过去进行的研究的资本资产定价模型或CAPM认为，在均衡的情况下，安全性的预期收益将是衍生的beta的正线性函数。这个测试版已经足够了，它将被用来全面衡量它的预期回报。实验研究证明了正贝塔关系在超额收益方面的合法性和有效性。这些都是在过去的40年里发生的。股票回报的平均值和它的安全回报指数被用作股票市场投资组合预期收益的替代。后来的研究表明这些关系的证据不一致。在一些研究发现中，它已经暗示了beta和最终平均关系之间的关系是平的。例如，在东京证券交易所(TSE)的案例中，研究表明，beta和平均回报的关系在几个月内并不重要(Fletcher,2000)。在几个月的时间里，他们被观察到具有负面意义。

这也在斯里兰卡证券交易所被观察到。另一位研究经济学家的研究也支持了类似的发现。Tang & Shum(2003)的研究表明，在科伦坡证券交易所(CSE)的案例中，负的beta – return关系是无关紧要的。这就产生了一个问题，如果关于beta和回报之间的不一致的证据没有系统地相互关联(Lau,Lee，和McInish,2002)。这些相互矛盾的结果形成了贝塔和回报，导致了在金融市场波动期间收益的聚集。人们已经发现，在上升的市场中，贝塔回报必须是乐观的，在下跌的市场中也会被减少。基于此，betas的关系非常重要。在beta和回报之间建立的条件关系一直是不同市场的焦点。

The Capital Asset Pricing Model or CAPM of the research undertaken in the past contends that in cases of equilibrium, the expected returns on the security would be a positive linear function of the beta that is derived. The beta is sufficed and will be used to measure it comprehensively of the expected returns. The experimental research has shown the legitimacy and valid positioning of positive beta relationship in excess returns. These were followed in last 40 years. The average of stock returns and its index of security returns are used as substitution for the returns that are expected of stock market portfolio. Research that was conducted at a later time indicates the inconsistent evidence of these relationships. In some research findings, it has been alluded that the relationship formed between beta and the final average relationship is flat. For example, in case of Tokyo Stock Exchange (TSE), the research states that beta and average return of relationship are not important in all months (Fletcher, 2000). During some months, they are observed to be negatively significant.

This was also observed in the Sri Lankan Stock exchange. Similar findings are bolstered in the research conducted by another research economist. Research by Tang & Shum (2003) specifies that negative beta -return relationship is insignificant in the case of Colombo Stock Exchange (CSE). This has arisen to the question if the inconsistent evidence on the relationship between beta and returns are not systematically related to each other (Lau, Lee, and McInish, 2002). These contradictory results that have formed beta and return have led to the focus of the aggregation of returns during the financial market fluctuation. It has been discovered that beta -returns must be optimistic during the up markets and be reduced during the down markets. Based on this, the relationship between the betas is significant. The conditional relationship that is forged between the beta and return has been the focus in the different markets.
