Markets are governed by two things: math and story.

Math is simple. It’s reality, the fundamentals and the underlying supply and demand for whatever’s being traded. The story is where human psychology enters the picture. It’s what causes people to extrapolate wildly, move in herds, and swing from bouts of extreme pessimism to embarrassing optimism. Markets can whipsaw wildly based on story alone, though in the end, raw math eventually wins out.
