DislikedThe most efficient way to trade, theoretically speaking, is to find some unique stuff and never ever say anything about it to anyone. Take the money and run.Ignored
I agree.
As soon as everyone knows about a successful method or strategy, it's possible for others to anticipate it.
If they can anticipate it, they can enter the trade before everyone that uses those common strategies, and the market dynamics will change.
In english, this implies that the price will start to adjust before everyone using those common strategies has a chance to act -- making those strategies less effective.
