In the turbulent financial market, "bull market" and "bear market" are not only two professional terms, but also two natural breaths of market vitality. They are like the alternation of day and night, the cycle of the four seasons, constituting the most essential operating law of the capital market. The truly mature investors are not the prophets who can accurately predict every turning point, but the wise ones who can objectively and calmly examine the market and completely abandon the mentality of luck. The frenzy of a bull market often makes one's heart surge. Asset prices are steadily rising, market sentiment is generally optimistic, and wealth effects are spreading like ripples. In such an atmosphere, investors are prone to the illusion that upward movement is the only direction of the market, and profit becomes an easy and inevitable outcome. However, objectively viewing a bull market means recognizing that it is simply the result of a combination of economic cycles, loose liquidity, and market sentiment. It will eventually usher in its own limit, and the excessively inflated foam will always burst. If in a bull market, only profits are seen and risks are ignored, then the so-called "profits" are just temporary figures on the books. The bleak bear market is a severe test of human nature. When the market continues to decline, panic spreads, and once confidence is shattered, two extreme mindsets are most likely to arise: either completely despairing and leaving the market, or hoping for a "miracle reversal" with luck. However, an objective view of the bear market requires us to understand that it is also a necessary process for the market to self correct - overestimation is digested, foam are squeezed out, and risks are released. It is precisely in such a cold winter that true value investors begin to quietly lay out, because they deeply understand that a bear market not only means risk, but also nurtures the seeds of the next cycle. Leaving no trace of luck is the highest criterion for market survival. Luck is the biggest enemy of rational thinking - it allows us to comfort ourselves with "this time is different" when risks arise, wait for "tomorrow will rebound" when mistakes occur, and choose "wait and see" in the face of evidence. This kind of psychology is essentially an escape from reality, building investment decisions on wishes rather than facts. The cruelest and fairest aspect of the market is that it will never change its trajectory based on individual desires. The true market wisdom lies in observing the ups and downs of the market with a detached attitude, neither being fanatical due to rising prices nor panicking due to falling prices. We need to recognize that the bull bear transition is an inherent attribute of the market, rather than an external force that we need to resist. Just like a sailor who cannot control the wind direction but can adjust the sails, mature investors do not try to resist the market, but follow its laws and make rational responses at every market stage. This objective perspective is not innate, it needs to go through the baptism of the market, the lessons of failure, and more importantly, continuous introspection and cultivation. When we can calmly view every rise and fall, without feeling regretful or anxious about being trapped, and when our decisions are based on facts and logic rather than hope and fear, we truly understand the language of the market and qualify to dance with it.
