If you don't know what the Wall St. "Cheat Sheet" is, please google "Wall Street Cheat Sheet" What the Wall St. Cheat Sheet is, its the psychology of the a market cycle,
when we start with the market cycle, we go start with disbelief, then as it rallies, we experience hope, optimism, belief, thrill and finally at the peak we get euphoria.
As the market starts to break down, we get complacency, anxiety, denial, panic, capitulation, and anger. once we hit depression, that is the point of maximum financial opportunity. (the lowest point before the market cycle restarts) and after the "depression phase, we start again, with "disbelief" and so forth.
we see some similarities of this in the 2013 bear market, and the current (2018) bear market.
