股市交易是当前重要的经济活动之一,股评亦成为当前分析把握股市行情的渠道,在指导理财、投资、消费方面发挥巨大作用。从股评的本质看,对股市行情的分析应包含“两个基本点”:即一个质的变化、一个量的变化。质的变化即下跌、上涨的变化,量的变化即增幅、跌幅大小的变化。能准确、有效地揭示这两个基本点也就达到了股市分析的目的。股评的作用是指导投资人正确、理性地投资,最终形成收益。这就要求股评分析是客观理性、准确无歧义的。然而客观世界丰富多样,存在着大量模糊的现象,模糊语的使用正是为了准确表达而存在。我们讨论模糊语使用的恰当与否,都要以股评的作用为前提,能够准确表达观点、指导投资而使用的模糊语则是恰当的,否则就是模糊语的滥用,造成了理解的模糊。纵观当前的股评,很多专家的评论在关键信息点上使用模糊语,造成与此目的截然相反的结果。
Stock market trading is one of the most important economic activities at present, and stock assessment has also become the current channel of analyzing stock market quotations, playing a significant role in guiding financial management, investment and consumption. From the nature of stock assessment, the stock market analysis should include “two basic points ”: that is, a qualitative change, a change in volume. Quality changes that fall, rising changes, the amount of change that increase, decrease the size of the change. Accurate and effective disclosure of these two basic points also reached the purpose of stock market analysis. The role of stock assessment is to guide investors to invest properly and rationally and eventually generate revenue. This requires stock analysis is objective and rational, accurate and unambiguous. However, the objective world is rich and varied, and there are a large number of vague phenomena. The use of vague terms precisely exists for accurate expression. We discuss the appropriate use of vague language, should be the premise of the role of stock assessment, to accurately express their views, guidance investment and the use of vague language is appropriate, otherwise it is the vague language abuse, resulting in vague understanding. Throughout the current stock review, many expert comments use vague terms at key points of information, resulting in the opposite result.
