One of my favorite exercises in our process is the use of “mystery charts.” Essentially, we take out the x and y-axes and and all labels to eliminate any biases. The chart can be any security in any asset class on any timeframe on an absolute or relative basis. It can even be inverted.
The point here is to not guess what it actually is (though most of you will try), but instead to think about what you would do. Buy, Sell, or Do Nothing?
