All engagement strategies, in the abstract, can be classified into these two categories. To follow the strong and always strong is to believe in momentum and bet on the inevitable return of the mean with time. This is not only a trading strategy, but also two simple principles when it comes to work, choosing an industry, and even judging the times. The joy and twists and turns in fate are both accidental and inevitable.

If the accumulated momentum is too large, it will inevitably be released, whether upward or downward, and in this process, this momentum will definitely be self-reinforcing.

Why do some people not mean revert.

Positive feedback and positive cash flow are more important than imagined, and they can resist mean reversion. And a true understanding of the market and human nature can also confront it.

The first market will always exist, and the second human nature will always repeat.
