Investing is an art and highly emotional and subjective.

When buying stocks, if your buying decisions are based on"insiders' information or rumours" and not sound analysis, then you are gambling. Many investors enter the market when stocks prices are high (lacking of confidence to enter beforehand when prices were low). Once the stocks market crash, they tend to sell out their shares out of fear and pessimism, swearing to "chop off their fingers" and never enter the stocks market again. If such situation happens, all their previous gains may be wiped out and suffered a loss.

Investing is an art and highly emotional and subjective. Subjectivity is largely controlled by our emotions. There are times when we are optimistic or pessimistic. If we are unable to control our emotional weakness, we are unlikely to become successful investors.

To be successful, you must first understand yourself, in particular your emotions and the degree of pressure you can tolerate.

The investors should also analyse the country's economic prospects together with the earnings outlook of the major listed companies.

It is imperative that you like Mathematics as the sound mathematical knowledge plays a key role in investment.

灵活运用乖离率{转}

乖离率是指股价与平均移动线之间的偏离程度,通过百分比的形式来表示股价与平均移动线之间的差距。如果股价在均线之上,则为正值;如果股价在均线之下,则为负值。乖离率最早来源于葛兰维的平均线定律,它的理论基础主要从投资者心理角度来分析。因为均线可以代表平均持仓成本,利好利空的刺激,造成股价出现暴涨暴跌。股价离均线太远,就会随时有短期反转的可能,乖离率的绝对值越大,股价向均线靠近的可能性就越大,这就是乖离率提供的买卖依据形成的原因。

  乖离率是一种简单而又有效的分析工具,但在使用过程中基期的选择十分重要。如果基期太短,反应过于敏感,如果基期太长,反应过于迟钝。从市场经验来看,10日平均移动线作为基期效果较好。以下跌为例,10日乖离率通常在-7%至-8%时开始反弹。考虑到这个数值的安全系数不高,一般情况下,更为安全的进场时机应选择在-10%至-11%之间。同样出于稳健,短线在上涨时可以在+8%附近卖出。

  此外,在乖离率的应用时,应该结合不同情况灵活运用才能提高盈利机会。第一,对于风险不同的股票应区别对待。有业绩保证且估值水平合理的个股,在下跌时乖离率通常较低时就开始反弹。这是由于持有人心态稳定不愿低价抛售,同时空仓投资者担心错过时机而及时买入的结果。反之,对绩差股而言,其乖离率通常在跌至绝对值较大时,才开始反弹。第二,要考虑流通市值的影响。流通市值较大的股票,不容易被操纵,走势符合一般的市场规律,适宜用乖离率进行分析。而流通市值较小的个股或庄股由于容易被控盘,因此在使用该指标时应谨慎。第三,在股价的低位密集成交区,由于筹码分散,运用乖离率指导操作时成功率较高,而在股价经过大幅攀升后,在机构的操纵下容易暴涨暴跌,此时成功率则相对较低。
