英文摘要：
  Price movements of stock market are not totally random. In fact, what drives the financial market and what pattern financial time series follows have long been the interest that attracts economists, mathematicians and most recently computer scientists [17]. This paper gives an idea about the trend analysis of stock market behaviour using Hidden Markov Model (HMM). The trend once followed over a particular period will sure repeat in future. The one day difference in close value of stocks for a certain period is found and its corresponding steady state probability distribution values are determined. The pattern of the stock market behaviour is then decided based on these probability values for a particular time. The goal is to figure out the hidden state sequence given the observation sequence so that the trend can be analyzed using the steady state probability distribution( ) values. Six optimal hidden state sequences are generated and compared. The one day difference in close value when considered is found to give the best optimum state sequence.

中文摘要：
股票市场的波动并不完全是随机的。事实上，推动金融市场的因素以及金融时间序列的模式一直吸引着经济学家、数学家和最近的计算机科学家[17]。本文提出了一种利用隐马尔可夫模型（HMM）对股票市场行为进行趋势分析的方法。这种趋势一旦在特定时期出现，将来肯定会重演。找出某一时期股票收盘价的日差，并确定其相应的稳态概率分布值。然后根据特定时间的这些概率值来决定股市行为的模式。目标是找出给定观测序列的隐藏状态序列，以便使用稳态概率分布（）值分析趋势。生成并比较了六个最优隐状态序列。当考虑到一天的闭合值差异时，可以得出最佳状态序列。
