Investors can make judgments based on their basic market expectations, but even if their judgments are accurate, the timing and intensity of market trends caused by these expectations may still far exceed your expectations. This actually proves how difficult it is to accurately predict the market - even if it relies on a bunch of proven correct judgments. Because if market fluctuations are a big deal, then "fact" is just one of the ingredients.
Is investment a balance between long-term and short-term, between oneself and the market, or between expectations and reality. From a micro perspective, investment is also a balance between data and perception, an absolute and relative balance. Of course, investment is still a balance between long and short positions, a balance between risk and return, and a balance between persistence and abandonment. Investment is a balanced art. Only by understanding balance and trade-offs can one be considered mature and not burdened by stubbornness.
