问财量化选股策略逻辑
选股逻辑为：选择换手率在3%~12%之间、买一量大于卖一量、10天内涨停天数大于2的股票。
选股逻辑分析
该选股策略主要从交易活跃度、市场参与度、短期涨势等角度综合考虑，选取具有一定上涨潜力的股票。
有何风险？
该选股策略过于依赖短期涨势因素，可能导致选出的股票具有一定的投机性质，而非投资价值。此外，涨停股票存在短期大幅调整的风险，因此选股时需要谨慎。
如何优化？
除了选股时考虑交易活跃度和短期涨势外，增加其他技术指标，如均线系统、趋势指标等，可以提高筛选出有较好表现的股票的概率。此外，可以结合公司基本面、宏观经济等因素进行选股筛选，更加全面地综合考虑选股因素。
最终的选股逻辑
在换手率在3%~12%之间，买一量大于卖一量，10天内涨停天数大于2的股票中，按照涨幅从高到低排序，选取前50只股票。

ORDER BY A.CHG DESC
WHERE ROWNUM <= 50;
