shift is from traditional, asset-light models reliant on software revenue toward heavy investment in infrastructure and data centers. Those investments weigh on cash flow today through upfront costs and on future earnings through depreciation, maintenance, and upgrades. The question is which companies can maintain or accelerate capital returns despite that, and which can't, because that matters for share price action.
