# Market Competitiveness > 来源:https://uqer.io/community/share/54b5c2f1f9f06c276f651a17 来一个奇葩无厘头的市场竞争策略 ## 策略思路 某一行业的几大龙头股票,在稳定时期此消彼长 ## 策略实现 + 股票池:选择一行业内的流动性比较好的龙头股票;例如三家自助品牌汽车,长安、比亚迪和长城,以下按照三只股票情况讨论 + 观察某一天时,股票价格和该股票在过去几天内平均值的关系 + 如果两只股票下跌,则预测另一只股票上涨;如果两只股票上涨,则预测另一只股票下跌 + 如果某天三只股票中的两只较其平均值有较大幅度下跌,而另一只股票较其平均值比较稳定不变,则买入后面这只比较稳定的股票 + 如果某天三只股票中的两只较其平均值有较大幅度上涨,而另一只股票较其平均值比较稳定不变,则卖出后面这只比较稳定的股票 ```py
