Does that work for the "no"s? I didn't buy or sell any stock yesterday; with that definition of "inverse", wouldn't I have to perform all possible actions? For any time, stock and amount, the inverse of inaction would be "yes, buy/sell X shares of stock Y."

It wouldn't work because you don't have an unlimited amount of money. So it's impossible to turn all "no's" into "yes" for the inverse strategy.

In addition, buying/selling is not a binary action per se for stocks because you need to specify an amount.
