"consider yourself superior to people who believe in astrology"

I mean...at some point a spade HAS to be a spade for this type of thing

100 on the tone. I can't stand it either.

Focusing on the point: let's all agree astrology is dumb and immature, sure. However, if your goal is to actually understand what moves a market (and presumably make money), I think it rather inexperienced and ruinous to ignore the effects of millions of people, who may be open to being influenced by astrological events, participating in the market.

I mean, astrology is widely known to be nonsense.

True, but you'll be surprised at how many people want astrology and stuff like crystals and scented stones and magical beans across the United States. It's huge and truly a contest between literacy and the belief system.
