The idea
I believe AI agents are about to do the price-shopping humans never bother with, constantly hunting for the best yield, quote, fare, or plan. That kills margins built on customer inertia and rewards the businesses that are already the cheapest to run. So this basket leans into everyday low-price retail, brokerages and yield platforms, direct insurers, and airlines and telecom plans, with the biggest weights on the clearest cost leaders and a 10% cash reserve to add on dips.
