想在成千上万只股票里挑出能持续上涨的 “好苗子”，却总纠结 “选业绩好的？还是估值低的？”本期内容就用通俗视角，拆解量化投资的核心黑话 ——“因子”，帮你跳出选股迷茫。因子不是随便的 “选股技巧”，而是股票收益的 “营养成分表”：能精准拆解一只股票的长期表现，且必须闯过五关才能被认可 —— 经得起几十年牛熊的 “持续性”、跨美股 A 股的 “普适性”、换市盈率 / 市净率定义仍有效的 “稳健性”、算上交易成本还能赚钱的 “可投资性”，以及有经济学逻辑的可解释性。但找到因子只是第一步：直接用 PE 选低估值股，会不小心重仓银行股（天然 PE 低）；用高 ROE 选好公司，又会偏向大盘股 —— 这就是因子被 “行业、市值” 污染了。于是有了市值中性化和行业中性化的方法。最后，通过 “排序分组+ 多空组合”，就能画出因子收益率曲线，看清这个因子到底能不能赚钱，帮你彻底吃透量化黑话，掌握专业选股的底层逻辑。【在这里找到我们】WeChat：quantfan_100（添加进听友群）微信公众号：Quantide 量化风云小红书：Quantidebilibili：Quantide
