Income / OppHub America angle
Not a trade tip — ways to use the insight outside the market.
- Look into enterprise hardware buyers who might benefit from lower component pricing if flash memory gets cheaper.
What would break this thesis
- SanDisk beats upcoming earnings or competitors report strong demand that disproves the slowdown theory.
