为什么仓位管理比选股更重要？ Why Is Position Management More Important Than Stock Selection? 大多数散户投资者花90%的时间研究「买什么」，却花不到10%的时间思考「买多少」。 Most retail investors spend 90% of their time researching "what to buy," yet spend less than 10% of their time thinking about "how much to buy." 但在专业投资者的世界里，这个比例恰恰相反——选对股票只是成功的一半，如何分配仓位才是决定长期回报的核心变量。

什么是高抛低吸？ What Is "Sell High, Buy Low"? 高抛低吸是最基础也是最重要的交易理念之一——在股价相对低位买入，在股价相对高位卖出，通过反复操作降低持仓成本或锁定利润。 "Sell high, buy low" is one of the most fundamental and most important trading concepts — buying when the stock price is at a relatively low level and selling when it is at a relatively high

为什么止损是投资中最难的事？ Why Is Setting a Stop-Loss the Hardest Thing in Investing? 从技术层面看，止损非常简单——当股价跌至你预设的价位时卖出，仅此而已。 From a technical standpoint, a stop-loss is very simple — sell when the stock price falls to your predetermined level, and that is all there is to it. 但从心理层面看，止损是投资中最困难的事情之一，因为它需要你在最痛苦的时刻做出最理性的决定。 But from a psychological standpoint,

为什么市场情绪比基本面更能解释短期股价？ Why Does Market Sentiment Explain Short-Term Stock Prices Better Than Fundamentals? 很多投资者有过这样的经历：一家公司发布了明显超预期的季报，股价却在第二天大跌；或者明明整体经济数据不好，股市却持续上涨。 Many investors have had this experience: a company releases a quarterly earnings report that clearly beats expectations, yet the stock price falls sharply the next day; or the overall economic data is clearly

什么是支撑位与压力位？ 支撑位是股价下跌过程中遇到的”地板”——在这个价格区域，买盘力量足以阻止股价继续下跌，股价往往在此止跌反弹。压力位则是股价上涨过程中遇到的”天花板”——在这个价格区域，卖盘力量足以阻止股价继续上涨，股价往往在此遇阻回落。 理解支撑位和压力位是专业交易者最核心的技能之一。掌握这个框架，你可以做到两件在大多数散户眼中看似矛盾的事情——高买高卖，以及低买低卖，并且两种策略都能盈利。 支撑位和压力位从哪里来？ 支撑位和压力位并非凭空出现，它们来自市场参与者的集体心理和历史成交记录。 历史高点和低点——股价曾经到达的历史高点往往成为未来的压力位，历史低点往往成为未来的支撑位。原因是在历史高点买入的投资者套牢后，往往等待股价反弹至成本价时卖出，形成卖压。 整数关口——$100、$200、$500等整数价位在心理上对交易者有重要意义，往往形成天然的支撑或压力。例如英伟达突破$100、特斯拉突破$300，都曾引发市场的广泛关注和方向性突破。 均线位置——如第一篇所述，20日、50日、200日均线本身就是动态的支撑和压力位。 成交密集区——历史上大量成交发生的价格
