用数学公式来描述经济领域中出现的客观规律和现象，这叫经济领域中的数学模型。 这和用数学公式来描述自然现象是一样的道理，如牛顿的万有引力公式和定律。用数学分析方法来指导投资者买卖股票，从而保证进入股市的资金的风险为零，这叫零风险博弈数学模型
零风险博弈理论根据市场的变化和零风险前提下的利润最大化可推导出很多种零风险博弈数学模型，它们分别是下面情况的组合：
均分法博弈数学模型
金字塔法博弈数学模型
止损法博弈数学模型
上升通道-KDJ-滚动资金-金字塔-博弈数学模型
下降通道-3TM函数-止损法-金字塔-博弈数学模型
调整通道-KDJ指标-止损法-金字塔-博弈数学模型
股价底部-3TM-金字塔-博弈数学模型
股价高位-KDJ指标-止损法-金字塔-博弈数学模型
长线投资-中线投资-三段三阶-博弈数学模型
股票市场是投机的金融市场，投机是股票市场的基石和润滑剂。进入股票市场的公司、投资机构和投资者，都是由于“投机”二字而进入的。进入股票市场的大众必须认真理解这一点，因为今后所论述和引入的新技术分析理论都是建立在“投机”这个基础上的。只要深入理解“投机”的内涵，投资者在股市的风险就会降到最低。本章节着重论述这个观点。
世界上成功的商业和企业几乎都是上市公司。没有股票市场也就没有今天世界的繁荣。一句话，没有投机就没有股票市场，也就没有今天社会繁荣。全世界的知名企业，更离不开股票市场。
投机是股票市场和市场经济活动的基石和润滑剂。对于这一提法，可能会有很多不同的观点，正是因为具有不同的观点和看法，这个问题一直是世界上经济学家和政治批评家争论不休的问题。这里引用美国纽约大学教授、著名经济学家威廉J鲍默尔（WILLIAMSＪBAUMAL）关于股市“投机”一词的一段论述：
Dealings in securities are often viewed with hostility and suspicion because they are thought to be an instrument of speculation. When something goes wrong in the market, say, when there is a sudden fall in price, speculators are often blamed. The word speculators is used by editorial writers as a term of strong disapproval, implying that those who engage in the activity are parasites who produce no benefits for society and often do it considerably harm.
Economists disagree vehemently with this judgment. They say that speculators perform two vital economic functions:
1.Speculators sell protection from risk to other people, much as a fire insurance policy sells protection from risk to a homeowner.
2.They help to smooth out price fluctuations by purchasing items when they are abundant (and cheap) and holding them and reselling them when they are scarce (and expensive). I that way, speculators play a vital economic role in helping to alleviate and even shortages.
Speculators enable farmers or producers of metals and other commodities whose future price is uncertain to get rid of their risk. A farmer who has planted a large crop but who fears its price may fall before harvest time can protect himself by signing a contract for future delivery at an agreed-upon price at which the speculator will purchase the crop when it comes in. In that case, if the price happens to fall, it is the speculator and not the farmer who will suffer the loss. Of course, if the price happens to rise the speculator reap the gain—that is the nature of risk bearing. The speculator who has agreed to buy the crop at the preset price, regardless of market condition at the time the sale take place, has, in effect, sold an insurance policy to the farmer. Surly this is a useful.
