One of the challenges in anyone’s life, especially in one’s job, is figuring out what’s really going on. For me, and anyone involved in the financial sector, this is especially complicated because there is an infinite amount of data, interpretations, arguments, and conclusions that will tell you up, down, right, left, buy, and sell—all at the same time.
The physical sciences have been dealing with this problem for a long time and refer to it as isolating the signal—the meaningful information you need—from the noise, the random events that can mask the signal.
