I have never traded stocks before and don't understand the logic of stock trading, but I've noticed that many stock traders around me use unconventional methods to buy and sell stocks. One of my uncles once shared his stock-picking techniques with me, claiming that he could predict the extent of an uptrend or downtrend based solely on the height of the K-line. Other traders on this forum subscribe to the 'buy on dips' strategy, arguing that if the market falls by 10%, they should buy 20%, and if it falls by 20%, they should add to their position by 40%. Some even claim that the global stock market's meltdown signals an imminent A-share rally. Furthermore, others invest in companies without having any understanding of the underlying business or market trends. I find these methods illogical and believe that buying stocks should be based on a thorough understanding of government policies and the company's value and prospects. I don't understand the connection between K-line patterns and company value, nor do I understand how 'buy on dips' strategy fails to consider the possibility of the company going bankrupt. I'm not mocking these methods, I'm just curious to know why they seem to work for some people. Can anyone shed some light on how these techniques generate profits?
