Like Darwin, we believe that variance is the real fact and the mean is something more abstract.
Accepting the variance is not easy. Everybody wants to earn money without risk, even though there will be nothing to win in the lack of risk (volatility).
Still, almost everybody predicts the next expected value, not the new variance. Same variance could lead to different means, same expected value could come as result for different variances.
What it is important here, it’s the net variance that one can’t mitigate alone. Think about that and use it to YouR own advantage.
