"Whatever stock you buy will go up," the demon had said, and it had not lied.
So you started buying at random. Aerospace companies that turned out to have military contracts. Pharmaceuticals that profited from epidemics and addiction. Companies that lowered costs as inequality brought down wages and corruption and ignorance made a mockery of environmental regulations.
Exactly a year after your profitable summoning, a nervous angel no longer confident in your ability to notice things explained to you in a vision that the stocks went up through external events <i>because</i> you had bought them. By then the idea of a fortune that did not grow every year felt like its own version of damnation, and you kept reinvesting in more companies whatever you did not spend on luxury beyond human senses or stamina.
