Stock market analysis requires many disciplines. Unlike, physics, for example, it’s not rocket science. Hell, it’s not even science. But while physicists and astrophysicists understand more and more about how the universe works, there is much more that they don’t understand. For every theory that they confirm, more questions arise.
They say that approximately 80% of the mass of the universe is “dark matter.” They don’t know what it is. And there’s “dark energy,” that they don’t understand either. They see their effect, but they can’t see the cause, and don’t know what either of them is. So they observe and measure the effects, and make predictions and develop theories based on that.
