Special expertise, when it does exist and that is rare but does sometime happen, is subject to one of three outcomes:what is your opinion of binary options?
Everybody learns it and the special expertise vanishes.
The expertise is banned by law.
The expertise involves personality traits that are rare. The Value Line caused an exception to the Efficient Market Theorem for this very reason. It is the Fundamentalist exception. Most people can't figure out company reports well enough to gain an advantage relative to using a simple stock screen. Also patience is required. The people who use Value Line are a small minority of all investors who fairly rapidly get too big to usefully use the service so the service is pricey as well.
NADEX claims widespread special expertise in ads that barely stay within what can legally be claimed.
