怎样判断股票的底部？
在股票市场上，个股不可能会出现一直上涨的情况，也不可能一直下跌下去，一般下跌到一定程度之后，会出现反弹的情况，那么，投资者如何判断股票已经到底部了呢？
本人喜欢以月线级别为基础判断。（以下均以月线考量作参考，用寒武纪为例子）
特征1.均线：
以月21均线为标准，启动前一直被月21均线压制着，没突破月21均线前都是底部区间，不宜介入。（上图黄线是月21均线
特征2.成交量：
以放量突破21月均线为标准，资金是股价上涨的决定因素，股价需要资金的推动，当资金放量突破21月均线代表行情要走出底部区间。如图1，寒武纪1月总成交20.2亿，2月份总成交170亿，2月股价收83.97元，放量突破21月均线75.37元。
特征3.月MACD底背离：
股价往下走，创新低，月macd指标绿柱收窄，往上走。
特征4.月线资金累积流入：
月线级别累计资金流入大于累计资金流出，净流入为正时，代表行情要走出底部区间。（上图紫色线为累计资金流入，黄色线为累计资金流出）
特征5.月线主力进场，吸筹明显：
明显的看到主力进场吸筹的红柱出现，红柱越高，出现的次数越多代表主力进场资金越多，后期推动股价上涨的动力越足，股票上涨的潜力越大，具体如上图所示。
综上所述：要判断一只股票是不是跌到了阶段性底部，我们可以结合股票的月21均线、月成交量、月macd底背离，月线资金累积流入，月线主力进场吸筹等5个方面进行综合判断。
最后附资金流入流出指标和主力行为指标代码：
