我们之前给大家分析过本周的日线级别支撑位，今天市场正好触及该位置。我们预测的第一个支撑位是 3330点左右，而今天最低达到3332.49点。盘中分时图显示，在该位置获得支撑后市场开始反弹。连续 两天的缩量也表明短线反弹随时可能到来，只是节奏比我们预期的稍慢一些。 （原标题：和讯投顾刘金锁：跌跌不休何时止？） 今日市场成交量继续缩量，K线也继续创出新低。虽然今天并未出现大跌，但在昨天止跌信号的基础 上，今天的表现仍可视为一个值得期待的信号。从短线来看，KDJ指标随时可能触发反弹。然而，今天 的缩量其实是一个积极信号，说明空头并没有大举做空。 综合来看，我们建议大家在端午节之前保持相对谨慎的态度。即使指数出现反弹，理论上向上的空间也 较为有限，因此节前对指数操作仍需谨慎。个股方面，建议大家按照自己的节奏操作，风险相对可控。 但需要注意的是，当前科创板连续阴跌，部分个股也呈现出阴跌态势。对于那些前期日线连续阴跌而未 出现快速下跌的个股，可能还需要等待一次快速下跌后才能真正止跌企稳。因此，个股分化依然较为严 重。 从个股表现来看，今天市场整体表现尚可，涨跌个股基本持平。沪市上涨个股1100多家，下跌个股约 1000多 ...
