Aspirin Count Theory

Aspirin Count Theory

A somewhat tongue-in-cheek theory stating that stock prices and aspirin sales are inversely related. That is, when stock prices are rising, aspirin sales are falling and vice versa. The idea behind this theory is that when stock prices are rising, fewer people are under stress, and, therefore, have less need for aspirin; likewise, when stock prices are falling, more people need aspirin and therefore buy it. The aspirin count theory has never been seriously tested.
